(Note 1) The I/O numbers in the tables above show offset addresses. Actual I/O numbers allocated to the analog
input unit are determined by the first word number. (Example) If the first word number is 10, the A/D conversion
data on CH0 and the error flag will be WX10 and X11F, respectively.
(Note 2): The conditions of the buffer function (i.e., the buffer function execution flag, buffering flag, buffering
completion flag, and data enable flag before triggering) are allocated to the input contacts for CH0.

ON with disconnection detected and OFF
with disconnection restored
(valid for 1 to 5 V and 4 to 20 mA ranges
only)
Turns ON when the value exceeds the set
upper limit.
Turns ON when the value drops below the
set lower limit.
ON when the function for comparing upper
and lower limits is executed.
Do not use.
ON when the max./min. hold function is
executed.
Do not use.
ON when the buffer function is executed.
ON when buffering starts after the trigger is
accepted.
OFF when the number of buffer data items is
reached.
ON when the shared memory has become
accessible after completion of buffering
OFF on completion of buffer data reading.
ON when the number of buffer data items
before triggering has reached the set value.
OFF on completion of buffer data reading.
Do not use.
Turns on if an error occurs.
