SafeEthernet
Wiring Example
The following scheme shows an example of SafeEthernet protocol and Modbus
protocols networking:
Elements of the network
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.
