Open PLCs: Unlocking the Power of Industrial Automation

Learn about the new concept of open PLC technology.

Programmable Logic Controllers (PLCs) have been the backbone of control systems for a long time.

However, traditional PLCs have been known for their close architecture which results in limited flexibility in programming and also integrations with other systems. This is where open PLCs come into play.

An open PLC is based on the Linux operating system and because of that, it can be programmed using higher-level programming languages such as C++, Python, and Java.

Using an open PLC you can write different programs in different programming languages. These programs can then run independently on the same PLC.

PLCnext Technology: An example of Open PLC

PLCnext technology is an example of an open PLC. Since this PLC uses Linux as its operating system, you can program it using different programming languages (both high-level and low-level).

One of the most important aspects of open PLCs is the fact that they use a global data space. This global data space allows for different programs to communicate with each other and exchange process data.

For example, you can have both a ladder logic program and a C++ program on PLCnext, and these two programs can exchange data with each other easily, something that was previously close to impossible with traditional PLCs.

This flexibility of open PLCs allows engineers to use the language they are most proficient in and that best suits the requirements of their specific application. This can lead to more efficient and effective programming.

Another advantage of utilizing a global data space for an open PLC is having a more seamless integration with other systems such as Fieldbus or other devices. This is because of the easy data exchange between different programs.

Available resources for your learning journey

If you are interested in exploring the exciting world of open PLC programming, I suggest starting by signing up for the PLCnext Starterkit Configuration and Programming Basics course.

Once you complete this course and if you are RealPars Pro Member you can continue with the PLCnext Ladder Logic Programming course and then the Using C++ Projects with PLCnext Technology course right after.

You’ll receive a certificate upon completing your training, signed by Phoenix Contract!

5 Actionable Tips for Getting a PLC Programming Job with NO Experience

In this blog post, you’ll learn about the mindset that helped me getting a PLC programming job with NO experience. This is my personal experience as someone who searched for a job in this field and as an employer who reviews resumes and interviews candidates for a variety of projects. So let’s get started!

What is an Open PLC?

What is an Open PLC?

To program a PLC, I need to write a program on my computer and download it to the PLC. To be able to write the program on my computer, I need programming software, right? I can not just open up my laptop and start writing codes. For example, to write code in C++ on my...
