Before Wunderlich–Malec delivers a process control system to a site, we complete a Factory Acceptance Test (FAT) and/or an Operator Acceptance Test (OAT), which is witnessed by the customer and the end user. The FAT/OAT is an integral part of Wunderlich–Malec’s project methodology; it demonstrates that:

• the hardware and software work according to specification
• network communications and interfaces function properly
• the application program satisfies the design requirements and works within the hardware
• support and interface systems perform as specified
• hardware and bills of material are complete
• system integration is complete
• the graphical interface presents data as expected

Wunderlich-Malec uses external software to simulate all real-world inputs. This software is configured to provide normal feedback, such that all devices can be tested at both the template level and the sequence level. Each individual fault is then tested, and the reaction of the programmed logic is verified to operate per the sequence of operations. This detailed level of simulation ensures that when a control system is brought to the field for start-up commissioning, the software has already been verified and the sole focus of commissioning is to check out field devices and wiring.

An added benefit of this level of simulation is that the bench test system can be used to provide operator training on the system, significantly increasing your operations efficiency during startup and production.
