ExclusiveSelectorsAvailable
Summary Indicates the total number of exclusive selectors that are
currently available in the system .
A network variable selector is a 14-bit number used to
identify connected network variables. Each connection in the
system is assigned a selector value, and all network variables
in a given connection must use the same selector.
Intersecting connections must also use the same network
variable selector. OpenLNS can also share network variable
selectors among unicast connections if those connections are
between disjoint devices. Network variable selectors that are
shared between unrelated connections come from the pool of
sharable selectors available on the system.
LNS assigns exclusive network variable selectors to sets of
intersecting connections, and to each connection that
contains multiple targets. The selectors used to form this
type of connection are called exclusive selectors.
You can find out how many exclusive selectors exist on the
system (including those that are already in use) by reading
the ExclusiveSelectorPoolSize property.
