S
When the X0 = “ON”, this 16-bit instruction converts the content of an ASCII code string at D0~D2, then stores the
result of a BIN number to the D10.

The lowest byte in the string is the sign code for the conversion. If the sign is 2DH, the number is negative;
otherwise, 20H means positive.
The remaining bytes are to store the data of a value. If the ASCII codes in this segment of value have the 20H, 00H
or 30H, that will be treated as 30H.
For a 16-bit instruction, the available range is –32,768~+32,767.
For a 32-bit instruction, the structure of the source string starting from the is shown below.

For a 32-bit instruction, the available range is –2,147,483,648~+2,147,483,647. Therefore, with a sign code, that
will occupy 11 bytes.
If the source string contains a code which is improper or the result is exceeded to the available range, the PLC
will regard that as an operational error.

For a 16-bit instruction, S occupies 3 components For a 32-bit instruction, S occupies 6 components
