     1--1 Section 1--2 Introduction Analog I/O Modules are used to interface the digital operation of the PLC with analog I/O field devices. Analog Input Modules convert analog signal from input devices to digital PLC data. Analog Output Modules convert digital PLC data to analog signals for output devices. 1--2 Basic Configuration This diagram shows some of the possible field devices for the Analog I/O Modules. Any I/O device may be used as long as its voltage/current requirements fall within the specified ranges (see Appendix B). The I/O device connected to the Analog I/O Module will often serve as an interface for another device, e.g., a preamplifier may interface a pressure gauge to increase the signal level to Analog Input Module requirements; a regulator may interface a heating system to control temperature.

The first diagram shows a temperature regulating system and the second shows a servomotor positioning system. Analog Input Module PLC Transducer Temperature sensing element Valve controller Output Module fuel Sensor M Platform Servo controller Analog Output Module Servo motor Encoder Locating pulse High-speed Counter Module 1--4 Allocated Words Each Analog I/O Module is allocated either two or four words. This section specifies only the actual number of words allocated to the Modules; use of these words is dealt with in Section 4 Operation. The first word allocated to the Module is designated as “n” in this manual. Remaining words, which are always consecutive, are designated as n+1, n+2, etc. Refer to you PLC’s Operation Manual for details on how words are allocated to Modules.     1--4--1 Section 1--4 AD001 through AD005 Analog Input Modules Each of these Analog Input Modules is allocated two words, one for each analog input point. Word n is for point 1, and word n+1 is for point 2. Each of these words contains the decimal-converted value for the analog input point. 1--4--2 AD006 and AD007 Analog Input Modules Each of these Analog Input Modules is allocated four words, one for each analog input point. Word n is for point 1, word n+1 is for point 2, word n+2 is for point 3, and word n+3 is for point 4. Each of these words contains the decimal-converted value for the analog input point. 1--4--3 AD101 Analog Input Modules Each of these Analog Input Modules is allocated either two or four words, depending on the switch settings. The operation of the Module is completely different depending on this switch setting. Refer to later sections of this manual for details. 1--4--4 DA001 through DA005 Analog Output Modules Each of these Analog Output Modules is allocated two words, one for each analog output point. Word n is for point 1; word n+1 is for point 2. Each of these words contains the digital-converted value for the analog output point. 1--4--5 DA101 Analog Output Modules Each of these Analog Output Modules is allocated four words, one for each analog output point. Word n is for point 1, word n+1 is for point 2, word n+2 is for point 3, and word n+3 is for point 4. Each of these words contains the digital-converted value for the analog output point.  SECTION 2 Components and Switch Settings This section describes the switch settings for the AD101 Analog Input Module and the DA101 Analog Output Module. There are no switch settings required on the other Analog I/O Modules. 2--1 AD101 Analog Input Modules . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2--2 DA101 Analog Output Modules . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 9      2--1 Section 2--1 AD101 Analog Input Modules There are two settings necessary for this Module: the operation mode and the input ranges (offset and gain) for each input point Operation Mode Select either two-word or four-word operation. If you select two-word operation, data is transferred between the Analog Input Module and PLC using the I/O READ and I/O WRITE instructions, WRIT(87) and READ(88). If you select four-word operation, data is transferred between the Analog Input Module and PLC via the MOVE instruction, MOV(21). Use of WRIT(87) and READ(88) will simplify programming and shorten the time required to access analog input data. The switch for this setting is on the back of the Module and will not be accessible while the Module is mounted to a Rack. Be sure to set this switch before mounting the Module to the PLC. The setting of the switch is read when the PLC power is turned ON. Caution Only the following C120 and C500 CPUs are equipped with WRIT(87) and READ(88), which are required for two-word operation: 3G2C4-SC023-E and 3G2C3-CPU11-EV1 With all other C120 and C500 CPUs, you must use four-word operation. These instructions are supported by all C1000H and C2000H CPUs. Two-word operation is not possible if the Analog I/O Module is mounted to a Slave Rack in a Remote I/O System, regardless of the CPU. Four-word operation Two-word operation Back of Module Input Ranges Each input point is set with an offset (minimum) of 1 V (4 mA) and a gain (maximum) of 5 V ( 20 mA) at the factory. Use the following procedure to change these settings if necessary. The offset and gain can be set to anywhere between 0 and 10 V (0 and 20 mA) as long as the gain is greater than the offset. (Refer to Section 3 Operation for details on AD conversion.) Caution If an offset is set below 0 V (0 mA), the binary-converted value will be locked at 000hex; if a gain is set above 10 V (20 mA), the binary-converted value will be locked at FFFhex for voltage inputs, but not for current inputs.      