During the distribution procedure atvise Builder uses the FTP ethernet protocol. The connection will be established using the passive FTP mode. The atvise Builder initiates a connection using a PASV command over port 21 while the netSCADA device replies over a free port >1023. You may use a standard FTP client such as Filezilla https://filezilla-project.org/ to get access to a netSCADA device alternatively. In case you want to a establish a connection over Internet across a router to a local netSCADA device then you have to open or forward the port 21 and the specific netSCADA FTP reply port in order to allow a proper connection from remote. |
