Hi All, I have 2 pieces of manufacturing equipment that are using a MELSEC FX3U – 16M and a MELSEC FX2N – 12MR for their control. Currently do not have a backup of the program uploaded to the PLC and would like to have one, just in case of hardware failure of some description I understand I need to connect a computer to it through the communication port, I have the specific serial to usb cable. I would like to know what software I need and the process of downloading the program from the PLC and if there are any dangers by doing this. Thanks in advance Michael

The company that programmed the equipment has gone bust and unable to contact any of the old employees. Thanks for all the help guys, I may have to get a 3rd party in to just take the backups on the AB PLC's.

Thanks for the help guys
