Application Precautions
5
• Do not apply voltages to the Input Units in excess of the rated input voltage.
Excess voltages may result in burning.
• Do not apply voltages or connect loads to the Output Units in excess of the
maximum switching capacity. Excess voltage or loads may result in burning.
• Disconnect the functional ground terminal when performing withstand voltage
tests. Not disconnecting the functional ground terminal may result in burning.
• Be sure that all the mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified in this manual. Incorrect tightening torque may result in malfunction.
• Double-check all wiring and switch settings before turning ON the power supply. Incorrect wiring may result in burning.
• Mount Units only after checking terminal blocks and connectors completely.
• Be sure that the terminal blocks, Memory Units, expansion cables, and other
items with locking devices are properly locked into place. Improper locking
may result in malfunction.
• Check the user program for proper execution before actually running it on the
Unit. Not checking the program may result in an unexpected operation.
• Confirm that no adverse effect will occur in the system before attempting any of
the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Resume operation only after transferring to the new CPU Unit the contents of
the DM Area, HR Area, and other data required for resuming operation. Not
doing so may result in an unexpected operation.
• Do not pull on the cables or bend the cables beyond their natural limit. Doing
either of these may break the cables.
• Do not place objects on top of the cables or other wiring lines. Doing so may
break the cables.
• Use crimp terminals for wiring. Do not connect bare stranded wires directly to
terminals. Connection of bare stranded wires may result in burning.
• When replacing parts, be sure to confirm that the rating of a new part is correct.
Not doing so may result in malfunction or burning.
• Before touching a Unit, be sure to first touch a grounded metallic object in order
to discharge any static built-up. Not doing so may result in malfunction or damage.
• Check the direction and polarity of all terminal blocks and connectors before
attempting to connect them.

What is a Control System?
A Control System is the electronic equipment needed to control a particular process. It may include everything from a process control computer, if one is used,
to the factory computer, down through the PCs (and there may be many of them
networked together), and then on down through the network to the control components: the switches, stepping motors, solenoids, and sensors which monitor
and control the mechanical operations.

A Control System can involve very large applications where many different models of PC are networked together or it could be an application as small as a single
PC controlling a single output device.

In the typical Control System example shown above, a PC controls the movement of the workpiece bed across two horizontal axes using Limit Switches and
Servomotors to monitor and control movement.
1-2
The Role of the PC
The PC is the part of the Control System that directly controls the manufacturing
process. According to the program stored in its memory, the PC accepts data
from the input devices connected to it, and uses this data to monitor the controlled system. When the program calls for some action to take place, the PC
sends data to the output devices connected to it to cause that action to take
place. The PC may be used to control a simple, repetitive task, or it may be connected to other PCs, or to a host computer in order to integrate the control of a
complex process.

Section 1-2
The Role of the PC
1-2-1 Input Devices
PCs can receive input from either automated or manual devices. The PC could
receive data from the user via a pushbutton switch, keyboard, or similar device.
Automated input could come from a variety of devices: micro-switches, timers,
encoders, photosensors, and so on. Some devices, like the Limit Switch shown
below, turn ON or OFF when the equipment actually makes contact with them.
Other devices, like the Photoelectric Switch and Proximity Switch shown below,
use other means, such as light or inductance, in order to get information about
the equipment being monitored.
Photoelectric Switch
Proximity Switch
Limit Switch
1-2-2 Output Devices
A PC can output to a myriad of devices for use in automated control. Almost anything that you can think of could be controlled (perhaps indirectly) by a PC. Some
of the most common devices are motors, Solenoids, Servomotors, Stepping
Motors, valves, switches, indicator lights, buzzers, and alarms. Some of these
output devices, such as the motors, Solenoids, Servomotors, Stepping Motors,
and valves, affect the controlled system directly. Others, such as the indicator
lights, buzzers, and alarms, provide output to notify personnel.

How Does a PC Work?
PCs operate by monitoring input signals and providing output signals. When
changes are detected in the signals, the PC reacts, through the user-programmed internal logic, to produce output signals. The PC continually scans the
program in its memory to achieve this control.

Programming
Device
A program for your applications must be designed, and stored in the PC. This
program is then executed as part of the cycle of internal operations of the PC.
Scanning Cycle
When a PC operates, that is, when it executes its program to control an external
system, a series of operations are performed inside the PC. These internal
operations can be broadly classified into the following four categories:
1, 2, 3...
1. Common (or overseeing) processes, such as watchdog timer operation and
testing the program memory.
2. Data input and output.
3. Instruction execution.
4. Peripheral device servicing.
Cycle Time
The total time required for a PC to perform all these internal operations is called
the cycle time. The flowchart and diagram on the following page illustrate these
internal operations for a typical PC.
Timing is one of the most important factors in designing a Control System. For
accurate operations, it is necessary to have answers to such questions as these:
• How long does it take for the PC to execute all the instructions in its memory?
• How long does it take for the PC to produce a control output in response to a
given input signal?
The cycle time of the PC can be automatically calculated and monitored, but it is
necessary to have an understanding of the timing relationships within the PC for
effective System design and programming.

CPU Rack
The following figures show the names of all the parts of the CPU Racks used in
C1000H and C2000H Systems. Note that the Backplanes used for each system
are different.
C1000H System
There are seven models of CPU Racks available for C1000H systems. Choose
a Backplane with 3, 5 (2 models), 6, 8 (2 models), or 9 I/O slots, depending on
your application. Connect the CPU Backplane to an Expansion I/O Rack via the
Expansion I/O Connector.

Expansion I/O Rack.
C2000H Simplex System
I/O Units
(3, 5, 6, 8, or 9 I/O Units depending
on the Backplane used)
CPU Power Supply
The C2000H Simplex CPU Rack is different from the C1000H CPU Rack in that
there are six slots available for I/O Units rather than eight. The CPU Rack for the
Simplex and Duplex Systems have a special slot, to the left of the I/O Units, for
an I/O Remove Unit. Connect the CPU Rack to an Expansion I/O Rack via the
Expansion I/O connector. For more details concerning the Simplex System,
refer to Section 3-3 C2000H Simplex System.

