Details or information

Hi,

I am modifying a VI that has a counter.

How can I know what type of counter it is?

I would like to know if it's a front counter, a position counter (angular or linear, X4 or X2) etc.

Also, is it possible to edit that?

Thank you very much,

Jack

Hello Jack,

it depends on the driver you use.

If you use DQAmx then it is possible, that you have a task in MAX which defines the behaviour of your driver.

If it is Traditional DAQ than you have to go throuh the DAQ VIs. Which are called and which parameters are used. Use the context help and detailed help of the VIs to find that out.

Hi

If it is GPIB / Serial you can usually use *IDN? or ID? through the visa drivers etc.  This replies with some information about its model number etc.  More information is available through more queeries / registers etc.  MAX is a good place to start.

Hi,

Thank you for your help but I can't find...

I joined a print screen of what I want information on.

This counter has been done for NI-ELVIS and I am modifying it with NI-USB 6211.

Thank you,

Jack

The task is a DAQmx task, I can edit it by right-cliking it, but I can't acces to the information...When I edit, the informations are blank.

Thank you,

Jack

Hi Jack,

The counters available on the USB 6211 are general purpose counters.  You can use the counters for edge counting, period measurements, frequency measurements, position measurements and to output a pulse train.  Refer to the user manual for the USB 6211 for details (look at chapter 10 for counter information).

If you don't see any information do the following test:
Start MAX (Measurement and Automation Explorer). Open My System >> Data Neighborhood >> NI DAQmx Task. This will show you a list of all tasks on your system. If encoder is not in the list you have to transfer it  from the NI-ELVIS system to your machine. You can do this in MAX using File >> Export... on the NI-ELVIS system. This will create a file with the extention .nce. Copy this file to your machine and double click it to import it.
