The EtherModbus gateway allows serial Modbus RTUs to communicate and interoperate with Modbus/TCP based controllers. The Modbus standard protocol is an asynchronous protocol designed to connect directly to computer asynchronous ports. Modbus has been extended to operate over Ethernet using the IP protocol suite. The EMB-02 gateway converts between the Modbus TCP/IP protocol and Modbus ASCII/RTU protocols transparently. The EMB-02 enables one or more MODBUS controllers to communicate with Modbus ASCII/RTU based serial RTUs. It will not allow Modbus/TCP RTUs to operate with a serial MODBUS controller.
Modbus, Modbus TCP/IP
