CANopen Fetch from Data

Solved!
Go to solution

I have dragged this subvi Fetch from Data  of CANopen.

But i got the problem with "One or more polymorphic instances have a connector pane that is incompatible with the connector panes of other instances."

How can i solve it?

Hi Zhangfy,

 

then you have accidently changed one instance of that polymorphic VI even though you should NOT CHANGE VIs from (NI-supplied) libraries…

  1. Use your SCC system to revert back to a working version of this VI. When you don't use any SCC system: start using one!
  2. Pick a backup with a working/unchanged version of this VI. When you don't use backups: start using them!
  3. Reinstall the CANopen driver with all VIs…
Best regards,
