[Cause]
A network communication error occurred on a network connected to a given circuit board.
[Countermeasure]
Check that the board and device baud rates are the same. Check the cable connections to both the board and the device. Check the network wiring, including terminating resistors. Check that the correct device definition is selected for devices on the network and that the parameters are correct for user-defined devices. Turn off power to both the controller and the DeviceNet network, then cold-start the controller. Turn on network power at the same time.
