So I'm working on a trial mango install at an existing site (currently running Alerton Envision 2.6), with mostly Alerton hardware. Upon setting up the BacNet datasouce, and enabling it, it sends out a who-is, and gets back responses from only 4 devices, 3 of them the York chillers, connected via MS/TP from an Alerton BCM that doesn't respond.
Anyway, regardless of the lack of response the rest of the massive site is giving me, which I'll look into later, I'm wondering about how point setup should be done. Lets say, for example, i want to set up AV-8409 on a BacNet/IP device (instance 430). I set the point up as follows:
Device instance: 430
object instance 8409
Use COV: unchecked
When doing this, it never polls the point - in fact, it never even sends out a who-is to find device 430. If I set up a point that is on one of the devices that DID successfully respond to the initial who-is, it works. Is this a limitation of the bacnet implementation? If it doesn't already have an idea of how to find a given device, shouldn't it ask?
I am running the mango server on ubuntu inside a virtualbox vm, and monitoring the traffic with Wireshark on the windows host.
