Building a factory model with ISA-95
· 11 min read
A factory has no shortage of data. The difficult part is knowing what the data describes and how it relates to everything else.
A tag called Line1.Power might be obvious to the engineer who created it. It is less obvious to a scheduling system trying to calculate the energy cost of a production order, or to someone comparing the same machine across five sites.
To answer those questions, one needs a model of the factory. ISA-95 is a good place to start.
