Siemens SCL (SFB4)

[cjd1965]

Hi
I am trying out SCL and wish to use a stat SFB4 with a preset from a DB, Say Stuff, T1 where T1 is type TIME

Compiles

FUNCTION_BLOCK FB20
VAR
Timer1 : SFB4;
END_VAR
Timer1(IN := M0.0,PT:=T#10S); 

;  
END_FUNCTION_BLOCK

Wont Compile

FUNCTION_BLOCK FB20
VAR
Timer1 : SFB4;
END_VAR
Timer1(IN := M0.0,PT:="Stuff".T1); 

;  
END_FUNCTION_BLOCK

How do i point the SCL at the DB for the timer preset?

 

[L D[AR2P#0.0]]

Change your variable name from T1 to tTime in the DB

The compiler thinks T1 is a S5 timer......

Thanks, you cracked it. The compiler error code didnt come close. Dare say there will be other quirks as i progress.
