Alle registerwaarden tonen nul of NaN. Wat gaat er mis?

Dit komt vrijwel altijd door een verschil in slave-adres. De DRT428M2 wordt geleverd met een fabrieksingesteld adres dat mogelijk afwijkt van wat in het portaal is ingevuld. Controleer het adres via het frontpaneel-menu en zorg dat het overeenkomt met het unit-ID in de ModbusCloud-template. Controleer ook of baudrate en pariteit aan beide kanten gelijk zijn.

Energietellers staan op een vaste waarde en worden niet bijgewerkt.

De energieregisters van de DRT428M2 (adressen 256 en hoger) zijn float32-waarden verdeeld over twee aaneengesloten holding-registers. Als de gateway slechts één registerwoord leest in plaats van twee, lijkt de waarde bevroren of is hij onjuist. Controleer of de template float32 (twee registers) gebruikt met functiecode 3 en dat er geen byte-swap-instelling actief is.

Reactief vermogen en reactieve energiewaarden kloppen niet of zijn omgekeerd.

De DRT428M2 registreert afname en teruglevering van reactieve energie afzonderlijk. Als de bedrading verkeerd om is aangesloten (voeding van onderen in plaats van van boven), worden afname en teruglevering omgewisseld. Controleer de aansluitrichting: de voeding moet van bovenaf de meter ingaan. Controleer ook of de totaalberekeningsmode op de meter correct is ingesteld voor jouw situatie.

De RS485-bus werkt met één meter maar valt uit bij meerdere meters.

Elk apparaat op de RS485-bus moet een uniek slave-adres hebben. Dubbele adressen veroorzaken buscollisies en sporadische time-outs voor alle aangesloten apparaten. Controleer ook of de afsluitweerstanden alleen aan de twee uiterste punten van de bus zitten, niet tussenin. Verlaag de pollfrequentie bij lange kabels of meer dan vier meters op één segment.

SKU: fbe22c9b-6720-4015-864e-a5269f4eb899

De BGE-TECH DRT428M2 is een driefasige DIN-rail energiemeter voor submetering in commerciële, industriële en gebouwbeheer-toepassingen. Via Modbus RTU over RS485 leest deze template per fase de spanning, stroom, actief vermogen, reactief vermogen, schijnbaar vermogen en vermogensfactor. Daarnaast legt hij bidirectionele energietotalen vast: afname en teruglevering van actieve en reactieve energie per fase, plus vier onafhankelijke tariefregisters (T1 tot T4) voor tijdzone-analyse. Door de DRT428M2 op de ModbusCloud Gateway aan te sluiten, hebben installateurs en facilitair beheerders doorlopend inzicht in belastingbalans, netto energieafname en teruglevering, en verbruik per tariefperiode.
