What is a programmable logic controller used for?
A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices.
What is a good use for a programmable logic controller?
Based on its inputs and outputs, a PLC can easily monitor and record runtime data like operating temperature, machine productivity, generation of alarms when a machine fails, automatic start and stop processes and more.
What are the advantages and disadvantages of PLC?
Advantages and disadvantages of PLC
- Rugged and designed to withstand vibrations, temperature, humidity and noise.
- PLC has a lot of contacts and low cost and safe.
- It has a very faster scan time, it has a fast operating time.
- A wide range of control application.
- It has capable to communicate with a computer in the plant.
How does a Programmable Logic Controller work?
The programmable logic controller will process the given information (inputs), execute the instruction from the program, and deliver the results (outputs) based on the provided information and written logic. PLCs operate in a repeating loop once the user determines the inputs and outputs.
Where are programmable logic controllers used?
Areas where programmable logic controllers are applied PLCs are used in various applications in industries such as the steel industry, automobile industry, chemical industry and the energy sector. The scope of PLCs dramatically increases based on the development of all the various technologies where it is applied.
