Got a complicated problem with one of our machines using DeviceNet. Im kinda new to this but what happens is that we have several nodes in the machine including a staübli 6axis robot. For some reason when the (deadman's switch) or servo motors recieve power it knocks all of the nodes off like they are loosing connection. If we exclude the robot in the equation the nodes doesnt fault. Even with an external power supply to the robots modules this happens. Does anyone have any idea what to look for here? Have tested all the other nodes as well but works aslong as the robot doesnt recieve power.
