BACnet is an ASHRAE (& ISO) standard to automate building controls (building as in commercial buildings, residential flats, etc).

Wikipeda article here. Summary taken from there.

BACnet is a communications protocol for building automation and control networks. It is an ASHRAE, ANSI, and ISO standard protocol.

BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control, lighting control, access control, and fire detection systems and their associated equipment. The BACnet protocol provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform. Proper communication between building automation devices is critical for maximizing building energy efficiency, indoor air quality, and other aspects of "green" buildings.

In BACnet VTS scripting is there a way to implement functions/macros?

In my VTS scripts almost all the SEND, EXPECT commands have similar parameters(Like DEST ADDRESS, DEST NETWORK etc). So is there a way to avoid duplication using a function or macro. I had not seen any functions/macros in the example scripts of VTS.

Is there any way to test bacnet using IPv6 with node

Has anyone used node to test bacnet over ipv6. I'm able to use node-bacnet to verify it via IPv4 with no issues but it does not seem to handle IPv6. I don't see any other packages that will work with IPv6 but maybe I'm missing something.
