MP277 back-up

Kristoffel Posts: 31 Rating: (0)	For my machine, I use the following configuration for HMI and integrated MMC card and USB stick. 6AV6643-0CD01-1AX1 6AV6671-1CB00-0AX2 6ES7648-0DC50-0AA0 Everything works fine when I do me logging on the MMC card, without the USB stick. Once the USB stick is inserted, at start-up I get the message that it is no longer possible to log on my MMC card. There seems to be a compatibility problem between MMC card and USB stick. Anyone any ideas why and a solution. Continuous logging occurs on the MMC card, when a batch is finished I archive all data onto USB stick.

Kristoffel Posts: 31 Rating: (0)	No, I haven't contacted them...I thought it would be a configuration problem, and that it was not allowed to combine a MMC card with a USB stick. It is a USB stick of 8Gbyte of Siemens, that is not the problem? Because I can only find a FAQ which says that MP277 is proven to work with 2Gbyte sticks of Siemens...
