Problems with unreadable robot system floppy disks? Lost program disks? Boot disks nobody can find?

We developed a product to solve floppy disk problems; Disk Drive Replacement (DDR).

The DDR replaces all old floppy disk units in ABB robot systems (S2, S3, S4, S4C and S4C+ with DSQC540 computer)


The DDR comes at a price of 420EUR (excl. VAT).

Article numbers:
S2: 900055
S3: 900052
S4: 900053
S4C+: 900063


DDR overview

  • Program, backups, parameters and boot disks are stored on a single SD card and operate according to the same principle as a hard drive for the robot system. It is a major benefit having a boot pack that is always available.
  • Backup and restore of the entire SD card to a PC or network. This was never possible before in S2 or S3 systems with old drives
  • File management and editing of programs in S4, S4C and S4C+ (with DSQC540 computer) can be executed as usual in a PC using “DDR PC Software 2”
  • Possibility of using the old floppy disk unit in parallel with DDR in S3, thanks to a special switch cable. This makes it easy when transferring programs and parameters
  • Environmental endurance and safe storage of data in a CE-marked product
  • Installation in just a few minutes
  • Very low purchase price
