User-defined Types
This section includes:
• User-defined network variable types
• User-defined configuration property types
These user-defined types have been created by Trane™ for use by Trane controllers. In
many cases, the Trane user-defined types contain standard network variable types
(SNVTs) to make them easy to understand.
