I've been playing DF after being away from it for a year, and am having trouble with pressure plates.
I have a floodgate attached to a plate w/ settings 0-min, 6-max.  The floodgate is holding back water water that fills a hole w/ the pressure plate.  Idea being, water level gets up to 7, plate turns "off" since 7 is above its trigger range, and the floodgate closes until the water level dips to 0-6.  I open the gate w/ a level, hole fills up, but the plate doesn't trigger once the water level reaches 7 and close the floodgate.

Anyone know what I'm doing wrong?  I seem to remember doing this way back...

It might be sending the trigger too quickly. Floodgates have a bit of a lag time to them. You may also need to use levers to initialize the system, I had a cistern where I had to do that but afterwards everything worked okay.

Pressure plates have a 100 tick lag, and floodgates have a 100 tick lag. So it will be 200 ticks between the pressure plate reaching 7 and the floodgate being triggered.

Pressure plates only have a 100 tick lag when the weight is removed - stepping on a pressure plate triggers it instantly.

Am I doing it correctly?  When you create the pad, the range of water you select is when it is open, yes?  So, if i want to have it open between water levels 1-6, then close on 7, i'd set range from 0min-6max?
