Hello,
I developing a application for acquisition sensors and treatment of data.This application uses shared variables and Modbus data available in labview.
My application running normally, but when I try to deploy in real-time application, it don't give the same informations and I have a file error that is attached parts.Shared variables and modbus data are not compatible with real time application?
Thanks for your help

My hardware is NI CompactRIO 9074. My data is temperature data, current data, (data 0-10V. these data are acquired in a while loop then I assigns each parameter coefficient. Then I put them in shared FIFO variables, and I also published in modbus.dans one second while loop, I receives the data shared variables and I recorded in a text file type csv).
I'll give you a csv file. The results are completely different, there is still zero as a value when one is real time.

File error? That just screams you are trying to write to the C drive, which does not exist on an RT system.

I think the cRIO 9074 OS is VxWorks, so it should have C drive, but the path syntax is different than WIndows, i.e. /c/logs/errors. I was using similar path to log errors on a cRIO 9024

Working with File Paths on Real-Time Targets
I've seen lots of people ask where their files are because they are writing on the cRIO and not their Windows machine.

My Project, real time application and file generate after deploy my real time application are attached file.
Thanks
