How can delete the log files directly from the SD card?

At this moment I'm struggling with the delete button. How can I delete the log files directly from the SD card?

Downloading works fine from the command line:

wget "http://192.168.11.11/UserFiles?Name=log-20220704-113048-312.csv&Action=DOWNLOAD" --user Administrator --password Secr3t!

This plc does a lot of logging, and manually downloading and deleting is no option, it results in a lot of hours work a day, also removing the SD card using a pc every day in order to move the files to a local directory: the plc has to be turned off for a few minutes and this is not acceptable to the production departments.

I'm working on an automated process in order to download all logs and keeping the SD card clean, with wget or curl, but I can't get this delete button working. Is there someone who already has managed to do this?

Thanks in advance.

Split from Direct access to data log using S7-1500 web server.

Is the log file closed when delete is attempted?

If not, set up a PLC routine that forces logging to a different file before attempting to download and delete.

I think a newer PLC firmware might be necessary.  Some version of s7-1500 firmware update readme I believe mentions improving log file delete options.

 Yes, the files are generated in one action, when the memory is full. These are user files written with the FileWriteC function in TIA. Deleting from the web interface works just fine. Only via Curl or Wget it doesn't.

At this moment I can't upgrade the cpu from version 2.8.2 to 2.9.4 because the download failed, and now this download is blocked in my account. My colleague also tried to download it, but he has no permission to download yet. So this part will have to wait until he can perform this download.

This is the link to the firmware.

Hi,

I would suggest a cURL command (https://www.curl.se).

As I read from your post the file you want to delete is in UserFiles. (Notice there is a difference to other folders)

After login via wget (if necessary)

wget --no-check-certificate --post-data="Login=[username]&Password=[password]" --save-cookies="cookies.txt" --keep-session-cookies "https://[ip]/FormLogin"

cURL command:

curl -b cookies.txt "https://[ip]/UserFiles?Action=DELETE&Name=[filename]" -X "POST" -H "Origin: https://[ip]" -H "Referer: https://[ip]/Portal/Portal.mwsl?PriNav=UserFiles"

 After that the file should be deleted from SD Card.
