ISA88 Part 5: State Diagram as an example rather than a normative requirement

As the ISA88 Part 1 work approaches completion it appears that the new procedural state diagram (see the example) will become an example and not a requirement.

As the ISA88 Part 1 work approaches completion it appears that the new procedural state diagram (see the example below that Make2Pack had been working with) will become an example and not a requirement.

As the Make2Pack work evolves I don’t think this will be an issue. I think that our contribution will be how to interact with ANY component.

This involves the command and status interaction and not necessarily the control components that drive the Functional Strategy.
