Replacing A Front Connector - Siemens SIMATIC S7-1500 System Manual

13.2.3

Replacing a front connector

Introduction
● When the front connector is first inserted into the I/O module, a part of the mechanical
coding element engages on the front connector.
● In the case of fail-safe modules, the electronic coding element with the PROFIsafe
address of the F-module also engages completely in the front connector.
When you replace a defective front connector with a new front connector, you must transfer
the coding element(s) to the new front connector.
Procedure
You have already removed the front connector from the module and loosened the wiring. If
you are using the front connector for an analog module, you also need to remove the power
supply element and shield element. Proceed as follows to replace the front connector:
1. Carefully remove the mechanical coding element from the front connector. Take care not
to damage the coding element.

The coding elements are dependent on the module type.
2. Insert the removed mechanical coding element into the new front connector.
