I'm totally new to PLC's and I've just purchased an FX3U-14MR Mitsubishi Clone. I believe I need to use GX Works Software to program it but I've been unable to find a version that will install on my PC, I've tried downloading from the official Mitsubishi site but it will not install unless I provide a Product Code and yet I see others are able to program their FX3U's with GX Works. If possible I would appreciate a link to a GX Works version I can download and install without needing a product code.
