What are CANopen Library error codes?

[John Voulgaris]

I am trying to diagnose a problem with a Labview application I have created using V8.2 and the CANopen Library.  I am getting an error from the SDO Create CANopen VI but I have no way to interpret it.  Looking at the CANopen Error Handler VI, it appears that the possible error return values from the library are 1 (the error I am getting), 0x1500-0x1503 and anything negative.  Is there any document that describes these error codes?
 
Thanks,
John Voulgaris

John,

Codes 0x1500 to 0x1503  (0x1502 actually) are CANopen specific error codes.
The Installation of the CANopen Library should have put a file named
CANOPEN-ERRORS.TXT int your  ...\user.lib\errors\ directory, looking like this:

<?xml version="1.0"?>
<nidocument>
<nicomment>
Error codes for the CANopen VIs
(5376-5378)
</nicomment>
<nierror code="5376">
Invalid CANopen object reference. Object does not exist.
</nierror>
<nierror code="5377">
Invalid CANopen object reference. Object has the wrong type.
</nierror>
<nierror code="5378">
An SDO transfer is already pending for this device. A device cannot handle more than one SDO transaction at a time.
</nierror>
</nidocument>

Everything else seems to be "standard" LabVIEW error code, 1 meaning "An input parameter is invalid".

You  should get an explanation of all  codes if you put the
error cluster on a frontpanel, right click on the code and then
select  Explain Error.
