Operation
When the digital operation value to which the shift amount is added is above the warning output upper limit value or below the
warning output lower limit value and the warning output condition is satisfied, the "warning output upper flag" or "warning
output lower flag" turns ON.
When warning is output, the setting value of the "warning output upper limit value/warning output lower limit value" is regarded
as the digital operation value and D/A-converted.
Even if the digital value changes to a value below the warning output upper limit value and above the warning output lower
limit value after the warning output, the "warning output upper flag" and "warning output lower flag" do not turn OFF. When the
alarm clear request is set to OFF, ON and OFF again, the "warning output upper flag" and "warning output lower flag" turn
OFF. The "warning output upper flag" and "warning output lower flag" turn OFF also when the "warning output enable/disable
setting" is changed to "disable", but the alarm code stored in the "D/A conversion latest alarm code" is not cleared.
For clearing the alarm code stored in the "D/A conversion latest alarm code", set the alarm clear request to OFF, ON and OFF
again.
