What are the advantages of PLC over relay logic?

  • Ability to interface / communicate with computers.
  • Simple programming.
  • High reliability.
  • Easy maintenance.
  • Rugged construction – can operate in extremely harsh conditions.
  • Small size.
  • Easy expandability.
  • Economical in long term.

What are the advantages of PLC Mcq?

Higher Reliability: Once the program 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.

What is meant by a PLC and why is it used list its advantages?

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. Another advantage of a PLC system is that it is modular.

What is a programmable logic controller PLC )? List six distinct advantages that PLCs offer over conventional relay based control systems?

List six distinct advantages that PLCs offer over conventional relay-based control systems. Reliability, flexibility, lower cost, communication capability, faster response time, easier to trouble shoot.

What are the advantages of PLC compared with mechanical relays and delays?

PLCs are much more reliable and are way easier to troubleshoot. The mechanical functions of relays simply wear out over time. Plus, the wiring required to operate a relay system is much more complicated than a PLC system. This can also cause higher costs to install and upgrade due to extra labor costs.

What is programmable automation Mcq?

Programmable automation allows for machine configurations and operation sequences that can change based on signals sent from electronic controls. (b) With a programmable automation system, products can be produced in batches through the reprogramming of machine operations and sequences.
