Irinos Measurement System

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 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.
