The application above shows the combination of a Safety PLC system and a Premium PLC system connected via Modbus serial. The data exchange between the Safety PLC system and the Premium PLC system over Modbus serial is non- safe data transfer. The communication allows the two systems to work together. The PLC system can send the non-safe data over to the Safety PLC. The Safety PLC can transmit the non-safety-related data over Ethernet to one of the remote I/O modules. The module can control a non-safety-related output. This enables the use of a single transmission line over large distances for safe and non-safe data transfer.
