Group Configuration flags
The Application objects are assigned to groups with the Group-Flags. The Group-Flags for Station interrogation and Count transfer are defined as follows:
- Station interrogation: All Application objects, which are assigned to the group 1 to 16, belog automatically to the global group: IEC870_GRP_INROGEN;
- Count transfer: All Application objects, which are assigned to the group 1 to 4, belog automatically to the global group: IEC870_GRP_REQCOGEN;
You can prevent the automatical assignment of the application objects to the global group if you mask the according bits during the configuration
Examples:
IEC870_GRP_INRO3 AND NOT IEC870_GRP_INROGEN
or
IEC870_GRP_REQCO1 AND NOT IEC870_GRP_REQCOGEN
