The C-PLUG has degree of protection IP20. The degree of protection of IP65 components is ensured by the design of the target device. The power supply is also provided by the end device.

The C-PLUG is inserted in the associated slot of the SIMATIC NET component. The configuration data are automatically saved to the C-PLUG during device start-up and reconfiguring.

If a device needs to be replaced, the C-PLUG is simply removed from the failed component and plugged into the replacement device. The replacement device installed in the network or automation system now starts up automatically with the same device configuration as the failed device.

To prevent unintentional removal or falling out, the C-PLUG slot is usually located on the rear of the terminal devices.
