4 Mode of operation
Menu – Jumping back to initial screen of the message texts
4.2.2
If you reach the final message text (output) with the function key [F4] and then
press [F4] again, the counter [B106] is set. The subsequent OR block [B107]
forwards the signal to the OFF delay [B010], here set to one second.
The subsequent marker [M1] is required to return the signal of a string to an input
of the same string, in this example the reset inputs of the counters. This resets all
counters and restarts the menu navigation from the initial screen.

As soon as one of the function keys on the LOGO! TDE is pressed
OR block [B108] and the switch-off delay [B109] switches the backlight of the
LOGO! TDE display to white [M26].
The subsequent block [B110] (NAND with flank evaluation) sends a pulse to the
reset inputs of all counters as soon as the switch-off delay [B109] preset time has
elapsed. In the example, the message text display returns to the initial screen after
one minute of inactivity.
