Overview

Product Overview

The Modbus Plus device driver provides data exchange between OPC clients and Modbus Plus 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 Plus driver supports client and server paths simultaneously. The server mode allows Kepware to receive data by exception from other Modbus Plus devices. Up to eight simultaneous server paths are supported for maximum unsolicited message processing throughput.

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 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.
