Recently i had to restore a MP377 panel 'reset to factory settings' now i have to reinstall the key on the hmi. does anybody know which license key i should ask for?
well what is strange is if i run the hmi project in wincc runtime i can log into all levels of access to the hmi. but if i download project to Mp377 it will not let me log in to the levels.
If it is the passwords for the users you are talking about make sure to check "Overwrite user administration" when downloading the project to the MP panel.
