Modbus Plus OPC Server

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

The Modbus Plus 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.