Section 2--1 1, 2, 3... 1. First set up a power source and meter. For voltage inputs, you will need a 0 to 10 VDC supply and a DC voltmeter. For current input, you will need a 0 to 20 mA DC supply and a DC ammeter. Mount the Module to the PLC and connect the power source and meter. Voltage and current specifications can be set independently for each input point. The following examples illustrate how to wire the input points Wiring when input 1 is set at 0 to 10 V: Wiring when input 5 is set at 0 to 20 mA: AD101 AD101 15 0 0 + 16 Short terminals 0 to 10 VDC 1 17 16 and 17. 2 2 18 2. 0 to 20 mA DC Turn the PLC power supply and confirm that power is being supplied to the PLC. SW 1 (DIP switch) Use to designate the input point. SW 2 (toggle switch) Use to read in the desired values. 3. Remove the front panel of the Module with flat-blade screwdriver. Pins 1 through 8 on SW 1 represent input points 1 through 8 respectively. Turn ON the pin for the input point to be set and make sure all the other pins are OFF. First we will set input point 1. OFF 4. ON The offset is the lowest voltage or current that will be input. The Module will convert this value to 000 hexadecimal. Apply the desired offset to the terminals of input point 1. Flip SW 2 down to read in as O V or mA the current or voltage currently being applied to the input terminals. This input value will be stored as the offset, i.e., as zero.      Section 2--1 SW 1 Flip SW 2 down. SW 2 5. The gain is the highest voltage or current that will be input. The Module will convert this value to FFF hexadecimal. Apply the desired gain) to the terminals of input point 1. Flip SW 2 to down to read in as10 V or 20 mA current or voltage currently being applied to the input terminals. The input value will be stored as the gain, i.e., as 10 V or 20 mA. SW 1 Flip SW 2 up. SW 2 6.  Continue on in this way to set the offset and gain for input points 2 through 8. Make sure you turn OFF each pin of SW 1 before you turn ON the next pin. Never allow more than one pin of SW 1 to be ON simultaneously. After you are finished setting all the input points, re-attach the front panel to the Module.      2--2 Section 2--2 DA101 Analog Output Modules The output range must be set for each input point using the DIP switches on the back of the Module. Each input point is set to 1 to 5 V at the factory, but double check the settings before use. Be sure to set these switches before mounting the Module, as they will not be accessible while the Module is mounted. DIP switch Port 1 SW1 2 SW1 3 SW2 SW2 4 Pin Output range 0 to 10 V 1 to 5 V 4 to 20 mA 1 OFF ON ON 2 OFF ON ON 3 OFF OFF ON 4 ON OFF OFF 5 OFF ON ON 6 OFF ON ON 7 OFF OFF ON 8 ON OFF OFF 1 OFF ON ON 2 OFF ON ON 3 OFF OFF ON 4 ON OFF OFF 5 OFF ON ON 6 OFF ON ON 7 OFF OFF ON 8 ON OFF OFF Set the pins to the appropriate positions for the output range you are going to use.

 Section 3--1        3--1--2 Section 3--1 Wiring Use shielded twisted-pair cable for external connections. Connect the positive and negative terminals of any unused input points to the shield terminal. Use separate power supplies for input points 1 and 2 whenever possible. When using separate power supplies, always connect the negative input terminal to the shield line; failure to do so will produce several percent of error in the converted data. Incorrect wiring will produce inaccuracy in converted data. Use the proper wiring diagram and wire with care. Voltage Inputs VOLTAGE ONLY AD001 AD002 AD003 AD004 AD005

This data can be used directly in binary form or converted to BCD for further use.

Line (1) in the following figures shows the factory settings, 1 to 5 V (4 to 20 mA). This means that an input of 1 V (4 mA) will be converted to 000hex and an input of 5 V (20 mA) will be converted to FFFhex. The maximum ranges, 0 to 10 V (0 to 20 mA), are shown by line (2) in the figures. The offset and gain for any input point can be set anywhere within these ranges as long as the gain is greater than the offset: the offset value is always converted to 000hex, and the gain is always converted to FFFhex.      Section 4--3 The relationships between the input analog values and the converted binary values are shown below. Binary values are given in their hexadecimal equivalents.