C2000H Duplex System
The C2000H Duplex CPU Rack is different from both the C1000H and C2000H
Simplex CPU Racks. The CPU Rack houses two CPUs and a Duplex Unit, learning no room for I/O Units. An additional Rack connected to the CPU Rack via the
Expansion I/O Connectors accommodates the I/O Units which would normally
be mounted to the CPU Rack. Note that two connecting cables are required to
connect the CPU Rack to the accompanying I/O Rack that houses the I/O Units.
Just like the Simplex System, the Duplex CPU Rack has a special slot for an I/O
Remove Unit, located on the I/O Backplane.

I/O Backplane
The I/O Backplane is always paired with the CPU Rack in a C2000H Duplex system. The I/O Backplane houses the I/O Units, which cannot be mounted to the
CPU Rack. Use two cables to connect the I/O Backplane to the CPU Rack. Two
PC Link Units and one Host Link Unit can be mounted to any of the six rightmost
slots on the I/O Backplane. Similar to the C2000H CPU Backplane, the I/O Backplane also has a special slot for an I/O Remove Unit. Use one cable to connect
the I/O Remove Unit on the I/O Backplane to the I/O Remove Unit on the Expansion I/O Rack.

Expansion I/O Backplane
The Expansion I/O Backplane shown in the following diagram, can be used to
expand the C1000H and C2000H Simplex and Duplex Systems. An Expansion
I/O Rack is just like a CPU Rack, except a CPU is not mounted. However, a
Power Supply is needed for each Expansion I/O Rack. There are three models
of Expansion I/O Backplane available. The Expansion I/O Rack shown below
can only be used with C2000H Systems. This Backplane has a special slot for
the I/O Remove Unit, which allows on-line I/O Unit exchange. two models are
available for C1000H PCs, with either five or eight slots.

I/O Control Unit
An I/O Control Unit must be mounted to the CPU Rack in order to connect the
CPU Rack to an Expansion I/O Rack. In C1000H and C2000H Simplex Systems, the I/O Control Unit is mounted to the CPU Rack. In the C2000H Duplex
System, the I/O Control Unit is mounted to the I/O Rack. An I/O Control Unit can
be mounted even if no Expansion I/O Rack is used.
2-8
I/O Interface Unit
An I/O Interface Unit is needed on each Expansion I/O Rack, in order to expand
the PC. If there is not an I/O Interface Unit on each Expansion I/O Rack, data
communication cannot take place. The I/O Interface Unit is mounted to the leftmost I/O position on the Expansion I/O Backplane.

File Memory Unit
When a File Memory Unit is connected to the PC, contents of the Program
Memory and data areas can be transferred to and from File Memory (FM). For
details on operating the File Memory Unit, refer to the C1000H/C2000H Operation Manual.
The Unit can be mounted to either of the six rightmost slots on the Rack.
2-10 Space Unit
The Space Unit is included with the I/O Backplane to fill the space between the
Power Supply and the rightmost Unit mounted on the Backplane. This Unit only
applies to the I/O Backplane used in C2000H Duplex Systems. When mounting
this Unit be sure to remove the bracket on the Backplane first.
2-11 I/O Remove Unit
The I/O Remove Unit is unique to C2000H Systems. When mounted to a Rack of
a C2000H System, the I/O Remove Unit allows standard I/O Units to be removed
or mounted while the CPU is operating. The I/O Remove Units on each Rack are
connected by an I/O Remove Unit Connecting Cable.
In order to mount an I/O Unit to or remove an I/O Unit from any of the Racks in the
PC system, a Programming Console must be used to release the I/O Unit from
the control of the CPU. For details, refer to the PC Operation Manual.
Depending on the combination of I/O Units, a failed standard I/O Unit can be
replaced without affecting the other Units in the system.
When mounting or removing the I/O Units, the terminal block does not need to be
rewired. Simply mount the I/O Unit to the Backplane and then the terminal block
to the I/O Unit. When removing the I/O Unit, remove the terminal block first and
then remove the I/O Unit from the Backplane.
When an I/O Unit is mounted or removed while the CPU is operating on a Backplane which has an Interrupt Input Unit mounted to it, the Interrupt Input
(mounted only to C1000H and C2000H Simplex PCs) will be ignored.
Note
1. Remember that only a standard I/O Unit can be mounted or removed during
operation.
2. An I/O Remove Unit must be mounted on every Rack that will require I/O
units to be mounted or removed during operation. Even if none of the I/O
Units on the CPU Rack will be removed or mounted during operation, an I/O
Remove Unit is needed if I/O substitution is to take place on an Expansion
I/O Rack connected to the CPU Rack.
19
Section 2-12
I/O Units
Special I/O Units, such as the A/D Conversion Input Unit or the High-speed
Counter Unit, cannot be removed or mounted during operation. In addition, if
Special I/O Units and standard I/O Units are mounted on the same Rack, none of
the Units on that Rack can be removed or mounted without affecting the other
Units. However, there are combinations with other I/O Units that allow substitution during PC operation. The following table explains the instances in which
standard I/O Units, when used in combination with other I/O Units, can be
removed or mounted during PC operation. The groups defined in the table are
used only in this section and do not apply to groups of similar nature in other
manuals.
Group
I/O Unit
Mounted to 3G2C5-BI082 and 3G2C5-BI083 Backplane
Group A
16-/32-/64-point I/O
When only Units from Group A are mounted to a Backplane the I/O Units can
be removed or mounted during PC operation.
Group B
PC Link Unit
Host Link Unit
When Units from Group B are mounted on the same Backplane as Units from
Group A, only the Units from Group A can be removed or mounted during PC
operation. However, this does not apply when using 3G2C5-BI083.
Group C
A/D Conversion Unit
D/A Conversion Unit
Remote I/O Master
Remote I/O Slave
Others
When Units from Group C are mounted on the same Backplane as Units from
Group A, neither Group a Units nor Group C Units can be removed or
mounted during PC operation.
! Caution
When removing or mounting an I/O Unit while the CPU is operating, be sure to
remove the terminal block from the I/O Unit first and then remove the I/O Unit
from the Backplane. If the entire I/O Unit is removed from the Backplane, output
signals are not cleanly disconnected, but may be sent to external devices, causing a sudden pulse to go the external device. This may in turn cause the device to
shudder. Also, when remounting the I/O Unit to the Backplane, fir st mount the
I/O unit and then the terminal Block to the I/O Unit.

