Programmable logic controllers (PLC) gather and process data from sensors and control actuators. They could be defined as highly integrated industrial computers, with real-time capabilities, an isolated power supply, analog and digital inputs and outputs (I/O), communication interfaces for fieldbus or real-time Ethernet links to connect various sensors and actuators.
Designed to be robust, multi-application and configurable, programmable logic controllers must be well protected against electrostatic discharge (ESD) and electromagnetic interference (EMI). They are often separated into several different modules: the PLC control unit containing the main processing unit and the various modules with the distributed functions and interfaces.
Reliability, long-term availability, safety and security are challenges for any PLC design and we have an extensive offer of STM32 32-bit microcontrollers, EEPROM, protection devices, transceivers for fieldbus and IO-Link connectivity, intelligent power switches and drivers for outputs.
We also help designers of programmable logic controllers with a large ecosystem of hardware and software evaluation and development tools.
