Connect each check to an agreed requirement.
Start with the functions in the scope: operating modes, sequences, inputs and outputs, communication mapping, parameters, alarms and permitted operator commands. Define the expected result for each item and record the environment in which it can be checked.
A simulated value can establish that a screen changes correctly, but it does not prove that the field instrument is wired or scaled correctly. Separate software-only checks, hardware-connected checks and installed-equipment checks. Identify who is responsible for each stage rather than recording one undifferentiated passed result.
Check boundaries between suppliers and systems.
For a supervisory project, agree the point list, communication condition, read/write permissions and the operator-station configuration. Identify who provides each controller or subsystem and who can resolve an inaccurate or unavailable data point during integration.
Where local panels and central controls coexist, check the agreed selector states, command paths and feedback. Requests issued from an interface should be considered separately from the equipment response. The exact confirmation and fault behaviour is a project design decision, not a universal checklist that replaces a safety review.
Record observations and the remaining work.
Use a review record that identifies the requirement, result, evidence, responsible person and any follow-up. Keep incomplete checks visible when hardware, wiring, utilities or another supplier’s system is not available. Do not turn a limitation into an assumed pass.
The handover should say which project version the test refers to and what changed after it. Agree how new requests are distinguished from correction of the contracted work. If a change affects an accepted sequence or interface, define which checks need to be repeated.
List the engineering files and operating dependencies.
Specify editable PLC/HMI or SCADA projects, comments, tag lists, drawings, operation notes and backup records in the contract or scope list. File formats, software versions and any third-party restrictions matter as much as the presence of a folder named source.
Commercial runtime licences, user accounts, hosting, remote access and onsite support should be listed as distinct items where relevant. Confirm the party responsible for them and the intended maintenance handover. This guide supports a clearer engineering agreement; it is not a pre-filled acceptance certificate or a claim of regulatory compliance.
Bring your equipment into the discussion.
Use the blank checklist to describe the required behaviour, available hardware and the boundary of the work. An initial non-confidential summary is enough to start; do not include passwords or proprietary source files.
