Hi All, I have a remote BACnet device that is stuck on 'initializing.' It does not switch back and forth between 'initializing/uninitialized' it's simply stuck on 'initializing.' When I enable or disable the device an 'AddressSpaceNotRegistered' warning gets recorded in the logs. This remote device had been connecting fine. I've tried deleting and re-creating the device, restarting the BACnet module and even tried restarting the Gateway to no effect. As always, any help/info with this problem is greatly appreciated. _IG version 8.1.32_ ---

Is your BACNet device on the same subnet as your gateway? ---

No, it isn't. But I had been connected to it without issue. I've been using the '0.0.0.0' bind address successfully until today. I have multiple devices (all different subnets) still initialized/tags updating. ---

Been a few years since I connected BACNet devices but I had to manually update a device side file, like a routing table to get Ignition to connect. I believe the term was BBMD. Any possibility your device has changed? ---

No, I don't think so, but I will check. Thank you for the direction. ---

I took a peek at a working setup. In the setup, gateway is on a different subnet than BACNet device. Below is config of local device. BBMD was updated on device side to include ip address of gateway. Bind Address = ip address of gateway Broadcast Address = device ip BBMD Address = device ip Device Number and Network number were obtained from the BACNet side. ---

Ok, thank you. In my organization, a different group owns/maintains the BMS, so I don't know how much luck I'll have with changing their setup. I'll look into it though. Thanks again!
