Safety Precautions
!WARNING Never attempt to disassemble any Units while power is being supplied. Doing
so may result in serious electrical shock or electrocution.
!WARNING Make sure that the current or voltage input to the Unit is within the specified
ranges. Using a current or voltage outside of the specified range may result in
damage or fire.
!WARNING Provide safety measures in external circuits (i.e., not in the Programmable
Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the PLC or another external factor
affecting the PLC operation. Not doing so may result in serious accidents.
1. Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
2. The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe failure alarm (FALS) instruction is executed. External safety measures must be provided to ensure safety in the system in
case an error or FALS instruction causes all outputs to be turned OFF.
3. The PLC outputs may remain ON or OFF due to fusing or burning of the
output relay contacts or destruction of the output transistors. External safety measures must be provided to ensure safety in the system in case the
outputs fail and remain ON or OFF.
4. When the 24-V DC output (service power supply to the PLC) is overloaded
or short-circuited, the voltage may drop and result in the outputs being
turned OFF. External safety measures must be provided to ensure safety
in the system in case of a power supply problem that causes outputs to be
turned OFF.
!WARNING The PLC’s CPU Unit continues I/O refreshing even when the program is not
being executed (in PROGRAM mode). Before proceeding with any of the following operations, verify that it is safe to do so in case the operation changes
the status of output bits allocated to Output Units or the data allocated to Special I/O Units or CPU Bus Units. It is possible for a load connected to an Output Unit, Special I/O Unit, or CPU Bus Unit to operate unexpectedly.
• Using a Programming Device (Support Software in a personal computer)
to transfer data to the CPU Unit’s I/O memory area.
• Using a Programming Device to change present values
• Using a Programming Device to force-set or force-reset bits
• Transferring an I/O memory file to the CPU Unit from EM file memory

DeviceNet Network Features
DeviceNet is an open field network that can easily connect a variety of control
devices such as PLCs, personal computers, sensors, and actuators.
The DeviceNet network not only reduces wiring and maintenance costs
because it requires less wiring, it also allows DeviceNet-compatible devices
from different manufacturers to be connected. There is a wide selection of
DeviceNet-compatible devices available, so a more economical system can
be constructed.
1-1-1
Reduced Wiring
Use DeviceNet cables to wire connections such as multi-drop trunk lines and
T-branch lines. These connection methods can help reduce onsite wiring
costs and maintenance costs.

Multi-vendor Networks
The DeviceNet communications specifications are open and standardized, so
a DeviceNet-compatible device from any manufacturer can be connected.
DeviceNet can be used in a variety of field-level applications by combining
devices such as valves and sensors.

There are two kinds of nodes in a DeviceNet Network: Slaves and Masters.
The Slaves connect to external I/O and the Masters manage the Network and
the external I/O of the Slaves.
Note The Master and Slaves can be connected at any location in the Network, as
shown in the preceding diagram.
Trunk/Branch Lines
Terminator
The trunk line refers to the cable that has Terminating Resistors on both ends.
Terminator
23
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
Section 2-1
Network Configuration Overview
The cables branching from the trunk line are known as branch lines.
Terminator
Terminator
T-branch Taps
All are branch lines.
There is no limit on the number of T-branch Taps.
Only the total length of the branch lines is limited.
DeviceNet cables (Special Thin/Thick Cables and Special Flat Cables) are
used for both the trunk and branch lines in DeviceNet communications. Special Thin/Thick Cables include Special Thin Cables and Special Thick Cables.
Note With Environment-resistive Slaves (Slaves with a round connector), special
OMRON cable with a shielded, waterproof connector is used for both the
trunk and branch lines.
Terminating Resistors
(Terminators)
Always connect Terminating Resistors at both ends of the network to reduce
signal reflection and stabilize communications. The cable that stretches from
one terminator to the other is the trunk line. Determine which cable will be the
trunk line based on the network’s configuration.
Trunk
line
Trunk line
There are two main kinds of Terminating Resistors available, one for the Tbranch Tap/Power Supply Tap and one for a Terminal Block. There are also
connectors with terminating resistance (male and female) that connect to the
Shielded T-branch Connector used with Environment-resistive Slaves.
Note When using a Terminal-block type Terminating Resistor, a DeviceNet cable
must be used for the cable connecting the Terminating Resistor.
Connection Methods
Two methods can be used to connect DeviceNet nodes: The T-branch method
and the multi-drop method. With the T-branch method, the node is connected
to a branch line created with a T-branch Tap or Shielded T-branch Connector.

