Note
When analysing the annunciations of the SIPROTEC device in the
PROFIBUS-DP master, it should be noted that due to the cycle period of
the PROFIBUS-DP system or due to the cyclic processing time of a
PLC, temporary changes of an annunciation's value (ON and OFF within
one cycle) may eventually not be recognized.
This applies in the first place for protection annunciations.
Protection annunciations which indicate the status protection pickup, are
active only for the period of time of the protection pickup.
The parameter M
INIMUM
address = 210) allows setting of the minimum duration of the TRIP
command.
This time setting applies to all protection functions which may cause a
TRIP signal. After a protection TRIP, the corresponding protection
annunciations transmit the value ON for the programmed minimum time
duration.
