hi
i am new to plc i was asked to write a program for two pumps(1 stand by and other running)which will run in normal way like when triggered. But when the operator press the cyclic duty button without interrupting the process next available pump should come in sequence.
i was able to find the next available pump but but cant make it in standby queue and
how to make the standby pump run when the running pump stop.
thanks in advance
