In both cases, the following device and object information from the BACnet source or target points must be entered
during the mapping:
• Device Instance (ID)
•
Object type (BACnet point type) = object ID
• Object Instance = object ID
Automatic Reference Point Creation and Mapping via Drag & Drop
Reference points can be automatically created and mapped to physical or value BACnet points by dragging & dropping
the physical or value BACnet points onto the wiresheet. In this case, the corresponding device and object information
comes with the corresponding BACnet point and must not be entered manually.
Master – Slave Configurations
A typical application scenario for the usage of reference points is a master-slave configuration consisting of one master
controller connected to multiple slave controllers and/or 3
control logic, writes values to the slave controllers and/or 3
controllers and/or 3 rd Party BACnet devices.
Example:
• The master controller:
- reads the window contact status [EffWindow] from the slave controller via RefIn
- reads the room temperature [ExtWmRmTemp] from the externa BACnet Wall Module via RefIn
- writes the occupancy status [EffOccMd] to an external BACnet Wall Module via RefOut
• The slave controller:
- reads the fan output status [FanStage] of the staged fan (slow, medium, high) from the master controller via
RefIn (see figure next page).
