Measurement / Control via MscDll
information is provided in the respective chapters (-> static
measurement / -> dynamic measurement ).
Using static measurement, measurement values are updated
continuously. The measurement values are neither synchronized nor
transferred in realtime. The typical update rate depends on the
number of boxes and the configuration. The range is 30-100 Hz per
channel. For many measurement applications, this is the perfect
choice.
The implementation of the static measurement is very easy. Once it
has been started via the MscDll, measurement values are
periodically requested from the Irinos-System. These are copied into
a buffer, which has been provided by the application before. If new
measurement values have "arrived", the application is informed.
These can be read by the application at any time.
Often the static measurement is also used to achieve an online-view
of the current measurement values.
The dynamic measurement is used for synchronized realtime data
acquisition with a maximum sample rate of 10.000 samples/s per
channel.
A dynamic measurement is always limited in time. Typically its
duration is equal to or less than one measurement cycle, which
correlates to a few seconds. Each measurement value is either
related to a specific time or position (e.g. angle). While the
measurement is active, all measurement values are stored in the
internal memory of the Irinos-System. During and after the dynamic
measurement, the values are transferred to the application software
via the MscDll.
Dynamic measurement is for example used to measure the form of
an object (e.g. roundness). Usually it only uses a limited number of
measurement channels. A simple roundness measurement may
require even only one measurement channel. The maximum number
of measurement channels, which can be used for a dynamic
measurement simultaneously, is limited to 32.
Before the start of a dynamic measurement, various parameters
must be defined, like the measurement channels used, the start
time, the number of values measured, etc.
