Sorry I made a mistake, it's actually the device Object itself that's giving me issues.


refs.add(device.getObjectIdentifier(), PropertyIdentifier.all);

that line puts the object itself in the list to get the PropertyValues, but for some reason when I call this line with the device in the references it error's out:


pvs = localDevice.readProperties(device, ref );

then I get this error:


com.serotonin.bacnet4j.exception.AbortAPDUException: Abort(server=true, original InvokeId=11, abortReason=Other)

Ok, so I've been doing so playing and here is what I learned. I broke my PropertyRefernces down into a small list of only 1 element each and them call for the PropertyValues and now it works until it gets to the file object. Both the Siemens and the KMC panel have file objects in them but apparently you can't read the PropertyValues on a file object or it crashes out. Now I just need to figure out some way of making it keeping going after an error.

In terms of segmentation, the older MS/TP panel I have does not support it apparently but the 2 newer Ethernet panels do have it and it works.

Thanks for the help, I'm getting a much better understanding of the Bacnet4J but I still don't understand why the file objects error out, but I have seen this on other BACnet workstations where the files cannot be retrieved or backed up.

Here is my code I'm currently using:

I downloaded version 1.14 jar file from the CVS on sourceforge but I still get the same result. I tried with another vendor panel and a get a similar issue. I can't seem to call for PropertyValues without an ADPU error.

I'm switched from a Siemens Bacnet panel to a KMC bacnet pane and now I get:


com.serotonin.bacnet4j.exception.RejectAPDUException: Reject(originalInvokeId=3, rejectReason=0)

Here is my code I'm playing with trying to learn the functions and how to use them.

I have several BACnet devices on my test network and I'm trying to learn Bacnet4J as I have some ideas of future uses for my own BACnet items.

The first thing I'm trying to do is find the devices, read the objects in the devices and check the present values of the devices. I have used the whois to get the devices and I can get the property refernces. But when I call for the property values I get an error:

The line of code I'm using is:


PropertyValues pvs = localDevice.readProperties(device, refs);

and the error I get is:


com.serotonin.bacnet4j.exception.AbortAPDUException: Abort(server=true, original InvokeId=3, abortReason=Other)

I don't know what it means or how to handle it because it's not really an exception making back to my catch.

Also on another note I had to turn off one of my older BACnet panel because it gives me APDU errors also. Is it possible the older panels are compatible? This is the error I get from that panel when I turn it on:


Exception in thread "main" com.serotonin.bacnet4j.exception.AbortAPDUException:
Abort(server=true, originalInvokeId=15, abortReason=Segmentation not supported)
        at com.serotonin.bacnet4j.LocalDevice.send(LocalDevice.java:428)

        at com.serotonin.bacnet4j.LocalDevice.sendReadPropertyAllowNull(LocalDev
ice.java:716)
        at DiscoveryTest.main(DiscoveryTest.java:62)

I am familiar with BACnet and java but it's been a long time since I've programed from scratch, so if there is any place for me to look up and understand why I have communication errors, let me know because it just seems like I'm missing something easy. Thanks!
