Great!

Hmm, I'm not sure. You could try doing a ReadPropertyRequest for the present value, instead of trying to get the whole Object.

Hi cenk,

I'm not sure precisely what you mean, but, you can issue a request to it and see if it responds.

Hi gadi.alaloof,

I think this thread might be similar: https://forum.infiniteautomation.com/topic/3121/unable-to-discover-a-bacnet-device-on-my-network/18

The resolution there was found in using a local bind address of 0.0.0.0 and a broadcast address particular to the network, like 192.168.1.255 for the 192.168.1.0/24 network. BACnet local device settings are on the /system_settings.shtm page

@phildunlap said in BACnet string point:

BACnet module 3.3.1 is released!

Thanks

I found a solution, although it's not ideal.

If you disable communications via LocalDevice.setCommunicationControl after having subscribed, you get the behavior I'm looking for. This seems a bit heavy-handed when all I want to do is turn off acknowledgment for a single service, but it will do for the time being until someone shows me a better way.

Hi Wingnut,

I don't believe it is currently possible. I looked around the code a little, and I think it's SubscribeCOVRequest that is the outgoing form used, and it doesn't have these options. I imagine it's something we're interested in supporting, but have no sense of a timeline to offer offhand. Doesn't seem like it would be too much to add, but I can't say.

Great! Hope that does what you need.

Pretty much any time the script is going through Java code to do something, it'll happen during validation or actual runtime the same. Things like the RuntimeManager, JsonEmport or calling the set() function will only actually change things if running, since they're going through mechanisms particular to the scripts.

Looks like there's nothing there. I'll send you an email.

@leon said in Examples in "src_test/com/serotonin/bacnet4j/test" cannot compile:

/src_test/com/serotonin/bacnet4j/test/"

Thanks for the confirmation. So it seems like the sample files in the project are indeed not yet updated. If anyone has updated versions of these sample files and could share them it would be most appreciated!

@joolz said in How to get current device time?:

For a device object, you can read the Local_Date and Local_Time properties.

Is there some kind of LocalDevice/ RemoteDevice method do this ? It is no easy to find.

Hi Michele,

I am not an expect on the BACnet4J code, but I do try to dabble and help people a little when I can. But,

I think you cannot have an UnsignedInteger for a object with the type of AnalogInput. Looking in ObjectProperties suggests the following support a presentValue property set to the UnsignedInteger type:

ObjectType. accumulator command multiStateInput multiStateOutput multiStateValue positiveIntegerValue

So it sounds to me like you may be looking for,

systemStatus1 = new BACnetObject(localDevice, localDevice.getNextInstanceObjectIdentifier(ObjectType.positiveIntegerValue)); systemStatus1.setProperty(PropertyIdentifier.objectName, new CharacterString("System status group 1")); systemStatus1.setProperty(PropertyIdentifier.units, EngineeringUnits.noUnits); systemStatus1.setProperty(PropertyIdentifier.presentValue, new UnsignedInteger(65535)); localDevice.addObject(systemStatus1);

There is no requirement to get your application certified but in some cases a customer might require a BTL certification.
