PLC FAT and SAT checklist: test behavior and handover evidence
Plan factory and site acceptance around requirements, observable results, failure states, approved changes and recoverable project files.
Site acceptance test (SAT)
An agreed test of installed equipment and interfaces under the site’s approved conditions.
SAT checks must be tied to project requirements and executed through controlled site procedures. Factory simulation is useful prior evidence but does not replace installed loop and interface checks. Keep safety validation distinct from a general control-system checklist. The acceptance worksheet records failures, retests and remaining gaps.

Hazardous area classification, explained
Zones, divisions, gas groups and temperature classes decide which equipment may sit in a classified area. IP and NEMA ratings answer a different question.
PLC analog input scaling: raw counts, 4–20 mA and diagnostics
Map raw counts into engineering units, check the configured channel range, and keep signal-quality diagnostics separate from the displayed value.
