Erläuterung der Fehlercodes

01	Unbekannter Funktionscode.
02	Die in der Anfrage angegebene Registeradresse ist nicht verfügbar.
03	Der im Abfragedatenfeld enthaltene Wert ist ein ungültiger Wert.
04	Ein nicht behebbarer Fehler trat auf, während der Slave versuchte, die angeforderte Aktion auszuführen.
05	Der Slave hat die Anfrage angenommen und bearbeitet sie, aber es dauert lange. Diese Antwort verhindert, dass der Host einen Zeitüberschreitungsfehler erzeugt.
06	Der Slave ist mit der Verarbeitung eines Befehls beschäftigt. Der Master muss die Nachricht später wiederholen, wenn der Slave freigegeben wird.
07	Der Slave kann die in der Anforderung angegebene Programmfunktion nicht ausführen. Dieser Code wird bei einer erfolglosen Programmanforderung mit Funktionen mit den Nummern 13 oder 14 zurückgegeben. Der Master muss Diagnoseinformationen oder Fehlerinformationen vom Slave anfordern.
08	Der Slave hat beim Lesen des Erweiterungsspeichers einen Paritätsfehler festgestellt. Der Master kann die Anforderung wiederholen, aber normalerweise sind in solchen Fällen Reparaturen erforderlich.
