Proprietary BACnet properties to be integrated in WinCC OA

Post by nicolas.chaix » Thu Jan 31, 2019 2:14 pm

Dear community,

I need to read a proprietary BACnet property on a device object (object type 8).
In the _address config entry, the properties are listed in a dropdown list.
If I know the property's ID, is that possible to derogate to this list and define a specific one.

Same question about a proprietary BACnet object type...

Thanks for your reply!

BR,

Nico

Hello Nicolas
The BACnet objecttypes and properties are defined in the following files, which are stored in the "\data\bacnet\"-folder of the WinCC OA version installation path:
“BACNet_objecttype_mapping.cat” and “BACNet_properties_mapping.cat”.

You can copy these files to the "\data\bacnet\"-folder of your project and adapt them. New Objecttypes and their properties can be added in the file “BACNet_objecttype_mapping.cat”. Expanding the BACNet_objecttype_mapping.cat will work if the property data type is known in WinCC OA, that means if it is for example a "string" . If the object type has also a Present_Value you have to explicitly set the transformation I the address-panel.

I hope this answer will help you.

BR,
Mousser
