5.4.1.3.8 Sensor sensitivity
The module always assumes a 100 mV/g accelerometer on the input. A different sensor resolution can be set using
register
"SensitivitySensor" on page 169
.
Example
Factor = 100 / (sensor sensitivity in mV/g)
All values must be multiplied by the calculated factor. This also applies to the analog characteristic values if the
characteristic value calculation is enabled as well as for uploaded time signals and amplitude spectra. Exceptions
are all characteristic values without units, such as
"KurtosisRaw" on page 177
,
"CrestFactorRaw" on page 175
and
"SkewnessRaw" on page 178
.

5.4.1.5 Register description
5.4.1.5.1 General data points
This module is equipped with general data points. These are not module-specific; instead, they contain general
information such as serial number, system time and heat sink temperature.
This module contains the following general data points.
•
FirmwareVersion
•
HardwareVariant
•
ModuleID
•
SerialNumber
General data points are described in section "Additional information - General data points" of the X90 mobile system
user's manual.
5.4.1.5.2 Function model 0 - Standard
The calculated module characteristic values are streamed from the module via Flatstream every 300 ms and pre-
pared for the user by Automation Runtime. If the streamed data is not collected by the next transfer, the charac-
teristic values of the next measurement are lost. For this reason, the maximum cycle time must be observed for
an error-free evaluation.
Analog inputs are provided as cyclic data points.
To help the user, all of the module's characteristic values – such as Flatstream handling for characteristic values, unit
scaling and so on – are prepared using Automation Runtime and then made available to the user,
see "Automation
Runtime support" on page 166
.
With this function model, it is also possible to upload data from the module via another Flatstream data buffer. Library
AsIOVib
is available for uploading the buffers from the module. For a description of the library, see "Automation
Help - Programming - Libraries - Direct I/O access - AsIOVib".
The option board can only be configured via the I/O configuration. No registers are permitted to be reconfigured
acyclically.
