ICTS-Pusher Delay Holding Timer
I managed to completed the ladder and test for the Pusher Delay Holding Signal today. In fact this part is required since the longer stretch pneumatic pusher need longer time to complete one cycle of out and return. The current cutter signal is too short that sometimes causing the valve to retract even though the cycle is not finished yet.
Here is the logic that I used to simulate

As you can see the TIM0 is ON when IR0 is set to ON by 4 inputs. Once IRO ON it will continuosly ON until IR1 will trigger it OFF. As such the PUSHER VALVE will be ON from IR0 ON until IR1 ON. In this case it will be continuosly ON for about 0.6s as the timer SET VALUE.
