Modicon® Modbus® RTU Master (serial) Driver
Kepware's 32 bit Modbus® RTU device driver works in conjunction with KEPServerEX, to provide data exchange between OPC Clients and Modbus® RTU protocol compliant PLCs and Devices. Special handling has been added to support the native memory formats of the Omni Flow computer including string support. Additional configuration parameters allow this driver to tailored to a wide range of Modbus® RTU compatible devices including JBUS. KEPServerEX automatically optimizes your data acquisition based on client demand. Data integrity is insured with the extensive error handling features of KEPServerEX.

The Modbus® RTU 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. For details on Automatic Tag Database Generation, go here>

This driver is part of the KEPServeEX Modbus® OPC Server Suite. Purchasing either the Modbus® RTU serial, Modbus® RTU Slave serial, Modbus® ASCII serial, Modbus Plus™ (SA85), or the Modbus® Ethernet TCP driver entitles you to all five drivers.
