The Open Process Automation Standard (O-PAS standard) is a standard of standards[1] developed by the Open Process Automation Forum (OPAF) and published by The Open Group[2]. The O-PAS standard defines a standards-based, open, secure, and interoperable process control architecture[3]. The O-PAS standard is an open standard intended to address the business problem of proprietary vendor lock-in experienced by companies that use industrial control systems in various manufacturing industries.[4] The technological impact of the O-PAS standard is viewed as a disruptive change to the process automation industry.[5] A key attribute of systems that adopt the O-PAS standard is the decoupling of hardware and software.[6] The scope of the O-PAS standard has intentionally omitted safety instrumented systems.[7]
History[edit]
The O-PAS standard was first published in February 2019[8] as Version 1.0 Preliminary with five parts.[9][10]
The second publication occurred in December 2019 as Version 1.0.[11]
The third publication occurred in February 2020 as Version 2.0 Preliminary.[12][13]
The fourth publication occurred in May 2021 as Version 2.1 Preliminary.[14]
The fifth publication of the standard occurred in February 2023 as Version 2.1 Final.[15]
There are plans to publish a future Version 3.0 of the standard.[16]
Structure of the Standard[edit]
The O-PAS standard is available to the public for download free of charge on the publisher's website.[17] The standard contains different chapters where each part addresses a different topic.[18][19][20][21]
Part 1 Technical Architecture
- A technical overview of the technology and how the entire standard addresses the goals of the architecture
Part 2 Security
- Provides an overview of how the IEC 62443 standard is integrated into the O-PAS standard
Part 3 Profiles
- Details groupings of features and functions in all parts of the standard where product suppliers are expected to demonstrate conformance. Including how products will be tested and certification be granted
Part 4 Connectivity Framework
- Details how the connectivity framework defined in the O-PAS standard is based on OPC Unified Architecture
Part 5 System Management
- Details how the Redfish standard, published by DMTF, is integrated into the standard.[22] The section explains what information should be exposed by software programs, hardware platforms, and other system components
Part 6 Information & Exchange Models
- Part 6.1 Overview and Interfaces
- Part 6.2 Basic Configuration
- Part 6.3 Alarm and Events Configuration
- Part 6.4 Function Blocks
- Part 6.5 IEC 61499
- Part 6.6 IEC 61131
Part 7 Physical Platform
- Defines how the O-PAS standard approaches integration of the InterEdge standard[23] that is developed and published by PICMG
Part 8 Application Portability
- Details the approach to application portability, which will provide end users the ability to move applications, intellectual property, and control strategies between different systems
Part 9 System Orchestration
- Published in February 2024, the document is currently available in snapshot form.[24][25] The document publicly communicates the direction and path to defining a standard around system orchestration. Specifically, system orchestration management to automate functions and give systems the ability to rebalance workloads to ensure desired system performance, improve reliability, and improve system resiliency
Reference Implementations[edit]
The Open Process Automation Forum seems to be aware of the technology life cycle and technology adoption life cycle in efforts to boost industry adoption[26]. A number of reference implementations, proofs of concept, field trials, and test beds have been developed in accordance with the O-PAS™ standard. Publicly announced implementations are listed alphabetically below:
- ExxonMobil Test Bed[27] and Field Trial[28]
- Georgia Pacific Demonstration Board[29]
- Petroleum Development Oman Field Pilot[30]
- Petronas Test Bed and Field Trial[31][32]
- Reliance Industries Test Bed[32]
- Saudi Aramco Test Bed[33]
- Shell Test Bed[32]
