diagnostics
Red
It indicates the following faults on the Fieldbus side:
Flashing 1 Hz - Configuration error: the IN/OUT area size set at board initialization is different
from the size set during the network configuration.
Flashing 2 Hz - Error in the user parameter data: the size/content of the user parameter data
set at board initialization is different from the size/content set during the network configuration.
Flashing 4 Hz - Profibus Communication ASIC initialization error.
OFF - No present problems.
On-line Green
Indicates that the board is on-line in Fieldbus network:
ON - The board is on-line and the data exchange is possible.
OFF - The board is not on-line.
Off-line Red
Indicates that the board is off-line in Fieldbus network:
ON - The board is off-line and the data exchange is not possible.
OFF - The board is not off-line.
NOTE!
When power is applied to the drive and both on-line and off-line LEDs on the Profibus DP board flash
alternately, then a network address configuration or an installation problem may be present.
„
Check the installation and the network node address.

Use of related Profibus DP/Parameters of the MVW3000. See Item 9.1.6 Fieldbus Application/
MVW3000 Related Parameters on page 9-7 .
9.1.3 DeviceNet
The DeviceNet communication is used for industrial automation, mainly for the control of valves, sensors, input/
output units and automation equipment. The DeviceNet communication link is based on a communication protocol
“broadcast oriented”, the Controller Area Network (CAN). The physical medium of the DeviceNet network consists
of a shielded cable comprising a twisted pair and two wires for the external power supply. The baud rate can be
set to 125 kbits/s, 250 kbits/s or 500 kbits/s.
Figure 9.7 on page 9-5 shows a general view of a DeviceNet
network.
