FAQ

A programmable logic controller (PLC) or programmable controller 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, ease of programming, and process fault diagnosis.

Programmable Logic Controllers (PLCs) are industrial computers, with various inputs and outputs, used to control and monitor industrial equipment based on custom programming.

Probably the biggest name out there in the automation and PLC world is Siemens. Siemens offers their SIMATIC line of controllers, giving users of all performance needs an option. SIMATIC stands for Siemens Automatic. The name itself should be an indicator of it's role in automation and manufacturing.