Some of these steps have already been described in this manual. Start Programming Setup Set operating mode. Select either two-word or four-word operation. See Section 2 Components and Switch Settings. Set input ranges. Mount the Module to the Rack, and then set the input range for each input point, See Section 2 Components and Switch Settings. Wiring connections Connect input signal wiring. See Section 4 Installation. Word allocation Programming Allocate I/O and DM areas. See Section 4 Operation. Write the PLC program. Operate 4--3--4 Two-word Operation In two-word operation, there are two types of data transfer that occurs between the Analog Input Module and the PLC. One of these uses the normal      Section 4--3 I/O refresh period to transfer flag and control bit status (see IR Bit Allocations below) between the Analog Input Module and the IR words allocated to the Module. Here, the output word (IR n) is used to designate when peak value for input points are to be read or reset and the input word (IR n+1) is used to confirm data validity and to check when peak values are being read. The other form of data transfer is used to write parameters (e.g., offsets and gains) directly to the Analog Input Module or to read data (i.e., binary-converted analog values or peak values) directly from the Module. In this case the input and output words are used as the operands for the I/O WRITE and I/O READ instructions, WRIT(87) and READ(88). The data being read or written is stored at consecutive words beginning at a word designated as another operand. The general forms of these instructions are shown below. Refer to your PLC’s Operation Manual for details. I/O READ Instruction I/O WRITE Instruction READ (88) WRIT (87) Number of words transferred Specify IR n+1 Beginning destination word Number of words transferred Beginning source word Specify IR n Communications The following diagram illustrated communications between the AD101 Analog Input Module and the PLC during two-word operation. The I/O READ and I/O WRITE instructions are used to directly read and write data. Refer to the next page for details on IR n and IR n+1. READ(88) IR n+1 (input word) WRIT(87) AD101 Analog Input Module IR n (output word) PL C I/O refresh IR n+1 I/O refresh IR n IR Bit Allocations The following bits are used to control data transfer between the Analog Input Module and the PLC as explained below the table. The first three bits in each word are system handshaking flags, bit 03 of n+1 is used to confirm data,      Section 4--3 and the other bits are used to control and monitor reading of peak input values. Bit Ouput word: IR n Input word: IR n+1 00 (PC Busy Flag) (A/D Busy Flag) 01 (PC Write Finished Flag) (A/D Read Finish Flag) 02 (PC Read Finished Flag) (A/D Write Finish Flag) 03 Not used. Unconfirmed Data Flag 04 to 06 Not used. Not used. 07 Peak Reset Bit Not used. 08 Peak Read Bit 0 Peak Flag 0 09 Peak Read Bit 1 Peak Flag 1 10 Peak Read Bit 2 Peak Flag 2 11 Peak Read Bit 3 Peak Flag 3 12 Peak Read Bit 4 Peak Flag 4 13 Peak Read Bit 5 Peak Flag 5 14 Peak Read Bit 6 Peak Flag 6 15 Peak Read Bit 7 Peak Flag 7 Handshaking Flags Bits 00 through 02 of both the input and output words are system handshaking flags and cannot be used in programming. The status of these bits determines whether or not the I/O READ and I/O WRITE instructions will be executed as desired (see Reading Data and Writing Data below). Unconfirmed Data Flag This bit turns ON when data has not been confirmed (for example, when the power has just been turned on). Be sure this flag is OFF before reading data. Peak Reset Bit This bit is turned ON with one or more of the Peak Read Bits to reset the peak values of the input points designated by the Peak Read Bit. Peak Read Bits If the Peak Reset Bit is OFF, these bits are turned ON to read the peak values. The peak value for each ON bit will be read in the next time READ(88) is executed for the input word. If the Peak Read Bit is turned ON for an input point, the data read with the next READ(88) will be the peak value; if the Peak Read Bit is turned OFF for a point, the data read with the next READ(88) will be the normal input value. Here, however, “the next READ(88)” is the next one following the next I/O refresh period. The Peak Flags can be used to check to see whether peak values have been reached. The Peak Read Bits are also used with the Peak Reset Bit to reset the peak values. Peak Flags The Peak Flags turn ON to indicate that the input value for the input point has reached a peak value. input points for which peak values have been read instead of normal input values. Writing Data WRIT(87) is used to transfer operating parameter directly to the Analog I/O Module and is executed only when both the A/D Busy Flag (IR n+1, bit 00) and A/D Read Finished Flag (IR n+1, bit 01) are OFF. If either of these flags is ON when WRIT(87) is reached in the program, WRIT(87) will be executed as NOP. After WRIT(87) has been executed, the PC Write Finished Flag (IR n, bit 01) will turn ON for one scan and the Equals flag ( SR 6306 or SR 25506) will turn ON.      Data Writing Area Section 4--3 WRIT(87), is used to transfer a maximum of 26 words of data to the Analog Input Module. The first word, m, is specified by the user and written as the beginning source word of WRIT(87). All consecutive words must be in the same data area (DM m through DM m+25). The first two words are used to specify which points will be used and which points the mean and scaling functions will be used for. If the mean or scaling values are not required for an input point, no data need be provided, i.e., you need to transfer only the data that is actually required for operation as specified in the first two words. If not all of the data is required, fewer words will need to be transferred.

