Application manual
local communication module, LDCM. The parameter shall be set to 2 when
transmitting analog data from the local transformer module, TRM. When a merging
unit according to IEC 61850-9-2 is used instead of the TRM this parameter shall be set
to 5.
RemAinLatency: Remote analog latency; This parameter corresponds to the
LocAinLatency set in the remote IED.
MaxTransmDelay: Data for maximum 40 ms transmission delay can be buffered up.
Delay times in the range of some ms are common. It shall be noticed that if data arrive
in the wrong order, the oldest data will just be disregarded.
CompRange: The set value is the current peak value over which truncation will be
made. To set this value, knowledge of the fault current levels should be known. The
setting is not overly critical as it considers very high current values for which correct
operation normally still can be achieved.
MaxtDiffLevel: Allowed maximum time difference between the internal clocks in
respective line end.
