MsgMonitorPoint
A MsgMonitorPoint represents a single monitored or controlled message tag. You can use
message monitor points to monitor L ON W ORKS messages from application devices on your
network with your application. For an overview of message monitor points and how they
work, see the Monitor and Control chapter in the OpenLNS Programmer’s Guide.
In general, the MsgMonitorPoint objects contained in MonitorSet objects created as
temporary or permanent monitor sets behave the same way except that the DefaultOptions
properties of the MsgMonitorPoint objects in temporary monitor sets are not accessible. For
more information on this, see the CurrentOptions property of this object.
Temporary monitor sets, and all the monitor points they contain, can only be used in a single
client session. They are deleted by OpenLNS as soon as the session in which they were
created ends. For more information on the differences between temporary and permanent
monitor sets, see the MonitorSet object .
