I have a few related questions with regard to using BACnet IP in the recent releases of Mango.

1. How should the BACnet Local Devices be set up in a system operating across multiple subnets? Should there be a Local Device set up for each BBMD or is there no correlation between the two concepts? In the older versions of Mango I was able to discover a large number of our devices across multiple subnets with the data source set up with a Device ID of 0, a Broadcast Address of 255.255.255.255 and a Port of 47808. I have been unable to find a Local Device and Data Source setup under the newer versions that discovers nearly as many devices.
2. Autodiscovery seems to work to a limited number of devices across subnets. Using a local Device of 0.0.0.0:47808 Mango always discovers exactly the same 115 devices almost instantly and then never discovers anything else. With all the other Autodiscovery tools we use (including the one in the older version of Mango) we find many more devices on our network but it takes several minutes for them all to report in. Does anybody know why this should be so different?
3. How does the MAC relate to the older concepts of IP, Port, Network Number, Network Address and Instance Number. Working with our commercial BACnet providers, I was able to relate this older terminology to concepts they were familiar with. But, while I have found some references to a MAC in the literature, I have been unable to determine how that relates using real world BACnet systems from companies like Johnson Controls, Automated Logic, Delta, Siemens, etc.
   Thanks for any help.

I have the same question. I want to check on an interval but only record a new value if the value of the field point has actually been updated. I don't want to record a value if communication has been lost to the field point over the interval period.

Is there a guide to define the new BACnet terms used in Mango 2.5? We were able, with some difficulty, to discover and add points in the older versions of Mango. But this has us stumped. Unfamiliar terms not discussed in the Help include:
Local Bind Address (System Settings)
Broadcast Address (System Settings) . Is this any BBMD or does it have to be in the same subnet as the Mango Instance?
MAC (Data Source Remote device object list)

Has there been any movement in including this as a module in Mango Automation (ie M2M2) since the last post?
