Tag names cannot contain spaces. The tag name can be mixed case. Tag names preserve
upper and lower case for readability but are not case sensitive. For example, the tag name
MixerValve1 is the same as mixervalve1.
When a tag name starts with a number or contains a dash, enclose the name in curly
brackets { } when you use it in an expression, for example, {N33-0}. For more
information about using tags in expressions, see Chapter 23.
Use folders to group tags
To organize tags, create a folder to store tags that are related to one another. To separate
the folder name from the rest of the tag name, use a backslash (\). For example, tags in the
folder called Pump would start with Pump\.
For greater organization, you can nest folders. For example, you can organize the HMI tag
database first by area, then by machines in the area, and finally by devices in each
machine. The result might be Area1\Machine1\Pump.
To create similar groups of tags quickly, create one folder with its tags and then duplicate
the folder.
View tag statistics
The Tag Statistics dialog box provides a summary of how many tags your application
uses, as well as other tag information such as the date the HMI tag database was last
modified. To view tag statistics, the Tags editor must be open and have focus.
