Batch or Bulk change discovered bacnet point device Names

---

I have over 400 points from about 45 different bacnet controllers that were discovered under one local bacnet ip device called "bacnet_network" using Mango 3.3.0. The issue is that I now have all of these points referring to their device name as "bacnet_network" instead of their actual bacnet device name (ie. VAV1). So when look at a list of points, the only thing that i can see is a column called "Device" that refers to the correct numerical bacnet device id for the particular device for a given set of bacnet points. I need to display the "friendly name" of the bacnet device, and not the device id.
Example: I now have 45 points listed as "bacnet_network - zonetemp", where as I need them to display "VAV1 - zonetemp, VAV2 - zonetemp, etc.).

It appears that I could open up each point individually, and change the device name to something other than the local bacnet device name of "bacnet_network", but that could be rather tedious, and prone to error. Any help on this would be appreciated. The funny thing is, when these points were initially discovered, Mango correctly indicated the correct "friendly" name of each parent bacnet device before I added their points to the system.

Hmm. Yes this can be automated, but there'd have to be some input that made it known to the program. For instance, if you had a table of named to device ids, like,

1234,BACnet_Device_001
1235,BACnet_Device_002

you could have a script fix up the JSON for you, like this python script:

import json

mapping = {}
mappingDef = open("/path/to/csvInPartOne.csv")
for line in mappingDef :
  info = line.split(",")
  if len(info) < 2 :
    continue
  mapping[int(info[0])] = info[1]
mappingDef.close()

#Export the points from the data points tab of the edit data source page, 
# or the whole source from the upper table on data sources page
configFile = open("/path/to/exportedPoints.json")
config = json.load(configFile)
configFile.close()
print(mapping)
for dp in config["dataPoints"] :
  if dp["pointLocator"]["remoteDeviceInstanceNumber"] in mapping :
    dp["deviceName"] = mapping[dp["pointLocator"]["remoteDeviceInstanceNumber"]]

outputFile = open("/path/to/output.json", "w+")
outputFile.write( json.dumps( config, indent=4, sort_keys=False, separators=(",",": ")) )
outputFile.close()

Thanks Phil. I'm not all that familiar using python scripts in Mango. In playing around a little, I've noticed that I can export these points to a CSV file. It seems to arrange the point data quite nicely. From there, it looks like I can easily update the Device Names a lot faster using excel. After making my Device name changes in the CSV, can I import this like I would a JSON file, and have it update the existing data point device names automatically? Or, do i need to stick to trying to modify this import using JSON.

Thanks again for the help!

You should always do what makes the most sense to you! I can definitely complicate things sometimes.

Yes you can import the CSV. You will need to import it on the old /emport.shtm page. There is a drop down in the import section to choose between JSON and CSV

Thanks Phil. I should be all set.
