HI, being a novice and currently having brain "****" My problem is: I need to trigger a long ( 3 min.) timer when I start a shut down sequence. The limitations are: the PLC I'm using is only capable of 0.01 time base and 32,xxx. So I'm using a delay on break timer with a counter to reach the required real time, but without the one shot falling command, I'm not seeing away to trigger the timer. I thought of either NAND &/or NOR logic but having a problem implementing it.
