A Modbus subsystem uses the underlying Modbus Driver from WinCC OA. It uses Modbus protocol
over TCP. During import, the field engineer has to specify the IP Address and the port number for
communicating with the device. If the port number field is left empty, then the Modbus Importer
applies the default value: 502. However, after the import, the user can modify both IP address and
port number from the Desigo CC client.
