Beginner's Guide to Open Process Automation
The Beginner’s Guide to Open Process Automation is a practical, plain-language introduction to OPA and O-PAS. It explains the core concepts, architecture, and standards behind open automation, helping end users, engineers, and decision-makers understand what OPA is, how it works, and how it can be adopted incrementally—without hype, vendor bias, or unnecessary complexity.
Rather than focusing on products or marketing claims, the guide emphasizes architecture, interoperability, and real-world considerations. It is designed to help readers build a clear mental model of OPA, understand where it fits alongside existing control systems, and make informed decisions about modernization at their own pace.
