M520AM memory backup via RS232

[swingline]

A friend recently acquired a CNC with a Mitsubishi meldas 520AM PLC and want to backup the memory in case of a battery failure.

Is there a step by step procedure to backup and restore the memory via the RS232 port?

All the manuals should be on the MEAU site.

I went thrue all the manuals and I could not find anything on how to do a backup. I was hoping there would be someone who as done a backup and would guide me thrue it.

What data does he wish to backup? Does he already have the RS232 communicating with a PC now?
