Plant SCADA places some restrictions on the names you can use for variable tags:
-
Tags names need to adhere to specific syntax (see Tag Name Syntax).
-
There is a set of reserved words that you need to avoid when naming a tag (see Reserved Words).
-
Do not give a tag the same name as a Cicode function that is used within the project or its included projects. A compile error message will occur if a tag has the same name as a Cicode function and is placed on a graphic page.
You can reference variable tag names (as a string) in your project, using the following formats:
-
<tag name>
-
<cluster>.<tag name > (used in multi-cluster systems).
Note: If your Plant SCADA project incorporates an equipment hierarchy, you may need to include a location in the hierarchy when you refer to a tag. This is reflected in the tag reference by using a period (.) to indicate levels in the equipment hierarchy (for example, "Plant.Line1.Pump.Tag1"). For more information, see Equipment Hierarchy.
