Programmable Logic Controllers (PLCs) | Applications

Programmable Logic Controllers (PLCs) Programmable Logic Controllers (PLCs) are the microprocessor controller devices situated at the remote sites of the plant or at the field of the process systems. PLCs purpose is to monitor the process parameters located at the field and adjust the outputs based on the inputs received by the PLCs. PLCs will … Read more

Advantages of PLCs

Advantages of PLCs 1. Higher Reliability Once the program was written and tested it can be easily downloaded into other PLC’s memory. It requires lesser and simpler wiring compared to conventional hard-wired circuits employed. Hence reliability of the system increases significantly with PLCs. 2. More Flexibility It is easier to create a new program module … Read more

Difference Between PLCs and Computers

Programmable Logic Controllers (PLCs) have basic architecture compared to normal general purpose computers. A normal computer can be converted to PLCs by providing a way that the computer can able to receive information or signal from the field devices such as push buttons, switches and valve positions. The computer requires some software to process the information … Read more
