Drivers

Product Overview

The Allen-Bradley Server Ethernet device driver works in conjunction with KEPServerEX to provide data exchange between OPC/DDE clients and Allen-Bradley PLC-2 compliant PLCs via Ethernet. The driver allows an OPC client application to appear as 1 to 256 Allen-Bradley devices on the network. The server-client mode allows the server to receive data by exception from an Allen-Bradley sesrver. As with any client device, the Allen-Bradley Server driver only transfers data when being read or written by a server KEPServerEX automatically optimizes data acquisition based on client demand. Data integrity is ensured with our extensive error handling.
