Pump Start and Stop?

[KRAZE4LV]

While making the I/O list, I have identified theDigital Ouput,  Port0/line1 as start for the pump and Digital Output, Port0/line1 for stop i.e is two port, lines, of the pump...but while making the software, VI, I am using the verticle toggle switch to consider the start of pump as up and stop as down of the toggle switch which works at one DO port line.

How can I give two signal start and stop to the pump?

Should I use two buttons? Which ones?

I am confused. Please let me know.

What do the two DO lines do?  Ultimately there will be one device (contactor, relay, thyristor, ...) which has two states (like a single boolean) to turn the pump on and off.  How do the two digital lines connect to that control device?  Are they inputs to some kind of electronic pump controller or are they simulating the standard industrial Start and Stop buttons via relays? Something else?

You can use the single switch on the front panel and the boolean Not function to create the two lines for your DO.
