Welcome to the site. We are certainly glad to have you.
I am sorry to tell you, but there is no free software to program Mitsubishi PLCs (that I know about, anyway).
You will need to contact your Mitsubishi supplier. The software you need is GX Developer. You will also need a programming cable. Your supplier should be able to get you prices and part numbers.
