For three days in the Dayton Airport Hotel, April 15-17, 10 Make2Pack ISA88 Part 5 committee members have gathered. We’re continuing to develop Working Draft 5 and deliver related explanations for Phase Interface, Data Control Component, the role of Custom Logic, and refine and deliver the Control Component Command interface.
ISA88 Part 5 demonstrations such as this one aim to ensure the models work before they’re made part of the standard.

Refinement for the line in the sand between ISA88 Part 1 and Part 5

April 15, 2008 | Link This | Email this | Comments (0)

As both of these groups, ISA88 Part 1 and Part 5, continue to develop and move forward I’d like to share a newer vision of Make2Pack as represented in the attached diagram.
Needed: An interface between recipe control and detailed equipment control.

The Make2Pack Part 5 effort is focused on the Process/Machine Task Strategy. To understand how that works with the rest of 88 there needs to be an interface between the recipe control (a term not current...Read More

A line in the sand: Equipment Phase

March 30, 2008 | Link This | Email this | Comments (0)

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.

Bigfoot, Lock Ness Monster sighted! Control types

March 19, 2008 | Link This | Email this | Comments (0)

After several years of searching it seems there really may be an additional component to the ISA88 list of control. The Make2Pack effort has been struggling with this often misunderstood concept since its start. Sometimes there seemed to be something between the ISA88 Equipment Phase Procedural Control that is capable of being directed by a Recipe and Basic Control. Like Bigfoot and Nessie this elusive concept between Equipment Phase Procedural Control and Basic Control had many sightings but real proof has been difficult to sustain for the community at large.

After a recent ...Read More
