Reinitializing IO variable

[craige]

I am using a 9411 pulse counter card and have been successful in configuring the card as a counter and reading IO variable in order to obtain this value. How do I reset the counter? I've attempted to use Variable Forcing but this only forces the value. I want an actual reinitalize the variable to zero and allow the count to continue.

Thanks,

Craig

Hi Craig , there is a similar forum about this topic in this link:

And here is the KB that mentions the same issue about the forum

Will My Counter Continue to Generate a Pulse Train after I Stop My Program?

Perhaps I am not describing my problem clearly enough. I am not using DaqMX to interface with my pulse counter card. I am using the Scan Engine which is hosted on my cRIO remote chassis.

It does not appear that LabVIEW RT provides a method for reseting this variable to ZERO. Again, i've tried to use the Force Variable (Functions >> MeasurementIO>>Scan Engine>>Forcing) to achieve this with no success.

Craige, take a look at this link and tell me if it resolved your question.

Close...but not quite. Apparently these features are only supported on a "localhost" machine which means my remote cRIO expansion chassis (9148) throws the following error.

Error -1950678945 "LabVIEW: The URL specifies a host name that does not correspond to the local host, but LabVIEW only supports the specified operation on the local host. You cannot perform the specified operation on a remotely hosted variable or stream endpoint."

The only option that remains is to maintain a functional global which holds the offset of the counter at the last "reset" I wanted. This way I can subtract the offset from the count and get the count I need. Unfortunately I'll also have to account for rollover. Thanks for the help.
