Curriculum

What you will learn

Module 01

Why Open Process Automation

The business drivers behind OPA — vendor lock-in, lifecycle cost, interoperability. Why owner-operators are including O-PAS compliance in RFQs today.

  • The legacy DCS problem
  • Total cost of ownership across 25 years
  • The operator's case for open standards
Module 02

The O-PAS Standard — Structure and Scope

How the standard is organised, what it specifies, and what it deliberately leaves open. Reading an O-PAS conformance profile.

  • O-PAS v2.1 parts and their relationships
  • Conformance levels and profiles
  • What O-PAS does and does not mandate
Module 03

Reference Architecture

The three-layer OPA architecture — field, control, and information — and how components interact across the standard's defined connectivity framework.

  • Distributed Control Node (DCN)
  • Advanced Computing Platform (ACP)
  • Connectivity Framework and OPC UA
Module 04

Interoperability and Portability

How O-PAS achieves interoperability between components from different vendors, and what portability means in practice for control applications.

  • Interface standards and profiles
  • Application portability across DCN vendors
  • Multi-supplier integration patterns
Module 05

Security Architecture

Cybersecurity requirements within O-PAS and how the standard aligns with IEC 62443 for industrial control system security.

  • IEC 62443 security levels in OPA context
  • Zone and conduit model
  • Authentication and access in open systems
Module 06

Brownfield Migration Fundamentals

How to approach migrating an existing DCS plant to an OPA architecture — assessment, phasing, and risk management.

  • Migration readiness assessment
  • Phased cutover strategies
  • Legacy I/O and field device integration
Module 07

Building the Business Case

How to quantify the value of OPA for your facility and present it to leadership. Lifecycle cost modelling, TCO comparison, and risk framing.

  • TCO model: OPA vs proprietary DCS
  • Sensitivity analysis for brownfield sites
  • Presenting to CFOs and executive sponsors
Module 08

Getting Started — Pilot and Procurement

Practical first steps: scoping a pilot, writing O-PAS requirements into an RFQ, and identifying capable suppliers and integrators.

  • Pilot scope and success criteria
  • O-PAS conformance clauses for procurement
  • Evaluating vendor conformance claims
