How do I read an analog signal from a PCI-7340?

[Juupke]

We are working with an absolute analog encoder that works from 0 to 5 volts. How can I read the analog signal in Labview? (version 8.0)

Thanks

To read analog values with a PCI-7340 in LabVIEW you should use Enable ADCs.flx and Read ADCs.flx (see screenshot). If you want to use the analog value to close the control loop, please refer to this thread. I have posted there a document that explains all the details, so please make sure to open the attachments.

Hi thanks for the message. I have made the VI but what is the number of the ai on the PCI-7340? 

[Jochen]

The number of analog inputs equals the number of axes. So if you have a 4-axis version (7344), you can use 4 AIs, the 2-axis version (7342) provides 2 AIs.
