Outline of Function

The PROFINET IO Controller Unit stores the following setup data in the internal non-volatile memory (Flash
ROM).
• PROFINETIO Connection Parameters set;
• Allocated IO Device Parameter sets.
All these parameter sets can be backed up to and restored from a Memory Card mounted to the CPU Unit. If
the parameter data of a good functioning PROFINET IO Controller Unit has been saved on a Memory Card, this
saved data can be used to perform a quick configuration, when replacing the PROFINET IO controller Unit,
without the direct use of the Configuration software. The data can be backed up to a Memory Card only. It
cannot be backed up to a EM file.
The backup process does not only involve the backup of the PROFINET IO Controller parameter data, but also
the parameter data of any other Special CPU Bus Unit on the same PLC, as well as the PLC program,
parameter area data, and I/O memory data. This function can be executed in any operating mode.
When performing a backup from the PROFINET IO Controller Unit to the Memory Card, the parameter sets are
stored in the file BACKUPnn.PRM, where nn is the Unit number in 2-digit hexadecimal.
