I am trying to use FTP functions on CX8190 (Beckhoff). I want to use FB_FTP_HostResolve, then FB_FTP_Open and after FB_FTP_FileUploadEx to upload a CSV file on FTP Server.

I used that way already on other PLCs of Beckhoff and also on this one before but now does not work anymore and I have no idea what can be the problem.

FB_FTP_HostResolve is the first function block that is triggered on this sequence and I get :

Error ID 32769 - "Internal Error TwinCAT FTP Client."

Trial License for the system is there, CAB file of TF6300 is saved and installed on device, FTP server is active. But error is there.

Is there anybody that knows what can be a problem? I already tried with installing new Image etc. I can not find the problem, neither does Beckhoff.

Probably late but I faced the same issue today so if it can help someone : You have to allow Fillezilla to communicate through windows firewall FileZilla communicate through windows firewall

This could be a workaround: Call another windows ftp program from inside the plc with NT_StartProcess and by passing the correct command line arguments with the path to your .csv file.

NT_StartProcess on Beckhoff website.
