Have you seen a single complain about damaged PLC from 170K+ viewers?

It shows that the Mitsubishi is bomb proof I admit but as a principle, hashing these two protocols together like this is not a guaranteed practice.  The voltage levels are too diverse.  Not all designers will have such a thorough protection circuit on their hardware.  To evade needing to have an RS232 to RS422 converter I do not believe that this is a valid technique.

The FX-232AW is an RS232 to RS422 converter with extended list of signals, and you can not repeat its schematics alone. You should use standard accessories for this connection, at least like SC-09 cable.

Just buy a cable.  Mitsubishi PLCs use RS422, your PC is RS232.  At a minimum you need a converter.

FX-232AW has 2 25-pin serial ports, not parallel ports.

For goodness sake save yourself time and heartache and buy a lead at only $6.00 it's a no brainer.

This image is found on page 4 of this post. As you can see, you will need electronic conversion between the 25 pin and the 9 pin. This is why your direct connection is not working.

Sigh, as nephets says, buy one for £5

The SC09 has a 25 pin plug and socket.

You pull it apart when you need the 25 pin part

The section on the left side is an adaptor for the newer PLCs. You only need the cable on the right side. It is the correct gender. There is a converter inside the 25 pin hood. A direct (Pin to Pin) connection will NOT work.

SC09 is two pieces and has both 8-pin round and 25-pin PLC plugs, as was visible in this thread.  .
