Echelon OpenLNS - Manual (Page 509)

OpenLNS Programmer's Reference 472
IsOpen
Summary Indicates whether the specified object is currently open.
You can open the
MonitorSet object with the Open method,
and you can close it with the Close method.
When you create a MonitorSet as a temporary monitor set,
OpenLNS automatically opens it. Once a temporary monitor
set is closed, it will be deleted
Availability Local, full, lightweight, and independent clients. Note that
temporary MonitorSet objects are not available on
Independent clients.
Syntax isOpenFlag = Object.IsOpe
Element Description
isOpenFlag Boolean value.
Object A Boolean value indicating whether the
MonitorSet object is currently open.
TRUE. T he MonitorSet object is
currently open .
FALSE. T he MonitorSet object is
currently closed .
Data Type Boolean.
Read/Write Read only.
Added to API LNS Release 3.0.
IsPollingEnabled
Summary Indicates whether polled monitoring is enabled for the
monitor set .
When polling is enabled for a monitor point, OpenLNS will
periodically read the value of the monitor point and report
the value using the OnNvMonitorPointEvent. This is most
efficient when the value must be checked regularly, but the
application does not need to know immediately if the value
changes (for example, outside air temperature).
You can automatically start polled monitoring of a monitor
set by setting the doEnable and doPoll elements to True
when you open the set with the Open method. You can also
start polled monitoring of a monitor set by setting the doPoll
element to true when you enable the monitor set with the
Enable method.
Availability Local, full, lightweight, and independent clients. Note that
temporary MonitorSet objects are not available on
Independent clients.
