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.
Procedure
To replace the I/O module, follow these steps:
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.
Figure 13-3
2. Insert the existing front connector into the new I/O module (same module type) until your
hear it click into place.
