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

4

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

6

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.

9

Then these files can be call in the program cycle?

How can we create USER partition? any documentation?

10

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

Ok let me have a look thanks

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
