I have been using LabView for about 3 months now and have managed to reduce the execution time of an VI from about 20 ms to 3 ms. However, the requirement is less than a ms.
We are looking at only the Torque measurement (Drehmoment). The data is acquired from a Kistler Torque Sensor and then passing through an NI M Series device (SCB-68) comes into the workstation. The data is acquired using DAQmx (can be seen in Multi Global Channels) and then displayed. Now a point is displayed every 3 ms for Drehmoment on the chart. However, I need it faster (about 0.6 ms per point).
Is there something which is slowing down this display.
Please have a look at the attached VI's. A solution needs to be obtained quickly so please respond asap.
Do you use a Real Time System or Windows?
If it's Windows, you're restricted to 1 ms by the the System Clock when you are lucky.
But there might be a way to forward the "timing" to your hardware.
What Hardware (M-Series) do you use?
With this information I could help you to optimize your VI.
I am using a Windows 7 system....with 6 Gb of RAM..
I tried doing it with only the Torque measurement and I got measurement values at every 40 microsec...approx.
But when I put in all the values it shows 3ms.
I am using a SCB-68 M-Series device...pic attached.
Thank you for the quick answer!
Your sensor is connected to the NI SCB-68 I/O Connector Block.
I already understood that, but what card is the connector connected to?
