Characteristics of the front connector

Introduction
The sensors and actuators of your plant are connected to the S7-1500 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.
