2. Turning ON the bit out of word devices according to the contents of bit devices
The value expressed by X000 to X002 is decoded to D0 (X000 and X001 are ON, and X002 is OFF in this
example).
• When the values expressed by X000 to X002 are "3 (=1+2+0)", b3 (which is the 4th from b0) becomes "1"
(turns ON).
• When all of X000 to X002 are "0" (OFF), b0 becomes "1" (turns ON).
