Buffer for system power supply!
The system power supply must be buffered to bridge power outages. As the
power demand depends on the respective node configuration, buffering is not
implemented internally.
To achieve power outages of 1 ms to 10 ms according to IEC61131-2, determine
the buffering appropriate for your node configuration and structure it as an
external circuit.
