Dear all,
I am doing a PLC program for 2 duty and 1 standby pump rotation control by using Mitsubishi Q series PLC.
The control sequence of the pump as:
First start: Pump 1 and pump 2 duty. Pump 3 Standby
Second start: Pump 2 and pump 3 duty. Pump 1 Standby
Third start: Pump 3 and pump 1 duty. Pump 2 Standby.
Then back to First start again.
I have designed the similar program in Zelio SR2 Smart relay with the helps of "counter" and "counter comparator" instructions. But I am wondering how to do the similar programming in Mitsubishi Q Series PLC.
Pls advice. Thanks.
