Scan Engine & EtherCAT Custom Device Feedback

[Sankar_Longhorn]

Devin,

I did use labVIEW 2012 SP1 for creating the bit file. Towards the end of my bit file compilation, I got an error like this. I am not sure why. I do have NI RIO 12.1 on MAX. Compilation was successful though. Thoughts ?

Hi Sankar,

That error looks like you tried compiling by clicking the "Run" button in the VI.  You should instead go to the build specification in the project and right-click to build.  But, looking at the screenshot, it looks like the file compiled successfully, so that shouldn't be the problem.

When you get the 1124 error on deployment, can you check the RT console output?  You can go to http://targetipaddress and then click the "Console" icon on the left to see the RT target's output.  It might give more information about what exactly is not loading correctly.

Devin,

This is what I see there. Almost idenitical to log status.

Hi Sankar,

The problem was that the VIs used to read/write fixed-point UDVs on VxWorks were incorrectly compiled for PharLap.  Version 4.0.4 should fix the problem.  You can download it here.

Let me know if that fixes your problem!

[Sankar_Longhorn]

Yes that did the trick ! Thanks for the help Devin. Appreciate it.

Regards,

Sankar

Hi,

I just have some general use recommendations regarding documentation.

• Currently the Command and Status channels do not have descriptions. It would be great to document them. As an example, people may not know that a Scan Mode State of 3 indicates that it is faulted. (1 - Configuration, 2 - Active, etc.)
• Fault recording would also be useful. At this point if someone experiences a fault they must open Distributed System Manager to review the fault. If possible it would be good to print to the console or have an additional channel which returns the current faulted code so that the user to take the appropriate actions. If this isn't possible, it would be useful to document on the support page that you can use DSM to gather fault information or even why one would receive faults.
• Lastly, the Cyclic Data Bandwidth default is 40 in the latest version but the help .chm which loads on that page states that it is 20.

Thank you and great work!

I noticed that I am unable to apply a scale to channels defined under the scan engine custom device.  Is there a way to do this or are scales not supported?

Thanks for your help.

[StephenB]

Hmm they should be scalable. I just double checked the code and we are setting them scalable. Is there a specific module you see this problem on?

[StephenB]

I can scale 9205 channels

I defined a scale in the system def.  I can right click a channel under my FPGA and get a menu that asks me to "Select Scale" (first image).  Also notice the scale icon appears in the tool bar.  If I select a channel under the ethercat, the scale icon goes away and there is no right click menu (second image).
