About the Anybus® Modbus-TCP/RTU Gateway

General Information

The Anybus® Modbus-TCP/RTU Gateway can be used to connect a Modbus/TCP master to one or
several Modbus/RTU slaves. The transparent Modbus TCP/RTU gateway will act as a Modbus/TCP
slave on an Ethernet network, and transform the queries to the Serial Modbus network, and send back
the Modbus/RTU slave response to the Modbus/TCP master.

The Anybus Modbus Gateway supports RS-232 through a 9-pole DSUB or RS-485 through the screw
terminal block on the other side of the module. It supports 10/100Mbps Ethernet through a standard
Ethernet connector (RJ-45). It can be configured via a web-interface or by using the Anybys IPConfig
utility. It also contains a Flash memory for easy software updates.
