8.3 Replacing an I/O module
Introduction
The first time you insert an I/O module, part of the coding element locks into the terminal block.
If you replace an I/O module with the same module type, the correct coding element is already
in the terminal block.
You can find information on the coding element in the section "Inserting I/O modules or slot
cover (Page 100)".

after plugging a module in again.
