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 interesting. Thank you.

[@ACCautomation]

I am glad you liked it. Thanks for the comment.

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.

Hi @Fine_i_set_the_handle
I have not had the opportunity to use the Beckoff PLC. I believe that it is the TwinCat 3 software. I'll will reach out to them.
Thank you,
Garry

[@ACCautomation]

Can you recommend some hardware from Beckhoff that would be good to utilize? I am especially interested in communication with Modbus TCP and MQTT.
Thanks,
Garry

[@Fine_i_set_the_handle]

@@ACCautomation You can actually just use an old desktop or laptop you have around with twincat 3 XAE software to turn it into a temporary beckhoff PLC. It can use MQTT and Modbus TCP without any special hardware. A desktop pc with XAE software will also be compatible with their ethercat hardware (EK1100 bus couplers and relevant IO cards). I bought some Ek1100(field coupler) el1809(16 digital input) and el2809(16 digital output) cards off ebay for a few hundred to play with a year or so ago and had a blast.
