Modbus TCP muss vom Installateur oder vom Ferroamp-Support für den EnergyHub freigeschaltet werden.
|
||||
Die Schnittstelle ist ausschließlich über die Ethernet-Schnittstelle des EnergyHub erreichbar.
|
||||
Die Netzwerte werden über die externen Stromwandler (CTs) am Netzanschlusspunkt gemessen.

Modbus TCP has to be enabled for the EnergyHub by the installer or Ferroamp support.
|
||||
The interface is only reachable via the EnergyHub's Ethernet interface.
|
||||
Grid values are measured by the external current transformers (CTs) at the grid connection point.
