Description
SAV No SmpSynch 18 52 00000000
This is a data cell with 8 binary flags. It indicates the healthiness of the Sampled Values being received from each of the
configured Merging Units.
0: Sampled Values received are synchronised and any loss of samples is within acceptable limits.
1: Sampled Values received are not synchronised (Setting :Synchro Alarm) or the Sampled Value delay exceeds the acceptable
value (Merging Unit Delay setting). The IED raises a 9-2 Sample Alarm when any one of the binary flags is 1.
SAV Questionable 18 54
00000000 00000000
00000000
This is a data cell with 24 binary flags. It indicates the status of the IEC 61850 Quality attribute ‘Questionable’ in the Sampled
Value frames for each of the analogue channels. The channel assignment depends on the IED.
SAV Invalid 18 55
00000000 00000000
