- No other client may be connected to the PLC during hardware downloads or when resetting the PLC.
- It is possible for all passwords to be passed directly in the command line in clear text as arguments, but this is not secure.
If you just use the flag without a value (--password or --masterPassword), a secure prompt will appear so that you can enter the password securely. - Provide the master password (--masterPassword) for the initial download to a PLC with FW V2.9 or above or when changing certificates (if the password is defined). For details, see certificate handling.
- If you change an IP address change and a downloaded certificate in the same configuration, reset the PLC first or the download will be incomplete and will therefore fail.
- If you change an IP address in the configuration during an initial download, there will be a reconnect step to conclude the download.
- If there is an IP address change in the configuration during an initial download, there will be a reconnect step to conclude the download. This will involve inserting the authentication data for the PLC with parameters --certificate and --password. If there is a mistake, the download will be only partially successful and will have to be repeated with the correct settings and the new IP address.
