Modbus Ethernet

The Modbus Ethernet device driver works in conjunction with KEPServerEX to provide data exchange between OPC clients and Modbus Ethernet 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 Ethernet driver supports master and slave operations simultaneously. The slave 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 KEPServerEX. This time-saving step instantly makes all of the relevant PLC data available to your OPC client applications.
