volttron BACnet discovery not all points coming through

I am trying to scrape a BACnet device where I noticed not all of the points are being captured on scripts/bacnet/grab_bacnet_config.py

In the screenshot below of the BACnet scanner tool these are the BO's that dont come through:

enter image description here

Any ideas to try?

If I do a vctl config edit platform.driver registry_configs/1100.csv everything seems to be captured but BACnet Binary Outputs (BO's):

EDIT JUNE 2022 Still an issue with the HVAC rooftop unit I am dealing, I put in a github issue here: https://github.com/VOLTTRON/volttron/issues/2976

Solution

  • @HenryHub I ran scripts/bacnet/grab_bacnet_config.py on my BACnet device and was able to get a point that is a binaryOutput. Below is a snippet of the registry csv file that was generated from the script. Note that the first line contains the headers. I add this as a reference. In your case, what would be an example of a binaryOutput register? In other words, if the script were able to capture your binaryOutputs, what should it look like?

    Without knowing the details of the device that you're targeting and since you have direct access to your device, I'd recommend manually writing one binaryOutput and add it to your registry csv file; then see if Volttron can scrape that binaryOutput point. This would do things: 1) If the point can be read, then this suggests that the grab_bacnet_config.py is not working as expected and 2) If the point can't be read, then it might suggest that your device is not allowing access to binaryOutput for some unknown reason. Or it could be related to @DennisVM-D2i's comment above. BTW, I have heard another Volttron user experiencing this same problem; so you are not the only one.

    Example of binary output in the registry file:

    Reference Point Name,Volttron Point Name,Units,Unit Details,BACnet Object Type,Property,Writable,Index,Write Priority,Notes
