Shaked Posted July 11, 2017 Report Share Posted July 11, 2017 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! Quote Link to comment Share on other sites More sharing options...
MVP 2021 Ausman Posted July 11, 2017 MVP 2021 Report Share Posted July 11, 2017 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. cheers, Aus Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted July 14, 2017 MVP 2021 Report Share Posted July 14, 2017 You can backup the program to the SD card without writing to flash memory. It's the restore from the SD that writes to the onboard flash. As Ausman said, what is your issue with the onboard flash memory? Quote Link to comment Share on other sites More sharing options...
