Replacing an I/O module

Introduction
● When the front connector is first inserted into the I/O module, a part of the coding element
clips onto 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 an I/O module with the same type of module, the correct coding element
or coding elements in the case of F-modules are already present in the front connector.
Result: Before inserting the previous front connector, you must remove the coding
element(s) from the new I/O module.
Procedure
To replace the I/O module, follow these steps:
You have already uninstalled the I/O module.
You can find information on removing the I/O module in section Installing I/O modules
(Page 61).
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.
Not e
The arrangement of the mechanical coding element depends on the module type: 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.

2. Insert the existing front connector into the new I/O module (same module type) until your
hear it click into place.
