    I'm sure this is very obvious, but I'm new to CodeSys trying the Traffic Signal tutorial program and I'm stuck on this error:

    Error 4024:Variable_Configuration(1) Expecting VAR_GLOBAL before 'VAR_INPUT'

    My config is:

    VAR_INPUT

    STATUS:INT;

    VAR_OUTPUT

    GREEN:BOOL;

    YELLOW:BOOL;

    RED:BOOL;

    END_VAR

    No matter where I insert VAR_GLOBAL, it still fails. Any ideas?

    global variables are in a special section on resources.

    easier way is when you type in a vriable name and auto is on the first field is where it should go and give it global.

    i always make first work of these global variables.

    i put all real inputs from %IX and %QX on these global ones so i can find them allways.

    btw system does same when you config it.

    In "Variables Configuration" section, the keyword VAR_CONFIG is expected.

    Putting them in Global Variables solved the problem, thanks for the help!
