Tools

Site-wide navigation and reference tools: browse the canonical reference library, look up terms, compare related standards side-by-side, or jump into the consolidated reference hub.

Use this when

You need a decision aid, a worked scenario, a downloadable template, a crosswalk between standards, or the Python toolkit.

Start here

Standards Finder to establish what applies; Scenarios for end-to-end worked examples.

Next step

Carry results into the matching lifecycle stage, and produce deliverables from the engineering templates.

Scope: Cross-cutting utilities that apply across Fundamentals, Design, Implementation, and Verification. They do not replace authoritative standards text — see the trust boundary.

Tool Pages

Engineering Templates

Downloadable original templates — design basis, SRS, I/O list, wire schedule, loop sheets, FAT protocol, MOC form, and more. Several are generated by the Python toolkit.

Python Toolkit (cst)

The open-source package behind the templates: standards-cited calculators (voltage drop, Art. 430, SCCR), panel design pipeline, commissioning generators, PLC utilities, and diagnostics.

Manufacturer Directory

Curated major-and-notable vendors by category — PLC/PAC, VFDs, servo/motion, SCADA/HMI, and process instrumentation — with selection criteria and honest scope limits.

RAG File Browser

Browse and read every markdown file in the canonical reference library — standards intelligence, design framework, training modules, commissioning checklists, and crosswalks.

Glossary

Cross-linked A–Z glossary of terms and acronyms across Safety, Electrical, Standards Bodies, and Regulatory domains — with standard-page and lifecycle-stage links on each entry.

Crosswalks

Side-by-side standards overlap tables — NFPA 79 ↔ IEC 60204-1, UL 508A / NEC / NFPA 79, IEC 61511 ↔ IEC 61508, IEC 60079 ↔ NEC Art. 500/505, plus a compare-any-two picker.

Reference Hub

Quick-reference architecture and motor-system models — 7-Layer Machine Architecture, Universal Safety Architecture, 15-Standard Compliance Stack, and the Motor Selection Comparison Matrix.

Trust Boundary — Engineering Judgment Required

This site is an independent educational reference for industrial automation standards. It paraphrases and organizes guidance in original language; it is not a substitute for the official published standards, professional engineering judgment, or legal review, and content has not been independently verified against current published editions.

Items marked Review pending await technical review against the identified edition. Items marked Planned have no reviewed source material behind them. Do not rely on this site for compliance determinations, safety-critical design decisions, or legal interpretation.
