Please help me writting ladder logix for queing a request to start a pump.
I have a pump and three remote operator stations.
Station A: if pressed turns the pump ON and valve to area A opens.
Station B: if pressed turns the pump ON and valve to area B opens.
Station C: if pressed turns the pump ON and valve to area C opens.
After the pump starts it runs to a certain time and stop.
Now if any station is pressed the pump should start immediately. If the pump is being used by another station. The request is placed in a que in a first comes first serve manner.
Please suggest what instruction should I use to que this request and how.
I use RSLogix500 and micrologix 1200 to practice.
Thank you
