classIdValue

The object class of the object. The

following value is defined for the

NetworkResources

object in the

ConstClassIds

constant:

93 lcaClassIdNetworkResources

object

The object to be acted on.

Data Type

Integer.

Read/Write

Read only.

Added to API

Depends on the object used to access the property. Generally,

this property exists for an object as soon as the object is

added to the API.

ExclusiveSelectorPoolSize

Summary

Indicates the total number of exclusive selectors in the

system, including those that are already being used by

connections. Typically, this value will be set to 11,264

.

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.
OpenLNS 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 determine exactly how many exclusive selectors

have not been assigned, and are still available, by reading

the ExclusiveSelectorsAvailable property.

Availability

Local, full, and lightweight clients.
