Hello.
Thank you for posting to the NI Discussion Forums. 
The error 8 that you are seeing usually indicates one of two things are happening.  There is a great knowledge base article on this error at:
Why do I get "Error 8 Occurred at Open File" When Writing to or Reading From a File?<a href="http://digital.ni.com/public.nsf/allkb/F5D5F6798A9367CC86256F6C007A968D?OpenDocument" target="_blank">http://digital.ni.com/public.nsf/allkb/F5D5F6798A9367CC86256F6C007A968D?OpenDocument</a> In terms of the error 1 that you are seeing, this indicates that one of the inputs to the CANopen PDO Create.vi is invalid.&nbsp; I think that the PDO Configuration terminal on this VI requires a cluster of information, but you only have a constant integer.&nbsp; Try changing this constant to a control and filling in the appropriate fields on your front panel to correct this error.&nbsp;
Let me know if this helps!
