Controller Based Trending

• Calendar Reference
A project-wide calendar provides dates, e.g. regional holidays and
public/religious festivals or any other particular date. The time period can be a
specific date, a date range or a recurring event.
Calendars
Calendars contain exception days or periods, e.g. Christmas, holidays. Calendars
are valid for the whole project, and are executed in each controller but apply only to
those schedules, which reference calendars. Changes in multiple particular
controller schedules can be quickly made by simply changing a calendar in one
controller. Thus project-wide scheduling can be influenced.
Trending Trending can be performed via the Excel Web HTML Interface residing on any PC
platform and via BACnet clients. Trend data is stored on an 2 MB integrated Flash
memory which can hold a maximum of 64,000 trend records distributed among 125
trend log objects. In addition, three trend log objects are used for LON statistic
trending. A single trend log object can include max. 2.880 trend records (max. trend
buffer size). One trend record equals 30 bytes. Extended trend memory is possible
by using a 3
can be in ´Ringbuffer` mode or in ´Stop When Full` mode. Trend data are
dynamically created in the controller and can be saved in a .CSV file.
Trend data have unlimited lifetime and survive an application download. Trend
objects must be explicitly deleted via Excel Web HTML Interface or BACnet. This
deletes also the corresponding trend records. The trended object may be a local or
a reference point in the same controller and the trended property may be integer or
floating point, e.g. point value, point state, alarm limit, time stamp.
Trending via BACnet Client
BACnet clients like EBI will use the BACnet ´read range service` to readout trend
values from the Excel Web controller. Trend recovery for BACnet clients, specifically
EBI and SymmetrE optionally provide an automated recovery mechanism which
allows to "backfill" missing trend data on the BACnet client side with trend values
from the Excel Web controller.
A Compact Flash Card (type 1 or type 2) or micro drive allows memory extensions
for the purpose of expanding integrated trend memory and increasing historical data
storage. The integrated on-board trend memory allows saving of max. 64.000 trend
values.
Protocolling In the context of the Excel Web controller, "protocolling" means creating a log of the
values or states of the datapoints, which have been assigned to this particular Excel
Web controller. Using the Excel Web HTML Interface, the user must place the
corresponding datapoints into "trend". If, at some later point in time, i.e. after lengthy
operation, a protocol of the Excel Web controller's history is desired, the
corresponding trend data can be generated, viewed, and downloaded (in CSV
format) via the browser interface. For the storage of larger amounts of trend data
(more than 64,000 trend entries – corresponding to approx. 2 MB), a CF card or
micro drive can be used. The trend data can even be downloaded into a BACnet
client if this client supports this BACnet service.
When connected to the Excel Web controller via Internet Browser, all other Excel
Web controllers of the same project can be operated without the necessity of a new
login.
The Excel Web controller supports the BACnet Backup/Restore functionality by the
backup/restore of the application files.
When performing a backup/restore of the application files, the following must be
noted:
• Online changes may not be considered circa 1 minute before the backup is
started.
• Do not restore the application if the LON interface of the controller has been
changed via CARE.
