Is there any plans or way to turn on SFTP support ( SSH FTP, not FTP + S(FTP with SSL encription) ) in B&R PLCs?
I imagine one roadblock is that SSH isn’t enabled on the PLCs to begin with, but SSH is supported on VxWorks (as of VxWorks 6.5).

I haven’t heard of any plan about that so far.
Just for my interest: since ssh itself would not be needed for todays PLCs because of no command shell available (at least as I understand the common usage of ssh), are you asking because of firewall configuration as SFTP only uses one dedicated port?
Best regards!
I suspect it’s about this: Many FTP clients are no longer maintained by the programmers, but WinSCP, for example, is a very well-maintained SFTP client and is also encrypted.

Yes, it is more of a cyber security issue as many companies IT policies are not allowing FTP connections through firewalls, and FTPS (FTP + TLS/SSL) requires multiple ports. SSH and SFTP have IT advantages over the standard FTP or FTP+SSL.

We recently stumbled upon this as well. Some suppliers (e.g., Sensopart) only support SFTP as encrypted filet transfer.