Memory Packs
2-13 Memory Packs
The Memory Pack fits into the slot located on the right side of the CPU. Because
the Memory Pack is not provided with the PC upon delivery, a Memory Pack
must be selected and installed in the CPU. There are two Memory Packs available, either RAM or ROM, that can be used for both the C1000H and C2000H
Systems.
Note Mount a Memory Pack to the CPU on the left and another Memory Pack to the
CPU on the right. These Memory Packs must have the same specifications.
When using the RAM Pack, there must not be any difference in write-protect
switch settings for the left and right CPUs, otherwise a collation error will result
and the PC will not operate.
RAM Pack
Data can be randomly written to and read from the RAM Pack, making it possible
to enter your own program into the CPU. However, because this is not a fixed
program, the memory of the RAM Pack is erased when power is not supplied to
the CPU or when the RAM Pack is removed from the CPU without first being connected to a backup battery.
! Caution
1. When removing the RAM Pack from the CPU, be sure to connect the RAM
Pack to a backup battery before removing it from the CPU or the data will be
lost. Do not use the backup battery located in the compartment above the
Memory Unit Compartment. It is used to backup memory in the CPU.
2. Do not remove the battery in the CPU when the RAM Pack has been
removed from the CPU.
There is a write-protect switch and a write-protect indicator on the RAM Pack, as
shown in the following diagram. Setting the write-protect switch to OFF allows
data to be written to the RAM Pack. Use a peripheral device, such as a Programming Console, to write to the RAM Pack.

To write data to the RAM Pack, move the write-protect switch to the OFF position. After data is written to the RAM Pack, be sure to move the write-protect
switch to the ON position to protect the data from further alterations. If you try to
write data to the Memory Pack while the write-protect switch is in the ON position, the message DISABLED ROM will appear on the Programming Console.
Four models of RAM Packs are available, which vary in memory capacity: 8K,
16K, 24K, and 32K words. Refer to Appendix C Standard Models for model numbers.
23
Section 2-13
Memory Packs
ROM Pack
Data contained in the ROM Pack is stored on EPROM chips and cannot be
altered or erased during the CPU’s operation. The ROM Pack can accept four
EPROM chips, which can be programmed for your particular application with the
PROM Writer. The EPROM chip is mounted to the Memory Pack and the entire
pack is installed in the CPU. Once the data is written to the chip the data will not
be lost when the power to the PC is OFF.

SECTION 3
Assembly
When we speak of a PC, we usually think of it as a single object. But actually even the simplest PCs are usually composed of
several different devices. In fact a single PC can be physically spread throughout a building, but we still call it one PC.
In this section, we will start with a Backplane and use all the Units discussed in Section 2 to build a PC.

Mounting the Units
There is no single Unit that can be said to constitute a Rack PC. To build a Rack
PC, we start with a Backplane. The Backplane for the C1000H/C2000H is shown
below.
C1000H/C2000H Backplane
The Backplane is a simple device having two functions. The first is to provide
physical support for the Units to be mounted to it. The second is to provide the
connectors and electrical pathways necessary for connecting the Units
mounted to it.
The first device we will add to the Backplane is a Power Supply. The Power Supply fits into the rightmost position on the Backplane and provides electricity at the
voltages required by the other Units of the PC. It can also be used to power devices other than the PC if necessary.
Power Supply
The core of the PC is the CPU. The CPU contains the program consisting of the
series of steps necessary for the control task. The CPU fits into the position directly to the left of the Power Supply.
CPU
26
Section 3-1
Mounting the Units
Unlike the CPU of the Package-type PC, the CPU of the Rack PC has no I/O
points built in. So, in order to complete this kind of PC we need to mount one or
more I/O Units to the Backplane. Mount the I/O Units to the Backplane by pressing the I/O Unit firmly into position, making sure the connectors are properly
mated. Secure the Unit by tightening the mounting screws located on the top and
bottom of the Unit.
Mounting screws

