Understanding programming languages
The key component of creating a program resides in what is called a programming language. A programming language is a special language that both a computer and a machine can understand. There are many different programming languages that are available, especially for PLCs. In terms of general-purpose text-based programming languages, there are a few popular ones, which are as follows:
- Java
- C/C++
- C#
- Python
- JavaScript/Node.js
There are many more general-purpose programming languages available, these are just a few. In terms of PLC programming, there are some specific languages that can be used depending on the PLC being used, which are as follows:
- Ladder Logic
- Sequential Function Chart
- Function Block Diagram
- Structured Text
Now, having so many different programming languages may seem redundant, but each language has its own niche, strengths, and weaknesses, and many of the languages follow different...
