CPU (PLC Controller)

Block diagram

Overview

Our integrated circuits and reference designs help you create efficient central processing unit (CPU) modules whether they are run by programmable logic controller (PLC) code, C code or by software on a high-level operating system. We have the ingredients to assess available performances, latencies, heat dissipation, reliability data and wiring protection.

Design requirements

CPU (PLC controller) systems often require:

  • Artificial intelligence (AI) edge processing, time-sensitive networking (TSN) and OPC Unified Architecture.
  • Scalable solutions for processing and industrial networking.
  • Functional-safety readiness, robustness and/or EMI/EMC resilience.

Self-diagnostics/monitoring

close

To ensure correct functioning of the module, it is necessary to monitor the temperature and in some cases of the humidity on the module. Depending on the internal system setup and board size, multiple sensors may be used.
