LOYTEC L-Gate - EDE Export of Bacnet Objects

L-Gate User Manual 148 LOYTEC
Version 3.2 LOYTEC electronics GmbH
The CSV file must be named “bacclnt.csv” and stored in the directory “/var/lib/bacnet” on
the L-Gate. The file is read when the device boots. If any errors occur they are reported in
“/tmp/bacclnt.err”.
The column format is shown in Table 11. Lines beginning with a hash (‘#’) sign are
comment lines. The example values in Table 11 setup a client mapping named “Lamp
Room 302”, which writes (mapping type 2) the present value of the local object AI,4 to the
remote object AO,1 on the device with the instance number 17801.

7.3.3 EDE Export of BACnet Objects
The BACnet server object configuration of the L-Gate 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 device. The files are
• lgate.csv: This is the main EDE sheet with the list of BACnet objects.
• lgate-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.
• lgate-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.
• lgate-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.
