    Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

    Check any of your JSONVARs. The Names variable contains an array of the variable name divided by level. For example, if the variable path is Application.Test_SingleVar_PRG.colour, then the array will contain [3] 'Application' [2] 'Test_SingleVar_PRG' [1] 'colour' The ApplicationLevel property should be the array index which contains 'Application', in this case 3. This is all figured out in the JSONVAR.FB_Init method. The other place to check is JSONVAR.VarName, which is the full instance path of...

    Correct. In an actual use case I think the compose and parse would happen on different machines.

    If you can post an example I can test it here.

    The EXIT is in the correct place in the original, this is not a bug. The loop returns FALSE and exits on the first occurrence of a mismatch. If there are any mismatches, there is no point in evaluating the rest of the array. All levels must match for this method to return TRUE.

    I'm getting this error on one of my projects. Searching for it I came across this https://www.codesys.com/fileadmin/data/Images/System/Releaseinformation/Patch-Note-CODESYS-Visualization-4300.html which says it was a bug VIS-1394, fixed in Visualization 4.3.0.0. I'm using a previous visu version, what is the cause of this error, and what can be done to work around it?

    It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

    maybe this would be a better approach, then you don't have to pass the constant at all. FUNCTION fun : INT VAR_IN_OUT arr: ARRAY[*] OF INT; END_VAR VAR lower: DINT; upper: DINT; END_VAR lower:= LOWER_BOUND(arr, 1); upper:= UPPER_BOUND(arr, 1); see here as well https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_datatype_array/