If one of these is not needed for a point, move all other parameters up one word to replace it. For example, if a mean value is not required for input point 3 but is required for points 1, 2, and 4, the mean value for point 4 would be placed in DM m+ 04 instead of DM m+5. Point Specification  If a point is to be used, turn the corresponding bit ON. If a point is not to be used, turn the corresponding bit OFF.     DM m Section 4--3 07 06 05 04 03 02 01 00 Input point 1 to Input point 8 Mean Value Specification If mean for an input point is to be used, turn the corresponding bit ON. If mean is not to be used, turn the corresponding bit OFF. DM m 15 14 13 12 11 10 09 08 Input point 1 to Input point 8 Specify the sampling count (2 through 9999) for the mean value. Enter data for each point specified for the mean function. Data must be specified in BCD. The actual words where data will need to be stored will depend on the actual data required. If a large count is set, the conversion time may exceed the10-ms-per-point conversion time by 1 or 2 ms. DM m+2 15 to 00 to to DM m+9 Scaling Input point 1 15 to 00 Input point 8 If scaling is to be used for an input point, turn the corresponding bit ON. If scaling is not to be used, turn the corresponding bit OFF. DM m 15 14 13 12 11 10 09 08 Input point 1 to Input point 8 Enter the offset and gain for each point for which the scaling function has been designated. The offset is the value that is to correspond to 000hex. The gain is the value corresponding to FFFhex. The offset and gain must be set in BCD and must be in the range 0 through 9999. The gain must be greater than the offset. DM m+10 15 to 00 DM m 11 15 to 00 Offset Input point 1 Gain to to DM m 24 DM m 25 15 15 to to 00 00 Offset Input point 8 Gain      Section 4--3 Reading Data READ(88) will be executed when the A/D Busy Flag (IR n+1, bit 00) is OFF and the A/D Write Finished Flag (IR n+1, bit 02) is ON. If the A/D Busy Flag is ON or the A/D Write Finished Flag is OFF, READ(88) will not be executed. The data transferred for READ(88) depends on the status of the Peak Read Bits, i.e., if the Peak Read Bit for an input is ON, the peak value will be transferred; if the Peak Read Bit is OFF, the normal binary-converted value will be transferred. The Peak Flags can be used to confirm what data has been transferred. The last word transferred always contains the Disconnection Flags. Data Reading Area READ(88) is used to transfer a maximum of 9 words of data beginning from DM l. The first word, l, is specified by the user and written as the beginning destination word of READ(88). You can select any area of DM as long as the end of the area is not exceeded (DM l through DM l+8). DM word Bit 15 14 13 12 11 10 DM l Input point 1 converted data DM l+1 Input point 2 converted data DM l+2 Input point 3 converted data DM l+3 Input point 4 converted data DM l+4 Input point 5 converted data DM l+5 Input point 6 converted data DM l+6 Input point 7 converted data DM l+7 Input point 8 converted data DM l+8 0 9 8 0 7 6 5 4 3 2 1 0 Disconnection Flags Note Do not allocate the same area for both writing and reading data. Input Point Converted Data DM l+2 A/D converted data is written to the specified words. When scaling is used, data is in 4-bit BCD (bits 00 to 15). When scaling is not used, data is in 3-bit hexadecimal (bits 00 to 11). 15 to 00 to DM l+7 Disconnection Flags Input point 1 to 15 to 00 Input point 8 When an input line disconnection is detected, the flag assigned to the input point will turn ON. The offset value must be at least 1 V (1 mA) for these flags to work.

