Displays the current HMI access rights. An application can have one of the following modes:

  • Human Machine Interface Read/Write mode

    This is the default mode when opening an application.

HMI R/W mode

  • Human Machine Interface Read only mode.

    This mode is active in the following cases:

    • Applications are opened in Read Only mode by selecting the option Open the project in read-only mode in the open file window.

    • Opening an application previously opened in write mode with a third-party software (using Pserver). A pop-up window alerts the user at the opening.

    This mode does not allow to save the application.

    When using third-party application with Pserver, Control Expert can be launched without the Control Expert graphical interface (called Human Machine Interface). In this case, a dialog box prompts the user if it should switch on the current PServer Instance.
