Usage Precautions
Operating Environment
• Please use the gateway only when the ambient temperature of the
environment into which the unit is installed is within the following
specified temperature limits:
Operation
Storage
• Avoid installation locations that may be subjected to large shocks or
vibrations.
• Avoid installation locations that may be subjected to rapid changes in
tem
: -10 ∼ +50°C (+14 ∼ +122°F)
: -40 ∼ +85°C (-40 ∼ +185°F)
erature or humidity.
Installation and Wiring
• Proper ground connections are vital for both safety and signal
reliability reasons. Ensure that all electrical equipment is properly
grounded.
• Route all communication cables separate from high-voltage or noise-
emittin
cabling (such as ASD input/output power wiring).
ASD Connections
• Do not touch charged parts of the drive such as the terminal block
while the drive’s CHARGE lamp is lit. A charge will still be present in
the drive’s internal electrolytic capacitors, and therefore touching these
areas may result in an electrical shock. Always turn all drive input
power supplies OFF, and wait at least 5 minutes after the CHARGE
lamp has gone out before connecting communication cables.
• To avoid misoperation, do not connect any gateway terminals to either
the ASD’s E/GND terminals, the motor, or to any other power ground.
• When making common serial connections between the gateway and
ASDs, do not use cables that exceed 5 meters in length.
• For further drive-specific precaution, safety and installation
information, please refer to the appropriate documentation supplied
with your drive.
• Internal ASD EEPROMs have a limited life span of write cycles.
Observe all precautions contained in this manual and your ASD
manual regarding which drive registers safely may and may not be
repetitively written to.
• When used without an auxiliary power source (ASD common serial
mode), the gateway derives its control power from the connected
drives. Therefore, removing power to all connected drives will also
cause the
ateway to lose power.

1. The Network Gateway Series Concept
The DNET-100 is a member of the ICC Network Gateway Series product
family. Members of this family are designed to provide a uniform interface,
configuration and application experience. This commonality reduces the
user’s learning curve, reducing commissioning time while simplifying support.
The heart of the Network Gateway Series concept is an element called the
“point database” (refer to Figure 1). The point database is entirely userconfigurable, and provides the end-to-end mapping information that allows
primary network requests to be routed to the correct locations on the
secondary network, while at the same time ensuring that the content of the
request will be understood once it gets there. Additionally, the point database
provides the added benefit of “data mirroring”, whereby current copies of point
values (secondary network data objects) are maintained locally within the
gateway itself. This greatly reduces the primary network’s request-to-response
latency time, as read and write requests can be entirely serviced locally,
thereby eliminating the time required to execute a secondary network
transaction.
When properly configured, the gateway will become essentially “transparent”
on the networks, and the primary network master can engage in a seamless
dialogue with one or more secondary network devices. This can all be
accomplished without regard to the characteristics (physical layer or protocol)
of the primary or secondary network.

3. Feature Summary
Primary Network
DeviceNet (5-conductor pluggable terminal block style)
Secondary Network
The DNET-100 has two physically independent secondary networks,
depending on the application:
• ASD common serial:
simultaneous connection of three Toshiba 7-series, 9-series or VFnC1 ASDs via the drives’ common serial (aka logic level)
communication ports. ASD connections use the same standard RJ45
style 8-conductor UTP patch cables: any standard CAT5 Ethernet
cable (found in most electronics stores) 5 meters or less in length can
be used to connect the DNET-100 to the drives.
• RS-485:
Power Supply
When connected to ASDs via the ASD 1 / ASD 2 / ASD 3 ports, can be either
powered directly from the attached ASDs, or from the auxiliary “POWER” input
jack. All RS-485 secondary network topologies require the use of the auxiliary
“POWER” input.
Supported Protocols
•

Point File-Based Configuration
Up to 3 point files (primary / secondary network mapping definition files) can be
stored in the unit’s internal battery-backed file system. Point files can also be
uploaded from / downloaded to a PC, which provides the capability for PCbased file backup and easy configuration copying to multiple units. Sample
point files and related documentation can also be downloaded from the ICC
web site, uploaded to a unit, and custom-modified to suit a specific application.
Drive AutoScan Algorithm
ASD common serial port connections are automatically established and
continuously monitored (when points are defined for that drive). No drive
configuration needs to be performed to connect the gateway to the drives.
Just plug it in – it’s that simple.
Network Timeout Action
A configurable network timeout selection can be programmed that allows each
DeviceNet parameter object to have its own unique “fail-safe” condition in the
event of a primary network interruption event.
Indicators
2 green LEDs exist on each of the ASD ports and on the MMI port connector.
The DNET-100 also contains bicolor DeviceNet network status (NS) and
module status (MS) LEDs. Refer to section 9 for more detailed information
about the LED indicators and their meanings.
MMI Port Connector
RS232-level. Use the DB9-to-RJ45 MMI cable supplied with the gateway kit to
interface with the unit for either console-based configuration, point file
upload/download, or flash firmware downloading.
EDS Autogenerator
The DNET-100 automatically generates a customized Electronic Data Sheet
(EDS) once configuration is complete. This EDS is then transmitted to your
computer via the Xmodem protocol for registration by network configuration
tools.
Field-Upgradeable
As new firmware becomes available, the gateway unit can be upgraded in the
field by the end-user. Refer to section 15 for more information.
Versatile 3-Way DIN-Rail Mounting System
The unit’s enclosure is provided with a mounting clip attached to the rear of the
unit. This clip allows the unit to be mounted 3 different ways:
•
For DIN rail mounting, snap the mounting clip onto a standard DIN
rail, and then snap the unit enclosure onto the clip’s retaining tabs.
This allows easy removal or repositioning of the unit on the DIN rail
during wiring.
12
•
For panel mounting, the mounting clip can be bolted directly to a flat
panel via the two bolt holes at the top and bottom of the clip. Refer to
section 2.2 for mounting clip mechanical details. Once the mounting
clip is securely attached to the panel, the unit enclosure can be
snapped onto the clip’s retaining tabs.
•
For fixed DIN rail mounting, a combination of the above two
techniques can be employed. First, snap the mounting clip onto a
DIN rail and position it in its desired location. Then, the mounting clip
can be bolted to the DIN rail support panel, securing it in place.
Lastly, the unit can be snapped onto the fixed mounting clip.
In all cases, the unit can be easily unsnapped from the mounting clip whenever
necessary to provide easier access.

