Hi'

Can anyone tell me what is wrong here, I can't compile this code.

Code:

FUNCTION_BLOCK FB10
VAR_INPUT
    Step : BOOL;
END_VAR
VAR
    // Static Variables
RET_VAL_1 : INT;
RET_VAL_2 : INT;
END_VAR
    // Statement Section
    IF step = 1 THEN
    FILL(BVAL := P#DB11.DBX0.0 BYTE 32 // IN: ANY
         ,BLK := P#DB12.DBX0.0 BYTE 32 // OUT: ANY
         RET_VAL_1); // INT
    FILL(BVAL := P#DB12.DBX0.0 BYTE 32  // IN: ANY
          ,BLK := P#DB11.DBX0.0 BYTE 30  // OUT: ANY
          RET_VAL_2); // INT         
     END_IF;
         ;
END_FUNCTION_BLOCK

Thanks in advance.

Constant is something that cant change. Like this:

Code:

P#DB11.DBX0.0 BYTE 32

Variable is something that can change, like :

Code:

MyAny

You need to declare your any's as variables and build them, you can use 'AT' for convenience.
