Chapter 8. Properties Window

This first option in the Properties Window lets you control how changes to data are transmitted from the Cascade DataHub.

Data Changes

Do not transmit insignificant changes will reduce traffic by allowing only significant changes to the data to be sent.

Do not transmit changes with an old timestamp allows only current or future changes to be sent.

Automatically add a timestamp to unstamped changes stamps the current time onto any changes that haven't already been time stamped.

This should stay checked unless you have specific reason to uncheck it. Unchecking it may cause changes made through DataSim, the Data Browser, and other programs to receive timestamps of 0 (Dec 31 19:00:00:00.000). If this button is unchecked and the Do not transmit change with an old timestamp is checked, then any changes with a 0 timestamp won't get transmitted at all.

Startup

Show the splash screen at startup lets you hide or show the startup screen with the DataHub image.

Show a warning message if running in demonstration mode lets you hide or show the message telling you the demo will terminate in one hour.

Start when Windows starts causes the DataHub to start up whenever you start up Windows.

Declare these data domains

In this area you can add, edit, or remove data domains for the Cascade DataHub. For more information abpit domains, please refer to Section 2.4, “Data Organization”.

To add a domain, click the Add button and fill in the name in the Domain Name Window:

To change a domain, double-click it or select it and click the Edit button. To remove a domain, highlight it and click the Remove button.

Checking the Automatically add domains requested by clients box automatically adds a domain whenever a client requests it. If for some reason you want to limit the domains to those listed, you should make sure this box is not checked.
