PID parameters

[jspaarg]

Is there a VI to read the PID parameters from a 7344 motion card?

Hey jspaarg,

Please refer to the following Discussion Forum post 7344 PID where you will be able to find an answer to your question.

Unfortunately, the short answer is no, there is not a VI that will read the PID parameters.

Thanks DJL.

Can I write the FLASH on the 7344 from LabView, or do I need to use MAX to write the FLASH?

There seem to be some LabView VIs to support that, but the help for them is sketchy and I don't want to damage anything.

Slightly off-topic, is it better to trust the config stored in the 7344 FLASH, or to load all parameters when the application launches?

Thanks.

Hey jspaarg,

You can initialize the controller from either LabVIEW or from MAX. You can also load parameters from both LabVIEW and MAX. There is further help on the LabVIEW VI's in the VI Help document, and even more in help in the Motion Documentation that comes with the driver software. Don't be worried about damaging the board by loading parameters or initializing the controller from LabVIEW, as they can't do damage to the board. Last, it is recommended to have the parameters loaded on the controller by using MAX as it will be less for your program to do, but if you want to double check and make sure that your parameters are loaded the way you want each time you run your program, then you can do this in LabVIEW when your application launches.

I hope this answers your questions. Please let me know if you need further clarification. Thanks and have a great day.
