At the heart of most industrial control and factory automation systems is a programmable logic controller (PLC). Commonly referred to as the „brain“ of a factory, a PLC controls a wide range of functions by receiving and processing data from sensors and machines. It then uses this data to control and actuate external devices.
Because it's used in industrial applications, a PLC must be robust. What's more, a successful design must offer reliability, system stability and 100% interoperability with connected automation systems. Additional factors to consider when engineering a PLC include time-to-market, space limitations, and the high demand for components with a good price-quality ratio.
