Processing details
• These instructions convert the decimal ASCII data stored in the device areas specified by (s) and later to BCD 8-digit data,
and store the converted data in the device number 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 (8 digits).
ON Set (s) with a desired number of digits (maximum: 8
digits).
*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 8 digits (fixed) in (s) to (s)+3.

• The ASCII data in the device specified by (s) to (s)+3 is within the range from 0 to 99999999.
• The data of (s)+4 or later is ignored.
• 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.
