I have adapted the bacnet4linux 'stack' to export analog and binary
objects to EPICS AI & BI records in a 'read-only' mode. The bacnet stack
runs as a separate linux application, and EPICS device support reads the
object real-time values (acquired using COV 'monitors') via IPC message
queues. I am presently working on exporting bacnet objects that generate
alarms and events, to EPICS PVs. This is work in progress, and is not
running as a commissioned system yet. Because of it's Linux centricity,
it will only run on a linux-hosted soft IOC
