CAUTION
1.
DO NOT INSTALL THE DPONI IN LOCATIONS WHERE THE
TEMPERATURE AT THE UNIT FALLS OUTSIDE THE RANGE OF –
20 C TO 70 C (-4 F TO 158 F). COOLING EQUIPMENT, SUCH AS
A FAN, SHOULD BE USED TO LOWER THE TEMPERATURE IF
THE 70 C (158 F) LIMIT IS EXCEEDED. HEATING EQUIPMENT
SHOULD BE PROVIDED IF THE –20 C (-4 F) LIMIT IS
EXCEEDED.
2.
DO NOT INSTALL THE UNIT WHERE THE RELATIVE HUMIDITY
EXCEEDS 90% OR WHERE CONDENSATION FORMS DUE TO
RAPID TEMPERATURE CHANGES. A HEATER SHOULD BE
PROVIDED TO PREVENT THE FORMATION OF CONDENSATION.
3.
DO NOT INSTALL THE UNIT WHERE DUST, SALT, OR IRON
PARTICLE DENSITIES ARE HIGH.
4.
DO NOT INSTALL THE UNIT WHERE IT MAY BE SUBJECTED TO
DIRECT IMPACT OR VIBRATION.
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
Thick
+ 5*L
Thin
= 500 m (1640 ft).
L
Thin
must not exceed 156 m (511 ft).
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.
