alarm hysteresis. The directions are reversed for
low limit detection. The hysteresis is also used for
warnings.
Alarm/Warning Limits
Upper Limit Alarm: Upper alarm limit in engineering units.
Upper Limit Warning: Upper warning limit in engineering units.
Lower Limit Warning: Lower warning limit in engineering units.
Lower Limit Alarm: Lower alarm limit in engineering units.
HI_HI_ALM
Unacknowledged Alarms: Unacknowledged alarms.
Status: Status for the upper alarm.
Time Stamp: The time of day when a change in limit stated was
detected that was unreported.
Cause: Cause of the upper alarm.
Alarm Output Value: Output value at the time of the upper alarm.
HI_ALM
Unacknowledged Warnings: Unacknowledged warnings.
Status: Status for the upper warning.
Time Stamp: The time of day when a change in limit stated was
detected that was unreported.
Cause: Cause of the upper warning.
Warning Output Value: Output value at the time of the upper warning.
LO_LO_ALM
Unacknowledged Alarms: Unacknowledged alarms
Status: Status for the lower alarm.
Time Stamp: The time of day when a change in limit stated was
detected that was unreported.
Cause: Cause of the lower alarm.
Alarm Output Value: Output value at the time of the lower alarm.
Simulation
Simulation Value: For commissioning and maintenance reasons, it is
possible to simulate the Read back by defining the
value and the status. That means that the
Transducer Block and the Function Block will be
disconnected.
Status (Simulation Value): Status for the simulate value.
Simulation: Enable or disable the simulation.
