What are the pros and cons of automation?


What are the advantages and disadvantages of using PLC on machineries on board ship?

What are the advantages & disadvantages of PLC?Small physical size & shorter project time.Cost effective for controlling complex system.Reliability.Less and simple wiring.Faster response.Remote control capability.More flexibility.Ease of maintenance / troubleshooting.

What is the basic of PLC?

Basic PLC operation. The basic elements of a PLC include input modules or points, a Central Processing Unit (CPU), output modules or points, and a programming device. … The CPU evaluates the status of inputs, outputs, and other variables as it executes a stored program.

What is the advantage of using a modular PLC instead of a fixed PLC?

Modular PLCs have far more memory and has the capability to store a higher volume of information. The fixed PLC has limited I/O modules thus limiting its performance. The modular PLC has the capacity to accomplish more complex processes making it more advantageous.

What is the main purpose of PLC?

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 are the three types of PLC?

PLC are divided into three types based on output namely Relay output, Transistor output, and Triac Output PLC. The relay output type is best suited for both AC and DC output devices. Transistor output type PLC uses switching operations and used inside microprocessors.

What is the difference between a fixed PLC system and a modular PLC system?

A “fixed” PLC system would be one that’s supplied complete and cannot be changed/upgraded. A modular PLC system (which is most of them, really) is made in parts that can be swapped out, upgraded individually, removed or replaced with different parts.

What is the difference between PLC and Arduino?

PLC and Arduino are different yet can be understand as the same thing for different purpose of use. PLCs are more familiar with electrical engineers whereas Arduino with ECE engineers. PLC is a chip which is developed by few industries such as Seimens, Fuzi etc) and Arduino is a open source platform.

Why PLC is used instead of microcontroller?

The reason behind why PLC is used instead of microcontroller in industries is based on its hardware and software. … Microcontroller , on a longer run might misbehave due to the heat produced from it and also the hazardous industrial environment. But PLC have made in a way to withstand all these conitions.

What is a disadvantage of automation?

Other disadvantages of automated equipment include the high capital expenditure required to invest in automation (an automated system can cost millions of dollars to design, fabricate, and install), a higher level of maintenance needed than with a manually operated machine, and a generally lower degree of flexibility …

What is the main advantage of PLC automation?

PLC(Programmable Logic Controllers) Correcting errors in PLC is extremely short and cost effective. Space Efficient: Today’s Programmable Logic Control memory is getting bigger and bigger this means that we can generate more and more contacts, coils, timers, sequencers, counters and so on.

What are the disadvantages of PLC?

DisadvantagesOriginal owners lose control and ownership of the business.Professional directors and manager appointed to run the business may have different aims to those of the shareholders.Must disclose all main accounts to the public. … Company can be taken over if a majority of shareholders agree to bid.

Is learning PLC hard?

Someone with a good bit of programming experience will probably find the process easier than someone with little to no experience. On average, the expectation is that usually within a week or so one should be able to grasp the basics of PLC programming no matter what language is used.

Which type of controller is used in PLC?

A PLC is s general purpose controller. Often these are used in mechanized automation, but it very broad in application. PID usually refers to a form of closed-loop control; named for the terms Proportional, Integral and Derivative. PID controllers are often used in temperature control.

What are the advantages of PLC over relays?

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 are the advantages of PLC?

PLCs have the following advantages:Ease of programming in the plant.High reliability and minimal maintenance.Small physical size.Ability to communicate with computer systems in the plant.Moderate to low initial investment cost.Available in modular designs.
