Work on Part 5 of the ISA-88 standard is beginning, says the Instrumentation, Systems and Automation Society.

The Instrumentation, Systems and Automation Society’s ISA-SP88 committee has announced it is beginning work on Part 5 of the widely used ISA-88 series of batch control standards.

The Part 5 standard, to be entitled "Modular Concepts for Automated Control Systems," will define methods for developing a library of automation control components that can be supported by automation vendors for all types of manufacturing, the ISA said.

“The components that we want to specify will provide a base of commonly used automation functions that encourage modularity and define common methods for component interaction in batch, continuous, and discrete manufacturing,” said SP88 chair Dennis Brandl, President of BR&L Consulting, Cary, N.C.

Command & control

“Our goal is to provide standard terminology, command and control functionality, a way to describe and identify each modular component, a method for exchanging component definitions, and a method for intercommunications between components,” said Dave Chappell, of The Procter & Gamble Co., in Westchester, Ohio, who will serve as the Part 5 Working Group chair.

Proposed tasks for the Part 5 Working Group include:

• Refining the ISA-88 models for automation across all types of manufacturing. This will encourage and support a layered and hieratical architecture that provides modularity and common methods for the automation modules to interact with one another This model will encompass the control module, equipment module and unit layers in the ISA-88 physical model

• Refining the definitions in ISA-88 Part 1 that relate to coordination control, recipe procedural control, equipment procedural control, and basic control

• Developing a method/approach that will guide the development of a library of automation components that can be supported by all automation vendors to provide a common base of functionality

• Developing physical models that support the concepts of this standard and can be used to clearly communicate the concepts and approaches for batch, continuous and packaging

• Refining the definitions of modes to support use across all of manufacturing, and identifying the use of a "Mode-Matrix" as many types of manufacturing use that description

• Inclusion of any PackML (Packaging Machine Language) guidelines which are consistent with ISA-88 Part 5.

The Working Group, currently recruiting volunteers, will meet May 16-18in Cincinnati. Anyone interested in participating in the meeting or becoming a member of the Working Group may contact Charley Robinson at crobinson@isa.org or Dave Chappell at chappell.da@pg.com,/a>.
