General Automation Concepts Glossary (1/2)
Cross-cutting industrial-automation concepts that span multiple disciplines. This page (1 of 2) covers 112(r) Risk Management Plan to MTTA.
Some automation vocabulary refuses to stay in one discipline: redundancy schemes, engineering-unit conventions, project roles, and cross-cutting concepts that a controls engineer, an operator, and an IT administrator all use differently. This is the home for those genuinely cross-domain terms. If a term here grows a clear disciplinary home as the glossary evolves, it moves there.
