C6 Safety PLC

Thanks to the flexible software architecture in which safety functions are an integral part of the user software, different safety functions can be freely programmed in the Safety PLC of KEB using the standardised languages of IEC 61131-3 (CODESYS). The architecture of the Safety PLC is prepared for certification to the highest safety standards (SIL 3 to IEC 61508, PLe to DIN EN ISO 13849).

By design, the safety controller is adapted to the real-time environment of EtherCAT and can be expanded universally in conjunction with KEB’s modular I/O system. The decentralised structure is designed for direct installation in machines and plants without additional wiring complexity - and at the same time with little space requirement and rapid installation. For the user, the Safety PLC meets all the conditions for implementing a safety concept without further certification expense. This includes the possibility of equipping existing plants with modern safety functions in a short time.


  • Freely programmable Safety PLC (IEC 61508 SIL3 and DIN EN ISO 13849-1 Ple)
  • Certified safety function modules
  • Substantial reduction in time spent in development, verification and testing of a safety application
  • Programming by means of CODESYS Safety by main controller and EtherCAT® connection
