Motor Switching

Hi,

Can someone help me in programming motor switching part?
Below are what I trying to do
1. After pressing the Auto button, motor A start running.
2. Once motor A stop whether is because of alarm or manual stop it, the next time of the auto run, motor B will start running.
3. If motor B stop, then next time of auto run will be motor A again and so on

That's called an "alternator" circuit. You can buy an alternating relay, or if this is a PLC code issue, there are plenty of examples of how to accomplish it, but you would need to indicate what kind of PLC you have.

I am using Allen Bradley PLC 1766-L32AWAA.
Can I have some sample code on how to do that?

If you do a quick search of the forum for "flip flop" you will get a number of results that will guide you in the right direction.
