Probably , the single most important device representing factory automation is the PLC (Programmable Logic Controller). Introduced in the late 1960s, PLCs are designed for real-time processing of a large number of IO in industrial plants. What differentiates a PLC in the market is its IO capacity (identified by the number of IO and the related scan rate) and its computational performances.

As such, core devices of this level are:

  • 32-bit MCUs
  • Intelligent Power Switches
  • Current Limited Termination inputs
  • Data communication interfaces

The entire of factory automation is regulated by standards, both in the Safety and in the Communication domain, ST has established numerous partnerships over the years, enabling the implementation of state of the art ICs and solutions, these are demonstrated in our large evaluation board catalogue.
