2. 16-bit conversion mode (while M8161 is OFF)
(M8161 is also used for the RS, ASCI, HEX and CRC instructions.)
With regard to "n" data starting from , the addition data and horizontal parity data of high-order 8 bits and low-
order 8 bits are stored to and +1 respectively.
M8161 is used also for the RS, ASCI, HEX 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.
Example of 16-bit conversion
In the following program, conversion is executed as follows:
Example of data contents
Low-order 8 bits of D100 K100 = 01100100
High-order 8 bits of D100 K111 = 0110111 (1)
Low-order 8 bits of D101 K100 = 01100100
High-order 8 bits of D101 K 98 = 01100010
Low-order 8 bits of D102 K123 = 0111101 (1)
High-order 8 bits of D102 K 66 = 01000010
Low-order 8 bits of D103 K100 = 01100100
High-order 8 bits of D103 K 95 = 0101111 (1)
Low-order 8 bits of D104 K210 = 11010010
High-order 8 bits of D104 K 88 = 01011000
Total K1091
Horizontal parity 1000010 (1)
When the number of "1" is odd, the horizontal parity is "1".
When the number of "1" is even, the horizontal parity is "0".
