Allen Bradley Unsolicited Ethernet OPC Server

Overview

Kepware's 32 bit Allen Bradley Unsolicited Ethernet device driver works in conjunction with our OPC/DDE Server, 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 AB devices on the network. The slave mode allows the server to receive data by exception from an AB master. As with any slave device, the AB 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.

This driver is part of the Allen Bradley OPC Server Suite. Purchasing either the Allen Bradley Unsolicited Ethernet OPC Server, Allen Bradley PLC5/SLC505 Ethernet OPC Server, the Allen Bradley ControlLogix Ethernet OPC Server, the Allen-Bradley Data Highway Plus OPC Server or the Allen Bradley DF1 OPC Server driver entitles you to all of the drivers.

Note: Does not require the use of RSLinx licenses.
