Error during loading - Connection interrupted

JoseRmz

Good day! Working with TIAv13 and a HMI KTP 1200 DP PC adapter usb 6es7 972-0cb20-0xa0 I´m trying to download a proyect into a HMI, it compiles and identifies the device correctly but when clic on "Load" an error appears: "HMI Runtime error - Error during loading - Connection interrupted" -HMI "Transfer" option on enable and automatic -I checked the parameters for Profibus interface on "PG/PC interface..." and compared them with HMI, it seems the same but "Min. Tsdr" on HMI is "11" and "PG/PC interface..." is "12" -Change some Profibus parameters to make the same on PC and HMI, but it failed -Tried to download by MPI and same error appears Recently got contact with suport and said I have to check if "Transfer option" is enabled or my PC have a Profibus port Do you have any suggestions? Regards José Edit1 (25-Feb-2020): Suport just contacted me, they suggested to get "USB PC adapter A2" - 6GK1571-0BA00-0AA0. This week I´m going to get it and do some tests

 

Hola José, tuve exactamente el mismo problema. Tengo el Tia Portal V13 instalado y trataba de programar una pantalla TP700 mediante el adaptador USB-MPI. 

Aparentemente como la pantalla vino con el Firmware V15.0 no se puede programar directamente por interfaz MPI desde el TIA V13. Entonces probé programar la pantalla a traves de la interfaz ethernet y automáticamente se hizo un Downgrade del Firmware de la pantalla a la V13.0, luego se continuó cargando el programa correctamente.

Hecho esto, ahora sí puedo programar el panel mediante la interfaz MPI.

Saludos y suerte.

Gabriel.
