Modbus Ethernet OPC Server - KEPServerEX OPC Servers

Overview

Kepware's 32 bit Modbus Ethernet device driver works in conjunction with our OPC Server KEPServerEX, to provide data exchange between OPC Clients and Modbus Ethernet protocol compliant PLCs. Kepware's implementation of Modbus Ethernet OPC Server supports master and slave operations simultaneously. The slave mode allows the server to receive data by exception from other Modbus Ethernet devices. KEPServerEX automatically optimizes your data acquisition based on client demand. Data integrity is ensured with our extensive error handling.

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 KEPServerEX. This time saving step makes all of the relevant PLC data available to your OPC client applications instantly. Learn more about Automatic Tag Database Generation.

This driver is part of the Modicon Modbus Communications OPC Server Suite. Purchasing either the Modbus RTU OPC Server, Modbus RTU Slave OPC Server, Modbus ASCII OPC Server, Modbus Plus SA85 OPC Server, or the Modbus Ethernet TCP OPC Server entitles you to all five drivers.
