An exception reply is diagnostic evidence. Preserve it and inspect the complete read request.

Separate event timestamps from elapsed durations before accepting a monitoring timeout or delay.

Two engineers can each save a valid configuration while the later save quietly removes the earlier change.

A procurement specification that asks only for a 16-bit input can still produce a measurement unsuitable for the process.

Turn sensor-fault requirements into testable factory acceptance criteria, covering invalid data, visible indication, recovery and safe test boundaries.

Turn a saved monitoring configuration into a testable recovery package, using an isolated drill, clear evidence and a hypothetical acceptance example.

Plan a transmitter range change across input scaling, alarms, trends and reports, with a hypothetical pressure example and a practical acceptance checklist.
