Some of ei3‘s Remote Service users may need to reach an FTP server on a machine device during a remote service session.

Any remotely accessible device that runs an FTP server must be configured to use passive mode FTP, with standard TCP ports 3001-3004 used for passive FTP data transfer, in order for a Remote Service user to successfully access it during a remote service session.

The selected TCP ports must also be allowed in the configurations of the Amphions used to create the remote connection to the device. For more information about how to do this see this article.

These requirements must also be met for the case when it is desired to access the FTP server of a machine device from some other device located on the customer’s factory site LAN. For more information about how to set up this case in ei3 for the proper Amphion configurations see this article.
