Ethernet ModbusTCP to Modbus RTU Master gateway.
The popular Modbus protocol is commonly used on serial devices. The Modbus protocol requires very exact timing and quick resposes, which make it difficult to use protocols such as Modbus on a normal Serial Server.
To be able to control Modbus devices over Ethernet, an Ethernet version of Modbus, Modbus/TCP has been devloped by the the Modbus organisation. Modbus/TCP encapsulates the Modbus protocol within an IP frame of TCP/IP. Basically the Anybus X-gateway TCP-RTU Gateway handles the encapsulation between Modbus/TCP and Modbus-RTU. The Anybus-X TCP-RTU Gateway supports RS-232 & RS485 through a 9-pole DSUB connector. It supports 10/100Mbps Ethernet through a standard Ethernet connector (RJ-45).
