Product Overview

The Allen-Bradley Unsolicited 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 Unsolicited driver allows an OPC client application to appear as 1 to 256 Allen-Bradley devices on the network. The slave mode allows the server to receive data by exception from an Allen-Bradley master. As with any slave device, the Allen-Bradley Unsolicited driver will only transfer data when being read or written by a master. KEPServerEX automatically optimizes your data acquisition based on client demand. Data integrity is ensured with our extensive error handling.

What Is a Driver?

KEPServerEX is more than an OPC server—it's a connectivity platform for industrial automation and IoT. Simply download KEPServerEX, and then select from Kepware's library of more than 150 device drivers, client drivers, and advanced plug-ins to fit the communication requirements unique to your industrial control system.

A driver is a software component that enables KEPServerEX to meet the connectivity requirements of a specific device, system, or other data source. The driver handles all proprietary communications to the data source for KEPServerEX; the client interfaces handle all supported OPC, proprietary, and open standards connectivity to applications that monitor or control the devices.

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve.
