Remote LON Commissioning
Time Programs
Alarming is further supported by notification class objects, which contain information
required for the distribution and segregation by time and addresses of alarm/event
notifications within a BACnet system.
Notification class objects allow up to 256 alarm priorities. By default, CARE provides
3 notification class objects matching the EBI alarm priorities:
• Urgent
• High
• Low
IMPORTANT
The internal ring alarm buffer takes max. 100 alarms.
Excel Web does also support the BACnet algorithmic alarming service.
The algorithmic alarming uses the standard BACnet "Event Enrollment Object" and
is used to provide the following functionality:
•
Warning limits for analog datapoints (Min. and Max. warning limits, in
addition to the Min and Max Alarm limits)
•
Alarming for datapoint change between "auto" and "manual"
•
Alarming for missing or late acknowledgement of alarms
•
Maintenance alarming, based on elapsed runtime of datapoints or number
of state-changes of datapoints.
•
Alarming for unsuccessfull transmission of Email alarms
•
Alarming for stopped or started plants within Excel Web
LON alarming
As LON does not know "devices" but only NVs, I/O module alarming must be
realized by mapping a particular NV to the appropriate "alarm" datapoint in CARE.
Then for the alarm datapoint, the alarm settings are to be defined as usual.
Excel Web Controllers on a LON bus can be commissioned remotely via LAN / WAN
using CARE or Excelon (can be used as LonWorks protocol analyzer via LAN).
Time programs comprise schedules and calendars.
Schedules
Schedules are daily and weekly time programs.
Whenever you want, you can use schedules to enter the setpoint or status for any
datapoint.
Schedules are assigned to plants. Each plant of a controller can have multiple
schedules assigned and each schedule can command datapoints of that plant.
Each schedule specifies a list of datapoint properties to command (switchpoints) on
a weekly basis. The week program defines the normal daily activity of the system by
specifying which switchpoints are to be commanded each day of the week. The
week program applies to a definable time period. There is only one-week program
per schedule.
Schedules offer 16 write priorities that define the priority for writing to the present
value of output and value datapoints. Note that only priorities 9 to 16 are allowed in
the controller.
The write priority applies only to the present value property of virtual points and
output points. The write priority is ignored for all other types of properties.
For every schedule (week program), specific programs called exceptions can be
created. Exceptions have higher priority than the week program and will overwrite
the week program for a definable time period. Exceptions can be one of the
following four time periods:
• Specific Date
e.g. Christmas Eve or 5.5., the whole of May, or the whole year of 2004
• Date Range
e.g. Summer holidays from 29.7-7.9.2004
• Recurring Event
e.g. every last Friday of every month
