Description
The PSI-MOS-RS232/FO… can be used to convert V.24
(RS-232) interfaces to fiber optics.
The main advantage of the PSI-MOS fiber optic
transmission system is the electrically isolated connection
of devices, which prevents the negative effects of voltage
equalization currents and electromagnetic interference on
the data cables. This increases the overall availability of the
system and improves flexibility in terms of the design of the
bus topology for point-to-point connections and in star
structures.
Up to ten fiber optic modules can be connected side by side
to form optical star couplers, which are tailored to the
specific application. Cross-wiring within a modular star
coupler is created automatically via the backplane. The
system supports progressive transmission speeds from
4.8 kbps to 115.2 kbps.
When the devices are in redundancy mode, a minimum data
rate of 9.6 kbps must be observed.
PSI-MOS-RS232/FO… E termination devices convert a
V.24 (RS-232) interface to a fiber optic cable. They are ideal
for point-to-point connections.
PSI-MOS-RS232/FO… T fiber optic T-couplers convert to
two fiber optic cables.
PSI-MOS-RS232/FO 660... devices are networked using
polymer fiber cable for distances up to 100 m and HCS fiber
cable for up to 800 m. They are connected via F-SMA quick
mounting connectors, which can be assembled locally
within a few minutes.
PSI-MOS-RS232/FO 850 ... devices are available for
longer paths and can be used for distances up to 2800 m
using HCS fiber cable and B-FOC (ST®) fast connection
technology and up to 4800 m using multi-mode glass fiber
cable.
The PSI-MOS system can be used with input voltages from
18 V DC to 32 V DC and in a temperature range from -20°C
to +60°C.
The devices are also equipped with comprehensive
diagnostic functions to increase system availability and to
simplify startup. The integrated fiber optic diagnostics
permanently monitor the optical transmission quality.

Definition of fiber optic diagnostics
–
The quality of the path is determined using the incoming
optical power Popt and displayed using the LED bar graph.
–
DIP 2 is used to switch the transmitters in the idle state (rest
period between transmitting data) to steady light (INVERS),
to enable continuous fiber optic diagnostics.
–
If DIP 2 is set to "ON" (NORM), fiber optic diagnostics are
not available.

and the switch contact opens. Data communication is still
possible.
NOTE: If DIP 2 is set to "ON", fiber optic
diagnostics are not available via the LED bar
graph.
The LED bar graph can light up at high
transmission speeds or flash at low transmission
speeds. This display does not correspond to
continuous evaluation of the optical power.
7.1
Port assignment
The port assignment of the PSI-MOS-RS232/FO… can be
adapted via DIP 1. It is thus possible to adapt the direction
of data communication between the V.24 (RS-232) interface
and the fiber optic ports to the desired application.
–
–
Only one V.24 (RS-232) device may be connected to a
V.24 (RS-232) interface
The V.24 (RS-232) devices can be addressed via
communication software
Fiber optic ports A always communicate in the direction
of the master
Up to 10 fiber optic converters are supported in the line
DIP 1 = OFF (LINE)

Figure 4
Port assignment for a linear structure
Port assignment for a star structure
The V.24 (RS-232) interface communicates bidirectionally
with port A and port B. Port A and port B are not connected.
Therefore communication for the connected V.24 (RS-232)
devices is generally in the direction of the master. In the star
coupler, the backplane is used to connect all the fiber optic
ports to all the V.24 (RS-232) interfaces.
Requirements
– Only one V.24 (RS-232) device may be connected to a
V.24 (RS-232) interface. This is also true for the star
coupler to which the master is usually connected. The
V.24 (RS-232) interfaces of the star coupler are
connected via the backplane, which means that the
position of the master can be freely selected.
– The V.24 (RS-232) devices can be addressed via
communication software.
– DIP 1 = "ON" (STAR)
Port assignment for a linear structure
The V.24 (RS-232) interface and port A communicate
bidirectionally with one another. Port B only sends and
receives in the direction of port A. Therefore communication
for the connected V.24 (RS-232) devices is generally in the
direction of the master. The backplane is not used.

Activating the redundancy function (DIP 3)
NOTE: In redundancy mode, mixed operation
with fiber optic converters from third-party
suppliers is not supported.
For increased availability, redundant fiber optic connections
can be created using T-couplers.
In this case, the redundancy function must be activated at
the start and end of the redundant fiber optic connection.
•
To do this, set DIP switch 3 (REDUNDANCY) to "ON".
When the redundancy function is enabled, data
communication takes place via fiber optic port A by default.
In the event that the signal level of the standard cable drops
to a critical level, it automatically switches to port B.
NOTE: Always connect redundant fiber optic
connections from fiber optic port A to port A of the
opposite device or from port B to port B of the
opposite device.
Connection to fiber optic interfaces from
third-party suppliers (DIP 2)
NOTE: In redundancy mode (DIP 3 = "ON"), the
idle setting is always INVERS. DIP 2 then has no
function. This can limit mixed operation with
third-party suppliers.

DTE/DCE adaptation
The TxD and RxD cables can be crossed internally using the
DTE/DCE slide switch (8 in Figure 3 on page 9), thus
enabling user-friendly adaptation to DTE or DCE interfaces.
– DTE: Connection to data terminal equipment
Set the switch to "DTE" (default setting for the majority
of applications).
– DCE: Connection to data communication equipment
Set the switch to "DCE".
If you do not know which type of interface is connected, you
can determine the correct configuration by testing
(DTE/DCE slide switch).
10.4
Wiring the switch contact
PSI-MOS-RS232/FO… converters are equipped with a
floating switch contact for error diagnostics (connection
terminal blocks 3 and 4 in Figure 3 on page 9). This contact
opens on the affected device if:
– The supply voltage fails
– An interrupt is detected on the fiber optic path
– The system reserve for the fiber optic path is not
reached
The switch contact is an N/C contact and can be connected
to a local digital input, e.g., on the PLC, to support error
detection.
When using a device topology (modular star coupler), the
individual contacts can be connected to separate input
points or the individual contacts can be looped to generate
a group message (Figure 13).
NOTE: The maximum load capacity of the relay
contact is 60 V DC/42 V AC, 1 A.
