<!-- END GENERATED -->

Der ABB-B2x-Energiezähler kommuniziert über **Modbus RTU** auf dem RS485-Bus
des Hubs. Dreiphasige Messung (Spannungen, Ströme und Leistungen je Phase).

## 1. Benötigte Hardware

- ABB-B2x-Zähler
- USB↔RS485-Adapter auf Hub-Seite
- Buskabel, 2 Adern (A/B) + Masse

## 2. RS485-Anschluss

A↔A, B↔B, gemeinsame Masse, **120 Ω** am Busende.

## 3. Modbus-Adressierung

Eindeutige Slave-Adresse am Bus (`1`–`254`, Standard `1`).

## 4. Hinzufügen in PowerSync

Hinzufügen per **automatischer Erkennung** oder **manuell** (Eingabe der
Slave-Adresse). Siehe [Gerät hinzufügen](../../installation/application.md).