4. Installing the Interface
The installation procedure of the gateway will vary slightly depending on the
chosen secondary network.
4.1 RS-485 Secondary Network
Note that in order to power the unit when using the secondary RS-485 network,
you must also purchase the optional 120VAC/9VDC power supply (ICC part
number 10456).
1. Attach the mounting clip and unit enclosure in your desired manner (refer
to page 12 for more information).
2. Connect the DeviceNet network to the 5-position “Network” terminal block.
Be sure to follow all published guidelines pertaining to DeviceNet network
connections, layout and routing. Ensure that the terminal block is fully
seated into the terminal block header, and route the network cable such
that it is located well away from any electrical noise sources, such as ASD
input power or motor wiring. Also take care to route the cable away from
any sharp edges or positions where it may be pinched.
3. Repeat step 2 above to connect the secondary network to the “Secondary
RS-485” terminal block.
4. Take a moment to verify that the gateway and all network cables have
sufficient clearance from electrical noise sources such as drives, motors,
or power-carrying electrical wiring.
5. Connect the power supply to the gateway’s “Power” jack.
14
4.2 Toshiba ASD (Common Serial) Secondary Network
The gateway connects to each drive via the drive’s common serial (logic level)
communication port, typically located on either the main drive control board
(G7), on the front of the drive enclosure under a small snap-on cover (A7, S9),
on the right-hand side of the drive enclosure under a small snap-on cover (S7),
or on the bottom side of the drive enclosure (VF-nC1). Although in general no
drive parameters need to be configured in order to use the gateway, it is
advantageous to check that the drive’s common serial communication data
rate is set to its maximum speed. Because the gateway will communicate to
each drive only at the drive’s configured data rate, this will provide the fastest
response time for drive-to-gateway data transfers. For information on checking
the drive’s common serial communication data rate, refer to the appropriate
manual supplied with your drive.
Note that the common serial communication parameters of each drive are
handled independently by the gateway, which means that different drive
families may be connected to different channels of the unit in any combination,
and that the drives connected to each channel may simultaneously
communicate to the unit at completely different baud rates, parity settings, etc.
Drives can be connected to the gateway on any ASD channel in any order or
combination. When more than one drive is connected to the unit, or if the
optional auxiliary power supply is used, the gateway will draw its control power
from the source with the highest power supply voltage.
Installation of the gateway should only be performed by a qualified technician
familiar with the maintenance and operation of the connected drives. To install
the gateway, complete the steps outlined in the following sections related to
your specific drive.

4. Remove the drive’s front cover / open the drive’s cabinet door (refer to the
appropriate drive manual for instructions how to do this).
5. The drive’s LCD panel (also called the “Electronic Operator Interface” or
“EOI”) can communicate with the drive via either the RS485/RS232
channel (CNU1/CNU1A) or the common serial channel (CNU2/CNU2A).
Because the gateway uses the common serial channel, the LCD panel
must be configured to use the RS485/RS232 channel. If the drive to be
connected is currently using CNU2 (on the drive control board) and
CNU2A (on the LCD panel), then this connection must first be switched
over to CNU1 (on the drive control board) and CNU1A (on the LCD panel).
Refer to Toshiba’s documentation for any precautions or notices regarding
this connection change. If the LCD panel is already connected via the
RS485/RS232 channel, then no change is required.

7. Connect the drive’s common serial communication port (CNU2) to one of
the ASD channels of the gateway with the communication cable
(communication cable is not included with the gateway kit). When
choosing cables for this connection, standard 24 AWG category 5 (CAT5)
unshielded twisted-pair (UTP) 8-conductor cables found in Ethernet
networks in most office environments can be used. The maximum
allowable length for these cables is 5 meters. Although there are many
varieties and styles of CAT5 UTP cables available, ICC strongly
recommends using only high-quality cables from reputable manufacturers
to guarantee optimal noise immunity and cable longevity. Ensure that
each end of the cable is fully seated into the modular connectors, and
route the cable such that it is located well away from any drive input power
or motor wiring. Also take care to route the cable away from any sharp
edges or positions where it may be pinched.
8. Reinstall the drive’s front cover / close the drive’s cabinet door.
9. Repeat steps 1-8 to connect other drive(s) as needed.
10. Connect the DeviceNet network to the 5-position “Network” terminal block.
Be sure to follow all published guidelines pertaining to DeviceNet network
connections, layout and routing. Ensure that the terminal block is fully
seated into the terminal block header, and route the network cable such
that it is located well away from any electrical noise sources, such as ASD
input power or motor wiring. Also take care to route the cable away from
any sharp edges or positions where it may be pinched.
11. If an auxiliary power supply is going to be used, connect it to the
gateway’s “Power” jack.

5. RS-485 Electrical Interface
In order to ensure appropriate network conditions (signal voltage levels, etc.),
some knowledge of the gateway’s RS-485 network interface circuitry is
required. Refer to Figure 7 for a simplified network schematic of the secondary
RS-485 interface circuitry. Note that the “Shield” terminal has no internal
connection: its purpose is simply to provide a cable shield chaining location
between devices. The shield is then typically connected to ground at one
location only.