bottom of the Unit

Make sure the connectors

The figure below shows one I/O Unit mounted directly to the left slot of the CPU
Rack.
I/O Unit
I/O Units are where the control connections are made from the PC to all the various input devices and output devices. As you can see from the figure, there is
still some space available on the right side of the I/O Unit. This space is for any
additional I/O Units that may be required.
27
Section 3-1
Mounting the Units
The figure above shows a total of six I/O Units mounted to the Backplane. Backplanes are available in different lengths, and can hold a different number of I/O
Units accordingly. Of course, not all I/O Units look exactly alike, but the ones in
the figure show their typical appearance. This configuration of Backplane,
Power Supply, CPU, and I/O Units is called a CPU Rack. This term refers to the
Backplane and all the Units mounted to it. However, if we want to include more
than six I/O Units in our configuration we can add an additional Backplane. First,
though, we have to mount an I/O Control Unit to the leftmost slot of the CPU
Rack.
I/O Control Unit
Now we can use a cable to connect the CPU Rack to another Backplane. This
Backplane has a Power Supply and I/O Units mounted to it, but it has no CPU of
its own. The additional Backplane must also have an I/O Interface Unit mounted
to its leftmost position. This configuration of additional Backplane, Power Supply, I/O Units, and I/O Interface Unit is called an Expansion I/O Rack.
CPU Rack
Expansion I/O Rack
I/O Interface Unit
The CPU Rack and Expansion I/O Rack shown above are connected by a cable.
Remember that this whole configuration is still referred to as one PC. It is possible to keep adding Expansion I/O Racks in this way until the maximum number of
I/O points for the system is reached. Each Expansion I/O Rack needs an I/O Interface Unit.
28
Section 3-2
C2000H Duplex System
3-2
C2000H Duplex System
The C2000H has a unique feature. The C2000H lets you build a PC that uses
two CPUs. This is called a Duplex System. Either CPU, which is mounted to the
CPU Rack, is capable of assuming the system function. One CPU controls the
system while the other CPU assumes a standby status. Consequently, if a failure
occurs in one of the CPUs, the other CPU can take over the system function,
preventing the entire system from halting, The figure below shows a Duplex System. Note that the CPU Rack is connected to the I/O Rack by two cables.
CPUs
CPU Rack
Duplex Unit
I/O Rack
While the Duplex System is in operation, one of the two CPUs has “active” status
and the other CPU has “standby” status. The active CPU executes the program
and controls the I/O Units while the standby CPU merely executes the program,
but does not control the I/O Units. The status of the CPUs can be determined by
setting the selector switch on the front panel of the Duplex Unit.
If an error occurs in the active CPU, making further operation impossible, the
standby CPU automatically becomes active and takes over operation. The
failed CPU can be repaired or replaced without having to shut down the entire
CPU.
Operating Mode
The operating mode is set through the active CPU. Once the operating mode of
the active CPU is set, the standby CPU is automatically set in same operating
mode as the active CPU.
Peripheral Devices
As mentioned, the operating mode can only be set through the active CPU. However, peripheral devices such as the Programming Console can be mounted to
the standby CPU to monitor operations.
Initial Settings
Take the following steps to prepare the Duplex System for operation.
1, 2, 3...
1. Be sure to install identical Memory Packs in both CPUs. Because one of the
CPUs in the Duplex System acts as a standby system, make sure that identical Memory Packs are installed in both CPUs. IF the active CPU can no
longer control the system, the standby CPU can take over the System using
an identical program.
ROM Packs When using ROM Packs, make sure that the same number and
same type of EPROM chips are mounted to both ROM Packs. In addition,
the same program must be written to both ROM Packs.
RAM Packs When using RAM Packs, make sure the Units have the same
memory capacity. Write the program to the RAM Unit installed in the active
CPU. The program written to the active CPU is automatically written to the
memory of the standby CPU when the Duplex System is put into operation.
29
Section 3-2
C2000H Duplex System
Note All information previously stored in the RAM Pack of the standby CPU
will be erased when a new program is written to the RAM Pack of the
active CPU.
2. Set the System Switch, located on the front panel of the Duplex Unit, to DPL
(Duplex System) or SPL (Simplex System). As shown below, the switch is
set to DPL to indicate a Duplex System.
CPU ON/OFF switches
Use these switches to supply power to
each of the CPUs. To operate the CPU,
move the corresponding switch to the
ON position. When replacing the CPU,
move the corresponding switch to the
OFF position, and remove the CPU
from the Rack. Note that power is not
supplied to the CPU whose corresponding switch is OFF.
ACTIVE SYSTEM
DPL (Duplex)
SPL (Simplex)
INITIAL SET
3. Next, select the active CPU by setting the Active Switch to RIGHT or LEFT.
In the example above, the right CPU is the active CPU.
4. To complete the initial settings, set both CPU ON/OFF selectors on the front
panel of the Duplex Unit to the ON position. If both CPU selectors are not in
the ON position, the Duplex System cannot operate.
When an Error Occurs in
the Duplex System
30
When the Duplex System is put into operation, both CPUs are in the ON position
and an active CPU, either the right CPU or the left CPU, is selected. A Duplex
System is a control system with two operable CPUs, an active CPU and a standby CPU, either of which can take over system operation at any time. However, if
an error occurs causing one of the CPUs to fail, the system automatically
changes to a Simplex System, regardless of the switch settings on the front panel of the Duplex Unit. For example, if an error occurs in the standby CPU causing
Section 3-2
C2000H Duplex System
it to be inoperable, it can no longer be a Duplex System and therefore automatically changes to a Simplex System, with only the active CPU controlling the system.
If there is an error that causes the active CPU to fail, the system again automatically changes to a Simplex System, switching control to the operable CPU (the
standby CPU). For example, the switches on the front panel of the Duplex Unit
indicate that the right CPU is active and controlling the I/O Units in a Duplex System. If the active CPU fails, the system changes from a Duplex System to a Simplex System and the operable standby CPU (in this example, the left CPU) takes
over the system operation and becomes the active CPU. The change from Duplex to Simplex and from active CPU to standby CPU takes place regardless of
the settings on the front panel of the Duplex Unit.
Switching from Duplex to
Simplex
If you are using a Duplex System but want to use only one CPU to write a program to the memory of the CPU or test the program in the CPU, switch the Duplex System to a Simplex System.
The flow chart below illustrates how the Duplex System can be changed to Simplex operation. The switches referred to in the flow chart are on the front panel of
the Duplex Unit. Assume that there is a Programming Console already mounted
to the active CPU.
Select the active CPU and set the ACTIVE switch to LEFT or RIGHT depending on which CPU is to be active.
Set the CPU ON/OFF switch which corresponds to the active CPU to the ON
position.

