Processing details
• These instructions convert the decimal ASCII data in the device specified by (s) and later to 16-bit binary data, and store
the converted data in the device specified by (d).
• The setting method of the decimal ASCII data to be set in (s) depends on the status of SM705 (Number of conversion digits
selection).
*1
Status of SM705 Setting method of (s)
OFF Set (s) with a fixed number of digits (a sign + 5 digits in
the numeric part).
ON Set (s) with a desired number of digits (maximum: a
sign + 5 digits in the numeric part).
*1 For the firmware version of the CPU module supporting SM705, refer to the following.
 MELSEC iQ-R CPU Module User's Manual (Application)
A CPU module which does not support SM705 operates in the same way as SM705 is off even if it is turned on.
■Setting method of (s) for when SM705 (Number of conversion digits selection) is off
Set decimal ASCII data with the fixed number of digits in (s) to (s)+2.

• The ASCII data in the device specified by (s) to (s)+2 is within the range from -32768 to 32767 for the DABIN(P) instruction,
and it is within the range from 0 to 65535 for the DABIN(P)_U instruction.
• The data of (s)+3 or later is ignored.
• As sign data, set 20H (space) when the ASCII data is positive, and set 2DH (-) when the data is negative. (If a value other
than 20H and 2DH is set, the data will be processed as positive data.)
• A value from 30H to 39H can be set in each place of ASCII code.
• If a value 20H or 00H is set in each place of ASCII code, the value will be processed as 30H.

"-25108" is set in (s) when the DABIN(P) instruction is used
