NI-Switch Relay Add-On Feedback

[leomal80]

Hi,

I have just downloaded this addon for 2011 veristand version, the addon is recognized and i can see my relay module in the tree but if I deploy veristand project I get the error below on the file NI-Switch RT Driver VI.vi. Any help?

Details:

Error 1003 occurred at Project Window.lvlib:Project Window.vi >> Project Window.lvlib:Command Loop.vi >> NI_VS Workspace ExecutionAPI.lvlib:NI VeriStand - Connect to System.vi

Possible reason(s):

LabVIEW:  The VI is not executable. Most likely the VI is broken or one of its subVIs cannot be located. Select File>>Open to open the VI and then verify that you are able to run it.

Thanks

Did you install NI-Switch onto the RT target?

I solved updating all sw to 2014 version and using hardware discovery wizard. Thanks for your repy

Hello,
I'm having some trouble getting this custom device running with VeriStand 2014 on a real time controller (PXIe-8880/PXIe-1085 chassis) with relay modules PXI-2566 and PXI-2567. I am able to add the NI-Switch Relay custom device to the system definition, configure relay channels, and deploy to the RT target. However, when it loads on the target, I see an error on the RT display - "NI-Switch Relay CUSTOM DEVICE ERROR". There is no error displayed on the PC during deployment - it looks like it loads successfully and it continues to execute on the target. Any ideas about this?

Looking at the source, that error you mention is only produced at the end of the custom device's execution and only in the event of an error.

That VI will print an error code that looks like"

******NI-Switch Relay CUSTOM DEVICE ERROR******

Source: asdf.vi

Code: 93

******NI-Switch Relay CUSTOM DEVICE ERROR******

Are you saying you're just getting the ERROR string, without the source and code strings?  I don't see a scenario in the code where this is possible...

Since this occurs at the end of the code as well, it seems unlikely that the system will continue to load correctly and execute on the target.  When the execution continues, do you also gain control over the relays?  It seems like just based on the code paths I'm seeing in the source, we should take another look at the behavior of your system.   Do you have any more info about the error?

[dave6k]

Thor,

I checked the VeriStand log on the RT hardware and I did find some more information about the error. The system does continue to execute. I have not been able to confirm whether the relays actually work yet but I am working on that.

******NI-Switch Relay CUSTOM DEVICE ERROR******

Source:    niSwitch Initialize With Topology.vi<ERR>Invalid resource name.

If the resource descriptor is an IVI name, it must match the case sensitive entry in the IVI Configuration Store Starting DAQ waveform task loops...

Code:    Initializing Primary Control Loop...

-1074118654

Running system definition...

[Thør]

Well definitely in that case, go ahead and check the resource names you have set up in your system definition.  Those will need to match the same resource name that's under the target in MAX.  Do yours match?

[dave6k]

They didn't match. I fixed that and the error is gone. Thanks!

I'm getting a NI-Switch Relay CUSTOM DEVICE ERROR in the console window after my veristand project deploys.

Library Name: niswitchDAQmx.dll Code: -1074097808

I'm using Veristand 2015 SP1 with NI-SWITCH 15.1.1.  Below is a screen shot of the sofware installed on the host and RT Target

Hmm, what hardware are you using? I'd have to double check the source code but I believe it's using the DAQmx Switch API which could cause problems with newer hardware as is discussed here: http://digital.ni.com/public.nsf/allkb/639BFDBDB893EB5186257225007D0F58
