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
high-order 8 bits and low-order 8 bits of each device
converted is specified by "n".
Each ASCII code is stored in either high-order 8 bits or low-order 8 bits of each device
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.

• 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.
