-There is the possibility of external access to the WebHMI registers via the Modbus / TCP protocol. To do this, go to the menu **Configuration -> Modbus / TCP server**. If you specify the option Export in the list for registers, this register can be accessed externally via the Modbus / TCP protocol, with the address entered in the **ModBus / TCP Address**. The address format is a value from 0..65535. In this case, it's not about the address of the Modbus data model (for example 40001-49999 for holding registers), but about the address in the modubs telegram(PDU address).
