14.3 Replacement of I/O modules and front connectors
When the front connector is inserted in the F-module, the electronic coding element engages
completely in the front connector. If you remove the front connector from the F-module, the
memory with the PROFIsafe address of the fail-safe module remains in the front connector.

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
or coding elements from the new I/O module.
