one button non latching relay with timer

Hi

I'm searching for the following program in FBD.

Situation : several puchbuttons are placed on ground ,second and third floor. They all share the input (I1) and they all switch the staircase light on or off after 2 minutes.

I1 = a push button

Q1 = the staircase light

When pressed on pushbutton I1 , the light switches on ,pressed once more the light goes off after 2 minutes. (impuls relay with a timer)

I want to add a characteristic of the button, namely when pressed the pushbutton for 2 seconds , regardless  the state of the output (light on or off) , The output has to stay on untill the pushbutton is switched once more.

Kind regards to you

P1 When pushed I1 for the first time , the timer before Q1 has to start running (Situation : Press the pushbutton on the staircase , climb the stairs , enter a room , light goes out after a preset amount of seconds)

P2 When pushed I1  for the second  the time (When timer is still running) , the  light goes out  (Situation : Press the pushbutton on the bottom of the staircase , climb the stairs , press the pushbutton on top the staircase ,the  light goes out, enter a room (reset the timer and brake the contact between timer and Q1)

P3 When pushed I1  for 2 seconds , the  light goes on  (Situation : When they want to do some work on the staircase , there has to be uninterruptable light ) When pushed again , the ligt goes out.

P3 works marvelously,

Kind regards

In the first post you wrote:

"When pressed on pushbutton I1 , the light switches on ,pressed once more the light goes off after 2 minutes. (impuls relay with a timer)."

As means to me:
First Press - Lights on
Second press - light off after the off delay.

Is this not what you mean?

Edit:
And I ask again: What logo it should be?

The Second program works like a charm
