Secure File Transfer Protocol (SFTP) on the FANUC R-50iA controller is a practical way to protect automation assets, engineering time, and production stability. In this video we walk through why SFTP matters, how it compares to traditional FTP, and how the controller supports both server and client roles so we can handle backups, restores, and day to day file work with confidence. We position secure connectivity as a standard part of maintenance and commissioning rather than an add on.
We start by setting context. FTP can move files, but it exposes passwords, programs, and directory listings in cleartext. That does not align with modern cybersecurity policies. We then focus on what SFTP adds through SSH encryption for credentials, commands, and data, plus simpler firewall handling with a single TCP port 22. From there we compare SFTP Server (option S612) and SFTP Client (option S613) so we can decide when to accept inbound secure sessions and when to initiate outbound connections. We also cover password and public key authentication at a high level and point out the software version requirement for public key on the server.
To make it actionable we will go over the tag based model used for secure sessions. Server tags S1 through S8 manage concurrent inbound connections. Client tags C1 through C8 map to remote servers or distinct directories to support layered backup strategies. We share simple guidance to align tag usage with backup frequency, change tracking, and redundancy without extra admin work. This sets us up for the follow on configuration session.
Requirements (Prerequisites / Environment):
- R-50iA controller with base software initialized
- Option S612 (SFTP Server) and/or option S613 (SFTP Client) licensed
- Network access to TCP port 22 and updated firewall rules
- Controller user accounts or LDAPS Client (option S609) for password authentication
- Software version V10.10P/24 or later for public key on the server
- Reachable remote SFTP server and storage for backups
What We Will Learn:
- Key differences between FTP and SFTP in robotics
- How encryption protects credentials, programs, and configuration data
- When to use SFTP Server vs SFTP Client in operations
- Password vs public key selection and where each fits
- Tag strategy with S1..S8 and C1..C8 for scaling connections
- How to get ready for the configuration deep dive
By the end we will share a clear view of why secure file transfer is foundational for controller lifecycle management and how SFTP strengthens both compliance posture and daily reliability. Join us to raise the bar on robot file handling with encrypted methods that fit existing maintenance routines.
