Time Synchronization BACnet clients such as EBI or 3
rd
-party BACnet front-ends, can time sync the Excel
web controller via the standard time sync or UTC time sync BACnet service. When
having multiple Excel web controllers on a network without any BACnet client being
the time master, the time must be set for any controller separately and correctly
before downloading the application.
EBI Compatibility The Excel Web controller communicates with BACnet front-ends only.
Supported BACnet front-ends are:
• EBI / SymmetrE Software
For more information, please refer to the following software release bulletins:
− EBI R300.1 with Excel Web / BACnet Software Update
− SymmetrE R300.2 with Excel Web Software Update
− EBI / SymmetrE R310.1 or later
• XFI Software
The XFI has not been tested yet with Excel Web, but supports BACnet
functionality.
Operation and Application Software
Programming The Excel Web® is freely programmable using the CARE Engineering Tool and is
thus ideal for all Building Control and Building Management tasks.
This allows making use of standard, pre-tested and pre-documented application and
control strategies.
Application Control Four selectable control loop speed classes (multitasking) with defined cycle times
and switching tables allow tailored and highly effective applications control.
User Administration Your control system is protected by defined user access rights. This ensures that
only authorized persons have access to the system data. There are six pre-defined
user levels. The predefined user levels are arranged hierarchically and the
sequence with descending priority is as follows:
• System Admin (128)
• Project Admin (115)
• Building Engineer (96)
• Operator (64)
• Tenant (32)
• Guest (0)
Excel Web® allows the definition of up to 128 user levels by default. The above
mentioned user levels are available. Each user level can have different read and
write rights assigned, e.g. Display Communication Settings, Create and Delete
Calendars, Change clock settings, etc. Several users with individual passwords can
be defined for each user level.
NOTE: There is no limit to the number of users per user level.
Datapoints Datapoints are the basis of the Excel Web – BACnet system. Datapoints contain
system-specific information such as values, status, limit values, and default settings.
The user has easy access to datapoints and the information they contain.
The user can recall and modify information in the datapoints.
Alarm Handling Alarm handling is defined and realized in the application.
BACnet alarming
On datapoint level, alarming is done by the BACnet intrinsic reporting service.
The following point changes may generate alarm messages:
• Exceeding limit values (analog points and pulse converter point)
• Changes of state (binary and multi-state input and value datapoints)
• Faults (due to, e.g. LON communication errors or e.g. sensors breaks)
