Issue
SpaceLogic IP device is located in a remote subnet and EcoStruxure BMS server can't discover it.

Cause
BACnet broadcast messages, such as Who is/I am that are used for device discovery, will not be forwarded between the two IP subnets. BACnet Broadcast Management Device (BBMD) is required to allow BACnet to operate through IP routers.
Resolution
Scenario 1:
SpaceLogic BACnet/IP device is located in remote subnet with no EcoStruxure BMS server or BBMD located in same subnet. EcoStruxure BMS server will be configured as BBMD, and SpaceLogic BACnet/IP device will be configured as foreign device and register itself with BBMD (which is the AS-P in our example).
The following video will illustrate how to:
- Configure SpaceLogic BACnet/IP device located in foreign IP subnet as a foreign device.
- Configure an EcoStruxure BMS server as BBMD.
- View foreign device registration on the EcoStruxure BMS Server.
- Discover and host the SpaceLogic BACnet/IP device.
Scenario 2:
SpaceLogic BACnet/IP device is located in remote subnet with a 3rd party device that can be configured as BBMD. In the other subnet, EcoStruxure BMS server will also be configure as BBMD. SpaceLogic IP device will not be configured as foreign device as there is BBMD device in the same subnet. This BBMD will redistribute the essential broadcast messages to it. Once configured, EcoStruxure BMS server will be able to discover and host the SpaceLogic BACnet/IP device and other BACnet deviced located in the remote subnet.
The following video will illustrate how to:
- Configure SpaceLogic BACnet/IP device located in a remote IP subnet.
- Configure an EcoStruxure BMS server as BBMD.
- Configure Broadcast distribution table (BDT) in EBO.
- Use BACnet browser to check and verify the BDT configuration of a 3rd party BACnet device.
- Discover and host the SpaceLogic BACnet/IP device and 3rd party BACnet devices located on remote subnet.
