Allen-Bradley Unsolicited Ethernet

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.

Features

• Acts as a single simulated Allen-Bradley PLC-2
• Up to 256 devices may connect to the simulated PLC-2 at any time
• Sockets used by incoming connections are aged according to activity level
• All major memory and data types supported

A driver is a software component that enables KEPServerEX to meet the communication requirements of a specific device, system, or other data source. The driver handles all proprietary communications between the data source and KEPServerEX; KEPServerEX handles all OPC or proprietary client communications between the driver and the client application(s).

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve. All OPC client interfaces can connect to KEPServerEX without additional charge.
