Arduino OPTA PLC - Sequential Function Chart SFC

Sequential Function Chart (SFC) is a graphical programming language that can be used in Arduino Opta PLCs.  It can be used to program sequential control systems in industrial automation applications. It is a part of the IEC 61131-3 standard and is commonly used in programmable logic controllers (PLCs) and other industrial control systems. SFC allows programmers to create complex control sequences by breaking them down into small, manageable steps. It consists of interconnected steps, each containing actions, conditions, and transitions. These steps are executed in a predetermined order based on the conditions and transitions defined in the chart. SFC is particularly useful for complex, multistage control systems, such as manufacturing and process control applications.
The Arduino Opta PLC supports sequential function chart programming as one of the five programming languages in the IEC standard and Arduino C++. This lets you choose the programming language that 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.

Hi.. Have you ever tried Opta with any display to show the readings through Modbus RTU.

What means "StartButton AND StopButton"? Both values are equal to TRUE? We have Stop button like a normally closed contact?
