Cause

Concerned about large BACnet sites and exceeding a limitation on the number of BBMDs and Foreign Devices that can be registered. 

Resolution

The maximum number of BBMDs that can be registered on a bCX4040 or on a CyberStation is 32.

The maximum number of Foreign Devices (FDs) that can be registered on a bCX4040 or on a CyberStation v1.93 or below is 64.