C2000H Simplex System
The C2000H Simplex System is a PC that operates with only one CPU. The operation of the Simplex System is quite similar to that of the C1000H, in that a
maximum of seven Expansion I/O Racks can be utilized to access a maximum of
2,048 I/O points.
One difference can be seen in the CPU Rack. Only six I/O Units can be mounted
to the CPU Rack of the C2000H Simplex System. Also, an I/O Remove Unit, a
feature unique to the C2000H Systems, can be mounted to the CPU and Expansion I/O Racks to allow on-line exchange.
3-4
Memory Packs
The CPU has a removable Memory Pack that stores the user program. Two
Memory Packs are available, in either RAM or ROM. You can write your own program into the RAM Pack or you can copy a program that has already been written to an EPROM chip and mount it in the ROM Pack. The EPROM Chip must be
mounted to the PROM Writer in order for the program to be written to it. Then the
EPROM Chip must be mounted to the ROM Pack.
Mounting the EPROM Chip
to the ROM Pack
Depending on the memory required for your application, choose either two chips
for 16K words or four chips for 32K words. Only one model of EPROM chip can
be used in the C1000H and C2000H PCs. Refer to Appendix B Specifications for
specifications of the EPROM chips.
Using the diagram and the table below as a reference, mount the EPROM chips
to the correct IC sockets.
Use a standard

Pack to a back-up battery before removing it from the Memory Compartment, or the data will be lost.
Note Do not use the back-up battery located in the compartment above the
Memory Unit. This battery is used to back-up the internal memory of
the CPU. If this battery is disconnected, the contents of the internal
memory will be lost.
4. Pull the white tabs of the Memory Pack up and out. The tabs push against
the guide rail provided for the Memory Pack and force the Memory Pack out
of the Memory Pack compartment.
Note When moving the C1000H or C2000H PCs, secure the Memory Pack
with holding brackets.

System Configurations
This section provides illustrations of assembled C1000H and C2000H Systems.
C1000H System
The following figure shows an assembled C1000H CPU Rack and one Expansion I/O Rack. When 7 Expansion I/O Racks are connected to a CPU Rack, a
maximum of 1,024 I/O points are available. When Remote I/O Units are used in
the system, the maximum number of I/O points available increases to 2,048.

C2000H Duplex System
The CPU Rack for the C2000H Duplex System, unlike the C1000H and the
C2000H Simplex Systems, has two CPUs and a Duplex Unit mounted to it. The
C2000H Duplex System is configured differently from the Simplex System, because it has an additional I/O Rack connected to the CPU Rack to accommodate
the I/O Units. Note that there are two connecting cables that connect the CPU
Rack to the I/O Rack. A maximum of seven Expansion I/O Racks can be connected to the I/O Rack, making 1,024 the maximum number of points available
when 16-point I/O Units are used. The number of I/O points is increased to 2,048
when the system is configured with 32-point I/O Units.

Where I/O Units Can be
Mounted
The table below summarizes the Units that can be used in the systems described in this manual.
Special I/O
Units
The number of Special I/O Units that can be used depends upon the number of points available and
the number of points the Special I/O Unit requires. Be sure to check the current capacity for each I/O
Unit and the CPU.
Host Link
Units
When using 3G2A5-LK103(-P)/LK203 Host Link Units, a maximum of two Rack-mounting Host Link
Units can be mounted to the CPU Rack or I/O Rack. An additional CPU-mounting Host Link Unit can
be mounted to the CPU, making the total number of Host Link Units three.
When using 3G2A5-LK101-(P)EV1/LK201-EV1 Host Link Units, only one Rack-mounting Host Link
Unit can be mounted to the CPU Rack or I/O Rack. An additional CPU-mounting Host Link Unit can
be mounted to the CPU, making the total number of Host Link Units two.
These Host Link Units cannot be mounted on Expansion I/O Rack.
If the SYSMAC Net Link Unit is mounted, either 3G2A5-LK103(-P) or 3G2A5-LK203 can be mounted
as Rack-mounting Host Link Unit. Both models cannot be mounted at the same time.
I/O Units
Standard I/O Units are available with 16, 32, or 64 points. These Units can be mounted to or removed
from the Rack if there is an I/O Remove Unit mounted to the Rack. Refer to Section 2 Description of
All Components for details.
Memory Packs
RAM or ROM Packs are available. The ROM Pack requires a separately available EPROM chip.
Install identical Memory Packs in both CPUs, if you are using a C2000H Duplex PC.
Remote I/O
Master Unit
Up to eight Remote I/O Master Units can be mounted to both the I/O Rack and the Expansion I/O
Racks. When the Remote I/O Unit is mounted to a Rack, a Rack number must be set so that the CPU
can identify the Remote I/O Unit. Mount the Remote I/O Slave Unit to the leftmost position (the I/O
Interface Unit position) on the Slave Rack. For details, refer to the C1000H/C2000H Operation
Manual.
The table below summarizes specific Units that can and cannot be mounted in
the CPU and Expansion Racks and the number that can be used in each PC. For

I/O Connections
Connect the I/O Devices to the I/O Units using AWG (cross-sectional area:
0.3 mm2) for 19-terminal terminal blocks and AWG 22 to lead wire (cross-sectional area: 0.3 to 0.75 mm2) for 10-terminal terminal blocks. The terminals have
screws with 3.5-mm diameter heads and self-raising pressure plates. Connect
the lead wires to the terminals as shown. Tighten the screws to a torque of 0.8
NSm.
Use ring crimp terminals for wiring. Do not connect bare stranded wires directly
to terminal blocks.
7 mm max.
Terminal Block
7 mm max.
The terminal block of an I/O Unit can be removed by loosening the mounting
screws. You do not have to remove the lead wires from the terminal block in order to remove it from an I/O Unit.
Note Putting I/O Lines and high-tension lines or power lines in the same duct or conduit may cause the I/O Lines to be affected by noise. This may cause a malfunction in the I/O Unit or may cause damage to the I/O Unit or I/O devices.
Terminal block mounting screws
Loosen the terminal block mounting screws to remove
the terminal block from the I/O Unit. Make sure the
mounting screws on the terminal block are tightened after wiring is complete, and the terminal block is remounted to the I/O Unit.
Note When a Triac Output Unit is used to drive a low-current load, the load may not
turn completely OFF due to a leakage current. To compensate for the leakage
current, connect a bleeder resistor in parallel with the load.

