Adding Data - The Application Data Object
According to the Anybus object model, all data that is used in the application must be represented by application data instances (ADIs). ADIs are small portions of structured data, each representing only one of three possible different types: variable, array or structure.
See the Application Data Object (FEh) in the Software Design Guide for more information.
Below is an example with 30 ADIs. Instances 1 - 6 and 30 are implemented in the application, and 7 - 29 are not implemented.
Table 1. Application Data Object (FEh) Instances
Instance # | Implemented | Order # |
|---|---|---|
1 | Yes | 1 |
2 | Yes | 2 |
3 | Yes | 3 |
4 | Yes | 4 |
5 | Yes | 5 |
6 | Yes | 6 |
7...29 | No | - |
30 | Yes | 7 |
