Issue
BACnet COV subscription system
Product Line
EcoStruxure Building Operation
Environment
- BACnet Settings
- COV subscriptions
- v1.7 and earlier
Cause
A site will have a problem with the amount of traffic because of misconfigured COV Increments. The problem is that Building Operation, the ES and AS resubscribes to values every 10 seconds and one by one.
So for example:
hh:mm:ss 00:00:00 Value1 00:00:10 Value2 00:00:20 Value3 00:00:30 Value4 ... 05:00:00 Value1800
If you have more than 1800 subscriptions the ES or AS is not able to do all subscriptions in 5 hours. 5 hours is used because Building Operation subscribes to the values with a lifetime of 5 hours.

BACnet COV subscription system is not influenced by the requested transfer rate in the edit bindings...
