PXI 8531 Change Node ID

[J_Print]

Hello guys,

I have a PXI-8531 which is connected with an analogue transmitter modul. (Transmitter-Modul: http://www.microcontrol.net/fileadmin/maindownload/manual/hb_mcan_trs_v2r00_de.pdf). I want to change the Node ID of the modul, so I tried to use the CANopen Library toolkit "CANopen Node-ID Change VI". Unfortunetely I don t know how to use it correctly and I didn t found a helpful example.

In the apendix you will find an attempt to integrate this toolkit in the CAN open example CANopen_SDO_Read.vi.

The output error (2147136874) says that the error code is undefined.

I would appreciate any help!

Cheers,

Jason

Hi Jason,

according to CANopen error codes documentation your error code describes: The interface object already exists. You must specify another CAN interface to create an interface object.

You can also check Troubleshooting CANopen Applications manual for further help.

Possible solution: if you want just to change Node ID (and you don't require to do it programatically):
1. Right-click your target.

2. Choose CANopen utilities.

3. Choose Change Node-ID

Hope this helps.

Regards,
