Edit or information on counters

[Jack42]

Hi,

I am reading impulsion from an encoder.

I have a VI where there is a counter. I would like to know how to view information about this counter and if it's possible to edit it.

In fact, I would like to know if X2 or X4 encoding has been used, but I can't find the details.

Thank you very much,

Jack

Hi Jack,

Can you give us some more information? What vi are you using? Did you create it or is it an example? Can you post the vi here? What encoder are you using?

Hi,

The encorer is a Digital Encoder from Maxon.

The VI has been created from another person at my lab but who's not there anymore.

I can't post the VI, but I can send a printscreen of the interesting part.

In fact, a counter counts the impulsions in a timed loop. I would like to know the options of this task/counter. By example, if it's position, front counter, type (X2 or X4), counts per turn, etc...

Thank you very much again,

Jack

Hi Jack,

The DAQmx Read configured for Counter Single Sample Double simply reads the data in. Any settings are applied at the Encoder (which is a DAQmx Task). You can find the settings in Measurement and Automation Explorer under Data Neighborhood»NI DAQmx Tasks. You'll want to look at the help there for details of encoder settings. You can also create a New Task by right clicking on NI-DAQmx Tasks»Create New DAQmx Task.

Hi,

I tried your last suggestion and it's working for the task I created, thank you very much.

The only problem is that the task he created is visible in the Labview VI but not in the tasks in MAX...I don't have his computer neither the material (NI-ELVIS) he had. Is there a way to find without that ?

Thank you again!

Jack,

There isn't a way to find out those settings other than looking at the original task. You don't necessarily need the hardware though.
