Product Description

ModbusTCP Slave/Server – Modbus RTU Slave Industrial Network Gateway

The ModbusTCP Slave/Server – Modbus RTU Slave Industrial Network Gateway copies I/O-data in both directions thus enabling data exchange between the two networks. Default I/O configuration is 20 bytes Input and 20 bytes Output. Changing default settings is very easy using the windows based configuration software Anybus Configuration Manager X-gateway from HMS (free of charge).

The Anybus OPC Server is supported and included with this X-gateway. It enables fast and dynamic transfer of fieldbus data to and from e.g. SCADA/HMI/Enterprice level systems based on Microsoft Windows.

This gateway is a true Layer 7 gateway that converts application data to/from Ethernet Modbus/TCP <=> Modbus RTU, providing independant handling of each communication interface. 
For a transparant gateway between Ethernet Modbus/TCP <=> Modbus RTU, please look at the HMS part number AB7702 

The Modbus-TCP interface consists of an embedded ModbusTCP 10/100 Mbit/s 2-port Ethernet interface with IT functionality such as WEB-server, SSI-scripts, Flash file system, FTP-server, Email client, Telnet etc. It is possible to build web pages displaying and controlling a factory floor process with data from the other connected network. The EtherNet/ModbusTCP interface module is certified by the Univeristy of Michigan and has proven conformance and interoperability with leading PLC´s, HMI´s etc. The 2-port Ethernet interface will allow daisy chaining thus removes the need for any external switch.

The Modbus RTU Slave interface is implemented according to Modbus Protocol ref guide (PI-MBUS-300). All data is mapped to 3x and 4x Modbus areas meaning the Input Status and Output Register Word areas. The Modbus RTU standard baudrate is 19200 Bit/s but can be modified on the gateway between 1200 Bit/s to 57 600 Bit/s.
