Hello to all,

there is a problem when I export my function block.
Structered text will be not translated right to cpp:
Please see attachment.

Is there anything wrong with my code? or is there a bug? or.....?

Thank you.

Best regards,
Wolfgang

Hi,

I assume you are pointing to the missing code for the second ELSEIF. Thanks for pointing this out there was an issue in the code generator. In 4DIAC-IDE cset 0d7d4a[1] this is fixed now and will go into 4DIAC-IDE 1.8.

Cheers,
Alois

Thank you for fixing the problem.
Is it possible to fix it on my own with your changes in 1.8 M1? If, yes...what do I have to do?

Best,
Wolfgang

I think the fastest and easiest way is that you try to build your own 4DIAC-IDE. This has the advantage that you can immediately get the fixes you need. Please have a look on the web-page's documentation section under developing chapter -> building 4DIAC IDE from source.

I've also noticed an error, when exporting this one

IF STATE THEN
	IF X < (Y + DIFF_EIN) THEN
		ANF:= TRUE;
		WW := Y;
	ELSIF X > (Y + DIFF_AUS) THEN
		ANF_WW := FALSE;
		WW := 5;
	END_IF;
ELSE
	IF X < (T + DIFF_EIN) THEN
	 	ANF:= TRUE;
	 	TWW := T;
	ELSIF X > (T + DIFF_AUS) THEN
		ANF_WW := FALSE;
		WW := 5;
	END_IF;
END_IF;

An error occured in 4DIAC:
Errors
- Anforderung_WW: Else without preceding IF, ELSIF, or CASE statement
