At the same time, the long-term efficiency and flexibility of the systems are increased – thanks to common, open industry standards. The KR C4 software architecture integrates Robot Control, PLC Control, Motion Control (for example KUKA.CNC) and Safety Control. All controllers share a database and infrastructure. With five variants(KR C4 compact, KR C4 smallsiza-2, KR C4, KR C4 midsize and KR C4 extened), the KR C4 can be optimally integrated into your automation environment. Requirements for stackability, protection against dust, humidity and other influences can thus be taken into account."
