MODBUS is a communication protocol widely used for monitoring and controlling various industrial automation equipment represented by PLC (Programmable Logic Controller). It was developed based on serial, but it also has been expanded to network version for application in various communication environments.

The ezTCP SMG-5420 is an industrial Modbus Gateway that converts and routes Modbus data between the serial line and Modbus/TCP. This can help to communicate between the Modbus master (or slave) of the serial line and the Modbus slave (or master) of the network.

The SMG-5420 provides 10/100Mbps Ethernet and RS422/RS485 serial port connectivity.
