1. WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO SERIAL
2. WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO PSP

I have never gone in and explicitly configured anything pertaining to "hybrid mode" on this system. With 16 DMAs, the 9068 seemed to be forgiving enough to not need to worry about utilizing both.

WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO PSP

It's brought in through I/O server, presumably scan engine, or however the PSP process within the SVE that maps the 3rd party slave address abstracts that away.

WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO SERIAL

I don't currently run any code in my FPGA target VI that accesses the serial Modbus data. If there's anything I can discuss to advance troubleshooting on this, let me know. Enable Secure Shell (SSH) Logins Rebooting the cRIO-9031 with this setting on starts sshd on the cRIO-9031. Disable FPGA Startup App Rebooting the cRIO-9031 with this setting on prevents autoloading of any FPGA application. Add your target's IP address or Host Name in the appropriate destination field. Open your terminal client and specify a SSH connection. Save your changes and the target will reboot. I will continue to monitor this deployment throughout the day and, if the error remains resolved, I'll provide an additional log file if you think that will be helpful. Rebooting the cRIO-9031 with this setting on prevents any LabVIEW startup applications from running. Check the box by Enable Secure Shell Server (sshd) in the Startup Settings window. I have cycled the system about 30 times and run through the application in an appropriate test environment. I will post results here after toggling it to wait.Īs an update, I changed the timed loop to a standard while loop with an equivalent Wait, and everything appears to be working consistently. I'm not sure how this would pertain to the -52018 error code occurring at the FIFO write, which doesn't even execute here, but thought that maybe something is causing issue if I'm running it and not opting to wait. This is just to get an initial value to some other functions prior to starting. I have my Run toggled to not wait until done, then immediately make 1 pass through it before it's handed off to the main application cycles. One change I made recently was one initial pull of data from the FPGA just after I load the bitfile, reset and run it. It mainly occurs when I deploy the code / run at startup to the 9068, and whether or not I get it is intermittent.Īttached is a condensed version of my init thread, which runs just prior to my main VI. I haven't had much issue running the cRIO RT host VI from my laptop, so when I probe for issues, I never see them. This FIFO write has been there functioning for years without issue, but this error is new. When creating a LabVIEW Real-Time application for CompactRIO. The operation could not be completed as specified," but rather just where it occurs: the Invoke Method: FIFO.Write in one of my VIs. In this architecture, the FPGA is performing low-level control while acquiring. My error message does not specifically say "A hardware failure has occurred. I'm not sure how the information in these threads applies to my particular case, so I thought I'd ask if anyone's encountered it. Searching the forums, I see a couple threads with this error pertaining to the PXi system, but none to the cRIO. I am trying to determine what a particular error (52018) means but have very little context to help understand it.
