How to access FTP from RobotStudio

Hello all

try to connect to my FTP server on the same machine as robotstudio with no sucsess.


Under Motion Configuration i have:
- 614-1 FTP-Client
- 615-1 NFS Client
- 616-1 PC Interface

under Configuration-Communication I have the correct IP address ( Tried and localhost - nothing.

When I connect from a "real" controller (running robot) it works perfect - so my FTP Server is OK.

Any ideas?


  • I've never had any success with the FTP-Client option in RobotStudio, connecting with an application like FileZilla however seems to work with no issues. 
  • I have problems with FileZilla.

    -vsFTP (Debian)
    - own Java FTP-Server (Windows/Debian)

    not working:
    - FileZilla (Controller doesn't seem to send the password)
    - own C++ FTP-Server (instead RETR command controller send LIST command)

    I tried several FTP-Clients to access a file from my C++ FTP-Server (integrated into my software) and they all work. So username, password, IP etc must be correct.

    Maybe if you could share the settings of your FileZilla-Server could lead me to the solution?

  • When I login via FileZilla I don't use a username/password, leaving it blank works just fine. I am using RW 5.15 though
  • OK, I'll try. I have same RW

    Here what I get:

  • hmm - are you using FileZilla as a client to access the controller or the Server to access FROM the controller to the FileZilla FTP Server?

  • Access the controller
  • ok, I try the other way. Thanks anyways!
