How is the debugging process done in CoDeSys?

Hi friends,

CoDeSys software offers comprehensive debugging features to help you test and troubleshoot your PLC programs. Here's a general step-by-step guide on how you can debug in CoDeSys:

    Set Breakpoints: Start by setting breakpoints in your code. Breakpoints are markers that pause the execution of your code at a certain line so you can examine the state of your program at that point. To set a breakpoint, you can simply right-click on a line of code and select "Set Breakpoint."

    Start Debugging Session: Once your breakpoints are set, start the debugging session by selecting "Debug" from the main menu, then "Start." This will start running your code in debug mode.

    Monitor Variables: While your code is running in debug mode, you can monitor the values of various variables in your program. CoDeSys allows you to watch variables and expressions, providing real-time updates as your code executes.

    Step Through Code: You can use the step functions to move through your code one line at a time. This allows you to observe how each line of code affects your program's state. You can step over functions (execute them without stepping into them), step into functions (execute code within the function one line at a time), or step out of functions (finish executing the current function and pause at the next line of the calling function).

    Modify Variables: During a debug session, you may want to change the value of a variable to see how it affects your program. You can do this by right-clicking the variable in the watch window and selecting "Modify."

    Stop and Restart Debugging: If you want to stop debugging, you can do so by selecting "Stop" from the Debug menu. If you want to restart debugging from the beginning, you can select "Restart."

    Inspecting and Navigating Call Stack: The call stack shows you the nested series of function or procedure calls that led to the current point in your code. It can be a helpful tool for understanding how your program got to its current state, especially when debugging complex applications.

Remember, debugging is a critical part of the development process. It helps you understand how your code works, find errors, and ensure that your program behaves as expected. Effective debugging can lead to more reliable, efficient, and maintainable code.
