10.2 Replacement of I/O modules and front connectors
10.2.2
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. When you replace an I/O module with the same type of
module, the correct coding element is already present in the front connector.
Replacing an I/O module
You have already uninstalled the I/O module.
1. With a new I/O module, use a screwdriver to break out the half of the coding element that
is designated for the front connector.

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