For displaying this pages, LabVIEW does need certain VIs.
The error message can occur, when some of the needed VIs are missing.
To check, if the VIs are existing on your computer, go to C:\Program Files (x86)\National Instruments\LabVIEW 20xx\vi.lib\LabVIEW Targets\FPGA
, where you have to exchange 20xx
with your LabVIEW Version.
The VIs needed for displaying the Online Slave Device State are in the subfolder ECat
If the folder is missing, try the following:
- Uninstall the NI-Industrial Communications for EtherCAT driver and install it again.
- Copy the folder from a computer with a working NI-Industrial Communications for EtherCAT installation.