Current Capacities of
the Cables
The current capacity of the trunk line is 8 A when a Thick Cable is used, 3 A
when a Thin Cable is used, and 5 A when a Special Flat Cable is used. To
estimate the current through the trunk line, add up the current consumption of
all the nodes in each direction from the communications power supply. The
total current consumption must be no more than 8 A when a Thick Cable is
used, 3 A when a Thin Cable is used, and 5 A when a Special Flat Cable is
used.
With branch lines, the current carrying capacity of the branch line is inversely
proportional to the length of the line. The current capacity of a branch line is
4.57/L (A) where L is the length of the branch line (m). Verify that the total cur-
27

Section 2-1

rent consumption of the nodes in the branch is less than 4.57/L or 3 A, whichever is lower.
Refer to SECTION 3 Communications Power Supply Methods for more
details.
Note
1. Always use DeviceNet cables.
2. Always connect terminators at both ends of the trunk line.
3. Do not install devices other than DeviceNet devices (e.g., a lightning arrestor) in the communications line. Devices other than DeviceNet-compatible
devices can cause effects such as signal reflection and interfere with DeviceNet communications.

Trunk Lines and Branch Lines
Description of Trunk and
Branch Lines
The DeviceNet network is made up of a trunk line and branch lines. The trunk
line is the main line in the network and it is terminated at both ends by Terminating Resistors.
Thick, thin, and flat cable can be used for both trunk and branch lines.
Cable type
Advantages
Disadvantages
Thick cable • Can be used for long distances. • Stiff and difficult to bend
• Higher current capacity (8 A)
Thin cable • Flexible (Can be used in tight
• Lower current capacity (3 A)
spaces.)
• Not suitable for long distances
Flat cable
• Branching and extending
cables is simpler.
• The maximum network length and
current capacity are somewhere
between those of Thick and Thin
Cable.
There is no limit on the number of nodes that can be connected on a branch
line, although the total number of node in the network is limited. Also, there is
no limit on the number of sub-branches that can be drawn from a branch line.
These features allow branches to extend from the trunk line like the branches
of a tree, although the length of branches and total branch line length cannot
be too long.
Branch Line Length
Branch lines can be up to 6 m long.
The branch line length is the distance from the point in the trunk line where
the original branch was made to the end of the branch. (The branch line
length is not just the distance between T-branch Taps or the distance from a Tbranch Tap on the branch line to a node; it is the total distance from the trunk
line to the end of the branch.)
The branch line length is limited to 6 m in all cases.

Even if all branch lines are less than 6 m, the network will not operate properly

remote I/O communications errors and transmission timeouts.
Total Branch Line Length
The total branch line length is the sum of the lengths of all branch lines in the
network. The maximum total branch line length depends upon the baud rate,
as shown in the following table.

Maximum Current Capacity
The maximum current capacity of a line depends on the cable type and the
function of the line (trunk or branch line). When planning the network configuration, consider the type of cable being used, position of each device, and
each device’s current consumption.

It can be time-consuming to calculate the total branch line length and fairly difficult to meet the conditions that individual branch lines do not exceed 6 m
and the total branch line length does not exceed 39 m (with a baud rate of
500 kbps.) A common cause of long branch lines and excessive total branch
line length is using a straight trunk line, as shown in the following diagram.

The branch line lengths can be reduced significantly by redirecting the trunk

The branch line length and total branch line length limitations are the same for
both thin and thick cables. The cables differ in the following two capabilities.
1. Maximum network length
With thin cable, the maximum network length is limited to 100 m in all cases. At 500 kbps, the maximum network length is the same for both thick
and thin cables, so this limitation is not a consideration when the baud rate
is 500 kbps.
Thick and thin cable can be used in the same network, but the max. network length declines as more thin cable is used. Refer to Combining Thick
and Thin Cables on page 37 for the equations used to calculate the max.
network length when thick and thin cable are used together.
2. Current capacity
In the trunk line, the cable current capacity (max. current allowed in the cable) is 3 A for thin cable and 8 A for thick cable. Consequently, thick cable
can provide a significantly higher current when the communications power
supply is being supplied through a Power Supply Tap. If thin cable is being
used, the current in any one direction is limited to 3 A regardless of the capacity of the 24 V DC power supply that is connected.

