CPUs
Industrial PLC CPUs are the processing and execution core of your automation architectures.
Dedicated to complex applications and high-speed processes, such as the Siemens SIMATIC S7-400 range, they centralise program management, I/O data processing and fieldbus communication.
Discover our certified, refurbished or overhauled CPUs to ensure operational continuity and maintenance of your production lines.

FAQ
This CPU is designed for demanding processes requiring large working memory, high processing speed and outstanding reliability. It has built-in communication interfaces (PROFIBUS DP, MPI) to coordinate a large number of networked I/O cards and peripherals.
A faulty CPU typically shows a red SF (system fault) or BF (bus fault) LED, stays in STOP mode or keeps restarting, loses its program or retentive memory, or stops communicating with the programming software and the I/O modules on the bus.
Yes, component-level electronic repair restores faulty CPUs (repair of internal power supply boards, replacement of communication bus chips, memory repair). This avoids a complete migration to a new PLC range, which is often lengthy and very expensive.
Every refurbished processor is mounted in a dedicated test rack and put through full load cycles, network communication tests (PROFIBUS/MPI) and memory backup checks to ensure immediate, risk-free reintegration into your electrical cabinet.
