Since you more than likely want very fast response, the temptation is to set the Update
Interval to a value close to 0 seconds. However, if every point is polled at this rate, the
entire system will suffer due to slow response time. Therefore, you should compromise,
and set the Update Interval to a more reasonable value. You could also create multiple
device groups for each device, setting the Update Interval to different values, then
assigning different items to different device groups depending on how quickly the values
change and how quickly you want to see an update of those changes.

Some items, like alarms, change very infrequently but because of their importance
require very fast updates. For those kinds of items, you should set the Update Interval at
a very small value. If you desire an immediate response, set the Update Interval at 1.

Archiving Configuration Sets
After you have configured your DAServer, you can archive that specific configuration. You
can archive more than one configuration set, and subsequently choose different
configurations for different purposes.

To archive configuration sets
1. In the DAServer Manager, right-click on the Configuration node in the hierarchy below
your DAServer.
2. Select Archive Configuration Set from the shortcut menu.
3. In the Archive Configuration Set configuration view, provide a Configuration Set
Name.
4. Click Archive.
All current configuration values are saved to the archived set.

Once you have archived at least one configuration set, you can select it for use.

To use different configuration sets from the current one
1. Make sure the DAServer is not running.
2. In the DAServer Manager, right-click the Configuration node in the hierarchy below
your DAServer.
3. Select Use Another Configuration Set from the shortcut menu and click on a
configuration set in the sub-menu.
All parameters in the DAServer configuration hierarchy change to the chosen
configuration set.

Configuring Device Item Definitions

The Device Items tab in the Parameters configuration view is used to define aliases to
actual PLC items. The Device Items dialog box is the place where the following activities
are performed:

Creating new device item definitions for PLC items.
Modifying the existing device items.
Deleting device items.
Archiving the created list of device items to a .csv file, a file with values separated by
commas.
Bringing a .csv file into the Device Items tab.
