Hi again,

I did the following simple circuit for test purposes and i like to have a display

about the remaining time before generator gives a high output.

The program works well but i need to know how many seconds remains until output goes high again.

Is it possible?

TIA

This is the real project.

A weakly timer opens and trigger a motor for 2 sec every 5 min.

When input I1 (which is terminal switch), closed, the latch goes to zero and stops the loop.

All i want to know is the remaining minutes until next motor triggering.

TIA

I do not understand exactly what you want, because I do not understand the meaning of your circuit.
You take the weekly timer, which turns on at 7:00 clock and off at 18:40 clock again. From the HIGH signal you form a positive edge, with which you turn on an RS memory. You switch the memory off with I1.
When the RS memory is switched on, an asynchronous pulse generator is running. If its output has HIGH signal, you turn on the output Q1 and the message text.

What time do you want to show now?
How long does it take for the pulse generator to switch back to HIGH?
Then you have to keep the message text active at all times.

 This is exactly what i want to do. I was wondering if it is possible somehow because it will help me a lot.

 Exactly like this. Thank you very much. We will talk again in a next question post.