Wiring Examples
The following are examples of how to connect I/O devices to I/O Units. During
wiring, work slowly and carefully. If an input device is connected to an Output

Section 5-2
Mounting Requirements
5-1
Cooling
There are two points to consider in order to ensure that the PC does not overheat. The first is the clearance between the Racks, and the second is installation
of a cooling fan.
Clearance Between Racks
The Racks need to have sufficient room between each other to allow for I/O wiring, and additional room to ensure that the I/O wiring does not hamper cooling.
However, the Racks must be mounted so that the length of the connecting cable
does not exceed 2 m, and the total length of the Connecting Cables between all
Racks does not exceed 12 m. For details about cable lengths, refer to Appendix
C Standard Models. As a general rule, about 70 to 120 mm should be left between any two Racks (50 to 100 mm should be left between any two Racks in the
Duplex System).
Cooling Fan
A cooling fan is not always necessary, but may be needed in some installations.
Try to avoid mounting the PC in a warm area, or over a source of heat. A cooling
fan is needed if the ambient temperature may become higher than that specified
(refer to Appendix B Specifications). If the PC is mounted in an enclosure install
a cooling fan, as shown in the following diagram, to maintain the ambient temperature within specifications.
Fan
PC
Louver
5-2
Mounting Requirements
The PC consists of from one to eight Racks, or from one to nine Racks if you are
using the C2000H Duplex System. Each Rack must be mounted vertically, that
is with the printing on the front panels oriented as it would normally read. The
Racks should be mounted one above the other with the CPU Rack uppermost.
The PC may be directly mounted to any sturdy support meeting the environmental specifications (refer to Appendix B Specifications).
The duct work shown in the following diagram is not used for mounting the
Racks. Although optional, the duct work can be used to house the wires from the
I/O Units that run along the sides of the Racks, keeping the wires from becoming
entangled with other machines. The figures illustrate the correct way to mount
the Racks.

Preventing Noise
In order to prevent noise from interfering with the operation of the PC, use AWG
14 twisted-pair cables (cross-sectional area: 2 mm2 min.). Avoid mounting the
PC close to high-power equipment, and make sure the point of installation is at
least 200 mm away from power cables as shown below.
Power lines
200 mm min.
PC

Whenever possible, use wiring conduit to hold the I/O wiring. Standard wiring
conduit should be used, and it should be long enough to completely contain the
I/O wiring and keep it separated from other cables.
51
SECTION 6
Power Considerations
Use a commercially available 100 to 120 VAC, 200 to 240 VAC, or 24 VDC power source, according to the model of PC you
are using (refer to Appendix B Specifications). Expansion I/O Racks, if used, must also be connected to the power source. If
possible, use independent power sources for the PC, input devices, and output devices. All Racks of the PC may be connected
to one power source.
53
Section 6
Power Considerations
Grounding
The Line Ground (LG) terminal is a noise-filtered neutral terminal that does not
normally require grounding. If electrical noise is a problem, however, this terminal should be connected to the Ground (GR) terminal.
To avoid electrical shock, attach a grounded (earth ground) AWG 14 wire (crosssectional area: 2 mm2 min.) to the GR terminal. The resistance to ground must
be less than 100 W. Do not use a wire longer than 20 m. Care must be taken,
because ground resistance is affected by environmental conditions such as soil
composition, water content, time of year, and the length of time since the wire
was laid underground.
PC operation may be adversely affected if the ground wire is shared with other
equipment, or if the ground wire is attached to the metal structure of a building.
When using an Expansion I/O Rack, the Rack must also be grounded to the GR
terminal. The same ground can be used for all connections.
Power Failure
A sequential circuit is built into the PC to handle power interruptions. This circuit
prevents malfunctions due to momentary power loss or voltage drops. A timing
diagram for the operation of this circuit is shown below.

The PC ignores all momentary power failures if the interruption lasts no longer
than 10 ms. If the interruption lasts between 10 and 25 ms, the interruption may
or may not be detected. If the supply voltage drops below 85% of the rated voltage for longer that 25 ms (less for the DC Power Supply), the PC will stop operating and the external outputs will be automatically turned OFF. Operation is resumed automatically when the voltage is restored to more than 85% of the rated
value.

SECTION 7
Safety Considerations
There are certain safety requirements to be considered when installing the PC. Some of these, such as the emergency stop
circuit (refer to Power Supply), are part of the initial wiring. The considerations described below should be kept in mind when
operating the PC and when connecting I/O devices to the PC.
59
Section 7
Safety Considerations
Interlock Circuits
When the PC controls an operation such as the clockwise and counterclockwise
operation of a motor, provide an external interlock such as the one shown below
to prevent both the forward and reverse outputs from turning ON at the same
time.
Interlock circuit
00501
MC2
MC1 Motor clockwise
PC
00502
MC1
MC2 Motor counterclockwise
This circuit prevents outputs MC1 and MC2 from both being ON at the same
time. Even if the PC is programmed improperly or malfunctions, the motor is protected.
Power Supply Output
The 24 VDC output of the CPU and Expansion I/O Power Supply may be used to
power other devices. The output current of these supplies is limited to 0.3 A. A
separate Power Supply must be provided if the devices being powered require a
higher current.
Input Leakage Current
When two-wire sensors, such as photoelectric sensors, proximity sensors or
limit switches with LEDs are connected to the PC as input devices, the input bit
may be turned ON erroneously by leakage current. In order to prevent this, connect a bleeder resistor across the input as shown below.
Input
power
supply
Bleeder

R

Sensor
If the leakage current is less than 1.3 mA, there should be no problem. If the leakage current is greater than 1.3 mA, determine the value and rating for the
bleeder resistor using the following formulas.

