Operated Network Interface (DPONI) Effective August 2009
CAUTION
DE-ENERGIZE THE DEVICE TO WHICH THE DPONI WILL BE
ATTACHED OR WIRED. OTHERWISE, IMPROPER OPERATION OF OR
DAMAGE TO THE EQUIPMENT MAY OCCUR.
The DPONI
The DeviceNet® Product Operated Network Interface (DPONI)
enables communications between a DeviceNet network master
station and a host device in a master/slave format over a
DeviceNet network. The DPONI is compatible with the MP3000 and MP-4000. The DPONI is powered by the host product
to which it is attached as well as by the DeviceNet network. The
DPONI uses opto-couplers to isolate the two power systems.
The DPONI communicates at 125 Kbps or 250 Kbps, selected via
a front panel DIP switch. 500 Kbps is fully supported. All
products on the DeviceNet network must be set at the same
communications (baud) rate. A baud rate setting with both
switches set to the “up” or “1” position is illegal. If they are set
this way at startup, the DPONI will not operate.
The DPONI has a bicolor network/module status LED that
functions in accordance with the DeviceNet specification. An
additional monocolor LED flashes while the DPONI is receiving a
message from the host device.
Figure 1. The Eaton Cutler-Hammer DPONI.
DPONI DeviceNet Basics
The maximum number of DeviceNet nodes is limited to 64.
Therefore, the DeviceNet protocol limits addresses to a range of
0 to 63, with address 0 reserved for the DeviceNet master.
Setting the address switches to any value greater than 63 is
Illegal. If the address switches are set to values higher than 63 at
startup, the status LED will be solid red and the DPONI will not
operate. The DPONI supports explicit mode and polled I/O
connections. Volume 3 of the CIP Networks Library provides details
of these communications modes.
The DPONI must be reset following an address change via the
address switches by removing power from the DPONI host
connection. This can be accomplished by cycling power to the
host device.
The DPONI allows monitoring and control only. Changing
setpoints is not supported. The DPONI is a Group 2 DeviceNet
product. Group 4 functionality is not supported.
Installation
The DPONI is designed to be installed, operated, and maintained
by adequately trained personnel. These instructions do not cover
all details, variations, or combinations of the equipment, its
storage, delivery, installation, check-out, safe operation, or
maintenance.
The installer must comply with the National Electric Code and
local codes or regulations, as well as safety practices, for this
class of equipment.

Networking
Master Device
The control station for the DeviceNet network must be a unit,
such as a PC or PLC, which acts as a DeviceNet master.
EDS files for the MP-4000 (MP-4000.EDS) and MP-3000
(MP3000.EDS) are on the disc shipped with the DPONI. The
latest version of each of these files is also available on the Eaton
Corporation Website (www.eaton.com).
Slave Device
A DPONI must be used as a slave device with a DeviceNet
network to provide communications with the MP-3000 or MP-
4000.
Simplified Wiring Rules
For complete wiring rules, refer to the DeviceNet Specification.
The DeviceNet configuration must comply with the rules for
trunk and drop cable configuration and length. The following list
provides the basic wiring rules.
• Terminating resistors are required on each end of the trunk
line.
• The trunk must be configured as a linear bus.
• Drop lines may be as long as 6 m (20 ft) and may contain
branches. The cumulative drop length for thin or thick cable
is limited to 156 m (512 ft) for 125 Kbps, 78 m (256 ft) for
250 Kbps, and 39 m (128 ft) for 500Kbps.
• The maximum total cable distance at all baud rates is 100 m
(328 ft) for thin trunk cable.
• The maximum total cable distance at 125 Kbps is 500 m
(1640 ft) for thick trunk cable.
• The maximum total cable distance at 250 Kbps is 250 m
(820 ft) for thick trunk cable.
• The maximum total cable distance at 500 Kbps is 100 m
(328 ft) for thick trunk cable.
• The maximum length of mixed cables may be found by
solving the following equation:
L
+ 5*L
Thick
L
must not exceed 156 m (511 ft).
Thin
= 500 m (1640 ft).
Thin
The most common power configuration is shown in Figure 4.
The 5-point plug connector should be wired with cable approved
for DeviceNet applications. The colors of the wires should be
matched to the DPONI label.
Figure 4. Typical DeviceNet Power Configuration.
The DeviceNet cable insulation should be stripped back
approximately 1 in. (25.4 mm) from the end. Each of the wires
should be stripped approximately ¼ in. (6.5 mm). The terminals
of the DeviceNet connector should be tightened to 5 to 7 in-lbs
(0.57 to 0.79 N-m). The drop cable can be daisy chained by
terminating two wires under one screw.
Operational Check
After the DeviceNet system has been installed, check the
operation of the DPONI by applying power to the host device and
to the DeviceNet network. When under power from both
sources, the bicolor LED should:
• Turn green for approximately 0.25 second;
• Turn red for approximately 0.25 second; then
• Turn off.
Note that a minimum of two nodes (a master and a slave) must
be under power for the Duplicate MAC ID check to complete
successfully.
The DPONI does not support network-settable addressing. The
DPONI address is entirely switch- dependent. Each DPONI is
shipped with its address switches set to 63.
The DPONI’s bicolor combined network/status LED functions as
defined in the DeviceNet Specification. In brief, after DPONI
initialization, the status LEDs perform as described in the
following section of this instruction leaflet.
LED Definitions and Diagnostics
During the power-up initialization sequence, all three bicolor LEDs
should blink green, then red, then off. This indicates that all three
LEDs are functioning correctly. After initialization, these LEDs
function according to the following descriptions.
Combined Module/Network Status (NS) LED
The Combined Module/Network Status (NS) LED provides an
indication of the status of the DeviceNet Network as listed in
Table 1.

5 WIRE TX
The 5 WIRE TX is a monocolor LED that flashes whenever the
DPONI is receiving communications from the attached host
device.
Troubleshooting
In the unlikely event the LEDs do not function as previously
described, the following items should be checked.
1. If all LEDs remain off, check to make sure that the
DeviceNet terminal plug is connected and that the
DeviceNet network is under power.
2. If the combined Module/Network status LED blinks red
and/or green, check to make sure that all the DeviceNet
devices on the network are communicating at the same rate
(125, 250, or 500 Kbps).
3. If the combined Module/Network status LED blinks green,
then red, and then turns solid red, check to make sure that
there is a master node on the DeviceNet network and that
appropriate application software has been installed and is
functioning correctly on that master node. Then, check to
ensure that this DPONI node has a unique MAC ID.
4. If the 5-WIRE LED remains off, check the function of the
host device on which the DPONI is mounted. If it is
connected, powered, and showing correct readings on the
faceplate, remove the DPONI’s ribbon cable from the unit
and reattach it.
5. Check the DeviceNet network wiring for loose connections,
shorted wires, etc.
6. If suggestions 1 through 5 do not remedy the problem, the
DPONI may need to be replaced.
