Error creating TASK

[michele.santucci]

Hi, I recently updated my system to version 2026 Q1 (LV and all related tools, including DAQmx, NIMAX, VISA, etc.). I was previously using LV 2013 with all related tools aligned, everything runs on a Windows 11 workstation.

I primarily use an NI 9184 chassis with three modules installed: NI 9401, NI 9403, and NI 9205, but the same problem occurs with an NI 9185 chassis as well.

I'm experiencing very strange behavior when importing a cDAQ TASKs within NI-MAX.

I'm attaching the NI-MAX configuration file (in .ini format).

After importing the .ini file, if I check one of the output task, I find this:

NIMAX task property

the error details report this:

"One or more of the inputs to this step are not selected. Insert a step before this step which has an output that matches the type of signal this step requires."

I'm really having trouble understanding what this means because:

1) I'm creating an output task and want to assign a value at runtime (in LabVIEW), so why would I connect another input/output to this channel?

2) It's impossible to follow this hint... I can't add an input step in the same task as an output task; adding a second output step makes no sense (and doesn't work).

3) The NI-MAX CDAQ task creation/import with the same exact features worked with all previous versions of NI-MAX, DAQmx, etc. (with the same hardware).

P.S. The same error is reported even if I create the activity manually, so it shouldn't be a problem with the .ini file format.