Safety Considerations

Where
Eon = ON voltage of the load
I = leakage current in mA
R = bleeder resistance
Output Surge Current
When connecting a transistor or triac Output Unit to an output device having a
high surge current (such as an incandescent lamp), care must be taken to avoid
damage to the Output Unit. The transistor and triac Output Units are capable of
withstanding a surge current of ten times the rated current. If the surge current
for a particular device exceeds this amount, use the circuit shown below to protect the Output Unit.
L
OUT
+
R
COM
Another way of protecting the Output Unit lets the load draw a small current
(about one third the rated current) while the output is OFF, significantly reducing
the surge current. This circuit (shown below) not only reduces the surge current,
but also reduces the voltage across the load at the same time.
R
OUT
L
+
COM
Transistor Output Residual
Voltage
When connecting TTL circuits to transistor Output Units, connect a pull-up resistor and a CMOS IC between the two. This is because of the residual voltage left
on the transistor output after the output turns OFF.
61
Section 7
Safety Considerations
Inductive Load Surge
Suppressor
When an inductive load is connected to an I/O Unit, connect a surge suppressor
or diode in parallel with the load as shown in the following diagram. This is so that
the back electromagnetic field generated by the load will be absorbed.
Resistor: 50 W
Capacitor: 0.47 F
Voltage: 200 V
Diode:
Must withstand voltages of more
than three times the load voltage and an average current of 1 A

Electrical Noise
62
Take appropriate measures when any electrical device likely to produce noise is
connected to the PC as a load. Devices generating noise of more than 1,200 V
(such as electromagnetic relays and valves) require noise suppression. For
noise sources running on AC power, connect a diode in parallel with the coil of
each device.
When mounting a CPU Rack and an Expansion I/O Rack together on a mounting
plate, provide a solid ground to the mounting plate. The mounting plate must be
plated with a highly conductive surface in order to ensure noise immunity.
Appendix A

DC Input Unit 3G2A5-ID212
In the case where a large number of bits must be controlled, an ID212 DC Input Unit can simplify wiring by controlling up to 64 bits through only 16 points. Using digital switches or a specially wired keyboard, different combinations of points can access specific bits and words. Two examples of connections using digital switches or a keyboard are given.
Connection Example 1 (Keyboard)
The table below shows how the ID212 DC Input Unit can be wired using a specially wired keyboard. For example, if
A on the keyboard is pressed, the combination of DATA0 and STB9 turn ON bit 00, word n. Similarly, the combination of DATA 7 and STB7 turn ON bit 15, word n+3. The value of word n depends on where the Unit is mounted on
the Rack. For details, refer to the C1000H/C2000H Operation Manual.

Note Because the DC Input Unit is operated on an extremely small current, make sure there is adequate distance
between the DC Input Unit wires and high-tension equipment or power lines. If this cannot be avoided, use
shielded cables when wiring the DC Input Unit. Be sure to keep the total length of the wires less than 10 m.
Connection Example 2 (Digital Switches)
This example shows how the ID212 DC Input Unit can be wired using digital switches. Just as the keys on the
keyboard can access different combinations of words and bits, the digital switches can access different combinations of words and bits. For example, the combination of switch no. 1 and point 00 access word bit 00, word n.

Special Considerations for C500-OA225
The maximum current value allowed per point differs depending on the ambient temperature and the number of
points per common that are ON simultaneously. The graph below shows the relationship between the allowable
current per point and the number of points ON per common. Be sure not to exceed the values depicted in the
graph.

The graph below shows the value of an surge current and the time it takes the current to level to a steady stream of
current (current-carrying time). The curved line in the graph represents the maximum value of surge current at
which the Unit can operate properly. It is suggested that when opening and closing a load with a large surge current, to keep the value of the surge current to half the value shown the graph (within the shaded area).

DC Output Unit 3G2A5-OD211
By using the OD211 DC Output Unit, a large number of bits can be controlled through only 16 points. Just like the
ID211 DC Input Unit, different combinations of points can access bits and words to control different outputs. Using
this type of Unit can simplify wiring when many bits must be controlled. Up to 64 bits can be accessed.
Because the output data is positive logic, the terminal output goes high when the output data is logical 1. The
strobe output is negative logic, so when a signal is output, the corresponding terminal goes low. Use positive logic
output devices for the load of this Unit. The strobe output is cyclically and automatically output.

Note Because the DC Input Unit is operated on an extremely small current, make sure there is adequate distance
between the DC Input Unit wires and high-tension equipment or power lines. If this cannot be avoided, use
shielded cables when wiring the DC Input Unit. Be sure to keep the total length of the wires less than 10 m.

Note Power is supplied to the Dummy I/O Unit from the 24 VDC output terminal of the Power Supply, which is
mounted on the same Rack as the Dummy I/O Unit. Be sure to supply power to the Dummy I/O Unit before
supplying power to the CPU. If power is supplied to the Dummy I/O Unit after power is supplied to the CPU,
the Dummy I/O Unit is assumed to have only 16 I/O points, and may result in an I/O Verification Error or an

I/O Connecting Cables
Use either a vertical or horizontal I/O Connecting Cable to connect the CPU Rack to an Expansion I/O Backplane
or to connect an Expansion I/O Backplane to additional Expansion I/O Backplane. If you are using the C2000H
Duplex System, use two I/O Connecting Cables to connect the CPU Rack to the I/O Rack.
Fasten the connectors with the locks provided on the connectors to secure the connection between the cable connector and the connector on the Backplane. If the connectors are not properly connected during CPU operation,
errors such as I/O BUS error or I/O SETTING error will occur.
106

Specifications
The length of the connecting cable depends on the distance between the two Racks to be connected. The length of
the cable should be approximately 20 cm longer than the distance between the two Racks.

