Opens a reference to a tag on the server. If no reference of the tag exists on the server, the node creates one.
Connection to the server.
If you leave this input unwired, this node uses the default connection. It automatically retrieves your SystemLink Server credentials when you execute the application on a managed system or server.
Data type of the tag reference.
If a tag with the same path but different data type already exists, Open Tag returns an error. Use Query Tags to open existing tag references of unknown data types.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Tag the server references to communicate measurement data.
Error information.

To set tag permissions for a group of tags or query a collection of tags, use an asterisk to match any sequence of zero or more characters in a tag path. For example, to return every tag that begins with example.path on the web server, enter example.path* in to the path input.
