Modbus Plus

Product Overview

The Modbus Plus device driver works in conjunction with KEPServerEX to provide data exchange between OPC clients and Modbus Plus protocol compliant PLCs. KEPServerEX 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 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.

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 KEPServerEX. This time-saving step instantly makes all of the relevant PLC data available to your OPC client applications.

A driver is a software component that enables KEPServerEX to meet the communication requirements of a specific device, system, or other data source. The driver handles all proprietary communications between the data source and KEPServerEX; KEPServerEX handles all OPC or proprietary client communications between the driver and the client application(s).

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve. All OPC client interfaces can connect to KEPServerEX without additional charge.
