Echelon OpenLNS - Manual (Page 567)

OpenLNS Programmer's Reference 530
EventInterval property expires, OpenLNS will not call the
GetNextEvent service right away. Instead, it will wait until
the next event (or set of events) occurs, deliver that event to
the client, and then immediately call GetNextEvent (because
the interval has already expired). Following that, OpenLNS
will call the GetNextEvent service at the interval defined by
this property.
Note that as you set this property to lower and lower values,
more and more request-response messages will be sent to the
server. You should keep this in mind when setting this
property, as it may cause more network traffic than you
desire.
This property is not applicable to Local Client and Full Client
applications because the OpenLNS Server delivers events to
those clients as soon as they occur. However, you can change
the default value used by all of the Lightweight Clients on
the network by changing the value of this property on a Local
Client. By changing the value of this property on a
Lightweight Client application, you change the value used by
that client only.
Availability Local, full, and lightweight clients.
Syntax eventInterval = networkObject.EventInterval
Element Description
eventInterval The period of time that has passed
since the last event request.
networkObject The Network object to be acted on.
Data Type Long.
Read/Write Read/write.
Added to API Prior to LNS Release 3.0.
Extensions
Summary Contains the Extensions collection object associated with the
specified Network object.
This property returns an Extensions collection. The objects
in this collection represent user data reserved for
manufacturers. Each object is identified with a unique
identifier set by the manufacturer.
Note: The
Extensions collection for a Network object is stored
in the specific OpenLNS global database computer, and it is
not exported with the Network database. As a result, the
collection would be lost in the process of transferring a
network database from one computer to another.
Availability Local, full, lightweight, and independent clients.
