Make sure the user I'm logged in to doesn't have read-only rights. You can find out either by setting the user rights vIDE or in the overview of individual pages on the terminal the symbol "crossed out pencil" is displayed for pages that are read-only.
Yes, you can download the uploaded terminal definition from the web interface. However, this is already a compiled definition, which can no longer be easily modified to get the original definition, which you can also edit, so it is necessary to have a project that you open in the Merbon IDE (note for older versions 220.127.116.11 and lower Merbon HMI)
Terminal settings must be logged in via a user with "Admin" rights or log in to the web interface in a web browser (default password is "rw"). Set the function "off" to "0".
