Controls Health Check: a 15-minute self-check for your line
Walk one line with this two-page sheet. Every box you can't check is a risk worth knowing about before it turns into downtime.
Free, no signup required. Letter size, 2 pages, made to print and carry onto the floor.
What's on the checklist
29 yes-or-no checks in six sections. Check a box only if you could show it today. "I think so" counts as unchecked.
- Backups & versions: could you reload this machine tomorrow?
- Alarms & HMI: does the screen tell the truth, fast?
- Data you can trust: scaling, quality flags, clock sync, comm dropouts, and documented changes.
- Spares & obsolescence: what happens when a part dies?
- Run hours & preventive maintenance: maintenance by hours, not by guess.
- Safety sanity checks: quick observations, not a safety assessment.
Page 2 has a score guide and space to write down the top three things to fix first on that line.
This self-check is general guidance to help spot common controls risks. It is not an engineering, cybersecurity, or safety assessment.
