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.
Fieldbus and Industrial Ethernet
In factory automation, data connectivity is essential, especially now with the Industry 4.0 concept widening its scope. A number of standards are used to support specifically developed fieldbuses including the classic CAN (Modbus and CANopen), RS-485
View application Human Machine Interface
To help us effectively control equipment as well as make decisions based on machine feedback, we use a Human Machine Interface (HMI) which can be a simple display directly assembled on a machine for factory automation or multi-touch display panels fo
View application Input/Output Modules
Input/Output (I/O) modules collect data from input devices including proximity, pressure, temperature sensors and push buttons, and control actuators such as valves, relays and lamps (output devices). These modules can either be added to a Programma
View application IO-Link Modules
Paving the way to Industry 4.0, IO-Link communication networks (IEC 61131-9) can be used for bi-directional, point-to-point data connectivity down to the actuator and sensor level, enabling data pre-processing, sensor parameter tuning and advanced di
View application PLC Control Unit
The PLC Control Unit in a Programmable Logic Controller (PLC) is the main building block which processes data coming from input devices and controls outputs. It can be integrated with I/O modules to provide the required functionalities. The PLC contr
