Running Projects in Operator Mode

Operator mode provides a way to disable editing capabilities for LabVIEW SignalExpress projects. Disabling editing capabilities can be useful if you want to distribute a project to other users. For example, if you create a project that generates a signal, you can configure the project so that in operator mode a user only can adjust the frequency of the signal. You also can use operator mode to create an interface with a limited set of controls that is easy to use and learn.

You can set a password on a project so that a user must enter the password to disable operator mode. If you save a project in operator mode, the project always opens in operator mode unless you save the project again with operator mode disabled.

If you want to allow a user to change signal values on a project in operator mode, you must create an operator interface. An operator interface contains controls that you bind to specific step parameters so that in operator mode, changing the value of the control changes the value of the step parameter. Use the Operator Interface view and the Toolbox and Properties windows to create an operator interface.

Note  If you save a project in operator mode, LabVIEW SignalExpress saves the project with its initial signal values, regardless of whether you change the value with a control.

After you configure a project with an operator interface, select Operate»Operator Mode»Operator Mode Enabled or click the Operator Mode Enabled button on the Operator Interface view to enable operator mode. When a project is in operator mode, only the Run and Record buttons appear in the toolbar, and a limited set of menus and menu options are available. You cannot display any additional tabs or views when a project is in operator mode, and you cannot add, delete, or configure steps. Configure LabVIEW SignalExpress to display all the tabs, views, and steps you need before you enable operator mode.

If a project is in operator mode, selecting Operate»Operator Mode»Operator Mode Enabled or clicking the Operator Mode Enabled button on the Operator Interface view disables operator mode.

Setting an Operator Mode Password

Before you enable operator mode, you can specify a password that a user must enter to disable operator mode. Select Operate»Operator Mode»Set Operator Mode Password or click the Set Operator Mode Password button on the Operator Interface view to set an operator mode password. When you save the project, LabVIEW SignalExpress saves the password with the project.

Note  LabVIEW SignalExpress does not encrypt operator mode passwords. Use operator mode passwords for simple access control.
