OPC Data server properties (Advanced tab)

In the Advanced tab you can create a cache of the data server’s tag names, and choose whether to include additional tag information, such as tag data types, in the cache. Creating a cache lets you browse for tags when the server is not available.

To create a tag cache for a data server

  1. In the Explorer window, right-click the data server icon and then select Properties from the Context menu.
  2. On the Advanced tab, click the check box labeled Include extended information in the server cache file if you want extended tag information to be available in the cache.
  3. Click the Create Cache button to create the cache. If the cache already exists, the button caption will be Synchronize and the button will allow you to update the cache contents.

Options

  • Include extended information in the server cache file

    Click this check box to include extended information. Including extended information will increase the time needed to create or synchronize the cache.