Note The communications power supply can also be supplied through a T-branch
Tap or T-branch Connector, but the current capacity of a T-branch Tap is 5 A.
The current capacity of the thin-cable T-branch Connectors is 3 A and the current capacity of the thick-cable T-branch Connector is 8 A. Consequently, the
conditions for supplying power through a T-branch Tap or thin-cable T-branch
Connector are as follows: There can be only one communications power supply in the network and the total current consumption (in both directions) is limited to 5 A for a T-branch Tap or 3 A for a thin-cable T-branch Connector.
Combining Thick and Thin
Cables
Thick and thin cable can be combined in the line connecting most distant
nodes, but the max. network length will be shorter than it would be with thick

The results of the above formulae indicate that 250 kbps and 125 kbps can be
used as the baud rates for this configuration example.
Even when the above conditions are met, however, the current flowing
through the cables must not exceed the permissible current capacity. (Refer to
SECTION 3 Communications Power Supply Methods.)

Thin cable must be used in applications where space is restricted and thick
cable cannot be bent enough. In particular, use thin cable when wiring
devices mounted to DIN Track and the area between the DIN Tracks is limited.

Proper Distance between
Wiring Duct and Node
Allow about 10 cm between the wiring duct and nodes so that the nodes can
be wired without straining the connectors. Communications errors may occur
if there isn’t enough slack in the cable and the connectors are pulled out.

Note Do not strip too much insulation and shielding from the cable. Removing too
much shielding will provide a path for noise to enter the network.
Considerations in
Choosing Special Thin/
Thick Cable or Special Flat
Cable
Using Special Flat Cable makes it easy to extend a branch cable using onetouch connectors, but Special Flat Cable cannot be combined with a trunk line
consisting of Special Thin/Thick Cable. There are differences between Special Thin/Thick Cable and Special Flat Cable in terms of maximum network
length, branch line length, and current capacity. For detailed specifications,
refer to 2-2-2 Trunk Lines and Branch Lines.

Determining the Location of the Master
It is not necessary to locate the Master at the end of the network. The Master
can be located at any node position on the trunk line or a branch line.
Configure the network as desired, since there is no restriction on the Master’s
location.

T-branch Tap Connections
The single-branch T-branch Taps (3 connectors) can be used to make a
branch from the trunk line or a branch line. It isn’t necessary to connect the
paired connectors to the trunk line. Likewise, there is no restriction on the use
of connectors in a three-branch T-branch Tap. The connectors can connect to
the trunk line or branch lines.

2-2-6
Connecting Devices other than DeviceNet Products
Do not connect devices that are not DeviceNet products because incompatible devices can cause signal reflection or attenuation and interfere with normal network communications.
2-2-7
Connecting Terminators (Terminating Resistors)
What is a Terminating
Resistor?
A Terminating Resistor (commonly known as a terminator) is a resistor connected to the end of the trunk line to absorb the signals sent through the network, dissipating the signals as heat and preventing them from bouncing back
into the network. A Terminating Resistor is required at each end of the network (trunk line).
Note Terminating resistors are not built into DeviceNet devices.
Operation without
Terminating Resistors
The DeviceNet network will not function properly without Terminating Resistors. Communications errors will occur, such as remote I/O communications
errors and communications timeouts.
The signals in a DeviceNet network are comparable to surface waves on
water. When a stone is dropped in a bucket of water, circular waves emanate from the stone and run into the sides of the bucket and the reflected
waves interfere with the waves coming from the center. As a result, the
waves from the center become distorted.
The same principle applies to the digital signals in a DeviceNet network.
When the digital signals (waves) passing through the network reach the
end of the network, the bounce back and interfere with the signals (waves)
emanating from the DeviceNet Master (center) of the network.
The Terminating Resistors absorb the digital signals at the ends of the network so that they do not bounce back and distort the signals from the Master.
Operation with Too Many
Terminating Resistors
If Terminating Resistors are attached at all T-branch Taps within the network,
the digital communications signals will be absorbed midway through the network and the network will not function normally. Communications errors will
occur, such as remote I/O communications errors and communications timeouts.

