PSL Overview

The PSL (ISO 18629) Process Specificaion Language (PSL) standardization initiative includes the semantics for describing the fundamental concepts of manufacturing processes.

The Process Specification Language (PSL) defines a neutral representation for manufacturing processes. Process data is used throughout the life cycle of a product, from early indications of manufacturing process flagged during design, through process planning, validation, production scheduling and control. In addition, the notion of process also underlies the entire manufacturing cycle, coordinating the workflow within engineering and shop floor manufacturing.

PSL is being standardized within Joint Working Group 8 of Sub-committee 4 (Industrial data) and Sub-committee 5 (Manufacturing integration) of Technical committee ISO TC 184 (Industrial automation systems and integration).

PSL is a multi-part standards effort that currently includes:

1. Part 1: Overview and Basic Principles
2. Part 11: Process Specification Language: PSL-Core.
3. Part 12 : PSL Outercore
4. Part 13 : Time and ordering
5. Part 14 : Resources
6. Part 15 : Activity performance
7. Part 21 : External mapping to EXPRESS
8. Part 22 : External mapping to XML
9. Part 23 : External mapping to UML
10. Part 41 : Activity
11. Part 42 : Time and State
12. Part 43 : Ordering
13. Part 44 : Resources role
14. Part 45 : Kinds of resource sets
15. Part 46 : Processor activities
16. Part 47 : Process intent
17. Part 2xx series: Translator implementation guidelines
