the ULx Read.vi in LabView 2019 is broken

[bfuchs]

i’m using LabView 2019 32 Bit (V19.0.1, SP1) on a Win 10 Enterprise PC (AMD Ryzen Threadripper PRO 3945WX 12-Cores   4.00 GHz, RAM: 32 GB).

I have also installed the MCCDAQ package to obtain the ULx library. 

Maybe it’s important to remark, that we had used until now the previous LabView Version (2016) and the following problem we get with a project, which was created in LabVie2016 and now opened with LabView 2019.

Especially the “ULx Read.vi” seems to be broken. The error Msg. is very general (s. screen03.jpg)

If I open the VI by double click, it is ready to run, there is no error Msg ?! (s. screen04.jpg)

I did also try to put this broken VI in a new empty VI, the result is the same.

Any idea what’s wrong or how can I fix this mistake ?

Please close out your VI code and load our ULx Read Dig Chan.vi example from ..\National Instruments\LabVIEW 2019\Examples\ULx\Digital\Read Values.llb. One by one, select each of your devices and perform a port read. Start with the USB-1208HS-4AO, and then try each of the USB-1024HLS devices. Let me know the results.
