Replacing A Front Connector - Siemens SIMATIC S7-1500/ET 200MP System Manual

Procedure
To replace the I/O module, follow these steps:
The I/O module to be replaced is uninstalled.
You can find information on removing the I/O module in section Installing I/O modules
(Page 146).
1. For a new I/O module, use a screwdriver to break out the half of the mechanical coding
element that is designated for the front connector.
Note
The arrangement of the mechanical coding element depends on the module type: First,
check the position of the coding element on the front connector before you break out the
matching half from the I/O module.
For a new fail-safe module you must also remove the electronic coding element from the
F-module.

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.
