Calling Operator
man_fun1
12.7.2Content Operator
A pointer can be dereferenced by adding the content operator "^" after the pointer identifier.
Example in ST:
pt:POINTER TO INT; var_int1:INT; var_int2:INT;
pt := ADR(var_int1); var_int2:=pt^;
12.8 Calling Operator
12.8.1CAL
Calling a function block or a program
Use CAL in IL to call up a function block instance. The variables that will serve as the input variables are placed in parentheses right after the name of the function block instance.
Example: Calling up the instance Inst from a function block where input variables Par1 and Par2 are 0 and TRUE respectively.
CAL INST(PAR1 := 0, PAR2 := TRUE)
12.9 Type Conversion Functions
Its is forbidden to implicitly convert from a "larger" type to a "smaller" type (for example from INT to BYTE or from DINT to WORD). Special type conversions are required if one wants to do this. One can basically convert from any elementary type to any other elementary type.
Syntax:
<elem.Typ1>_TO_<elem.Typ2>
Please regard that at ...TO_STRING conversions the string is generated leftjustified. If it is defined to short, it will be cut from the right side.
12.9.1BOOL_TO Conversions
Conversion from type BOOL to any other type:
WAGO-I/O-SYSTEM 759 WAGO-I/O-PRO 32
The IEC Operators • 305
Type Conversion Functions
For number types the result is 1, when the operand is TRUE, and 0, when the operand is FALSE.
For the STRING type the result is ‚TRUE' or ‚FALSE'.
Examples in AWL:
LD |
TRUE |
|
|
BOOL_TO_INT |
|
|
|
ST |
i |
(*Result is 1 *) |
|
LD |
TRUE |

(*Result is 'TRUE' *) |
|
LD |

|
|
BOOL_TO_TIME |

|

|
|
BOOL_TO_DT |
|

Examples in St: |
|

(* Result is 1 *) |
||
str:=BOOL_TO_STRING(TRUE); |
(* Result is "TRUE" *) |
t:=BOOL_TO_TIME(TRUE); |
(* Result is T#1ms *) |
tof:=BOOL_TO_TOD(TRUE); |
(* Result is |
TOD#00:00:00.001 *) |
|
dat:=BOOL_TO_DATE(FALSE); |
(* Result is D#1970 *) |

Examples in FUP:
(*Result is 1 *)
(*Result is 'TRUE' *)
(*Result is T#1ms *)
(*Result is TOD#00:00:00.001 *)
(*Result is D#1970-01-01 *)
(*Result is DT#1970-01-01- 00:00:01 *)
12.9.2TO_BOOL Conversions
Conversion from another variable type to BOOL:
The result is TRUE when the operand is not equal to 0. The result is FALSE when the operand is equal to 0.
The result is true for STRING type variables when the operand is "TRUE", otherwise the result is FALSE.
Examples in AWL:
LD |
213 |
|

(*Result is TRUE *) |

Examples in St: |
|
b := BYTE_TO_BOOL(2#11010101); |
(* Result is TRUE *) |
b := INT_TO_BOOL(0); |
(* Result is FALSE *) |
b := TIME_TO_BOOL(T#5ms); |
(* Result is TRUE *) |
b := STRING_TO_BOOL('TRUE'); |
(* Result is TRUE *) |
12.9.3Conversion between Integral Number Types
Conversion from an integral number type to another number type:
When you perform a type conversion from a larger to a smaller type, you risk losing some information. If the number you are converting exceeds the range limit, the first bytes for the number will be ignored.
Example in ST:
si := INT_TO_SINT(4223); (* Result is 127 *)
If you save the integer 4223 (16#107f represented hexadecimally) as a SINT variable, it will appear as 127 (16#7f represented hexadecimally).
