Recommendation
With the WAGO ProServe® Software smartDESIGNER, the assembly of a
fieldbus node can be configured. The configuration can be tested via the
integrated accuracy check.
The maximum input current of the 24 V system supply is 500 mA. The exact

Note
If the electrical consumption of the power supply point for the 24 V-system
supply exceeds 500 mA, then the cause may be an improperly aligned node
or a defect.
During the test, all outputs, in particular those of the relay modules, must be
active.
