Issue
What is the limitation on the number of COV subscriptions an RP-C can handle?
Product Line

Environment
Building Operation Room Controller (RPC)
Cause
When setting up a binding to an RP-C to read a value from another device or transfer a value in the RP-C to another device COV subscriptions are often used.
Resolution
The number of subscriptions an RP-C can support is limited primarily by the available resources of the controller.
An RP-C with a single point can support thousands of subscriptions but that’s not a realistic configuration on a live site. If resources were allocated to support a defined number of COV subscriptions, this would lock down those resources (primarily memory), making less room for other applications.
Since the maximum number of subscriptions depends on how many available resources the controller has at the moment when a subscription is made, there is no guaranteed number on how many subscriptions an RP-C can support.
