Historian-sourced loop performance
PlantTriage monitors control-loop performance directly from a plant’s data historian.
PlantTriage monitors control-loop performance directly from a plant’s data historian. Using OPC HDA, the system interfaces to OSI PI Historian, Honeywell PHD, AspenTech infoPlus.21, and Invensys AIM*Historian, as well as any historian that supports OPC HDA. HDA, or Historical Data Access, is a new standard from the OPC Foundation. The simple OPC HDA connection lets control engineers view past data and apply PlantTriage tools to diagnose, tune, linearize, and decouple problems.
