Mitsubishi FX3U Trasfer memory cassette to plc

4 posts in this topic

FX3U plc, trying to trasfer memory cassette contents to plc (or vice versa) without removing the memory cassette.
1st way is to use GX Developer, copy the program from the cassette, remove the cassette, and copy the program to FX3U Ram(but i don't wanna do this)
2nd way is to have a cassette with transfer loader like FX3U-FLROM-64L and use the onboard buttons to get the job done. (you don't have to remove the cassette).
3rd way is to have a FX3U-7DM screen attached to the plc and use the screen menu to transfer your program.

Question:  Anybody knows an alternative way? (without removing the cassette and not owning a FX3U-FLROM-64L or a FX3U-7DM). Maybe using a GX works 2 or GX Developer or any other loader maybe). Regards

As far as I know, those are the only three options.

Software can't access the memory card.  Only when it's in a PLC. 

If you go online with a PLC that powered up with a memory card installed, you are reading the program in the memory card.

If you go online with a PLC without a memory card, you are reading the internal memory of the controller.

The cards should never be installed or removed under power in the FX families.
