Its possible to declare in FC the static variable

Hello,

I found some stranges in SCL code.

Its possible to declare in FC the static variable:

FUNCTION Material_code_check:VOID

VAR_INPUT

Fl  :BOOL;

END_VAR

VAR_IN_OUT

Control  :"Parameters";   // Struct of UDT2

END_VAR

VAR
Parameter_material :STRING[10];
Source_material :STRING[10];
Target_material :STRING[10];

END_VAR

How it would be work ? I suppose in this case it would be normal TEMP variable ?

The Function can be compiled without Failure. Also by Test this Block its Works! But i need to be ssure what happened now if i declare in FC the static variable? In STL, KOP, FUP the static declaration is not possible in FC only in FB.

Kind Regards

Split from Step 7 SCL help with increasing/decreasing variable .

There's nothing like static variable in FC. In FCs keyword VAR has the same meaning as VAR_TEMP.

Thanks for Info! =)

Kind Regards
