hOW CAN i SAVE CALCULATED DATA WITH expressVI

[Jonas Weiß]

Hello,

I want to save calculated data with the express Vi "write to measurement".

Therefor I sent the calculated data from formula node to an array and then to the express VI "write measurement data"

The result is al three measurement rows are in one column. And it saves only the last point.

What could I do?? Do you have any good ideas?

Thank you very much

[Jonas Weiß]

Hi jonas,

     I am not clearly understood your question. The result is al three measurement rows are in one column- so now you having 4 data points one aquired data and three calculated datas, u want put 4 datas in the same column? and repeat the iteration?

I want to save the calculated datas as well as the datas from the measurement.

Example:

X_Data [time in sec]	pressure 1	pressure 2	pressure 3
1	0.1	0.1	239
2	0.2	0.1	400
3	0.3	0.1	561
4	0.4	0.1	722
5	0.5	0.1	883
6	0.6	0.1	1044
7	0.7	0.1	1205
8	0.8	0.1	1366
