And I also have implemented an FTP client without the cp, using only open communications (though the tdiscon block has another problem: https://support.industry.siemens.com/tf/ww/en/posts/s7-1500-tdiscon-doesn-t-close-the-connection-cleanly/213859/?page=0&pageSize=10) In my block I can use both active (which requires a passive connection establishment) and passive ftp mode (active connection establishment), so I have no problem with tcon, only with FTP_CMD and tdiscon. |

Dig down into the connection parameters, and when you get to the TCON_IP_V4, the parameter "ActiveEstablished" may help. FYI, the structure (layout) of the TCON_IP_V4 datatype varies depending on the version of TCON in use........