Network Configuration
Section 2-2
Checking the Installation
of Terminating Resistors
If communications errors occur when setting up the system, it is possible to
check whether or not the Terminating Resistors are connected properly. Turn
OFF the network power supply and use a multimeter to test the resistance
between any node’s CAN H signal wire (white) and CAN L signal wire (blue).
• A normal resistance reading is 50 to 70 Ω.
• If the resistance is greater than 70 Ω, there may be a broken signal line
in the network or one or both Terminating Resistors may be missing.
A reading of about 100 Ω indicates that one Terminating Resistor is
missing.
A reading of about 300 Ω or higher indicates that both Terminating Resistors are missing.
• If the resistance is less than 50 Ω, there may be too many Terminating
Resistors (3 or more) in the network.
Multimeter
Use a multimeter to
measure the resistance
between the signal wires.
Ω
White (CAN H)
Blue (CAN L)
Note Do not test the resistance while the network is operating. Errors will occur in
the communications data and could cause unexpected problems.
2-2-8
Using Crimp Terminals
We strongly recommend the use of crimp terminals (solderless pin terminals)
on the wires that connect to the communications cable connectors. The following problems may occur if crimp terminals are not used.
1. A stray wire strand may contact the adjacent terminal and cause a short.
2. The cable may pull out of the connector.
3. The contact between the wire and connector may be poor.
Refer to 2-4 Wiring Methods for information on recommended crimp terminals.
2-2-9
Sharing the Communications and Internal Circuit Power Supply
To avoid noise problems, it is generally recommended to provide separate
communications and internal circuit power supplies, but the same power supply can be used for both purposes if necessary.
When a power supply is shared for the communications and internal circuit
power supplies, wire the network as shown in configuration A. Do not use configuration B because it will generate more noise than configuration A.

2-2-10 Grounding Methods
Ground the DeviceNet shield wire to 100 Ω max. at one and only one point in
the network. Grounding more than one point can cause ground loops and
noise in the network.
Proper Grounding
Practices
Generally, the communications power supply’s FG terminal is grounded to
100 Ω max. and connected to the V- terminal and the Power Supply Tap’s
shield (S) terminal, as shown in example A below. It is also acceptable to connect the communications power supply’s FG terminal and the V- terminal and
ground the network from the Power Supply Tap’s shield (S) terminal, as shown
in example B below.
In either case, ground the network as close to the center of the network as
possible.

Cables, Connectors, and Related Devices
just that power supply’s to the shield wire and ground it. Do not connect the
shield wire at any other point.
Note
1. Do not ground the shield wire at more than one point in the network.
Ground the network at one point and one point only.
2. Always use a separate ground. Never use the same ground that is used for
inverters or other drive system devices.
3. If a good ground of 100 Ω or less is not available, do not connect the communication power supply’s FG and V- terminals because the ground may
introduce noise into the network.
Minimizing Effects of a
Noisy Ground
When the ground is identified as a source of noise in the network, disconnect
the DeviceNet shield wire to isolate it from the ground. If this step does not
stop noise from entering the network, do not ground the communications
power supply’s FG terminal.
2-2-11 Allocating Node Numbers
Node numbers do not have to reflect the physical position of the nodes in the
network. It is possible to allocate node numbers randomly. It is also acceptable to skip node numbers. While node numbers can be allocated randomly,
we recommend following a pattern when allocating node numbers. For example, set the Master as node 63, the Slaves as nodes 1 through 62, and the
Configurator as node 0.

Communications Cables
In a DeviceNet system, use DeviceNet cables that conforms to DeviceNet
specifications. The cable characteristics affect DeviceNet communications, so
cable that is not within DeviceNet specifications cannot be used. Always use
the specified DeviceNet cables.
There are two kinds of Special Thin/Thick Cable: Thick Cable and Thin Cable.
Thin Cable is used for the cables with attached shielded connectors.

