How to access data files written to SD card on ctrlX Core X3?

[Vaaclav]

Hi, I implemented data logging to .csv files, which are written to SD card mounted in ctrlX Core X3. Every day one logfile, few hundreds of kB in size. Everything seems to be running fine. But how can I see and download these data files? I can't access the SD card partition from ctrlX PLC Engineering software, neither through WebDAV. The data path is default:  /media/mmcblk1p1

Thank you

Hi Vaaclav,

unfortunately this is not yet possible, the function is scheduled for next year.
Maybe, as a workaround, you could copy the file from microSD to active configuration with the some app, eg. NodeRED or PLC?
Then you would be able to download it.

OK, but then I can save the files directly to active configuration (perhaps the SD card couId be used to extend disk space).

Initially, I wanted to avoid frequent file writing to active configuration (every minute, 24/7), to save system flash memory lifetime. I expected the system flash memory chips still do have limited R/W cycles. Or is this not a problem anymore and I can write to active configuration memory space without negative impact on service life?

You still have the negative impact. Thats why I suggested copying just once a day or so.
