how can we define the data types while working in control builder. what exactly is the defining criteria?
All the AI/AO signal normally we will define Real signal and DI/DO signal will be Bool.
While creating the application in control builder if data type is not matching it will show the error and you can check the data type by simply click the F1 on any function block.
Hope it will help you.
Please study the different data types, the predefined structured data types (RealIO, BoolIO, etc) and how to create own structured data types in the following user's guides:

- System 800xA Control AC 800M Configuration User's Guide (3BSE035980-510)
- The Control Builder M On-Line Help (press F1...)
After reading the above material, please refine your question and I will try to answer it as best as I can or redirect you further.