Multi-drop Wiring
Always use a multi-drop connector when making a multi-drop connection with
thick cable. When thin cable is being used, the multi-drop connection can be
made with either a multi-drop connector or a standard rectangular connector.
Refer to Multi-drop Wiring Methods on page 65 for details on proper multidrop wiring methods.

T-branch Taps
Use a T-branch Tap when a T-branch is required in the Network. There are two
kinds of T-branch Taps, one that makes a single branch and another that
makes three branches. There are variations of the single-branch and threebranch Taps that provide different wiring directions and connector insertion
directions.
Note
1. A T-branch Tap cannot be used to create a T-branch in a Network that has
cables with shielded connectors. In this case, a T-branch Connector must
be used. Refer to 2-3-5 Shielded T-branch Connectors for details.
2. Because the T-branch Tap has a Terminating Resistor socket, a Terminating Resistor can be connected to the trunk line by installing one of the resistors provided.
3. When the Network is powered by a single power supply and the total current consumption is 5 A or less, a T-branch Tap can be used instead of a
Power Supply Tap to connect the communications power supply.
4. The T-branch Taps are identical in models DCN1-2C, DCN1-2R, DCN14C, and DCN1-4R; just the connectors included with the Tap are different.

Power Supply Tap
In the DeviceNet system, a 24-V DC communications power supply must be
supplied to the Network. The communications power supply can be supplied
to the cable by connecting it to a Power Supply Tap. Use a regular node connector to connect communications cable to the Power Supply Tap, the same
way that communications cables are connected to a T-branch Tap.
Note
1. If there is just one power supply to the Network and the total current consumption is less than 5 A, the communications power supply can be connected through a regular T-branch Tap instead of a Power Supply Tap.
A Power Supply Tap must be used if there is more than one power supply
connected to the Network or the total current consumption exceeds 5 A.
2. When the Power Supply Tap is connected to thin cable, the current capacity is limited to 3 A through any one of the thin cables. If two thin cables are
connected, 3 A can be supplied to each cable for a total of 6 A.

Terminating Resistors
In a DeviceNet Network, one Terminating Resistor must be connected to each
end of the trunk line. If a Unit is at the end of the trunk line, connect one of the
Terminating Resistors listed in the following table because the Units do not
have built-in terminators.
There are several ways to connect a Terminating Resistor. A special Terminalblock Terminating Resistor can be connected, a resistor can be installed in the
Terminating Resistor socket of a T-branch Tap or Power Supply Tap, or a
shielded connector with terminating resistance can be connected to a Tbranch Connector. A Terminating Resistor is provided with T-branch Taps and
Power Supply Taps. If a resistor is to be installed on a T-branch Tap or Power
Supply Tap, always use the provided Terminating Resistor.

Use the following procedure to prepare and connect the communications
cables to the connectors.
1. Strip about 30 mm of the cable sheathing, being careful not to damage the
woven shield just below the sheathing. Do not remove more than about
30 mm; removing too much of the covering can result in short circuits or
allow noise into the Network.
Approx. 30 mm
2. Carefully peel back the woven shield. There is a bare shield wire under the
woven shield as well as the signal lines and power lines. (The shield wire
will be loose on the outside of the other lines, but it is stiffer than the woven
shield and easy to identify by touch.)
Shield wire
3. Cut away the exposed woven shield, remove the aluminum tape from the
signal and power lines, and strip the sheath from the signal and power lines
to the proper length for the crimp terminal connectors. Twist together the
stranded wires of each signal and power lines.
Strip proper length for
the terminals being used.

In some cases, the Multi-drop Connector cannot be used because there is not
enough space and other Units or connectors get in the way. Refer to Multidrop Connectors on page 51 for a list of compatible Units.
Note
1. Before connecting the communications cables, turn OFF the power supplies to the PLC and all Slaves, as well as the communications power supplies.
2. Use crimp terminals for wiring. Connecting bare twisted wires can cause
the cables to come OFF, break, or short circuit and result in incorrect operation and possibly damage to the Units.
3. Use the proper crimping tool and crimping methods when attaching crimp
terminals. Consult the manufacturer of the tools and terminals you are using. Inappropriate tools or methods can result in broken wires.
4. Be extremely careful to wire all signal lines, power lines, and shielding wire
correctly.
5. Tighten all set screws firmly. Tighten signal lines, power lines, and shielding wire to a torque of 0.5 to 0.6 N⋅m. Tighten connector screws to a torque
of 0.4 to 0.5 N⋅m.
6. Wire the signal lines, power lines, and shielding wire so that they do not

