Introduction 5 (20)
2 Introduction
Fig. 1 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.

Installation 6 (20)
3 Installation
3.1 Mounting on DIN Rail
Mounting
Fig. 2 Mounting on DIN rail
1. Hook the unit onto the upper lip of
the rail.
2. Press the unit towards the rail until it
snaps into place.
Removing
Fig. 3 Removing from DIN rail
1. Insert a flat-head screwdriver into
the slotted tab on the bottom of the
unit and pull the tab gently
downwards.
2. Pull the bottom end of the unit free of
the rail and lift the unit from the rail.
3.2 MAC ID and Default IP Address
The default IP address of a Anybus Modbus-TCP/RTU Gateway is 10.200.1.n, where ncorre-
sponds to the last number in the MAC ID, which is printed on the label on the side of the unit.
The MAC ID is in hexadecimal format. If the MAC ID is 00:30:11:FA:00:1F, the IP address will
be 10.200.1.31, since the hexadecimal value 1F = 31.
