Companies who do not carry out emulation (or virtual commissioning) can only start controls testing when the real system is at least predominantly assembled, which means they are near ramp and handover, with a large amount of unpredictable testing yet to be started, and probably onsite and under close client scrutiny. Hardly the best of conditions for carrying out the methodical task of analytical verification, debugging and repair.
The top machine builders are switching from proprietary hardware-based PLCs, like Allen-Bradley, TwinCAT, Mitsubishi and KEYENCE, to open standards-based EtherCAT-enabled software PLCs on IPCs. KINGSTAR provides a fully-featured and integrated software PLC based on an open and accessible RTOS. KINGSTAR Soft PLC also includes add-on or third-party components for motion control and machine vision that are managed by a rich user interface for C++ programmers and non-developers alike.
