WebVisu: Login Required When FileTransferServices Is Enabled

CODESYS
1

Hello everybody,

I have a configuration with a PFC300 and a WP400.

I need to enable user/password management to prevent unauthorized PLC downloads.

At the same time, I have enabled the following setting in the CODESYS configuration:

CmpWebServerHandlerV3

AllowFileTransferServices=1

because I need to download some files from the PLC through a WebVisu client.

When this setting is enabled, the client is prompted for login credentials at startup.

Is it possible to remove this login request while still keeping user management enabled to prevent unauthorized PLC access?

Does anyone have any ideas or suggestions?

Regards,

Hello what is the fw revision you are using ?
I know some firmware had this option not working properly.

Hello,

I am using the latest firmware version (FW31).

The system stops working properly when I add

AllowFileTransferServices=1.

Do you have any idea what could be causing this issue?

Thanks.
