I am attempting to run multiple FTP connections to upload multiple files at once to a FTP server. I am using FB_FTP_OpenEx(Active Mode), FB_FTP_FileUpload, and FB_FTP_Close. However, when opening multiple connections,the FTP client returns error code "32769 - Internal Error TwinCAT FTP Client".
Any ideas what I am doing wrong? Is what I am trying to achieve possible?
Thank you.
I have checked for limitations on simultaneous connections imposed by the FTP server.
The FTP function works when only 1 connections is established but fails with multiple connections.
