In this video, Zahraa Khalil overviews what PLC is and gives an introduction to the concept by exploring the areas where PLC is usually used.
- [Instructor] Programmable logic controllers, PLC. PLC is an acronym for programmable logic controller. PLC is an industrial computer control system which controls devices by continuously monitoring the state of input devices and makes decisions based on a logic program to control the state of an output device. Incoming control signal is called an input. A signal going out of the PLC to control a field device is an output.
PLC is a special form of microprocessor base controller that uses programmable memory to store instruction to control machines and processes, sends, receives, and processes data from and to the field devices. PLC monitors discrete things. It has a high speed response, so usually they're used in applications where high speed response is required, like manufacturing processes, industrial applications, and some traffic systems.
Basically any application that needs a regulation of an input and an output.
Learn about the components and networks involved at each level of automation: field level, control level, and management level. Explore the different devices involved, from the programmable logic controllers (PLCs) on the factory floor, to OPC software that give technicians insights into operations. Instructor Zahraa Khalil, an engineer and educator, also provides an overview of SCADA (supervisory control and data acquisition), an industrial control system architecture that enables supervision over large distances and multiple sites.
