When it's booting up, do you get a selection window where you can select: Start, Setting, Download? If you do, press settings and look from the HMI settings what is the MPI address or IP address.

See the following link: How do you do an operating system update on operator panels or perform a "Reset to factory settings"? Best regards, Wizard
