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 control unit also enables connectivity to various fieldbuses including PROFIBUS, Modbus and CAN open, industrial Ethernet such as Profinet, EtherCAT, wireless technologies and to the backplane bus of the system.

ST provides wired connectivity solutions for PLCs, including RS-232, RS-485 & CAN, as well as wireless solutions implementing Bluetooth Low Energy and LoRa technologies. A wide range of DC-DC switching converters and linear voltage regulators, protection devices and high-performance STM32 microcontrollers and microprocessors are also available.
