I'm coming from a background of PLC ladderlogic/rockwell products. I am new to blocks. Can you point me in right right direction?
What I would like to do: control tank level
**All hypothetical for educational purposes**
Let's say there is a PID block controlling a valve position (filling a tank) with a setpoint of 75 in full Auto mode. When the tank level hits >90 I want the PID control to be disabled while in Auto operation and the valve goes to 100%
When the tank level <85 I want the PID block to take back control.
What suggestions to accomplish this? I am seeing some compare blocks with >,< type logic for the block nubs.
Lastly: what does nub stand for? I realize it's the connection points from the various blocks to others. Thanks!
