upgrading VIs from NI-DAQ Traditional to DAQmx

[jtaclas]

I need to upgrade a few VIs that are written for use with Traditional NI-DAQ to DAQmx for a hardware upgrade from an E-series DAQ card to an M-series.  I have very little experience with LabVIEW, but have managed to use some useful guides to help with the transition.  I am, however, having trouble with a few of the inputs of many of the counter and pulse VIs.  Particularly, CTR Group Config and CTR Mode Config, as well as CTR Pulse Config, and signal routing with PFI lines.  I was wondering if there are any useful reference guides or books that could outline such transition.  I have found a few short guides online, but I do not feel they completely encompass the subject of timing and counters.

Hi,

There are some great tutorials about transitioning from Traditional NI-DAQ (Legacy) to DAQmx. Here are the links to 3 of them and a knowledgebase:

Transition from Traditional NI-DAQ to NI-DAQmx
Advantages of NI-DAQmx
Learn 10 Functions in NI-DAQmx and Solve 80% of Data Acquisition Applications
NI-DAQmx and Traditional NI-DAQ Counter VI Comparison.

Also, more information on counters in DAQmx can be found in the NI-DAQmx Help. Go to Start >> All Programs >> National Instruments >> NI-DAQ >> NI-DAQmx Help. Once you have this open, go to Common Applications >> Counter Programming Flows. Also, specific information about all DAQmx functions is in this document.

There are also counter shipping examples for DAQmx. These are located in the LabVIEW Example Finder under Hardware Input and Output >> DAQmx >> Counter Measurements. I hope that you find this information helpful.
