plasma control panel
Next in line a 6x2 meter to be built plasma and acetylene machine, and a retrofit of an industrial Hypertherm 12x3 meters 400Amp monster that must have at least a ton of cables ( guesstimate). Talk about versatility!
0v means they are both connected to the 0v rail of the COMMON 24V POWER SUPPLY.

Yes, that is correct.

Your -V = 0V on the COMMON 24V POWER SUPPLY
Your +V = 24V on the COMMON 24V POWER SUPPLY
one leg of the resistor connects to either TB5-6 or to the socket your cable to the plasma unit plugs into.

For the 220 ohm resistor, I need to connect 1 leg of the resistor to TB5-6 on 7i76e and also from the end of this leg, I will solder a cable and connect this cable to 0v on the 24v power supply. Is it correct? Thanks.
the other leg could connect to either TB3-24 or TB1-8 as 0v is connected to both of those or -V on your power supply.
