DWORD_TO_BINSTR

DWORD_TO_BINSTR 1:

This function converts a decimal number into a binary string (base 2).

FUNCTION DWORD_TO_BINSTR: T_MaxString

VAR_INPUT

VAR_INPUT
    in         : DWORD;
    iPrecision : INT;
END_VAR

in: The decimal number requiring conversion.

iPrecision: Minimum number of displayed digits (digits). If the actual number of significant digits is less than the iPrecision parameter, the resulting string is filled with zeros from the left. If the number of significant digits is greater than the iPrecision parameter, the resulting string is not cut off! If the iPrecision parameter and the in parameter are zero, the resulting string is empty.

Example:

PROGRAM MAIN
VAR
    s1   : STRING;
    s2   : STRING;
    s3   : STRING;
    nCnt : BYTE;
END_VAR
s1   := DWORD_TO_BINSTR( 16#81, 16 );
nCnt := 15;
s2   := DWORD_TO_BINSTR( nCnt, 1 );
nCnt := 0;
s3   := DWORD_TO_BINSTR( nCnt, 0 );

The result:

s1 = '0000000010000001'

s2 = '1111'

s3 = ''
