Siemens SCALANCE Switch Backup

SDA backs up the configuration of Siemens SCALANCE switches, alongside your PLCs, in the same backup schedule and version history.

Supported File Types​

  • Config
  • ConfigPack

Transfer Protocols​

SCALANCE switch backups can be transferred over TFTP or SFTP.

tip

If the network connection to the switch is unstable, use SFTP as a fallback. SFTP is based on TCP, which retransmits lost packets, while TFTP is based on UDP. SFTP is only supported by newer SCALANCE firmware versions.

Network Requirements​

info

During the backup, the SDA Gateway acts as a port-forwarding gateway on port 69. Make sure port 69 is open between the SDA Gateway and the switch.
