Are there any plans to support BBMD in BACnet4J?

Thanks.

Matthew,

I'm getting an exception in seroUtils.jar. Near as I can tell it occurs when there are multiple concurrent requests for values for several different slaves. The exception stack is:

java.io.IOException: Stream closed.
at java.net.PlainSocketImpl.available(PlainSocketImpl.java:434)
at java.net.SocketInputStream.available(SocketInputStream.java:217)
at java.io.BufferedInputStream.available(BufferedInputStream.java:381)
at com.serotonin.io.InputStreamListener.run(InputStreamListener.java:67)

The only way it appears I can correct the problem is to restart the application and everything will work fine so long as I don't hammer the requests concurrently.

Have you seen this before?

The version of Modbus4J is 1.02.

Regards,
Fred

You can contact Serotonin for information about how to license the products in a more LGPL kind of way.

If it's any consolation, the ANT scripts in the repo are what i use to create the builds, so you'll get from that exactly what you'd get from me.

Ah, I got it. Similar to the quality property in OPC.

Thanks.

Ok, I was looking for support pretty much from the slave side only. I assume that would just be to relax the offset validation in the ProcessImage class. I'll try that and see what happens.

Thanks.

I thougth that the the whole thing is there, to add new DataPoints to RT if the RT is polling the dataPoints.
with the lock only one Thread can access the add/Remove or pointList.

I have a lock for the addList (the addList) one for remove and one for the pointList.
so adding will lock only the addList ...
If I copy over I must lock all.

This forum is for discussions around the Modbus4J product, which is used in Mango, but otherwise no associated. It is possible to get Mango to act as a modbus slave, but not trivial. If you need this, please use the contact page to request a quote.

Hi Fred,

That's a good question. I don't believe there are any specified requirements in this regard.

But when we look at the WhoHas service, there is a device id range (meaning your device id should be consistent), and there is a Choice object which can be either object identifier or name. So, theoretically either should do, but for maximum compatibility they should probably both remain the same for your object.

I guess what I really need to do (if it's not cost prohibitive) is get a hold of some of the BACnet monitoring tools and see how folks monitor and administer BACnet devices. I would guess the configuration of a hard wire BACnet device rarely changes and one can form dependencies on the object ids. If I need to maintain the mapping between my analog sensors and an arbitrary object instance id, I can do that - I just don't know if it's necessary.

Regards,
Fred
