Re: CANopen question

Hello John,

there is no standard way in CANopen (similar to J1939 Address Claiming)
for resolving node-ID collisions. 

However, there is the possibility to send an EMCY message with code
8150h which denotes a CAN identifier collision. We use this EMCY
code in our CANopen protocol stack in order to signalize collision
of Tx PDOs, SDOs, etc. It does not automatically solve the conflict,
but it helps to investigate the source of the problem (which is the
system integrator).




Greetings,
Uwe
