Configure file transfer connections
Panel View 5000 allows you to configure up to five file transfer connections, which you can establish to transfer files and folders between the SD card or USB drive on the HMI device and an external FTP server. File transfer connections are configured on the settings screen in runtime and each connection has its own ID from 0 to 4.
The following protocols are supported:
- FTP: Not encrypted or secure. Uses Plain text authentication with username and password but can also connect anonymously.
- SFTP: Encrypted, secure, uses SSH key fingerprint. If you want to use the SFTP protocol, you must accept the SSH key fingerprint (see connection verification process). SSH keys are lost after firmware update, you must accept them again in the runtime application. Each connection keeps its own SSH key even if more than one connection is configured to the same SFTP server. Each connection can only use one SSH key fingerprint.
- FTPES: encrypted, secure, uses certificates.
To configure a file transfer connection in Panel View 5000:
- Go to Settings > File Transfer.
- In File transfer connection, in the left pane select a connection you want to configure.
- Select Connection type and select a Port number you want to use.
- In the Server address field, enter the server’s name or IP address.
- In Username, type the username.
- In Password, type the password.
- (Optional) In the Description field, enter the description of the connection.
- (Optional) In the Folder location field, enter a subfolder on the remote FTP server specified in Server address. The Folder location configuration is only needed if you are using a subfolder under the main folder path used by your FTP server.
TIP:
You can enable anonymous connection on the FTP server. The server must be configured to accept anonymous connection, and the anonymous user needs at least read permissions.
To configure an anonymous connection to the FTP server, enter anonymous or ftp as the Username, depending on the internal configuration of the FTP server. Password is ignored for anonymous users.
- Click the Verify button. If the connection is successfully verified, a success icon is displayed next to the Verify button.
If the connection fails to verify, perform the following actions:
- To view the details of the verification error, click the Details button.
- Verify server properties (server address, port number, remote location, credentials, and connection type) and select Verify again.
- If sftp protocol is selected and verification fails (even after server address, port number, username, and password are entered properly). The Details screen shows the SSH Key. Press the “Accept SSH Key” button if you want to use sftp connection. Once the SSH key is accepted, the message "SSH Key Accepted" is shown at the bottom of the Details screen. The File transfer connection configuration screen should now show a success icon.
