Backup Program to SD instead of FLASH

Recommended Posts

Dear All,

I am using a V570 PLC. I would like to  back my program up to non-volatile memory, but avoid the onboard flash memory. I was hoping to do this with an SD card, but it seems like when the program is uploaded from the SD card (via Information Mode), it automatically writes it to the flash memory. 

Does anyone know of a way around this?

Thanks in advance!

Hi Shaked,

Uhhhmmmm, why?  If you have your program on the SD why are you worried?  If it is that you are wanting to back up your variables that might change during operation, then you could put all of them into data tables that you could periodically store onto the SD.
