Secure FTP

  1. Import a certificate to the PLC for FTP or create a self-signed certificate.

    Note

    Ensure the PLC clock is set to the current time and date when using certificates on the PLC. Otherwise the certificate cannot be used to secure a protocol (see also AC500_Battery: AC500 Battery SNTP Client Configuration).

  2. Add an FTP server to either ETH1 or ETH2

  3. Set the parameter Security Mode to either BOTH or FTPS only.

    ⇒

    You can use any FTP client that supports FTPS explicit mode (FTPES).

Note

In case you are using a self-signed certificate, the FTP client will show some warnings or notice that it does not know the certificate and wants you to check it.
