The Siemens 6ES7416-2XK00-0AB0 is a SIMATIC S7-400 CPU 416-2 DP central processing unit with a multi-point MPI interface and an integrated PROFIBUS DP interface. It's the brains of a mid-to-large S7-400 rack — handling logic execution, communication, and I/O mapping for processes that demand deterministic cycle times.
Lifecycle Reality for the Buyer
This CPU carries a mature lifecycle stage. Expect to source it through surplus or broker channels.
What the Interfaces Mean in Practice
The integrated MPI port handles programming and low-speed HMI communication at up to 187.5 kbps. The PROFIBUS DP interface runs at up to 12 Mbps, deterministic enough for a weld line or conveyor cell where jitter under 1 ms matters. If you're replacing a failed unit, the DP address and baud rate must match the existing network configuration — no auto-addressing here.
