Programmable logic controller (PLC)

Programmable logic controller (PLC) is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability and ease of programming.  PLCs can be programmed in ladder logic or other programming languages. Rugged enough to handle extreme environments, a programmable logic controller (PLC) is an industrial computer that has been adapted for the control of manufacturing processes. PLCs may be programmed and reprogrammed to respond to changing conditions in the process. They are used to perform such tasks as controlling machine movement and counting products gathered on assembly lines; managing robotic devices; detecting product defects during manufacture, and keeping an account of inventory for billing purposes.
