The existing IT objects can individually be configured to belong to any IT object group 1…4. When an IT master command is performed, it can be directed only to a specific IT object group or to all IT object groups. There are two commands related to counter groups.
- Freeze counters, C_CI_NA_1 (FRZ) - Freezes/latches momentary counter values simultaneously and saves them as internal frozen counter values
- Read frozen counters, C_RD_NA_1 (RQT) - Requests the internally saved frozen counter values
