98 Designing Networks
• To create a dynamic variable from the template of an existing network variable in your
LonMaker drawing, select Derive from Existing NV under the New NV Type box and
then click Browse. The Select Object window opens. Expand the listed objects to view
the network variables in your LonMaker drawing. Click the network variable you want
to use as the source for the dynamic network variable. Click OK.
4. Click More if you want to set the polling attributes for the dynamic network variable(s) you are
creating.
5. Under Poll Attributes of New NV(s), select whether the dynamic network variable(s) will by
default use polled monitoring. You have four choices:
• Select Clear to disable polling.
• Select Set to enable polling.
• Select Same as Source NV to use the same poll attribute of the source network variable
(enabled or disabled). This option is only available if the dynamic network variable you are
creating is derived from an existing network variable.
• Select Opposite of Source NV to use the opposite poll attribute (if the source network
variable has polling enabled, the dynamic network variable will be non-polling). This option
is only available if the dynamic network variable you are creating is derived from an existing
network variable.
6. If you the dynamic network variable you are creating is based on a defined type, you can also
select whether connections with the dynamic network variable use Acknowledged, Repeated, or
Unacknowledged messaging service,
and you can enable priority and/or authenticated messaging
on the connections. See Connection Description Properties later in this chapter for more
information on messaging service types and options.
