14 Special Functions (BACnet)
14.1 EDE Export of BACnet Objects
The current BACnet server object configuration of BACnet L-VIS models (LVIS-ME200)
is accessible as a set of CSV files following the EDE format convention. They can be
downloaded via FTP from the directory
/data/ede
on the L-VIS device. The files are:
lvis.csv:
This is the main EDE sheet with the list of BACnet objects.
lvis-states.csv:
This is the state text sheet. For each state text reference
in the main sheet, a line contains the state texts for this multi-state object.
lvis-types.csv:
This is the object types text sheet. The file contains a line
for each object type number. Note, that lines for standard object types can be
omitted.
lvis-units.csv:
This is the unit text sheet. The file contains a line for each
engineering unit enumerator value. Note that lines for standard units can be
omitted.
NOTE:
First download the project to the device, wait for the device to restart, and then access the
EDE files. The device will create files matching the loaded configuration when it starts.
14.2 BACnet Network Settings
For BACnet models, selecting the command
Network Settings…
from the
File
menu of
the main window opens a small dialog to configure BACnet specific settings. The
following settings are available:
Character Set:
Allows changing the character set used for string values on the
BACnet network. This setting affects encoding of all string properties of server
objects on the device. It does not limit the ability of the device to receive and
process string values from other devices in other encodings. See also the note
below for more background information.
Enable unsolicited COV:
Send out value changes of local server objects as a
broadcast to all other devices.
Use global instead of subnet wide broadcast:
Broadcast messages are not
directed to the local subnet but instead are sent to the global broadcast address.
This is not conforming to the standard, but some third party devices need this to
work around problems in their software. If needed, it can be turned on here.