Attaching Shielded Connectors
Use the following procedure to attach shielded connectors to the communications cables. This section explains the basic attachment procedure. For more
details on connector assembly methods, refer to XS2 in the Sensor I/O Connectors Catalog (G05) (The connectors used for DeviceNet communications
cables use screws to secure the wires.)
1,2,3...
1. Insert the cable into the cap, cable clamp, water-tight bushing, and cover.
2. Prepare the communications cable, referring to the procedure described
under Attaching Communications Cables in 2-4-1 Wiring and Installing
Standard Connectors.
3. When using shielded connectors, remove approximately 20 mm of the cable covering, and strip approximately 8 mm of the sheath from the signal
lines and power lines (refer to the following diagram). Do not remove too
much of the covering. Removing excessive cable covering may result in a
short circuit or the expected water-tight capabilities will not be provided.
4. Insert the signal lines, power lines and shield wire into the contact block
holes, making sure the terminal numbers are correct.
5. Tighten the contact block’s line set screws on each of the lines. Tighten the
set screws to a torque of between 0.15 and 0.2 N⋅m using a special screwdriver.
Note Use the OMRON XW4Z-00B Screwdriver to tighten the line set screws of the
shielded connector for custom cable assembly.

Insert the connector fully and tighten the connector by hand. Tighten Microsize Connectors to a torque of between 0.39 and 0.49 N⋅m. Tighten Mini-size
Connectors to a torque of between 0.7 and 0.8 N⋅m.
Note
(1) Tighten the connector ring securely by hand. If the connector is not tightened sufficiently, it will not provide the specified level of environmental resistance and might become loose due to vibration.
Do not use a tool such as pliers to tighten the connector, because the tool
can damage the connector.
(2) To avoid damaging the cable or breaking wires, leave some slack in the
cable so that it won’t be pulled too hard or bent too sharply when connecting. Also, never put heavy objects on top of the cable.

Precautions to Prevent Noise
• To prevent inductive noise, separate the communications lines, PLC
power supply lines, and other power lines. In particular, be sure to keep
the power lines for inverters, motors, regulators, and contactors at least
300 mm away from both the communications lines and the power supply
lines. Also, provide separate conduits or ducts for the communications
lines and power lines.

(100 Ω max.)
• Make the power supply lines to the control panel as short as possible, use
heavy-gauge wire, and ground the power supply properly (100 Ω max.)
• Avoid installing any DeviceNet devices in a control panel that contains
high-voltage devices.
• Install surge suppressors on devices that generate noise, particularly
devices that have an inductive component such as motors, transformers,
solenoids, and magnetic coils.

• Since noise currents often flow through metallic equipment (such as casings), the communications cables should be placed as far away from
metallic equipment as possible.
• Ground the communications cable to 100 Ω max. with a ground wire that
is as short as possible.
• Ground the shielding wire on the communications cable at one point. If
the same ground is used for the communications cable and communications power supply, there is a possibility that noise may be transmitted
through the ground line to the communications line. In order to avoid this,
be sure that the power line ground and the grounds for the communications cables and the communications power supply are located as far
from each other as possible.
• Insert a line filter on the primary side of the communications power supply.
• When there are two or more communications power supplies, ground the
shielding wire at the Power Supply Tap near the center of the communications cable. Do not ground the shielding wire at more than one place.

Considerations when
Using Flat Cable
2-5-2
To prevent unstable operation due to interference when using flat cable in multiple DeviceNet systems, keep each flat cable at least 5 mm apart from any
other flat cable.
Correcting Malfunctions due to Noise
When noise is thought to be the cause of a malfunction in the DeviceNet network, the following countermeasures may be effective.
Problems with the
Communications
Cable Shielding
Isolate the communications cable shielding wire by disconnecting it from the
ground.
Problems with the
Communications
Power Supply
Isolate the communications power supply.
Disconnecting the ground will reduce the noise transferred from the ground to
the communications cable. This countermeasure also reduces the noise current that flows in the shield wire.
This countermeasure reduces the noise transferred from the communications
power supply ground to the communications cable and the noise current that
flows in the communications cable. A switching power supply is usually connected to the case with capacitors as shown below, so the power supply itself
must be insulated from the control board as well as being disconnected from
the FG terminal.

