Hello,

now with this code i get the following response:


ObjectIdentifier oid = new ObjectIdentifier(ObjectType.multiStateValue, 0);
            for (int i=1; i<2; i++) {
                PropertyReferences refs = new PropertyReferences();
                refs.add(oid, new PropertyIdentifier(79));
            
                PropertyValues pvs = localDevice.readProperties(d, refs);
                for (ObjectPropertyReference opr : pvs){
                    System.out.println(""+ i +": "+ pvs.getNoErrorCheck(opr));
                }
            }


1: Multi-state Value

The objectidentifier was wrong.

But with this code


  ObjectIdentifier oid = new ObjectIdentifier(ObjectType.multiStateValue, 0);
            for (int i=1; i<2; i++) {
                PropertyReferences refs = new PropertyReferences();
                refs.add(oid, PropertyIdentifier.all);
            
                PropertyValues pvs = localDevice.readProperties(d, refs);
                for (ObjectPropertyReference opr : pvs){
                    System.out.println(opr.getPropertyIdentifier() +" "+ i +": "+ pvs.getNoErrorCheck(opr));
                }
            }

i got this error message:


All 1: errorClass=Property, errorCode=Unknown property

How can i read now the object-properties from the multi-state-value?

Thanks for help

Hello,

now i have deinstall the wago-bacnet driver and start the programm after a new boot. i think it works. No errors.
Now i get this output:

8: errorClass=Object, errorCode=Unknown object

what does it mean exactly?

thank for help:

Hello,

i'am new to bacnet4j. I try since a few day to run the little test-programm but with no suggest.

My hardware is a wago 750-830 bacnet-controller. when i run the programm with the following line i got an error like this.
