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.
When using other data types in the device and in downstream applications, you must map
and interpret the data read from the station in a user-specific manner.

Import tags

In addition to manual data point configuration, you can import the tag information using a file
exported from STEP 7 for S7 stations.
