Processing details
• These instructions convert the digit in hexadecimal notation of the 16-bit binary data in the device specified by (s) to the
ASCII code, and store the converted data in the device number specified by (d) and later.
• The format of the hexadecimal ASCII data to be stored in (d) depends on the status of SM705 (Number of conversion digits
selection).

 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.
■Operation overview
The following figure shows the operation when SM705 (Number of conversion digits selection) is off and on.
Ex.
When the BINHA(P) instruction is executed with the 16-bit binary data "0ABCH" stored in (s)
b15 ∙∙∙ b0
(s) 0ABC
• When SM705 is off, the number of digits is fixed. Four digits of "0ABC" are converted into ASCII data and stored.
• When SM705 is on, data is left-justified. "0ABC" with the leading "0" omitted ("ABC") are converted into ASCII data and
stored, and 00H is stored in the end.
