Menu Selection: Insert > Object > Global Data

The Global Data object provides a means for distributing information about changes in a single attribute value to other attribute reference points. This minimizes hardware costs and system complexity. For example, an NAE might have multiple AHUs on its network, but only one has an outdoor air sensor. The Global Data object can share the value from the single sensor with the other AHUs.

The data types defined for the Global Data object’s input and corresponding outputs should match. Otherwise, each output attempts to convert the value being received to the data type defined for it. The software does not check for data type consistency. Global data sharing is restricted to within one site.
