Dear All ,

Thank you for your help.

I have a STL code trying to convert to SCL but not able to get the right match.

SCL CODE 

Could you please guide me as what i am doing wrong.

With Regards,

Hello Prayag,

in my opinion do you need one more END_IF.

SCL CODE

Hi,

Your STL code looks like transleted automatically from LAD into STL, so it's quite difficult to read and understand. Try to translate it again into LAD so then will be much easier to type SCL code base on it.

nope its not translated from Ladder it is converted from SCL. I am sure if it. Hence the query. ,

Thanks for the reply though.

FUNCTION_BLOCK FB001

VAR_INPUT
  In : REAL;
  Minimum :REAL;
  Maximum : REAL;
  Load : BOOL;
  Perm : BOOL;
END_VAR

VAR_OUTPUT
  Out: REAL;
  valid:BOOL;
END_VAR

VAR
  loadOld: BOOL;
END_VAR

IF Load AND NOT LoadOld AND Perm THEN
  valid:= (LIMIT (Mn:= Minimum , in:= In ,Mx:=  Maximum) = In);
  IF valid = true THEN
    Out := In;
  END_IF;
END_IF;

END_FUNCTION_BLOCK

is in STL: 

      SET
      SAVE
      =     L      0.1
      A     #loadOld
      NOT
      A     #Load
      A     #Perm
      JCN   A7d0
      L     #In
      L     #Minimum
      >=R
      TAK
      T     LD     2
      TAK
      JC    A7d1
      T     LD     2
      JU    A7d2
A7d1: L     LD     2
      L     #Maximum
      <=R
      JC    A7d2
      T     LD     2
A7d2: L     LD     2
      L     #In
      ==R
      =     #valid
      JCN   A7d0
      T     #Out
      A7d0: CLR
      A     L      0.1
     SAVE
     BE

It does the same as your code.

Looks like you posted not the complete STL code (where is "A7d5"?), I assume this causes the differences after "=     #valid"
