What i understood from this program
PB_start_stop is a momentry push button
In first rung when we push start/stop there will be a rising edge of signal because of DIFU. After first scan motor starts( As we are using Keep instruction so we don't need to hold the button). Motor output coil has logic 1 means it has closed circuit and it is running.
my question is why we have used stop motor (200.01) in second rung?
third Rung flies off my head. Please explain. thanks
