Formatting the memory card is possible by using the %SW93 word via the Unity Pro animation table. When the memory card is formatted, the default directory "DataStorage" is created. Before formatting with Unity Pro, the user must download an application by default. Otherwise, the %SW93 system word does not exist. Formatting is only possible when the PLC is in STOP mode. The formatting command and status of the memory card are provided by the %SW93 system word.
