5.6 Installing I/O modules
Introduction
The I/O modules are installed following the CPU. I/O modules form the interface between the
controller and the process. The controller detects the current process state via the connected
sensors and actuators, and triggers the corresponding reactions.
Requirements
The following preconditions have to be fulfilled to mount an I/O module:
● The mounting rail is installed.
● The CPU is installed.
● In the module / CPU located on the left next to the I/O module, a U-connector is inserted
on the back right.
Tools required
Screwdriver with 4.5 mm blade
Installing I/O modules
Proceed as follows to install an I/O module:
1. Insert a U-connector into the back right on the I/O module.
Exception: the last I/O module in the assembly.
2. Install the I/O module on the mounting rail and slide the I/O module up to module on the
left.
3. Pivot the I/O module towards the back.
4. Fasten the I/O module (torque 1.5 Nm).
