How to run stations parallel and sequential

[zenonmb]

Colleagues,

I have this setup:
Pump1
Station 1
Station 2
Station 3

Pump2
Station 4
Station 5

I want to be able to run both pumps at the same time, but stations sequential.

For example. Both pumps stars at 6 am, and running time 1 hour per station.
So at 6 am, pump1 starts and open station 1, pump2, at same time opens station 4. At 7, both pumps runing,station 1 closes, and 2 open. Similarly , station 4 turns off and 5 turns on.
At 8 o clock,station 2 off and 3 on, and station 5 turns off. Pump2 turn off as well.
Finally at 9, station 3 and pump1 both turn off.

How can i program this?
