Signal Output
3.7.3.1
Transfer of the Configuration Value
The output or change of signals at an output channel of the ES930.1 is trig
-
gered by a configuration value that is transferred with a STIM packet.
3.7.3.2
Response Time and Update Rate
For MC applications, the response time or update rate of the ES930.1 for the
signal output is approx. 300
ms. This time is determined, among other things,
by INCA. If an assigned input signal is used as stimuli, the outputs of the mod
-
ule are updated with the aforementioned rate.
3.7.4
Synchronization of the Model Process of the ES910 Rapid
Prototyping Module
If events were defined for the ES930.1 module and the module is combined
with the ES910 prototyping module, the model process can be synchronized in
the rapid prototyping module to the events and the input signals of the ES930.1
captured at the same time.
3.7.5
Limited Data Acquisition
If the input signals of all channels of the ES930.1 should be captured at the
same time, the module cannot capture the signal exactly at one channel.
If the user should attempt to capture all the signals/channels with a ES930.1
configured accordingly, an attempt is made to optimally distribute the existing
resources within the module. The configuration software monitors this selec
-
tion, provides support for the deselection of the non-required resources and
informs users about the changed setting.
The user can change the default setting predefined in the configuration soft
-
ware and select any other channel which will then be excluded from the signal
acquisition in the described case. The configuration software supports the user
in this selection of non-required resources to ensure the desired data acquisi
-
tion at the other channels.
3.7.6
Limited Data Transfer for MC Applications
If the ES930.1 module is operated at high rates for MC applications, it is possi
-
ble that the PC can no longer process the data transfered by ES930.1 and dis
-
cards data.
The Flow Control function can be used to prevent these data losses (packet
losses) between ES930.1 and PC. The Flow Control function is supported by
the ES930.1 module from HSP V9.7.0.
If data losses should occur between ES930.1 and PC, the user in INCA receives
a message after the measurement is complete.
NOTE
For input signals with higher base resolution (faster raster), the data are dis
-
carded or only the most current value is transferred.
