9.8 Calling Operators...

9.8.1 CAL

PLC Designer IEC operator: 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)

9.9 Type Conversions...

9.9.1 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 left-justified. If

it is defined to short, it will be cut from the right side.
