Controlling a controller which contains a program protected by a password via the buttons on the front panel

If a user program protected by a password is loaded in the controller, it will no longer be possible to access the main menu by pressing the OK or ESC buttons. The screen below appears instead of the main screen:

To enter the password, simply select the "0001" field and modify using the buttons. If a password is required, the user has 5 attempts to enter the correct password using the + and - buttons. If the correct password has not been entered after these 5 attempts, the user must wait 30 minutes before restarting (if the cycle time is equal to 10 ms and the power has not failed). Once the correct password has been entered, pressing OK will open the main menu.
