Question

What are programmable logic controllers used for?

Answer 1

A PLC (programmable logic controller) is a digital computer used for industrial automation to automate different elector-mechanical processes. It was introduced to eliminate issues such as high power consumption that arose from the use of relays to control manufacturing processes.

AND

Due to their advantages like

• Very fast.
• Easy to change logic i.e. flexibility.
• Reliable due to absence of moving parts.
• Low power consumption.
• Easy maintenance due to modular assembly.
• Facilities in fault finding and diagnostic.
• Capable of handling of very complicated logic operations
