7.10 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. Plug the front
connector with the wired sensors and actuators onto the I/O module.
You can wire the front connector as follows:
• In the "pre-wiring position", which allows a convenient wiring
• 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.
