Aliases can be used to give any server item a user-defined name. Aliases can be seen as a short-cut to the original server item. Therefore, an alias is not a copy of the source item – it is just alternative way to access an item. Aliases can be used to give physical datapoints a more descriptive name. Furthermore, aliases can also be arranged in a user-defined hierarchy.
The structure of the alias definition file is as follows:
| Code Block |
|---|
' Aliases Definition File |
...
' |
...
' SourceItemID;Name;Path |
...
;Comment NETx\XIO\KNX\BROADCAST\03/0/002;LightOff;BuildingA\Floor1\ |
...
; NETx\XIO\BACnet\Device1\ANALOG_VALUE_0\ANALOG_VALUE_0 - PRIO 15;HeatingSetpoint;BuildingA\Floor1\RoomA; |
Each line – except comment lines that start with ' – defines a single alias.
