Output Datapoints (AO, BO)
Start BACnet output datapoints will be initialized with the relinquish default value. After
the first heartbeat, the relinquish default value or the present value created out of
the application will be sent to the LON bus.
The output priority 1 “Manual Life Safety” represents the status of a local manual
override switch at the LON module (XFL and XFC modules). This information is read
from the Lon Module override switch after every start of the controller.
In principle, the value with the highest BACnet array priority (2 – 8) will be saved in
the battery-retentive RAM (see "Manual Override" section below).
Alarm behavior At the beginning, all output points are not in alarm by default except those of which
output values have caused an alarm.
After the start alarm time has expired, an alarm will be saved in the alarm buffer,
shown in the alarm list and reported to the EBI as long as the alarm exists.
Restart, Reset, Power Failure,
Application- and Firmware Download
The following values/statuses will always be saved in the battery-retentive RAM and
restored after restart, reset, or power failure of the Excel Web controller.
•
Runtime counter
•
Last reset time
•
Elapsed active time
•
Highest output priority of the priorities 2 to 8
NOTE: The datapoint value and the status of the ´Out of Service` flag will not
be transmitted to the LON bus and will not be saved in battery
retentive RAM.
Manual Override The value with the highest BACnet array priority (2 – 8) will be saved in the battery-
retentive RAM and will then be restored after restart, reset, or power failure of the
Excel Web controller.
Reference Inputs
Start Starts with the ´Start Value` defined in CARE. Later the referencing input value will
be taken. For more information on the COV value, please refer also to the "Change
of Value Increment" and the "View / Edit Values" sections).
NOTE:
Reference inputs are not visible in the Excel Web HTML Interface.
Reference inputs will try to subscribe COV. If the source device supports COV, COV
will be subscribed with a life-time of 1800 seconds, and will be re-subscribed every
900 seconds. If the source device does not subscribe COV, the source object (data-
point) will be polled.
Summary
The following table gives an overview of the I/O initialization of the various
datapoints regarding alarming, manual override and behavior at start, restart and
power failure.
