5.11.1 Installing and Removing the Interface Submodules
To use an interface submodule, you must first install it in the CPU (outside
the central controller).
!
Caution
Switch off the power supply of the programmable controller before
removing the CPU.
Install your interface submodule in the following steps:
Step Action
1 Check the jumper settings of your interface submodule:
PG submodule See Section 5.11.2
V.24 submodule See Section 5.11.3
TTY submodule See Section 5.11.4
RS422 A/485 submodule See Section 5.11.5
SINEC L1 submodule See Section 5.11.6.
When the interface submodule is delivered, the jumpers are
already set so that you can usually fit it immediately.
2 Switch off the power supply of your PLC.
3 Remove the CPU.
4 Remove both screws on the submodule slot.
5 Remove the coverplate.
6 Insert the interface submodule through the front plate into the
plug-in connector (components in the same direction as the CPU).
7 Secure the submodule with the two screws (see step 4).
8 Insert the CPU in the central rack.
9 Switch on the power supply of your PLC again.
