Overview
This chapter contains a short description of the DeviceNet standard and the DNP31 DeviceNet Interface module.
DeviceNet Standard
The DeviceNet network has a linear bus topology. Terminating resistors are required on each end of the trunk line. Drop lines
as long as 6 metres (20 feet) each are permitted, allowing one or more nodes to be attached. DeviceNet allows branching
structures only on drop lines.
The DeviceNet Communication Interface
The DNP31 communication interface is an optional device for the UMC100.3 which enables the connection of the
UMC100.3 to a DeviceNet system. The UMC100.3 is considered as a slave in the DeviceNet network.
• Use UMC100.3 to set bus address and baud rate (or autobaud) of the DeviceNet communication. Once the address
is set, it is stored in the DNP31, even in case of supply voltage breakdown.
Through the DNP31 DeviceNet communication interface it is possible to:
• give control commands to the drive (Start, Stop etc.)
• read status information and actual values from the drive
• read and write UMC100.3 parameter values
• reset a UMC100.3 trip.
The DNP31 acts as a Class 2 only slave with predefined master-slave connection set services. These include the
Explicit Messaging, the Poll-Response service and the Change of State/Cyclic service. The DeviceNet commands and
services supported by the DNP31 DeviceNet communication interface are discussed in chapter Communication.

Mechanical Installation
The DeviceNet adapter module DNP31 can be mounted either on the UMC100.3 itself or separately from the UMC100.3 using
the single mounting kit (SMK3.0).
Mounting the DNP31 on the UMC100.3
When the module is installed directly on the UMC100.3 the UMC100.3 with DNP31 acts like a device with integrated DeviceNet
communication. No additional accessories are needed.

Mounting the DNP31 remotely from the UMC100.3
When the communication interface is installed remotely from the UMC100.3 - e. g. in the cable chamber of a motor control
center - the DNP31 must be separately supplied. This makes it possible to keep the DNP31 online even in the case when the
drawer is removed. Ready made cables are available. But it is also possible to use own cables.
For more details see section „Using DNP31 in a Drawout System“.
Mounting the Single Mounting Kit
The single mounting kit (SMK3.0) can be either mounted on a DIN rail hat or fixed with screws on a fitting panel.
Mounting the DNP31 on the Single Mounting Kit
Step 1:
Plug in the communication
connectors.
Step 3:
Move down the DNP31 until
snapped in
Step 2:
Move down the DNP31

Demounting the DNP31
Follow the shown procedure for demounting the DNP31 from UMC100.3 or SMK.3.
For demounting slightly rotate
screw driver and move the DNP31
upwards to loosen snap-in
connection.

Electrical installation
DeviceNet Connection
Connect DeviceNet to X3.
General cabling instructions
– Arrange the bus cables as far away from the motor cables as possible.
– Avoid parallel runs
– Use bushings at cable entries
Bus termination
Bus termination is required to prevent signal reflections from the bus cable ends. The DNP31 DeviceNet interface module is not
equipped with internal bus termination
The DeviceNet network should be terminated at both ends of the trunk cable with a 121 ohm,
¼ W, 1% Metal Film resistor. Connect this resistor between the two signal wires (CAN_H,
CAN_L) on the DeviceNet cable.
Setting the Communication Parameters
The DeviceNet interface module does not provide means to adjust the DeviceNet slave address and baud rate (incl. autobaud).
The DeviceNet slave address, baud rate and communication timeout can be set in the UMC100.3 and are copied to the
DeviceNet interface module during initial connection between UMC and DNP31. When changing communication parameters later
on perform a power cycle. The baudrate is set to 'autobaud' by default.
Network and Baudrates
The maximum length of trunk cable depends on the data rate and on the type of the cable used.
• DeviceNet Cables: YR-29790 (Thick DeviceNet Cable) or YR-29832 (Thin DeviceNet Cable)
• Maximum Bus Length: 1200 m
• Topology: Multi-drop
• Serial Communication Type: Asynchronous, half Duplex
• Transfer Rate: 125, 250 or 500 kbit/s
