You Can easily program the PLC that when mtr drops out on overload other one does same.
How will the PLC know that the motor drops out on overload?

Most IEC-style motor starters have a built OL contact to use as feedback for alarms or to a PLC. Most NEMA-style starters can have one added for the same purpose. NOTE: I am NOT referring to the NC OL contacts usually factory wired in series with the coil.
Wire the OL contact from each starter as PLC inputs and change the program to drop out the coils.
