MODBUS requests can be managed within a library. The library contains modules. Each module refers to a MODBUS request with it´s function code and size.

Each module may contain variables representing MODBUS items (bits or words). Multiple modules can be grouped into "devices".

The library will be saved in XML format.

Hint: The dialog is available only, if the library is not empty. Please ensure that an XML file has been uploaded before.
