The persistent problem is that, while the code compiles without errors or warnings, the simulator balks at a download with error: "C0367 Internal error 3 prohibiting online change! Clean application and download necessary". Cleaning the application makes no difference. I have been unable to track down the cause of the error and was hoping to find some help from someone who might have a better grasp of OOP principals as applied to CODESYS. There is a possibility of a call to an un-instantiated object, but i haven't found where.
An additional question i have is about the CODESYS "NULL" definition. The code compiles with NULLs, but the editor doesn't appear to recognize it as a defined symbol. I have tried replacing all the NULLs with a numeric '0' - this also compiles without errors, but made no difference to the download.
Any clues to getting this running would be appreciated.
Thanks,
Jeff
Hi All;
I have been translating the (open source) eFFL Fuzzy Logic library https://github.com/zerokol/eFLL

EDIT 1: Changed attached file to .project
EDIT 2: Corrected .project file attached
Fuzzy_eFFL r024_A.project [183.92 KiB]
a null is not equal to a zero, null is nothing mostly 00 hex and a null is a symbol
Hi,
you need to attach the .project file not the opt filesβ¦!

Thanks Edwin.
Find attached .project file in the edited post above
It took a bit of head scratching, but the solution presented itself eventually.
In a few cases, I was creating new objects like this:
IF ((aux := __NEW(fuzzySetArray)) = 0) THEN
// do something
END_IF
If the object creation is taken out of the IF statement, like this:
aux := __NEW(fuzzySetArray);
IF (aux = 0) THEN
// do something
END_IF
...then the download fault disappears and the simulator is ready to run.
Find the corrected (..._A.project) file attached to the first post above.
