You should know the advantages and disadvantages of PLC (programmable logic controller) before buying it

Navigasi - Currently, almost all lines of life must use electricity, including manufacturing companies which are highly dependent on industrial machines.

You should know the advantages and disadvantages of PLC (programmable logic controller) before buying it


It is certain that every industrial machine needs electricity to operate, be it a household industrial machine or a large-scale industrial machine, as we know that Sanya's industrial machine requires an electrical control system to operate it.

While the electrical control system requires many components (spare parts) such as contactors, timers, relays, counters and so on.

This makes the components (spare parts) crowded the electrical panels that we use to solve these problems, one of which can use PLC.

PLC is an abbreviation of English, namely programmable logic controller if interpreted in Indonesian is programmable logic control.

With PLC you can create electrical control systems using the principles of the wiring system as the basis for programming logic.

PLCs themselves have many advantages, although there are definitely disadvantages, so we summarize them as follows.

Advantages and disadvantages of PLC (programmable logic controller)


Advantages of PLC (programmable logic controller)


PLC Makes it easier to find problems with industrial machine electrical system damage

As we know that Sanya PLC can reduce many components ( spare parts ) used in the electrical control system of industrial machines .

This makes the number of cables used automatically reduce which makes it easier for us to search for damage to electrical components in these industrial machines.

In addition, the PLC also has an indicator light for the electric current that enters the PLC slot, plus if you have a laptop you can directly monitor from the laptop monitor which electrical lines are damaged or disconnected on the machine.

PLC can reduce the cost of purchasing electrical spare parts (components)


If industrial machines use PLC it will reduce a lot of the cost of purchasing cables and also reduce the cost of purchasing electrical spare parts such as contractors, timers, counters, relays and so on.

If we calculate from an economical point of view, using a PLC is much cheaper than using an analog electrical control system (conventional) which costs a lot to purchase cables and electrical components.

The number of slots (contacts) is more


There are more slots or PLC contacts compared to contactors or relays, which have a small number of slots.

In addition, each slot (contact) can be programmed into various electrical components that you want.

PLC is easy to reprogram and easy to repair


PLC is easy to make a new program if the previous program has an electrical circuit error because you only need to check the circuit through the laptop monitor.

It's different if you still use electrical circuits in conventional systems which require a lot of time to repair.

In addition, if you use a PLC for making the program it is not too long and not too complicated because it is enough to use a laptop and in a matter of minutes a new program can be completed and has been reinstalled with a new circuit system program.

PLC can be installed with various electrical circuit systems


The use of PLCs is not limited to just one electrical circuit because you can install PLCs with various variations of electrical circuits.

This is one of the plus points that PLCs have, if there is a new circuit, you can test and install it directly to try to use it.

PLC can simplify electrical circuits and is easy to clean


With PLC you can make electrical circuits simpler and simpler because PLCs can reduce the use of electrical spare parts (components) as we know that too many electrical components will make it difficult for us to check and repair.

In addition, the use of cables is also reduced so that for aesthetics the tidiness of electrical circuits is easy to make, unlike using conventional systems that use many cables so that it is sometimes difficult to tidy them up.

PLC security is more guaranteed


With a PLC you can test it without having to turn on 3 phase electricity because there are several conventional circuits that force you to turn on 3 phase electricity.

If you use a PLC, just check it on the laptop monitor, otherwise you can lock it so that no one can access, change or even steal the circuit.

PLC Interface Makes it easier for us to create new circuits


With a PLC interface that we can monitor on a computer monitor (PC) or laptop before we apply it to the machine.

This makes it easier for us to design an electrical circuit that is simpler than the previous circuit because we can check for electrical circuit errors without having to apply it.

PLC easy to make documentation


With a PLC you can easily print a series of machines in just a matter of minutes.

It's different from conventional systems where you will find it difficult to document engine control circuits.

This makes it easier for us to record every series of machines that we have.

Can monitor damage remotely


For the latest version, several PLCs have been provided with a wireless system, making it easier for us to access it anywhere, we don't have to arrive at the location to monitor the damage to the electrical control circuit.

Disadvantages of PLC (programmable logic controller)


Of the various advantages above, there must also be disadvantages, so we have summarized them from various sources as follows.

Experts who can operate PLC are rare


Because PLC is one of the newest technologies, finding people who are able to program and apply it to machines is rare.

So you have to be selective about the difficulty in finding experts who master PLC.

PLC is not strong in a certain temperature environment


An environment that is too hot can cause the PLC to be damaged or error, besides that the temperature is too humid, it can also trigger an electrical short circuit in the PLC.

So to apply PLC we must first see the condition of laying industrial machines.
