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)".
Module identification - read and transfer data
If data have been configured for module identification in the plant, you must transfer this data
after plugging a module in again.
● Data transmitted to the I/O module for the module identification can be read back into the
project.
Configure the I/O module in HW Config and select the menu command CPU > Upload

● Transfer any data for module identification in the configuration after plugging in the I/O
module.
