Source participation group
Group 6
Group 7
Group 8
Group 9
The participation group number for source 1...source 9 is available in the monitored
output SRC1_PTC_GRP...SRC8_PTC_GRP.
Any source can be nominated for participation in voltage and frequency matching
from the command parameter Source1 selected...Source8 selected. This selection is
confirmed from the command parameter Confirm source Sel. The selected
participation group information is available in monitored data SELECTED_GRP.
ASCGAPC allows multiple sources to participate in the voltage and
frequency matching simultaneously, but all the sources nominated for
matching should belong to either participation Group 2 or
participation Group 3.
One of the participating sources (set with Tuning source) is used for the fine tuning of
voltage and frequency. This information is sent to the corresponding source via the
respective output signal ASC_SRC1_DAT...ASC_SRC8_DAT.
