Chapter 1 Summary
EXP-DN-BDI-VDI can connect with DeviceNet by DeviceNet Extended Communication
Module. To DeviceNet, EXP-DN-BDI-VDI DeviceNet Communication Module is a Group2
Only Slave device; it is a slave station of DeviceNet.
To Inverter, EXP-DN-BDI-VDI Communication Module connected with Inverter by RS485
communication port.
DIP switch SW1_8 is required to be set OFF if EXP-DN-BDI-VDI Module is connected
with the inverters of VDI100/BDI50 series.

Chapter 3 Operation
3.1 Initial power up
EXP-DN-BDI-VDI can use net power, if power is lower because many devices in
devicenet system and, it also can use DC power with itself.
Before power up, check that you have connected the power supply, the bus connection
and the connection to the basic unit correctly.
If the EXP-DN-BDI-VDI unit is factory setting, the net address and baud rate of the station
must be set.
3.2 Networking Settings
EXP-DN-BDI-VDI module is built in the function of automatic identification drive. Use DIP
switch SW1_8 (8PIN) to set up. Set SW1_8 to be OFF if it is connected to the inverter of
VDI100/BDI50 series.
3.3 Network Address Settings and Self-adjust Baud Rate
In the net system, each device has one unique node address (MAC ID), user can set
node address form 0 to 63, and each node MAC ID must be unique in the net system.
EXP-DN-BDI-VDI module use SW1.1～SW1.6 to setting node address.
EXP-DN-BDI-VDI communication module supports the self-adjust communication baud
rate, three kinds of 123K, 250K and 500K in compliance with DeviceNet specifications. When
device is at power on, the module is only connected to network and obtains the baud rate
from the detection of network package. After the baud rate is self-adjusted, it is connected to
DeviceNet in normal operating mode.
After powering on the device at the basis of hardware setting address, it is disabled when
baud rate and network bits address are modified by network tool.

Chapter 4 Communication module functions
4.1 Net Description
DeviceNet is a connection based protocol. That is data exchange among devices should
be through connected cable.
Net stations can communication with IO message or explicit message.
4.1.1 IO message
IO message transmits application and process data in DeviceNet. The related IO
message, sent via higher CAN identifier, is always sent from producer to consumer. The
connection identifier provides the related information. The transmission is realized through
the connected object which is setup before message transmitted.
The most important feature of IO message frame is transmission data through CAN data
layer. The nod terminal judges the importance of the proceed data via the CAN message
identifier.
4.1.2 Explicit message
Explicit message is used on ordinary data exchange between two devices in DeviceNet. It
is sent via lower CAN identifier. Explicit message is point and point transmitted with the
typically request/response mode. It is commonly used in equipment configuration and trouble
shooting. The transmission of the explicit message should be through connected objects.
The Explicit message request specifies object, instance, property, and the called classificated
service through the path to the related object.
The most important feature of explicit message is the any parts of CAN identifier can not
be used in explicit message transmission protocol. All the protocol should be included in CAN
data layer which is used in connecting ID. Each Explicit message channel needs 2 CAN
identifier, one is for request message, and the other is for response message. The identifier is
already specified as the connection sets up.
4.1.3 EXP-DN-BDI-VDI deviceNet function
•Support self-adjust baud rate
•Support duplicate nodes and check the packet
•Support predefine master slave connection
•Support predefine explicit message connection
•Support predefine poll IO message connection
•Support explicit and IO message fragment

4.2 EXP-DN-BDI-VDI Object Modeling
DeviceNet describes seeable data and function through the object modules. One
DeviceNet equipment can be defined as a group which is based on a clear device module.
DeviceNet object module describes all the EXP-DN-BDI-VDI communication function
which is the basic principal of the application layer.

All net devices must be support devicenet object (class code: 03hex). It provides the
configuration and status of a DeviceNet port. DeviceNet product must support one (and only
one) DeviceNet object per physical connection to the DeviceNet communication link.
•Connection object class
All net devices must support at least one object instance. It provides operation net data
by IO message or explicit message, producer/consumer data router and length.
4.2.3 Application class
Define the certain data and function of the equipment (application object, parameter
object, and assemble object).
•Application object class
Extend object (class code: 28hex、2Ahex、65hex、66hex) provides the parameters of
