Control
2. 16-bit conversion mode (while M8161 is OFF) (M8161 is also used for the RS, HEX, CCD and CRC 
instructions.)
Each digit of hexadecimal data stored in 
 and later is converted into ASCII code, and transferred to the high-
order 8 bits and low-order 8 bits of each device 
 and later. The number of digits (characters) to be converted is
specified by "n".
Each ASCII code is stored in either the high-order 8 bits or low-order 8 bits of each device 
 and later.
M8161 is used also for RS, HEX, CCD and CRC instructions. When using the 16-bit mode, set M8161 to normally
OFF. M8161 is cleared when the PLC mode is changed from RUN to STOP.
Operation
In the following program, conversion is executed as follows:
Devices after 
D100 = 0ABCH
D101 = 1234H
D102 = 5678H
Number of specified digits (characters) and conversion result
Bit configuration in the case of "n = K4"
• When outputting data in the BCD format for a printer, for example, it is necessary to convert binary data into BCD 
data before executing this instruction.
