Multi-level approach to virtual commissioning: a reconfigurable assembly system case

Software plays a key role in modern automated systems. Testing the control software is one of final steps development process and when done on physical set up, it creates risks (e.g. project delay, system damage operator injury). In addition, with flexible systems almost impossible to test every possible scenario real system. Using digital model allows testing different configurations before hardware available thus without risk for hardware. A reconfigurable can also help validate new virtually while still operates its current configuration, allowing quick risk-less changeover. Depending level hierarchy, simulations run faster than time. This paper demonstrates use during commissioning at levels. On each level, other requirements need be fulfilled detail needed model. Every asks input data, that needs consistent result reliable emulation/simulation. The methodology evaluated assembly system, consisting multiple base units modular, relocatable add-on modules. most detailed machine considering low-level logic, movements robots, collisions, etc. Cell plant focuses interaction machines, transport, production schedule assignment tasks individual machines. typically covers longer time span requires less actions level. It interacts higher simplified version logic implemented itself. describes lessons learned reuse levels hierarchy remaining consistency by exchange information within Further research described towards virtual case scenarios
