Product Overview

The Allen-Bradley ControlLogix Unsolicited driver for KEPServerEX acts as a simulated Allen-Bradley ControlLogix PLC allowing unsolicited communications between KEPServerEX and Allen-Bradley Logix devices, eliminating unnecessary PLC "Read" communications. The driver supports the CIP Data Table Read and Write Messages from the Logix family of controllers. The ControlLogix Unsolicited driver will only transfer data when being read or written to by a Logix master. The data acquisition is automatically optimized by KEPServerEX based on the master demands.

Release Notes

6.6.348.0

11/14/2018

  • Updated the Native tag database so that it may be directly manipulated either in the Configuration GUI or via the Configuration API.

6.2.460.0

7/6/2017

  • Added Chinese language support.

6.0.2107.0

11/15/2016

  • Added German language support.
  • Added Japanese language support.

5.13.191.0

10/15/2013

  • Enhanced the driver to support ODVA Conformance. New features include Connected Messaging, ODVA Member ID, and EDS file.
  • Improved error handling so that unsupported data types (such as BCD and LBCD) will result in an "Invalid data type" error message instead of an "Out-of-range" error message.
  • Corrected a problem in dimension detection for tag paths that contain 16 bit element offsets.
  • Corrected a defect in element count calculation that was exposed by the Allen-Bradley Micro800 Ethernet Driver. The element count is now correct if the element offsets indicate that less than the specified element count need to be returned.
  • Runtime tag values are no longer reset when a device's slot configuration is changed.
  • Removed support that allowed users to specify Port 0 (system determined) for the EIP server binding. Because the driver binds a listen socket to both UDP and TCP for conformance, these ports must be the same.
  • Removed the potential server hang that could occur if EIP messages were being processed while a channel's Network Interface or Port was changed.
  • Corrected int64<->Double conversion to match behavior in ControlLogix Ethernet Master Driver.
  • Removed support for the Media-Level Redundancy Plug-In because it was never intended.

5.11.250.0

3/5/2013

Added support for strings of INT and DINT arrays.

5.8.109.0

2/21/2012

Initial release of the new driver. It is licensed with either the Allen-Bradley Driver Suite or the Manufacturing Suite, and requires that new licenses be purchased for access. This driver is intended for customers that require the use of CIP Data Table Read and Write Messages from the Logix family of controllers and need to communicate with a driver in an OPC server.


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.
