for example, see this video at 4:31 time have showed the diagram:

The relays in that video have NO and NC. I understand if I have a NO and NC on each relay I have the 24V on Relay 1 NO and GND on Relay 2 NC. then I do GND on Relay 1 NC and 24V on Relay 2 NO. Then with interlock, both relays flip the voltage flips and the motor moves in the other direction. The F24 only has NO and COM for each relay. Do you have an example driving a DC motor in both directions with only 2 relays from the F24?
