Hello friends,
I'm new to the H series and CanOpen. I found the CanOpen Node stack sample structure on Github. I did some experiments on this. But I cannot see the data.
Data always comes as zero and dID =723, but my ID is 123. Can anyone help me on how to send the data and manage TPDO? I cannot find the data in the objects in the OD.c file. Thank you in advance.

Hi,
0x700 + NodeID is the heartbeat message, Node ID can be 0x01 to 0x7F, si probably 0x723 is OK (if 123 is in hex).
Please get your self some documentation on how CanOpen works (for example from CAN-CiA.org, or as simple introduction: https://www.nikhef.nl/pub/departments/ct/po/doc/CANopen30.pdf)
