Example:
The alarms for psTemperature below are set so that the normal temperature range
is from 30°C to 45°C. If the temperature rises above 45°C, a casHI alarm will be
sent to the alarmTable. Anything over 50°C is considered a critical condition and
will generate a casHIHI alarm. If the temperature falls below the normal level of
30 degrees, and casLO will be generated, and if it continues to drop below 0, a
casLOLO will be generated. The temperature must rise above the LOLO limit plus
the deadband value of 3°C before the casLOLO alarm will change to a casLO. The
alarmEnable eld is set to 0F Hex to monitor and alarm for all conditions.
