Brief description of the functional devices

The above application shows the communication between a Safety PLC and a Premium PLC over Ethernet (Modbus TCP/IP protocol) and Ethernet using SafeEthernet protocol. The data exchange between the Safety PLC and the Premium PLC is non-safety data transfer. The two systems can work together sending and receiving data in both directions using Modbus TCP/IP protocol. In this case, it allows non-safe data transfer over Ethernet through the Safety PLC.

Now, the data from a safety-related input can control a safety output within the Safety PLC system and a non-safety output through the Premium PLC system. The PLC system can transmit its non-safe data over Ethernet controlling a non-safety- related output. This allows the cabling system to be used to transfer both safe and non-safe data.
