Hi there, the IOT2000 I/O module (6ES7647-0KA01-0AA2) has no basis for loading code on it. Also with the IOT2000, Arduino sketches were run directly on the Linux system. Therefore, your current code must also run on the IOT2050. You can still use the IOT2000 I/O module on the IOT2050 as usual. Converting an Arduino sketch to "normal" C code for a platform like the IOT2050 requires understanding both the Arduino environment and the target environment. Here's a simplified guide: Understand the Differences: Arduino sketches hide a lot of details. Typically, an Arduino sketch consists of two main functions: setup() and loop(). In regular C code, especially for embedded systems, the structure will often involve initializing hardware, setting up main loops, configuring peripherals, etc. Arduino provides a rich set of libraries, which may not be available on any other target platform. A IOT2050 runs a full-fledged OS (like the example image) and allows for execution of standard C/C++ programs. Begin with the main() Function: Create a new C file (e.g., main.c) and start with the standard structure:
Replace Arduino’s setup() and loop(): Place the contents of the setup() function from the Arduino sketch into the initialization section of the main() function and place the contents of the loop() function from the Arduino sketch into the while(1) loop of the main() function. Replace Arduino-specific Functions: Functions like digitalWrite(), analogRead(), etc., are Arduino-specific.They need to be replaced by equivalent functions for the SIMATIC IOT2050. Please take a look at the MRAA Library, the IOT2050 primary library for accessing the I/O’s Include Necessary Libraries: Depending on the functionality of your Arduino sketch, you might be using Arduino-only libraries. These will need to be replaced by equivalent libraries available for the IOT2050. Consider Timing: Functions like delay() in Arduino are straightforward but might not behave the same way on another platform, especially if there's an underlying operating system. Consider using more accurate timing mechanisms of C. Compile and Test: Use the appropriate compiler and tools for the IOT2050 to compile your code. The IOT2050 comes with gcc pre-installed:
