ISA-S88 Part 5: Modular Concepts for Automated Systems.Dan Seger Principal Application Engineer Rockwell Automation

Whats going to be covered? What is ISA-S88? Why was ISA-S88 Part 5 needed? What does it look like? An Automation Federation Organization Whats the current status of development? How do ISA-S88 Part 1, Part 5, and PackML relate to each other.

First, a little back ground on ISA-S88 ISA-S88 Part1: Batch Control Model. Defines procedural control layers, recipe and equipment separation, and equipment control models This is the Batch Processing View Batch typically has its complexity found here. Control RecipeProcedure ControlProcedure

First, a little back ground on ISA-S88 As a result of ISA-S88 being a Batch focused standard, the focus is on the Procedural control and the Procedural model. The Process Control modules were not focused on.Control RecipeProcedure ControlProcedure

What is ISA-S88 Part 5: Modular Concepts for Automated Systems? Part 5 is focused on clarifying and extending the definitions of Process control modules. Because these modules are important to all processing disciplines, an effort is being made to avoid making Part 5 batch processing specific.Control RecipeProcedure ControlProcedure

What is ISA-S88 Part 5: Modular Concepts for Automated Systems? This Part 5 standard defines the interface requirements for controlling execution of manufacturing tasks in a consistent modular fashion based on the Part 1 An Automation Federation Organization equipment process control concepts. A principal intent of this standard is to provide a clear hierarchical structure for defining and implementing the coordination control requirements that typically occur at the process control module level. This will provide a consistent framework for a very modular and distributed design of these functions with very predictable interactions. Part 5 calls this framework the Automation Module

The Part 5 Automation Module Resource Manager The Resource Manager is designed to regulate who is able to direct the Automation Module. Every Automation Module will have a resource (parent) that directs it. Also it could have one or more subordinate Automation Modules that it directs.

The Part 5 Automation Module The main content of the S88: Part 5 standard will be to define the complete Automation Module. Resource Manager An Automation Federation Functional Manager Organization Functional Strategies Create terminology and definitions for the various IO processes involved with the Automation Module. Examples on how to implement the Resource Manager and Functional Manager A specific Resource Management methodologies will be defined. The ultimate goal is push Object Oriented Programming (OOP) concepts into general automation programming without loosing flexibility on automation platform choice or restricting IP development.

Development Time Line The Part 5 working group expects to have a completed Working Draft available for review in early 08 Final Draft available for the ISA-S88 Committee vote in mid 08 An Automation Federation ISA-S88 Part 5 released as a standard in late 08. Organization

ISA-S88 and PackML Whats the relationship between ISA-S88 Part 1, Part 5, and PackML? S88 Part 1 is focused heavily on defining what procedural control was and the interface model looked like. Butits very batch focused. S88 Part 5 is focused on addressing the definition of what the process control modules are and how to implement them.
