The Open Process Automation Standard (O-PAS standard) is developed by the Open Process Automation Forum (OPAF) and published by The Open Group..[1] It defines a standards-based, open, secure, and interoperable process control architecture.[2][3] As an open standard it addresses the business problem of proprietary lock-in experienced by companies that use industrial control systems.[4] The standard enables innovation in the process automation market.[5] The scope of the standard currently excludes safety instrumented systems and field devices[6] like instrumentation and actuators.

O-PAS System Attributes

edit

The O-PAS standard defines 23 quality attributes[7][8], three of which are foundational quality attributes: safety, reliability, and securability[9]

3 Foundational Quality Attributes
Attribute Description
Safety The expectation that a system or component does not, under defined conditions, lead to a state in which human life, health, property, or the environment is endangered.
Reliability The ability of a system or component to perform its required functions under stated conditions for a specified period of time.
Securability The ability of a system or component to be protected against unauthorized access or modification throughout its lifecycle

The O-PAS standard Part 1 focuses on an additional four quality attributes that are critical to success: interchangeability, interoperability, portability, and modularity[9][8].

Structure of the O-PAS Standard

edit

The O-PAS standard is available to the public for download free of charge on the publisher's website.[19] The standard contains 14 different chapters where each part addresses a different topic and a glossary[20][21][22][23]

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.[24] 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[25] 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.[26][27] 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[28]. 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[29] and Field Trial[30]
  • Georgia Pacific Demonstration Board[31]
  • Petroleum Development Oman Field Pilot[32]
  • Petronas Test Bed and Field Trial[33][34]
  • Reliance Industries Test Bed[34]
  • Saudi Aramco Test Bed[35]
  • Shell Test Bed[34]

Certification and Test Tools

edit

O-PAS certification is due to launch in Q4 of 2024.

The certification program requires third party verification for each O-PAS Profile. This must be done by O-PAS Recognized Verification Labs. The exceptions to this rule are for those requirements that involve other certification bodies. The OPC UA Connectivity Profile (OCF-001) and Global Discovery Service (GDS-001) are two profiles that must be verified by the OPC Foundation.

In June 2024, the OPC Foundation announced availability of verification for OCF-001 and GDS-001 O-PAS profiles in the OPC UA Profile Reporting Application.[36][37]

Each Profile requires the SEC-F-001 Security Facet. This facet is derived from the ANSI/ISA-62443-4-2 SL2 security requirements. In order to verify this facet, the supplier must use an ISASecure Lab[38]. In August 2024, the forum selected ISASecure as the exclusive verification provider for security requirements[39].
