NMT Message

[R_J]

Hi All

I am using CAN open protocol.I have to use NMT messages using either CANopen Labview library functions or CAN APIs.

Can anybody tell me the concept of NMT messages & how to use them ?If anybody is having any example VI of NMT messages them please post it.

Thanks in advance

Hi J,

The help document discusses both NMT and LabVIEW using the CANopen protocol. Have you seen this document before? You can open it and click on the "Search" tab and search for NMT. The entry called "Network Management (NMT)" discusses NMT in LabVIEW. It references the LabVIEW VIs to use there. If you click on the VI name, you can get additional information about each of the VIs. Further help pages in that document discuss the various LabVIEW functions. Unfortunately, I do not have any examples to give you, but hopefully this will get you started.

Please post back if you have any questions!  Best of luck to you!

Hi,

Attached you can find a simple example for the NMT command handling using the CANopen Library for LabVIEW. For SDO communication you nead at least the "preoperational" state. For PDO communication you need to start the node. You can start all nodes (node ID 0) or a perticular one (node ID X).
