Overview

These Ethernet gateways allow you to easily connect Modbus or SIXNET serial slave devices (such as a controller, PLC, RTU, etc.) to your Ethernet network.

A new capability has been added to this Ethernet to RS232 gateway to pass one user-selected protocol from Ethernet to one slave device (if TCP-based protocol) or multiple slave devices (if UDP-based protocol) connected to the RS232 port, and pass the response to these messages back to the master. Refer to the Selection Guide and Usage Tips for specifications and limitations of this new capability.

Why Ethernet?

Ethernet is now THE world fieldbus standard with more than a 75% share of the industrial network market. In fact, the Fieldbus Foundation has adopted Ethernet as its standard H2 (level 2) network. Ethernet is also inexpensive and very reliable.

Modbus and Ethernet

In the industrial network market, Modbus with TCP/IP is becoming the open standard for Ethernet connectivity. Most major HMI and SCADA packages have added or are adding a Modbus/TCP (Open Modbus) I/O driver. The Ethernet gateways allow you to interface Modbus RTU or ASCII serial devices over your existing Ethernet network. SIXNET also offers a Modbus OPC server that allows any OPC client to access SIXNET I/O.

Legacy Systems

Don’t throw out that old system just yet. With these Ethernet gateways you can add your existing Modbus or SIXNET devices to your high speed Ethernet network. Mix your Modbus devices, EtherTRAK, and other Ethernet units all on the same network. These converters save you time and money by allowing you to upgrade your existing system instead of replacing it.
