Error 50256 When Trying to Programmatically Create DAQmx Scale

[PatW]

I'm trying to use the Custom Scale feature of DAQmx to implement scaling on an analog input task, but I'm receiving the following error:

Error -50256 occurred at DAQmx Create Channel (AI-Voltage-Basic).vi:1780002

Possible reason(s):

The specified feature has not been implemented for this environment. The operation could not be completed as specified.

Task Name: test

This is occuring on a Windows 10 machine running LabVIEW 2018 and DAQmx 19.1. It only occurs when I try to use the DAQmx Create Scale vi- if I set a scale up in MAX and use that instead, it seems to run fine.

Hi PatW,

Can you post your code or a screenshot? That will make it easier to provide specific recommendations.

Best,

Figured out the issue. I was trying to type cast the channel name to a string, then append "_scale" to it. When I just used a generic string for the name instead, i no longer received the error. It would appear that type casting the DAQmx channel name to a string is not supported.
