Connecting interfaces for communication

Connecting interfaces for c ommunication
The communication interfaces of the CPU/interface module are connected using
standardized connectors.
Use prefabricated connecting cables for the connection. If you want to prepare
communication cables yourself, the interface assignment is specified in the manuals of the
corresponding modules. Observe the mounting instructions for the connectors.

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.
