Specification

The Siemens SIMATIC S7-400 CPU 417H (6ES7417-4HT14-0AB0) is a flagship high-availability controller engineered for the most demanding redundant automation scenarios. Designed to operate in a fault-tolerant configuration, this CPU delivers uninterrupted process control even during a module failure, making it the backbone of critical infrastructure in chemical, petrochemical, and power generation plants. With a powerful 30 MB memory split evenly between program and data, it handles extensive control logic and large data sets with ease. The CPU features three onboard communication interfaces: one MPI/DP port, one PROFIBUS DP port, and two dedicated slots for synchronization modules, ensuring robust and deterministic data exchange between redundant units. Below is the comprehensive technical specification table for this model.
