CP701 S1 Yokogawa | CENTUM CS/VP Processor CPU Module

Yokogawa CP701 S1 CENTUM CS/VP Field Control CPU Module

The CP701 S1 (Model: CP701 S1) is a high-integrity processing unit serving as the core of the Field Control Station (FCS) within Yokogawa’s CENTUM CS 1000, CS 3000, and CENTUM VP Distributed Control Systems. Powered by the specialized R4300 RISC microprocessor, this CPU manages complex regulatory control and high-speed logic sequences. The CP701 S1 is engineered to provide a stable, deterministic environment for process automation, featuring Error Correction Code (ECC) memory to prevent system crashes caused by soft memory errors, which is critical for 24/7 industrial operations.
