Typecast SINT(expression)

The SINT typecast operator is used to convert an expression to a SINT type. If the typecast operator is used on a "larger" type, truncation will occur.

Example:

INCLUDE rtcu.inc
 
VAR
   a : INT; 
   b : SINT;
END_VAR;
 
PROGRAM test;
 
BEGIN
   // Convert 'a' which is a INT type to a SINT (truncation will occur)
   b := SINT(a);
   ...
END;
 
END_PROGRAM;
