Communication system, devices of the communication sytem and method for the device

A coordinator device for a communication system, the coordinator device comprising:

• a power output interface for coupling to a power supply line,
• a communication interface for coupling to a communication line,
• a communication unit,
• a power supply interface,
• a first fuse unit, and
• a second fuse unit,
• wherein the first fuse unit is coupled between the power supply interface and the power output interface to provide electrical power at the power output interface;
• wherein the communication unit is coupled to the communication interface to transmit or receive communication signals;
• and
• wherein the second fuse unit is coupled between the power supply interface and the communication interface to provide electrical energy at the communication interface.

A periphery device for a communication system, the periphery device comprising:
