I am fairly new to the X-Net API and programming for RT targets, so I apologize in advance if this is an amateurish question. However, I've combed through the forum, knowledge base, and getting-started guides multiple times without much luck.
I have a 9862 module in a cRIO 9045, with which I am trying to record CAN signals. For prototyping and ease of logging, I elected to use the signal input waveform session mode. I have also created a database, which I have successfully (as far as I can tell) deployed to the RT target using the database editor.
My question has two parts, corresponding to the two ways in which I've tried creating the session.
- Project session: I tried creating the session under the RT target in the project. Database and interface have been specified, with the static session reference piped into my acquisition and logging loop. However, when I try to deploy the project, it only makes it as far as 'Deploying X-Net Session' before stopping and returning "deployed with errors." The same thing happens when I try porting the X-Net project-session examples to my cRIO target. If I remove the project session, the rest of the project deploys successfully. What is going on here? I can find no specific examples or documentation on creating a project session for an RT target - is that not a supported method?
- Run-time session creation: To get around the deployment problem, I tried creating my session at run time, but here's where my unfamiliarity with X-Net hurts me. I cannot, for the life of me, understand how to specify the database I've deployed when creating a session. The 'create session' VI has a 'signals' input, but how does one specify a list of signals if a database hasn't yet been loaded? Does X-Net automatically use whichever database(s) are deployed on the RT target and, if so, what about when multiple databases are deployed? The X-Net examples aren't particularly informative when it comes to this.
I apologize again if these are dumb questions, and thanks in advance for any help.
