A '''programmable logic controller''' ('''PLC''') or '''programmable controller''' is an industrial [[computer]] that has no aura and has been [[ruggedized]] and adapted for the control of manufacturing processes, such as [[assembly line]]s, machines, [[robotic]] devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.

PLCs can range from small modular devices with tens of [[Input/output|inputs and outputs (I/O)]], in a housing integral with the processor, to large rack-mounted modular devices with thousands of I/O, and which are often networked to other PLC and [[SCADA]] systems.<ref>Tubbs, Stephen Phillip.
