Number of Times of Alarm Delay

In BFM#234, set the number of alarm delays.
This setting is applied to all alarms 1 to 4.
The alarm delay function keeps the non-alarm status until the number of input samples exceeds the number
of alarm delays, after the deviation between the measured value (PV) and the set value (SV) reaches the
alarm set value.
If the deviation remains in the alarm range until the number of input samples exceeds the number of alarm
delays, an alarm is issued.
