Technical support / continuous cycle timer

« on: October 07, 2008, 02:08:08 AM »

Hi
I am trying to turn on OUTPUT1 for 5 seconds when a START button is pressed, after which , OUTPUT1 will then be turned OFF and OUTPUT2 will then be turned ON for 10 second then turned OFF. The cycle repeats until a STOP button is pressed.

I manage to create a circuit which can only run for 1 cycle, how do I make it run in continuous cycle until a STOP button is pressed? pls help
thanks

my Ladder Diagram circuit is as follow :

START ----------------------- OUTPUT1[Latch]

OUTPUT1 ------------------- T1 ( timer1 5 second)

T1 ---------------------------- OUTPUT1(Clear)
|------------- OUTPUT2[Latch]

OUT2 ------------------------ T2 ( timer2 10 second)

T2 ---------------------------- OUT2[Clear]
