Arduino OPTA PLC - Structured Text ST First Program

Structured text (ST) programming is a programming language that is part of the IEC standard and is used in the Arduino Opta PLC. This programming language allows you to write code in a structured and organized manner, making it easier to understand and maintain. With structured text programming, you can create complex and sophisticated programs by combining statements, functions, and variables. Artificial intelligence (AI) can be easily used with structured text (ST). We will demonstrate how to use AI to get a sample program for quick modifications in our application. The Opta PLC provides high flexibility and control of your applications.
The Arduino Opta PLC supports structured text programming as one of the five programming languages in the IEC standard and Arduino C++. This lets you choose the programming language best suits your needs and preferences. Arduino C++ is a widely used programming language in the Arduino community and offers a vast library of functions and resources. Whether you program in structured text, Arduino C++, or any other language, the Arduino Opta PLC provides a powerful platform for developing automation and control applications. Its versatility and compatibility with different programming languages make it popular among developers and engineers.

In the following sections, we will explore how to start a new project in the Arduino Opta PLC and how to map the physical I/O in the PLC. These steps are essential for setting up the foundation of your project and ensuring proper communication between the PLC and the external devices.

Very detailed information in this video. Question: how do you define and use Timers in Structured Text programming ? Thank you.

Over the years there have been several times you upload a video and you're messing with the same thing I am, always found that to be a funny coincidence. Although its happening less now that I've moved away from Automation Direct PLCs. Have you ever messed with any Beckhoff stuff? I think you would have a lot of fun with it. The program environment is free in a way that's good for educational stuff like this and their hardware is decently priced. I switched to Beckhoff recently because of the platforms nearly endless possibilities and user friendly support.
