In a 24/7 plant the SCADA screen at shift change looks calm, but it hides a lot. A trip is bypassed for a valve job, three alarms are shelved, a control loop has been in manual since midnight and one remote PLC keeps losing its link. None of that is obvious to the operator walking in. A digital SCADA handover checklist makes sure every hidden condition is explained and accepted before the outgoing operator leaves. This guide gives the full checklist plus the KPIs, data and risks behind it. Review yours in a handover session.
Digital SCADA Handover Checklist for 24/7 Manufacturing
Eight sections, thirty-five checks, built around what the SCADA does not show at a glance: shelved alarms, bypasses, forces, manual loops and data faults. Use it on paper today, or let AI fill it from live SCADA data.

Why SCADA Handover Needs Its Own Checklist
The screen shows the process. It does not show what people did to it.
A general shift handover covers people, jobs and safety. A SCADA handover has to cover something more: the changes operators and engineers made to the control system itself. Shelved alarms are silent. Bypasses and forces hide behind normal-looking graphics. A loop in manual looks fine until the process moves. HSE guidance on shift handover lists maintenance across a shift change, overridden safety systems and deviations from normal working among the handovers that carry the most risk, and all three show up directly in SCADA. Our automation team can help you map them in your plant.
Silent alarms
Shelved and out-of-service alarms make no sound for the new shift.
Hidden bypasses
A bypassed trip looks the same as a healthy one on most screens.
Manual loops
Loops left in manual will not respond when conditions change.
Bad data
Stale or frozen values look like real readings.
The ISA-18.2 alarm management standard separates alarms that are shelved by an operator, suppressed by design and taken out of service for maintenance. Each one is a deliberate decision to stop an alarm sounding. A good handover lists every one, with who made the decision and when it ends.
The Digital SCADA Handover Checklist
Tick each item as you go. The tally at the end of each section counts your ticks.
Work through the sections in order with the incoming operator beside you. Sections 03 and 04 are the ones most often skipped and the ones that matter most. If you want this checklist pre-filled from your SCADA, talk to our implementation team.
Plant state and production
Start with the big picture so the incoming operator knows what normal looks like right now.
Active and standing alarms
Alarms that are live at the change are the first thing the next operator will see, so explain them.
Shelved, suppressed and out-of-service alarms
These alarms are silent on purpose, which is exactly why they must be handed over.
Overrides, bypasses and forces
A bypassed trip or a forced output is the most dangerous thing to forget at a shift change.
Control loops and setpoints
The next operator needs to know which loops are not doing what the design expects.
SCADA, network and data health
If the screens or the data cannot be trusted, the next shift needs to know before acting on them.
Maintenance, permits and isolations
Work in the field changes what the SCADA screen means, so tie the two together.
Sign-off
A handover is only finished when the incoming operator says so.
Let SCADA Fill the Checklist for You
Alarm counts, shelved alarms, bypasses, manual loops and comms faults read straight from the control system, so operators spend handover time explaining, not counting.
Data a Digital Handover Needs
Most of the checklist already exists somewhere in your systems.
A digital handover pulls each checklist section from the system that already holds it. That cuts typing and makes the record more accurate than memory. The grid below shows where each section usually comes from. Ask our integration team what your systems can provide.
KPIs for SCADA Handover Quality
Measure the handover, not just whether it happened.
A signed handover log only proves a handover took place. These measures show whether it carried the right information. Track them weekly by control room and shift. Set your baseline in a KPI workshop.
Checklist completion
Share of handovers with every section completed and accepted by name.
Bypass match rate
Bypasses on the handover compared with bypasses in the system at that moment.
Shelved alarm age
How long alarms stay shelved, and how many pass their planned return time.
Handover-linked events
Incidents or near misses where missing handover information played a part.
Paper Log Versus Digital Handover
Same checklist, very different reliability.
Many plants already have a good checklist on paper. The problem is that it relies on the outgoing operator remembering and writing everything at the end of a long shift. A digital handover reads what it can from the systems and asks the operator only for what a person must explain. Discuss the move with our support desk.
Paper or spreadsheet log
- Counts and lists written from memory
- Easy to skip shelved alarms and forces
- Hard to search across weeks
- No check against the live system
Digital SCADA handover
- Counts and lists read from SCADA
- Every bypass and shelve listed automatically
- Searchable by unit, tag and date
- Gaps flagged before sign-off
Handover Risks and Mistakes to Avoid
The checklist helps only if it is used honestly.
Checklists fail when they become a box-ticking exercise at the end of a shift. These are the most common problems in control rooms. A short handover audit can spot them.
What works
- Walking the screens together
- Bypasses and shelves always covered
- Return times on every silent alarm
- Named acceptance by the incoming operator
What fails
- Ticking every box without checking
- Handover done by message, no talk
- Bypass register kept apart from the log
- Rushing in the last five minutes
How iFactory Runs Digital SCADA Handover
AI digital logbook, connected to SCADA, on your own network.
iFactory reads your SCADA, alarm server, historian, permit system and CMMS on an on-prem AI server inside your plant. It pre-fills the handover checklist, flags anything missing an owner or end time, and records named acceptance. Fit questions go to our solutions team.
Pre-filled checklist
Counts and lists read from live SCADA.
Silent alarm tracking
Shelved, suppressed and out-of-service alarms listed.
Bypass and force register
Every override carried across shifts.
Data health
Comms faults, bad tags and historian gaps.
Voice notes
Operators explain items by voice.
Named acceptance
Incoming operator signs off in the log.
Results depend on your SCADA platform, alarm system and handover habits. We measure checklist completion, bypass match rate and shelved alarm age on your own data during the pilot, rather than promising a general figure.

Frequently Asked Questions
What is a SCADA handover checklist?
It is a structured list the outgoing control room operator works through with the incoming operator. It covers plant state, alarms, shelved alarms, bypasses, loops, system health, permits and sign-off.
How is it different from a general shift handover?
It focuses on the state of the control system itself, including changes that are hard to see on screen, such as shelved alarms, forced I/O and loops in manual.
Which items matter most?
Bypasses, forces and silent alarms. They can leave the plant less protected than it looks, and the incoming operator has no way to see them without being told.
Can the checklist be filled automatically?
Much of it can. Alarm states, loop modes, comms faults and open permits can be read from your systems. Operators add the reasons and context.
Does it work with our SCADA platform?
Most SCADA and alarm systems can share data through standard interfaces such as OPC UA. We confirm your platform during scoping.
Does digital handover replace talking?
No. Safety guidance favours face-to-face handover backed by a written record. The digital checklist gives the record and frees time for the talk.
How long should a SCADA handover take?
Long enough to walk the screens together and answer questions. With counts and lists pre-filled, most of the time goes on explaining bypasses, silent alarms and open work rather than writing them down.
Where is handover data stored?
On the on-prem server in your plant, searchable by control room, unit, tag and date.
How do we start?
Start with one control room. A 6-week pilot connects your SCADA, tunes the checklist and runs digital handover beside your current log. To plan it, contact our team.
