Hello,
I am fresher in DAQ related project. Please, help me to create this project. I have to perform 3 tasks and I am using DAQ assistant to create virtual NI9181 chassis and NI 9203. I have to use these 2 component.
Here is my tasks:
1) Scale generated signals between user defined ranges. (My output given by NI9181 is between 0-20mA. I want to scale it between userdefined max and min value.)
example: if output is 2mA and user defined max and min value is 0 and 10 then result should be 1.
2) I want to plot data of 8 channels into one graph
There are two requirements for this: 1) on X-axis graph should show timestamp on which date of data generated should be there
2) Graph should show all 8 channel data in one graph and with previous data
SORRY if I am sounding bit lazy and stupid but I am trying to perform this task but I can't do it.
THANK YOU SO MUCH IN ADVANCE

1) Create a DAQmx scale. A linear Scale ( y = Mx + B) would use M = 62.5 and B = -0.25 to scale Amps to MyUnit and you should specify the scaled unit since it will populate to the CHART Y axis. For a Logarithmic scale the math is left to the student as an exercise.
2) Don't use a Graph use a Chart.
Try for an A+
