Installation and commissioning DATAEAGLE 3XXX X-treme
Chapter 6
– Filter time
6.3. Typical values for the filter time
6.3.1. Default
The factory setting of the filter time is 2 sec.
6.3.2. Recommendation for operation
Typical filter delay times in operation should be between
500 ms and 2 s.
The filter time should be increased under the following condi-
tions:
Slave has many I/O data
Many slaves should be accessed by the DATAEAGLE
Low transmission quality due to disturbance-afflicted envi-
ronment
6.3.3. Recommendation for commissioning
For commissioning it is recommended to select a value be-
tween 1 s and 4 s. This eliminates an early triggering of the
filter.
Afterwards the filter time may be reduced.
6.3.4. Recommendation for applications with Profisafe
In applications with Profisafe the filter time should be set
higher than the SIL monitor time at Profisafe.
Please observe:The higher the filter time is selected the
later as bus error is indicated (max. only as long as the
selected SIL monitor time). Please verify therefore if your
application meets the required safety criteria with the se-
lected filter time.
