Viewing the Data - OPC Clients
Once the AscentOPC server is running, anyone with an OPC client on their PC can connect to the server to view machine data. There are many OPC clients available that can be used to connect to the AscentOPC server e.g. CitectSCADA. Your Distributed Control System administrator will be able to advise you on the most practical OPC client for your needs.

Viewing Data in List or Navigator Tree Style
OPC clients can browse the AscentOPC data using a navigator tree-style display rather than a listing of all items. The 'Hierarchical Browsing' option allows clients to see a view of the data similar to the Ascent navigator tree structure i.e. clients can click on parts of the tree structure to open out the machines, points and measurement locations.
Example OPC client viewing data using hierarchical browsing
- To display data using a navigator tree-style, in the AscentOPC program select Options>Hierarchical Browsing. Deselect this option to display items in list-style.
Notes:
Because the display of data is controlled from the server program all connected clients will see their data according to the option selected here (tree or list style).
Browsing options can only be changed when no clients are connected (if clients are connected the software will display a prompt advising you of this restriction).
