Hi, Any idea what is the reason for the files inside the CF card will be deleted byitself

I found inside the Logger Internal error - hardware test- Voltage monitoring

Hi, No transfer has been done ?

No transfer has been done I noticed this issue occurs when we have an alarm on SafeCPU Then when i restart my PLC i lost some files

We created these files It is on the partition It is on the C drive partition Can we see something inside the logger? I found inside the Logger Internal error - hardware test- Voltage monitoring

Yes you could maybe see something in the logger. I would not recommend to created files on the C drive partition, you should use the USER partition.

Then these files can be call in the program cycle? How can we create USER partition? any documentation?

You need to declare the size of the partition in the hardware configuration of the PLC.

Then you can create a File device with path is “USER_PATH“ it will directly point to USER partition. Then you can use the file device in any lib like FileIO or others

You can check the error number in the help to get more info, else if there is no more info you can contact your local B&R support to get more infos!

Is those files are on the USER partition? It’s files you create / read by the PLC ?
