5.11.1Installing and Removing the Interface Submodules

!

Installation

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.

2Switch off the power supply of your PLC.

3Remove the CPU.

4Remove both screws on the submodule slot.

5Remove the coverplate.

6Insert the interface submodule through the front plate into the plug-in connector (components in the same direction as the CPU).

7Secure the submodule with the two screws (see step 4).

8Insert the CPU in the central rack.

9Switch on the power supply of your PLC again.
