You use the Add New Pens dialog box to add a new pen to your trend display. To display the Add Pens dialog box, click Add Pens on the main toolbar.
Adding a new pen:
To identify the item you would like a pen represent, you need to initially define a search to determine what is available. You can then select a particular item from the search results.
If you would like to add a new connection to the list, see Configuring Connection Properties.
To search a SCADA server:
The filters have basic wildcard and Boolean search functionality. You can use the keywords AND, OR and NOT with wildcard strings, as well as group Boolean terms using parentheses. Searches are not case sensitive.
For example, entering "L*" in the Tag Filter returns tags beginning with the letter "L" in every cluster. Entering "L* OR H*" will find tags beginning with "L" or "H". More complex examples include "L* OR (H* AND NOT *G). This would return tags that start with "L" or any that start with "H", but do not end in "G".
If you leave a field blank, each item of the selected type will be retrieved.
In the case of a SCADA connection, the results are not sorted: the tags appear in the order they were configured in CitectSCADA. The cluster associated with each tag is also displayed. The Process Analyst displays only the tags in clusters that this client has access to. In a system with more than one cluster, if a tag is not configured with a cluster, it is listed once for each cluster.
To search a Historian server:
The following example shows how wildcards can be used to search a path and attribute name.
If you leave the field blank, published attributes of the selected type will be retrieved.
Note: To remove a tag from the Selected Items list, highlight the item you want to move, and then click Remove.
