Hello all. Somehow I have locked my cRIO 9104 chassis to where I can not get my Windows VI to run. Attached is the error I get. I also attached my project. The last thing I remember doing before this happened was that I removed Network Streams from the RT vi and the Windows Vi. After that, I kept getting this error about the chassis being locked.
So my procedure is as follows:
a. Open Project
b. Open and Run Windows Main.vi
--c. At this point, I usually then have to open and run RT Main.vi in order to see data coming into Windows vi. However, I can't even get to this step now.
It seems something may be wrong with the shared variables. I took out the Rate Reading shared variable in Windows vi that was wired to the loop stop. After I did that, I would see values in the three Windows vi indicators, Flue Temp, Gas Temp, Gas Pressure. I don't know what is causing this issue now.
There has been one confusing behavior I am seeing. When I do step a, I get a screen saying things are deploying. After Windows vi starts running (and sitting there not showing anything), I open and run RT Main. I get another screen stating that things are deploying. Why do I get the double deployment screens? I'm thinking this is where my problem lies. Of course, it has been doing this ever since I started this project. It has never been a problem, I just wonder why this is happening?
Solved! Go to Solution.
Just a couple of troubleshooting steps:
-Make sure that your LabVIEW Real Time version is the same in both the Host and the cRIO.
-Try to create a new (from scratch) project and connect to your cRIO. Check if this error repeats.
-Backup all your files within the cRIO (if any). You could format your cRIO and re install the software on the RT.
Also, just to let you know, I was able to deploy using your project.
Ok, I checked the software, and they matched.
However, when I tried creating the new project and went to discover my target, I got an error message stating, "You can only have one chassis per controller. There is already a chassis associated with this controller."
Lsan, I am going to do the formatting of the crio. However, you said you were able to deploy my project. Can you tell me the steps you did to deploy it? I still feel I am doing something wrong when I deploy my projects, which may have led to the issue I am having now.
Ok, I formatted the cRIO and redeployed everything. It is functional again. I wish I knew why this happened, but at least it is working again. Thanks all.
