I have key code protected settings pages on all our touch panels in our classrooms here at Dalhousie University.

?

I am using:

Password Logic (fixed pwd) (cm) module

OR gate

Simple_timer_v1_0_1 (cm) module

?

Create a start page. When pressed it will take you to a keycode page with the Simple Keypad (Smart Object ID=1):v1 you add in your VTPro layout.

?

Have the keypad numbers and CLR go to the inputs on the Password Logic (fixed pwd) (cm) module.

Have them also go to an OR gate.

Have the touch panel start page press also go to the OR gate. This starts the timer and brings up the keycode page.

?

The panel-change output of the Password Logic module (Key Code Accepted) will go to the cancel input of the simple_timer module.

The output of the OR gate (Keypad Activity) will go to the start input of the Simple_Timer.

The timer_active output of the Simple_Timer (Code Page Activated) will activate your keycode subpage so the user can input the password.

The output of the Password Logic module panel-change (Key_Code Accepted) will also go to an Analog Initialize module to activate the page you wish the user to get to after entering the correct password.

?

Theory of operation:

User touches anywhere on the screen of the touch panel.

A user keycode page with a keypad pops up.

If the user does nothing, the page reverts back to the start page after 6 seconds.

While the user is entering the pass code numbers, the keycode page will stay active.

If the password is entered correctly, the user is taken to your preferred landing page.

If the password is entered incorrectly, nothing happens, they have the opportunity to clear and try again or after 6 seconds of inactivity, the keycode page reverts back to the start page.

?

The Password Logic Module has the following parameters:

TPID: ID number of the panel you are using.

TPFIELD: the join number of the indirect text display, if using.

PASSWORD: the numbers you wish to use.

?

The Simple Timer has the following parameters:

TIME: 6 seconds

?

Hope this helps.
