DATA (L)
Alarm 1
● Half numerical data instructions
Data that corresponds to the executed
instruction code is output.
00h is output when there is an abnormality. *
3)
● Full numerical data instructions
Alarm code shown as a 3 digit decimal number
when numerical data reading is enabled and an
alarm is generated. In the half numerical data
instruction mode, up to two alarms can be
output. In the full numerical data instruction
mode, up to four alarms can be output.
The latest alarm code generated will be output to
alarm 1. Alarm is updated by another alarm. The
code of the previous alarms generated will be
shifted to alarm1

When the number of alarms generated exceeds
the maximum alarm output for each mode, the
oldest alarm code is deleted from the record.

*3) When the error occurred in the data edit function by the specified address which is out of the range etc.,
the value of 80h that is the OR (logical add) is output to Sub Function which set in RWw1 is returned to
Sub Function RWr3 (RWr9 at Full numerical data instructions), and the received error code is returned
to DATA (H) [RWr6] (RWrC at Full numerical data instructions). And RWr4:Address and RWr7: DATA
(L) ( RWrA and RWrD at Full numerical data instructions) will be 00h. Error code is shown below.
