Modbus Ethernet

Product Overview

The Modbus Ethernet device driver provides data exchange between OPC clients and Modbus Ethernet protocol compliant PLCs. Kepware automatically optimizes your data acquisition based on client demand. Data integrity is ensured with our extensive error handling.

Kepware's implementation of the Modbus Ethernet driver supports client and server operations simultaneously. The server mode allows the server to receive data by exception from other Modbus Ethernet devices.

The Modbus Ethernet driver now offers direct integration with Modicon Concept and ProWORX programming packages. If you are using either of these packages, you will be able to directly import the tags used in your PLC application directly into Kepware. This time-saving step instantly makes all of the relevant PLC data available to your OPC client applications.
