Honeywell PKS OPC Connectivity


Thread Starter


I have a number of HART digital positioners mounted to control valves connected to my Honeywell Experion PKS system. I can use the Honeywell Controller to do many basic functions with the positioners such as change set point and create basic loops. When I try to read the devices in other programs connected to the Honeywell system using OPC, OPC does not recognize any of the devices.

What triggers do I need to enable in the PKS controller or OPC so that the OPC network recognizes the devices in the Honeywell System so that they the devices can communicate with other OPC enabled software?
