Use the Filter pane to reduce the tags listed in the Tags pane according to criteria that you specify. You can filter the tags according to name, description, and I/O address.
The filter mechanism allows for the following wildcard characters as part of the filter criteria:
|
Wildcard Character |
Filter Function |
|---|---|
|
% |
Any string of zero or more characters. |
|
_ |
Any single character. |
|
[ ] |
Any single character within the specified range or set. For example:
|
|
[^] |
Any single character not within the specified range or set. For example:
|
For example, to find all tagnames ending with "level", type %level. Filter criteria are not case-sensitive.
When the Servers pane and the Filter pane are both visible, the filter conditions apply to the selected group in the Servers pane. When the Servers pane is hidden, the filter applies to all of the tags for the selected Historian.
To apply a filter
-
In the Server box, select the server.
This box is not available if the Servers pane is visible.
-
In the Tag name box, type the string to match for the tagname.
-
In the Description box, type the string to match for the description.
-
In the I/O Address box, type the string to match for the I/O address.
-
Select the Exact match check box to search for tags that exactly match the entire string that you provided for the tagname and description options.
For example, if you specify "level" as the tagname and do not select Exact match, any tagname that contains the string "level" appears. For example, "ReactLevel," "ProdLevel," and "$AccessLevel."Note: The Exact match option does not apply to the I/O address.
