32-bit bi nar y number
If SM690 is OFF, 16#0000 is stored in the high 8 bits in D+5. If SM690 is ON, 16#20 is stored
in the high 8 bits in D+5. Besides, if the value in S is a positive value, the sign character in D is
16#20. If the value in S is a negative value, the sign character in D is 16#2D. For example, if
the value in S is -12345678, the conversion result is as follows.
S
-1234
32-bit binar y number
5. Take the 32-bit binary number -12345678 in S for example. The digit in the hundred millions
place of the number and the digit in the billions place of the number are 0. When the instruction
is executed, 16#20 is stored in the low 8 bits in D+1 and the high 8 bits in D.

Becoming 16#20
Example 1:
Suppose the value in L0 is 5126 and SM690 is OFF. When the PLC runs, the values in D0, D1, D2,
and D3 are 16#2020, 16#3135, 16#3135, and 16#0000 respectively.
