Weidmüller EM220-RTU
Dreiphasiger Energiezähler, der Leistung, Energie, Bedarf und Oberschwingungen misst, mit Digitalein- und -ausgängen.
Der Weidmüller EM220-RTU ist ein dreiphasiger Energiezähler, der Spannung, Strom, Leistung und Energie in Verteilungen und Schaltschränken misst. Diese Modbus-RTU-Vorlage liest alle Messwerte, Bedarfswerte, Oberschwingungen und Eingänge und lässt Sie Wandlerverhältnis, Bedarf, Ausgänge und Alarmschwellen aus ModbusCloud einstellen.

Anwendungsfälle
- Zeigen Sie Leistung, Energie und Leistungsfaktor je Phase einer Verteilung auf einem Dashboard in ModbusCloud.
- Lassen Sie sich alarmieren, wenn der Strom einer Phase oder der Gesamtbedarf eine von Ihnen gewählte Schwelle überschreitet.
- Speichern Sie Bezug und Einspeisung je Phase ein Jahr lang, um Mieter, Maschinen oder Monate zu vergleichen.
- Beobachten Sie THD und Oberschwingungen der Spannung, um einen störenden Verbraucher zu finden.
- Zählen Sie Impulse eines Wasser- oder Gaszählers an den Digitaleingängen und protokollieren Sie sie neben der elektrischen Energie.
- Schalten Sie einen Digitalausgang aus ModbusCloud oder einer Automatisierung, etwa für einen Lastabwurf.
Installation
Verbinden Sie RS485 A und B des Zählers mit dem RS485-Anschluss des ModbusCloud Gateway, mit einem 120-Ohm-Abschluss am Ende des Busses.
Stellen Sie am Zähler die Modbus-Adresse ein (Standard 1) und prüfen Sie 9600 Baud, keine Parität und 1 Stoppbit, oder die Werte des übrigen Busses.
Stellen Sie Netzform sowie Strom- und Spannungswandlerverhältnis am Zähler oder später aus ModbusCloud ein, damit Leistung und Energie Primärwerte sind.
Fügen Sie in ModbusCloud ein Modbus-Gerät am Gateway hinzu, wählen Sie die Vorlage Weidmüller EM220-RTU und geben Sie die Adresse ein.
Prüfen Sie, ob Spannung, Strom und Frequenz mit plausiblen Werten ankommen und ob die Leistung bei einem Verbraucher positiv ist.
Zu beachten
Der Zähler antwortet nicht am RS485-Bus. Was prüfe ich?
Prüfen Sie, ob Adresse, Baudrate, Parität und Stoppbits mit den Einstellungen in ModbusCloud übereinstimmen. Tauschen Sie A und B, wenn nichts antwortet, und sorgen Sie für einen Abschlusswiderstand an beiden Enden des Busses. Mit gerader oder ungerader Parität nutzt der Zähler immer 1 Stoppbit.
Warum ist die Leistung auf einer Phase negativ?
Vermutlich ist ein Stromwandler verkehrt herum montiert. Drehen Sie ihn, oder setzen Sie Current Direction Correction für diese Phase. Das Vorzeichen des Leistungsfaktors folgt der Stromrichtung: positiv vorwärts, negativ rückwärts.
Warum erhalte ich einen Fehler beim Schreiben von Wandlerverhältnis oder Netzform?
Diese Schlüsselparameter sind geschützt. Schreiben Sie zuerst das Zählerpasswort (Standard 1000) in Key Parameter Programming Authorization und danach den neuen Wert. Der Zähler nimmt Schreibbefehle nur mit Funktionscode 16 an; die Vorlage nutzt diesen bereits.
Kann ich mehrere EM220-RTU an einem Bus betreiben?
Ja. Geben Sie jedem Zähler eine eigene Modbus-Adresse von 1 bis 247 und legen Sie jeden in ModbusCloud als eigenes Modbus-Gerät mit derselben Vorlage an. An eine RS485-Linie passen bis zu 32 Geräte.
Worauf achte ich beim Schreiben von Einstellungen?
Ein falsches Wandlerverhältnis verändert alle Leistungs- und Energiewerte, und Reset Historical Data löscht Energie, Bedarfswerte oder das Protokoll endgültig. Lesen Sie zuerst den aktuellen Wert, schreiben Sie eine Einstellung nach der anderen und prüfen Sie das Ergebnis am Zähler.
Selbst sehen, wie es funktioniert?
