Connections to BACnet objects. Only BACnet Objects and no PowerTags are required for BACnet operation.

Licensing - Calculating the Number of BACnet Objects

The licensing of the WinCC OA BACnet driver uses i.a. the counting of used BACnet objects. In order to switch from an older version of WinCC OA to a current version, without counting the BACnet objects, calculate how many objects you need to license by proceeding as follows:

  1. Upgrade your project to the current version, see also Update or patch project.
  2. Start the BACNet driver with the flag -report all.
  3. Within the LogViewer the number of used objects is displayed.
    Anmerkung: When using multiple drivers the number of objects must be summed up.
Anmerkung: For this procedure no device must be connected to the corresponding drivers.
