Factory Acceptance Testing (FAT) is one of the most important milestones in our system integration delivery process. It’s where we prove the solution performs as designed, before it ships to site, helping reduce risk, avoid rework and supports a smoother commissioning and startup.
A comprehensive FAT is the final line of defence before deployment. Our engineers rigorously validate hardware and software against the project requirements, using realistic simulation and structured test procedures to ensure the system is ready for the next phase of delivery.
Why FAT matters:
✅ Identify design gaps, logic issues and hardware faults early (when they’re cheaper to fix)
✅ Reduce commissioning time and minimise site disruption
✅ Validate PLC, HMI and SCADA functionality under real-time simulation
✅ Confirm alarms, interlocks and sequence behaviour before deployment
✅ Reduce avoidable travel, troubleshooting time and rework
✅ Provide clear, traceable test records and digital documentation
✅ Give stakeholders confidence through transparent, witnessed testing
✅ It’s a great opportunity for stakeholders to train on and be familiar with the new logic and SCADA displays
What we verify before equipment leaves our workshop:
• Hardware integrity: Panel build quality, I/O mapping and device verification
• Software logic: Code validation against project requirements and functional descriptions
• Communications: End-to-end connectivity (e.g. Modbus, Profinet, Ethernet/IP and related networks)
• Functional performance: Alarms, permissives, interlocks and sequence simulation
At Motherwell Automation, we don’t just build systems, we validate them. Thorough testing upfront helps deliver a cleaner install, fewer surprises onsite and a more predictable startup.
