A line in the sand: Equipment Phase
The ISA SP88 Part 1 group has made the decision to confine their models and descriptions around control what currently exists for the Equipment Phase. It will be the job of the Make2Pack Part 5 group to develop the concepts of the Process/Machine Task Strategy that exists as Equipment Control.
This will include finding an acceptable name and/or definition for the agreed to concept of a procedural entity that is equipment control and not commandable by a recipe, which is what the Make2Pack group has been calling Equipment Sequenced Control. We will continue with the concepts of only three types of Control.
For more about types of control, see the March 19 posting, “Bigfoot Lock Ness Monster sighted! Control types” and also scroll back through prior postings.
I’ll write more tomorrow about each part of the diagram below.
