Hio all, I’m starting up an IRB2400 and i’m having troubles with the devicenet bus.
The error 71301: Bus off, DeviceNet bus communication failure (Devicenet 4) appears usually, the robot continues working fine.
I confirm the error and later comes up, event :
71390: The DeviceNet bus have recovered from bus off, The DeviceNet bus have recovered from bus off state.
I think that the Devicenet4 communicates the welder machine with the RobotWare, and i’ve got problems there, because I can’t change the weld type through the RobotWare Arc.
Actions.
- Whole bus has 24VCC.
- The resistors are correctly connected.
- The cables are correctly connected.
- No idea about topology?
- I restarted few times.
Hope you might help me.
Greetings.
