The LCD display does not connect to the RT

If I want to upload the menu on the IPLC510 display, it must have a localhost address in the connection properties in the HMI Editor in the form (Variable… manager -> Connection -> Update / Edit connection -> Remote -> Address ->, ie default settings in the project. If a real address is used, eg, then after connection everything works until the Ethernet cable is disconnected. When the cable is disconnected, the display does not connect to RT ("does not find this address") and RT does not respond to changes from the display.

Therefore, do not change the default address (localhost) to a specific IPLC address.
