The KEB C6 COMPACT II is a compact, high-performance embedded controller designed for real-time automation and motion control applications. It operates without a superimposed operating system, dedicating all its computing power to Soft-PLC and motion tasks. Powered by a 32-bit RISC microcontroller with an integrated floating-point unit (FPU), it delivers fast cycle times and deterministic real-time performance. The controller serves as a complete system controller or can be deployed as a subordinate device within a larger automation network.