Glossary
Backplane
A base to which Units are mounted to form a Rack. Backplanes provide a series
of connectors for these Units along with wiring to connect them to the CPU and
Power Supply. Backplanes also provide connectors used to connect them to
other Backplanes. In some Systems, different Backplanes are used for different
Racks; in other Systems, Racks differ only by the Units mounted to them.
back-up

the LR area is designed to hold common data in a PC Link System.
data link
Allows for the connection of up to 32 PCs in a Net Link System where each is
contributing information to a common memory area. Data links may be established in the LR and/or DM memory areas.
distributed control
An automation concept in which control of each portion of an automated system
is located near the devices actually being controlled, i.e., control is decentralized
and “distributed” over the system. Distributed control is a concept basic to PC
Systems.
Duplex System
A C2000H PC that operates using two CPUs mounted to the CPU Rack. One
CPU controls the system while the other CPU assumes a standby status.
Duplex Unit
A Unit in the C2000H Duplex System that switches control between the two
CPUs.
EEPROM
[E(lectrically) E(rasable) P(rogrammable) R(ead) O(nly) M(emory)] A type of
ROM in which stored data can be erased and reprogrammed. This is accomplished using a special control lead connected to the EEPROM chip and can be
done without having to remove the EEPROM chip from the device in which it is
mounted.
117
Glossary
EPROM
[E(rasable) P(rogrammable) R(ead) O(nly) M(emory)] A type of ROM in which
stored data can be erased, by ultraviolet light or other means, and
reprogrammed.
Expansion I/O Unit
An I/O Unit for a Package-type PC that provides more I/O points to the PC.
factory computer
A general-purpose computer, usually quite similar to a business computer, that
is used in automated factory control.
High-speed Counter
A Special I/O Unit. A High Speed Counter Unit counts independently of the PC’s
cycle time. This allows counting of very short, fast signals.
host computer
A computer that is used to transfer data to or receive data from a PC in a Host
Link system. The host computer is used for data management and overall system control. Host computers are generally small personal or business computers.
IBM PC/XT or AT, or
compatibles
A computer that has similar architecture to, and is logically compatible with an
IBM PC/XT computer; and that can run software designed for that computer.
I/O Expansion Backplane
A Backplane used to create an Expansion I/O Rack.
I/O Control Unit
A Unit mounted to the CPU Rack in certain PCs to monitor and control I/O points
on Expansion I/O Units.
I/O devices
The devices which are connected to the terminals on I/O Units, Special I/O Units,
or Intelligent I/O Units. I/O devices may be part of the Control System if they
function to help control other devices, or they may be part of the controlled system if they interact directly with it.
I/O Expansion Rack
Part of a Rack PC, an Expansion I/O Rack is connected to a CPU Rack to increase the number of slots available for mounting Units.
I/O Interface Unit
A Unit mounted to an Expansion I/O Rack in certain PCs to interface the Expansion I/O Rack to the CPU Rack. An I/O Interface Unit is needed when the first
Expansion I/O Rack is connected to the CPU Rack via a Connecting Cable.
Each Expansion I/O Rack needs an I/O Interface Unit.
I/O point
The place at which an input signal enters the PC System or an output signal
leaves the PC System. In physical terms, an I/O point corresponds to terminals
or connector pins on a Unit; in terms of programming, an I/O point corresponds
to an I/O bit in the IR area.
I/O Remove Unit
Unique to C2000H Systems, this Unit allows standard I/O Units to be mounted to
or removed from the Backplane during PC operation.
I/O Unit
The most basic type of Unit mounted to a Backplane. I/O Units include Input
Units and Output Units, each of which is available in a range of specifications.
I/O Units do not include Special I/O Units, Link Units, etc.
PC
An acronym for Programmable Controller.
PC Link Unit
A Unit used to connect two or more PCs together so that they can exchange data
through their LR areas.
Position Control Unit
A Special I/O Unit used to control the operation of positioning devices such as
Servomotors.
118
Glossary
Power Supply
A Unit that mounts to a Backplane in a Rack PC. It provides power at the voltage
required by the other Units on the Rack.
Programmable Controller
A small, computer-like device that can control peripheral equipment, such as an
electric door or quality control devices, based on programming and peripheral
input devices. Any process that can be controlled using electrical signals can be
controlled by a PC. PCs can be used independently or networked together into a
system to control more complex operations.
PROM
[P(rogrammable) R(ead) O(nly) M(emory)] A type of ROM into which the program or data may be written after manufacture, by a customer, but which is fixed
from that time on.
PROM Writer
A PROM Writer is a device used to write data to ROM, PROM, and EPROM storage chips.
Rack
An assembly that forms a functional unit in a Rack PC System. A Rack consists
of a Backplane and the Units mounted to it. These Units include the Power Supply, CPU, and I/O Units. Racks include CPU Racks, Expansion I/O Racks, and
I/O Racks. The CPU Rack is the Rack with the CPU mounted to it. An Expansion
I/O Rack is an additional Rack that holds extra I/O Units. An I/O Rack is used in
the C2000H Duplex System, because there is no room for any I/O Units on the
CPU Rack in this System.
Rack PC
A PC that is composed of Units mounted to one or more Racks. This configuration is the most flexible, and most large PCs are Rack PCs. A Rack PC is the
opposite of a Package-type PC, which has all of the basic I/O, storage, and control functions built into a single package.
RAM
[R(andom) A(ccess) M(emory)] RAM will not retain data when power is disconnected. Therefore data should not be stored in RAM.
Remote I/O Unit
A Unit that extends the distance an Expansion I/O Rack can be from the CPU.
ROM
[R(ead) O(nly) M(emory)] A type of digital storage that cannot be written to. A
ROM chip is manufactured with its program or data already stored in it, and it can
never be changed. However, the program or data can be read as many times as
desired.
Simplex System
A C2000H PC that operates using one CPU mounted to the CPU Rack.
Space Unit
A Unit mounted to the I/O Backplane of a C2000H Duplex System that simply fills
the space between the I/O Expansion Power Supply and the rightmost Unit
mounted on the Rack.
Special I/O Unit
A dedicated Unit that is designed for a specific purpose. Special I/O Units include Position Control Units, High-Speed Counters, Analog I/O Units, etc.
system configuration
The arrangement in which Units in a System are connected. This term refers to
the conceptual arrangement and wiring together of all the devices needed to
comprise the System. In OMRON terminology, system configuration is used to
describe the arrangement and connection of the Units comprising a Control System that includes one or more PCs.
Unit
In OMRON PC terminology, the word Unit is capitalized to indicate any product
sold for a PC System. though most of the names of these products end with the
word Unit, not all do, e.g., a Remote Terminal is referred to in a collective sense
as a Unit. Context generally makes any limitations of this word clear.
