2. 16-bit conversion mode (while M8161 is OFF)
(M8161 is used also for the RS, ASCI, CCD, and CRC instructions.)
Each ASCII code stored in high-order 8 bits and low-order 8 bits of devices and later is converted into a
hexadecimal code, and transferred to devices and later in units of 4 digits. The number of characters to be
converted is specified by "n".
M8161 is used also for the RS, ASCI, 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:
Conversion source data
Number of specified characters and conversion result
" • " indicates "0".
• When the input data is in BCD format, it is necessary to convert BCD data into binary data after executing this
instruction.
• If ASCII code is not stored in in the HEX instruction, an operation error occurs and conversion into
hexadecimal code is disabled. Especially, note that ASCII code should be stored in high-order 8 bits of also
when M8161 is OFF.
