Front connector for the I/O modules

Introduction
The sensors and actuators of your plant are connected to the automation system by means
of front connectors. Wire the sensors and actuators to the front connector and then plug it
into the I/O module. You can either wire the front connector in the "pre-wiring position" that
makes convenient wiring possible, or completely, before you insert it into the I/O module.
You can remove the front connector easily from the I/O module with the wiring attached. This
means it is not necessary to loosen the wiring when you replace the module.
