Post-triggering recording length V240 R, W 0...100%
External trigger signal's checksum V241 R, W 0...31
External trigger signal's edge V242 R, W 0...31
Checksum of external signal storing mask V243
b)
R, W 0...31
Triggering state, clearing and restart V246 R, W R:
0 = Recorder not triggered
1 = Recorder triggered
and recording stored in
the memory
W:
0 = Clear recorder
memory
2 = Download restart; sets
the first information and
the time stamp for
triggering ready to be read
4 = Manual triggering
a)
M1 can be used for broadcast triggering by using the unit address “900”.
b)
Parameters can be written if the recorder has not been triggered.
c)
The disturbance recorder requires this parameter to be set. The conversion factor is the transformation ratio multiplied by the rated current
voltage of the relay. If value 0 is given to this parameter, dashes are shown on the LCD instead of the primary values and the recorded data will
be redundant.
d)
This value is copied to parameters M81 and M82.
