to the value of the network variable, without creating a monitor point to represent the
network variable.
This chapter describes the LNS features you can use to perform these monitor and
control operations. Table 9.1 describes each section included in this chapter. Echelon
recommends that you review the entire chapter before developing your application, so
that you are aware of all the monitor and control capabilities LNS provides.
Table 9.1 Monitor and Control
Section Description
This section describes the major differences
between temporary and permanent monitor sets.
This section describes how to create a temporary or
permanent monitor set.
This section describes the initial steps you need to
take to use a monitor set for monitor and control
operations after you have initially created it. This
includes the following:
1. Add network variable and message monitor
points for the devices you plan to monitor to the set.
2. Define the monitoring options for the set.
This section describes the steps you need to take to
open a monitor set and enable it for monitor and
control operations.
This section describes several ways you can use
network variable monitor points to monitor and
control a network.
This section describes how you can use message
monitor points to monitor and control a network.
This section provides guidelines you will need to
follow when writing remote applications for monitor
and control.
This section describes how the system management
mode impacts the behavior of some monitor and
control operations.
At some point, you may want to read or write the
value of single network variable without monitoring
its value beforehand. You can do this by directly
reading or writing to the value of the network
variable through a DataPoint object, without
creating a monitor set. This section describes how
you can do so.