IR n+1 is used to control data transfer and IR n+3 is used to monitor data transfer. To write data, move the desired data to IR n and then set the proper control bits to designate what data has been set. The data will be read in at the next I/O refresh period. To read data, set the proper control bits and then move the data input to IR n+2 to the desired storage location after checking the flags to confirm that the desired data has been input. Individual control bits and flags are described following the allocations table below. IR Bit Allocations Bit Output IR n Input IR n+1 IR n+2 IR n+3 00 Point 1 Control Bit Point 1 Read Flag 01 Point 2 Control Bit Point 2 Read Flag 02 Point 3 Control Bit Point 3 Read Flag 03 Point 4 Control Bit Point 4 Read Flag 04 Point 5 Control Bit Point 5 Read Flag 05 06 Point 6 Control Bit Writing data Point 7 Control Bit Point 6 Read Flag Reading data Point 7 Read Flag 07 Point 8 Control Bit Point 8 Read Flag 08 Normal/Peak Control Bit Disconnection Flag 09 10 Normal/Peak Flag Not used. 11 Not used. 12 Peak Reset Bit 13 A/D Conversion Bit 14 PC Write Completed Bit A/D Read Completed Flag 15 PC Read Completed Bit A/D Write Completed Flag Not used. Point Control Bits Turn ON one of the Point Control Bits to designate the desired input point when writing the number of sampling counts for the mean value and when reading binary-converted data. When using peak hold, turn the A/D Conversion Bit OFF. When not using peak hold, turn this flag ON. Normal/Peak Control Bit Turn this flag and the A/D Conversion Bit ON to read normal binary-converted values and turn this flag and the A/D Conversion Bit OFF to read peak values. Peak Reset Bit Turn this bit ON to reset an input point for which the peak value is being read. A/D Conversion Bit Turn this flag ON when reading normal data, and turn it OFF when reading peak values or writing the number of sampling counts for the mean value. Point Read Flags One of these flags turns ON to designate the input point for which data is being read. Disconnection Flag When the signal line of the point designated by the Point Read Flags is burned out or disconnected, this flag turns ON. The offset must be set to at least 1 V (4 mA) for this flag to work.          Section 4--4 Normal/Peak Flag This flag turns ON when the data being read is normal data and turns OFF when the data is the peak value. Mean Function If the both the Normal/Peak Control Bit and the A/D Conversion Bit are turned OFF, the value in IR n will be read in as the sampling count for the mean value for the input point specified by the Point Control Bits. Specify the sampling count (2 through 9999) for the mean value. Set the count to 0 to turn OFF the mean function for that point. Data must be specified in BCD. Note The scaling function does not work with 4-word operation. 4--4 DA001 through DA005 Analog Output Modules With the DA001 through DA005, the binary-converted value for each output point is placed in a dedicated IR word, i.e., the contents of the IR word allocated to any one output point contains the value of to be converted for output as an analog value.

Although two-word operation simplifies programming and always direct reading of analog input values without delays caused by waiting for the I/O refresh period, it is possible only on CPUs that support the I/O WRITE and I/O READ Instructions, WRIT(87) and READ(88). 5--3--1 Two-word Operation READ(88) are used to program transfer of normal and peak binary-converted analog values from the Analog Input Module to the PLC and WRIT(87) is used to program transfer of parameters from the PLC to the Analog Input Module. When programming, take into account the difference between the time data is written memory and time data is input or output via READ(88) and WRIT(87), i.e., there must be one I/O refresh period between any MOV(21)’s used to set control bits and READ(88) and WRIT(87). 1 scan I/O MOV(21) WRIT(87) refresh When executing WRIT(87) Time Data is written to shared memory Data is output Time lag In the following example, we will use the C500 as an example. All 8 points will be used. Means will be calculated for points 5 through 8, and scaling will be performed for points 7 and 8. The Module will be mounted in IR 00, so that IR 00 will be the output word and IR 01 will be the input word. DM 000 through DM 009 will be used for writing data, and DM 100 through DM 108 will be used for reading data. DM 200 through DM 207 will be used to hold the peak values of points 1 through 8.      Section 5--3 Allocation for Reading Data The following tables show the memory locations to which the program will move the various values resulting from the analog inputs.
