3. 8-bit conversion mode (while M8161 is ON)
(M8161 is used also for the RS, ASCI, CCD and CRC instructions.)
Each ASCII code stored in low-order 8 bits of each device
and later is converted into a hexadecimal
code, and transferred to device
and later in units of 4 digits. The number of characters to be converted
is specified by "n".
M8161 is also used for the RS, ASCI, CCD and CRC instructions. When using the 8-bit mode, set M8161 to
normally ON. 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 has the BCD format, it is necessary to convert BCD data into binary data after
executing this instruction.
