Enter the scan interval to be assigned to the device (default is 1000). The scan
interval is the target time in milliseconds at which the current device will be scanned;
it is the scan time which could be achieved under optimal circumstances. This will
vary greatly from network to network, depending upon the number and type of
devices being managed, the amount of data being requested by the client
applications, and even the architecture of the network itself. The valid range for scan
interval is 1 to 9999999; scan intervals less than 100 milliseconds are usually
impossible due to network timing constraints.
Clicking OK accepts the entries and returns to the Device Configuration dialog box.
Modify
Select the device (topic) to be modified and click the Modify button. The Modify
Device Configuration dialog box will appear. The options and fields in this dialog
box are similar to those in the Add Device Configuration dialog box. Make any
necessary modifications and click on the OK button. The modified information is
reflected in the Device Configuration dialog box.
Delete
To delete a device (topic), select it and click on this button.
Activate checkbox
At the bottom right of the Device Configuration dialog box, you'll notice a check
box labeled Activate. This box provides a one-step way to turn a device on or off at
the Server. Make sure this box is checked for each device; devices which are not
Activated will not communicate with the Server. Conversely, for troubleshooting
purposes, you can use this checkbox to quickly take a device off-line.
