That is about 4 rungs of ladder in Classic ladder. Two timers, one
timer times out and starts the second one. When the second timer times
out it opens a NC contact that feeds the first timer.So timer 1
times out, starting timer 2 which resets timer1 and the loop continues.

These are gener
The classic ladder example sim has always had a timer in it.

I had previously tied my oil pump to the run signal on my VFD, so when
the machine was running, lube pump was running.
The lube pump works with a cam raising an oiler, then letting the
spring/gravity drive the pump to push the oil out.
My understanding is that it's pretty common to oil way too mu
