Differences between Industrial PC and PLC for Educational PLC Courses

If you are a programmer that wants to work in the automated industry, it is essential to understand the differences between PLC and industrial PCs.

The debate on which one is the best is consistent, and according to most programmers, PLC is the better solution because it uses ladder logic, which is one of the most original programming languages that use graphical perspective.

Of course, everything depends on why you would use them in the first place. For instance, if you want to work in industrial applications or machine control, you can visit https://onlineplcsupport.com/. But before that we recommend you to stay with us to see which one is the best for various purposes.


Everything depends on which language you are most familiar with. Of course, when we compare industrial PCs with PLCs, we can say that PCs require different textual programming languages that most people are familiar with, while on the other hand, PLC uses ladder logic, which brings familiarity to most engineers.

Therefore, we cannot differentiate which one is the best because it depends on the programmer and his skill set and comfort.

Application Needs

The next question you should ask yourself is, what scope of application you wish to implement within the equipment

If the primaryintention that you wish to achieve is to create fully automate a process that features limited user input,and without advanced interface as well as data reporting and collection, then you should choose PLC.

On the other hand, industrial PC is an excellent option if the machine operation and application are beyond process control. Some examples of why you need industrial PC are:

  • If you want to link the machine to external systems such as ERP, or enterprise resource planning, or BAS, building automation system, for data analysis, reporting,and
  • If you want to make the intensive calculation that you wish to perform locally, then industrial PC is a better choice
  • If you’re going to use high-end user interface that you have to stay within the process control both remotely and locally.


The question is whether the programmer is the person who will improve and maintain software for future needs. If that is the case, the programmer should choose the appropriate programming language that he/she knows and feels comfortable with.

On the other hand, if someone else such as technician shouldconsider maintenance and troubleshooting the program code, it is essential to choose a programming language that everyone knows within your industry.

On most shop floors, technicians understand ladder logic programming, while they have less knowledge on textual languages, which means that answer is simple.You should click here if you want to learn more information on this particular idea.


You should have in mind that PLCs are more affordable solutions when compared with industrial PC and you will gain a wide array of choices when it comes to finding appropriate PLC for the budget-friendly price tag.

Operating System and Its Stability

The idea for an automated system is to get a machine that will run 24/7 without any additional problem.

Therefore, you should avoid using operating systems such as Windows, because it is not suitable for the task. On the other hand, there is not a right answer to this particular question because it depends on numerous factors within your industry.

Machine Flexibility

The main idea of using the machine in the electronic industry is to find a flexible solution for your needs. It has to be able to handle various products simultaneously at different speeds,and everything has to follow complex motion profiles.

The PLC is a robust solution that will help you with a wide array of processes such as labeling, weight control,and filling. It will help you process multiple signals with minimum code, and provide you fast response time for essential math functions.

The best thing about it is that it does not feature moving parts so that everything can withstand millions of cycles as well as the harsh environment. The main reason for PLC’s flexibility comes due to its ability to work with numerous devices at minimal costs. That way, it will expand your industry’s functionality as well as capabilities.

On the other hand, industrial PC requires additional components that you have to install even for the most straightforward functions. It includes analog, discrete and input/output cards, as well as other types of peripheral devices.

When we compare it with PLC, the integration of visual system is something that PLC does not have the same way as industrial PC, but when you have in mind that you have to pay a small fortune to get it, you probably know the answer.

Apart from that, industrial PC requires constant attention, expertise,and care to maintain the operative state, which means that you have to test it repeatedly. Many control and process engineer have stated that it is challenging and time-consuming to improve drivers for industrial PC.

On the other hand, PLCs feature reduced machine downtime, because it comes with built-in functions such as early-failure detection subroutines and backup programs. When it comes to PLC, the programming environment is consistent, concise and transparent.

Since it uses graphical method for the control and development of behavior called ladder logic, you will be able to program it with efficiency. Everything happens due to the graphical perspective that resemblesan electrical circuit, and that will emulate all operation that machine does.

PLC will offer you even more because it features different program foundation and common logic of the manufacturer. Industrial PCs do not follow the recognized standard, which means that it is challenging to decrypt actual logic.


PLCs will also offer you built-in PID functionality that will provide you accurate control of automated mechanisms that control various routines.

Most common programming languages for the programmable logic controller are functional block diagram, instruction list, structured text, and sequential function chart and ladder logic.

You will be able to learn more about them from different educational courses that will help you achieve the perfect perspective so that you can become expert in any electronic industry. It is simple as that.
