ISA88 Technical report discussion uncovers new ground...Part 2 of 4
Here’s the second concept intended to supplement those in ISA 88.00.01 standard in context of the TR88.00.02 Technical Report, as offered by Randy Dwiggins of Maverick Technologies.
For more explanation, see ISA88 Technical report discussion uncovers new ground...Part 1 of 4
Here is the second part:
2. Base State Model
The Base State Model defines a complete fixed set of defined unit states, unit state commands, and unit state transitions. Each Equipment Unit Procedure will comprise a subset of the same base state model, but with uniquely associated control definition references.
Note: The Base State Model is an allowed extension of the example procedural state model described in ISA 88.00.01, but for the purpose of this Technical Report is more than an example because it intentionally constrains Equipment Unit Procedure definition in order to enable interoperability.
I'll post part 3 later this week. As stated, we hope these can be used in a future ISA88 revision. Please comment!
