Hi JoraMartio, You need Mitsubishi Melsec GX-Developer software that is integrated as a part of GX-Works2 and a SC09 cable to connect to your computer. If your computer has no serial COM port you also need an USB to Serial converter to connect. Remember that an upload from your CPU only gives you a raw ladder without labels. Example: In your ladderdiagram after upload you will see X2, Y30, D100 however it doesn't say X2, stop button, Y30 Motor left, D100 temperature etc. So you need to figour it out which labels and attach it yourself.
