Overview
The Anybus Modbus-TCP/RTU Gateway allows Modbus RTU devices be connected to a
Modbus TCP network. The gateway functions as a Modbus TCP server and performs a trans-
parent conversion between the two protocols. All Modbus accesses that are not addressed to
the virtual slave of the Anybus Modbus-TCP/RTU Gateway will be forwarded to the Modbus
RTU network.
The maximum frame length (number of registers) that can be used is limited only by the Modbus
specification and the functionality of the connected Modbus RTU devices. All Modbus function
codes are supported.
Configuration is carried out using the built-in web interface. The IP address of the gateway can
be set using the Anybus IPconfig utility.
