Data types
Not every data type supports all trigger types. The table lists the configurable data types and
specifies the supported trigger types for each data type.
The tag "Data type alias" (DATAPOINT_TYPE) specifies the data type of the transferred
values when publishing the user data to the cloud, see section User data format (Page 89).

Modbus data types
As standard, Modbus uses the data types "Bool" and "Word".
● The data type "Bool" is transferred from the application as "UInt8".
● The extended data types are transferred as 2 or 4 consecutive 16-bit registers.
