Measurement / Control via MscDll
Parallel data exchange via the MscDll
In traditional systems, data must be read from one or multiple
measurement cards by using their APIs. Since the measurement
cards are often produced by different manufacturers, different APIs
with different strategies must be implemented into the
measurement software. Using the Irinos-System, all data is available
via a single interface: the MscDll. The only thing which varies is the
number of measurement channels and of the in- and output bits.
The most important difference to traditional systems is reading the
measurement values:
The MscDll transfers all measurement values in background. They
are not directly read from the hardware. Instead the MscDll updates
them in a predefined interval. The application software is informed
each time new data is available.
8.3 Static vs. dynamic measurement
The MscDll distinguishes between two types of measurement: Static
measurement and dynamic measurement. Both can be used in
parallel. Following a short introduction shall be given. More
