Buffer for system power supply!
The system power supply must be buffered to bridge power outages. As the power de-
mand depends on the respective node configuration, buffering is not implemented internal-
ly. 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.

Tab. 6-7 Technical data – ETHERNET
No direct access from fieldbus to the process image of the terminals!
Any data that is required from the local bus process image must be explicitly mapped in the
CODESYS program to the data in the fieldbus process image and vice versa! Direct ac-
cess is not possible!
