Group Konfigurationsflags
Mit den Group-Flags werden Applikationsobjekte bestimmten Gruppen zugeordnet. Die Group-Flags für Stationsabfrage und Zählwertübermittlung sind auf folgende Weise definiert worden:
- Stationsabfrage: Alle Applikationsobjekte, die der Gruppe 1 bis 16 zugeordnet wurden, gehören automatisch auch zur globalen Gruppe: IEC870_GRP_INROGEN;
- Zählwertübertragung: Alle Applikationsobjekte, die der Gruppe 1 bis 4 zugeordnet wurden, gehören automatisch auch zur globalen Gruppe: IEC870_GRP_REQCOGEN;
Sie können aber die automatische Zugehörigkeit der Applikationsobjekte zur globalen Gruppe verhindern in dem Sie die entsprechenden Bits während der Konfiguration ausmaskieren.
Beispiele:
IEC870_GRP_INRO3 AND NOT IEC870_GRP_INROGEN
oder
IEC870_GRP_REQCO1 AND NOT IEC870_GRP_REQCOGEN
