è For most applications a send-period of 1ms is
recommended.
The update-rate is independent of the number of
channels. It does not matter, whether 7, 23 or 41
static measurement channels are used.
Traditional systems often provide an update-rate, which
depends on the number of measurement channels. Thus it
is far lower than it appears at first glance. This limitation
does not apply to the Irinos-System.
Please not that all update-rates above are estimated values
but not guaranteed. In case a data frame gets lost, a longer
break between two updates may occur. If a guaranteed
sample-rate is required,
dynamic measurement must be
used.
8.8 Dynamic measurement
è Tip: various examples are available for using dynamic
measurement.
8.8.1
General
A dynamic measurement is always limited in time. It is usually
started before the beginning of a dynamic measurement process
(e.g. before starting a motor). The maximum time allowed is 1
hour, which is just a theoretical value. Usually it lasts less than a
minute.
There are two types of dynamic measurement :
o
Using time-triggered dynamic measurement, all selected
measurement channels are sampled simultanesouly in equidistant
time-spans. It is possible to sample 10.000 values/s per channel.
o
Using position-triggered dynamic measurement, all
measurement values are sampled simultaneously in pre-defined
position-distances. This requires a measurement channel, which
provides the position information. For example an incremental
