A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines.

PLC-based control systems began to function like a mini-DCS. At the same time, the DCS hybridized to incorporate PLCs and PCs to control certain functions and to provide reporting services. The DCS ...

All automated systems are built with a PLC or PAC to control individual machines or stations. Additionally, the computers can be programmed to control a group of machines or stations.

The most detailed response explained that: an RTU is a “microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA system by ...

The programmable logic controller (PLC) is an important component in most modern automation and process control systems today. It's also susceptible to lightning-induced transients. To verify the ...
