3rd Party EtherCAT Module Fails

[mtitoo@archer.com]

Getting this error in 2024-Q3 VeriStand when trying to scan for 3rd Party ECAT devices. Saw this bugfix that was committed 2 days ago (https://github.com/ni/niveristand-scan-engine-ethercat-custom-device/pull/265 ) and updated Custom Device to the latest but still no avail. VeriStand 2023 this functionality works. Any suggestion?

Looks like PXIe- 8842 ethernet port is not compatible with ECAT driver as of now. Will be closing this post.

Installed ECAT compatible ethernet card but still the issue persisted in VeriStand. Looks like the issue could be the latest ECAT driver. Tried to add ECAT device in LabVIEW project and initially could not. It failed to detect slave device. Tech support pointed me this bug ECAT-2023-q3-known-issues. The workaround was to copy the XML files into

• Windows Path
  • C:\Program Files\NI\LVAddons\niecat32\1\resource\Framework\Providers\indcomecat\DD
  • C:\Program Files\NI\LVAddons\niecat64\1\resource\Framework\Providers\indcomecat\DD
  • C:\Program Files (x86)\National Instruments\Shared\IndComECAT\DD
• Linux RT path:
  • /var/local/natinst/IndComECAT/DD/ 

At this point I could add and read PDOs from the 3rd party HBM torque transducer as expected. But when went into VeriStand mode, that original error showed up. Still in touch with NI tech support for a resolution. Once I have it, will update this post.

Here is the fix.

1. Manually add Registry key "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\National Instruments\LabVIEW Run-Time\22.0".
2. Add a variable "Path" with value "C:\Program Files (x86)\National Instruments\Shared\LabVIEW Run-Time\2022"
