Import a certificate to the PLC for FTP or create a self-signed certificate.
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” and ⮫ “(S)NTP client configuration”).
-
Add an FTP server to either ETH1 or ETH2
-
Set the parameter “Security Mode” to either “BOTH” or “FTPS only”.
You can use any FTP client that supports FTPS explicit mode (FTPES).
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.
