Controls, Safety & OT

Trace the signal.
Verify the response.

Connect instrumentation, control logic, safety-system interfaces, and operating information through documented verification.

Verification across the signal path.

Tag and range checks, calibration evidence, signal paths, loop records, device status, and field-to-system correspondence.

I/O, logic, operator displays, alarms, trends, permissives, operating modes, and communications interfaces.

Cause-and-effect, detector mapping, outputs, voting, permissives, bypass status, and traceable approved test records.

Sample-system interfaces, analyzer communications, data quality, meter signals, and reporting alignment.

Configuration and firmware records, backups, restore evidence, access roles, remote-access constraints, and support ownership.

Display navigation, alarm response, abnormal scenarios, procedure alignment, training records, and control-room handover.

The handover record

A completed test should be traceable to the device, the configuration, the expected behavior, the observed response, and the resulting disposition.

Safety-system testing is scoped to approved requirements and procedures, with defined authority and project safety controls.

Identify approved logic, settings, device information, and the records needed to support later changes.

Capture conditions, observations, exceptions, corrective action, and retest results.

Clarify ownership of backups, accounts, records, vendor support, and remaining limitations.
