    plz tell me how can I fix this error ??


  • Hi support-jo,

    when I try to save the point ... Property Identifier field can't take the Present Value why ?

    I'm not sure what you mean. If you wanted to use a different property you would have to press the green refresh arrow, as the old UI didn't automatically look up what property types were possible for a given object type.

    plz tell me how can I fix this error ??

    It may be easier with the stacktrace right below what you have shown in the image, but, the first thing to try is deleting your Mango/work/jsp directory. This has the compiled JSPs, which this error is certainly related to. Alternatively you could use the new UI, as BACnet is supported on the new data sources page in 3.6 already.

    I deleted it but the error still exists ...

  • @support-jo
    have you checked the object instance number for the BO? It looks odd. Unless you have thousands of ac units, the number shouldn't be that high (7681).


  • @cwangv It's ok. The objects in a Daikin BACnet Gateway have a strange design.

    @support-jo check my settings, they work:

    If you have a large installation with many Master/Slaves units turn on the cyclic sending (60 sec) and test again. Sometimes the gateway misses a command.

    That is the the expected behavior in the old UI. If you were on the latest Mango you could create this BACnet data source in the new UI, which does not have the refresh arrows on data type and property identifier.

    Speaking of version numbers, what Mango version are you on? It looks like there was a bug fixed with the relinquish tag, which is what the screenshot of the error seems to be about: https://github.com/infiniteautomation/ma-core-public/commit/a6c2a0f8714368c61a0e167bc1cc73328fa48e30

    The stack trace would be in the Mango/logs/ma.log file, accessible through the logging console page or the logging console within Administration --> System Status
