All Irinos-Boxes have the same system time, called "ILink-Time" (Unit: µs). Time-deviations between different Irinos-Boxes, which cannot be completely avoided, are constantly eliminated. The end user does neither have to parametrize nor to check this. In practice these deviations are less than 200 ns.
The data acquisition of all Irinos-Boxes is started simultaneously based on the ILink-Time. The measurement values are stored in the internal memory of the Irinos-Box and then transferred to the Master-Box. Here they are merged to a single block of measurement values. This allows a fast simultaneous data acquisition of all channels.
The realtime capability is independent of the number of measurement channels, because each Irinos-Box has its own buffer for measurement values. |
