It was developed for an internal project called 3Rates @ BorsodChem, which provides data to calculate CR KPI.
Why is the weird name of this repo?
In BC's 3Rates project I developed applications to calculate KPI's for every plant from Alarms (ISA18.2 - AR), Control Loop (CR) and Interlock (IR) operation modes. Some tags in Historian representing control loop operation modes (datatype is string). Full automatic operation is the aim and these KPI values are helping to create a measure.
I made this part of the project public in hope to help someone else to query data from Proficy Historian using Proficy.Historian.ClientAccess.API
