14 Data Logger and Transmission of Data FLUXUS G80x
UMFLUXUS_G8V4-6-1EN, 2018-10-10 105
The line \DATA is transmitted next followed once by the column titles (see Tab. 14.3) for the corresponding channel. The
measured values are transmitted afterwards.
In every storage interval, one data line per activated measuring channel is transmitted. The line "???" will be transmitted if
there are no measured values available for the stor-age interval.
The following data columns can be transmitted:
Online Transmission of Data
Columns will be created for all quantities that appear during the measurement.
As the totalizers cannot be activated for the physical quantity flow velocity, these columns will not be generated.
Offline Transmission of Data
During the offline transmission of data, columns will only be created if at least one measured value is stored in the data
set.
Example: \DATA
A: \*MEASURE; Q_POS; Q_NEG;
B: \*MEASURE; Q_POS; Q_NEG;
Example: With a storage interval of 1 s, 10 lines with "???" will be transmitted if the measurement has been re-
started after a 10 s interruption for the positioning of the transducers.