Basic Concepts
• The communications power supply must be 24 V DC.
• Always supply the power from the trunk line.
• When providing power to several nodes from one power supply, try to
locate the power supply near the center of the nodes.
• Provide power through Power Supply Taps. It is possible to use a Tbranch Tap or T-branch Connector instead of a Power Supply Tap when
there is one communications power supply in the system and the current
consumption is within the specifications of the T-branch Tap or T-branch
Connector. Refer to 2-3-4 T-branch Taps or 2-3-5 Shielded T-branch Connectors for details on the current limitations of these components.
• The power supply capacity for cables is restricted to 8 A for Thick Cables,
3 A for Thin Cables, and 5 A for Flat Cables.
• Environment-resistive Slaves are wired with Thin Cable, so the current
through a cable to an Environment-resistive Slave is limited to 3 A.
• A single network is usually supplied by one power supply, however, it is
possible to have more than one power supply when power supply requirements cannot be met with a single power supply. (See 3-6 Step 3: Splitting the System into Multiple Power Supplies.)
• Provide some extra power supply capacity in the network to allow for
future expansion and extend the life of the power supply.
• Turning OFF the communications power supply during operation can
cause errors in the other nodes if the other power supplies are left ON.
• The current capacity of a branch line ranges from 0.75 to 3 A, depending
on its length. Use the following equation to calculate the current capacity.
(The maximum current capacity of a branch line is 3 A, even if the branch
line is shorter than 1.53 m.)
I = 4.57/L
I: Permissible current (A)
L: Length of the branch line (m)

Section 3-3
Locating the Power Supply
Note If the current carried by a thick cable exceeds 8 A even after the power supply
configuration has been changed, the power supply requirements cannot be
met with a single power supply and multiple power supplies must be used.
In configuration 1, the power can be supplied to the trunk line in both directions as long as the current in each direction is 8 A or less when using thick
cable. Consequently, it is possible to have a configuration with a total current
consumption up to 16 A. Change to thick cable if thin cable is being used in
the trunk line and the current through the thin cable exceeds 3 A.
3-3-2
Main Factors for Determining the Power Supply Location
Determine whether or not the current can be supplied normally by finding the
current capacity required by each node and the voltage drop in the cables to
be used to provide power. Calculate the values below in advance.
• The current required by each node
• The distance between the power supply and each node
3-3-3
Calculating the Power Supply Location
There are two methods to find the best location of the communications power
supply on the trunk line.
1. Simple estimation from a graph
2. Calculation by formula (Calculate the voltage drop based on the current requirements of the nodes and the communications cable resistance.)
Each branch line must satisfy the equation on page 88, which shows the
maximum current capacity of a branch line based on its length.
• The graph estimation assumes the worst case scenario from the
standpoint of the power supply (the configuration that has the maximum voltage drop as shown in the diagram below), so any actual power supply configuration will be acceptable based on the graph
estimation.
Node

Node

• Since the graph estimation assumes the worst case scenario, an actual network configuration may be acceptable even if the configuration is
disallowed in the graph. Evaluate the configuration accurately by the
performing the calculations described in 3-5 Step 2: Evaluating the
Configuration with Calculations.
Note When a single power supply is used to provide the communications power
supply and the internal circuit supply, use the formula method to evaluate a
hypothetical power supply location because it cannot be evaluated with the
graphs. Refer to Shared Communications and Internal Circuit Power Supply
on page 97 for details on this calculation.

Step 1: Evaluating the Configuration with Graphs
There is a voltage drop in a communications cable as current flows through
the cable. The voltage drop increases in proportion to the length of the communications cable and the amperage of the current being carried.
The communications power supply at each node must be 11 V DC min. The
following graph shows the maximum current that can be supplied through various lengths of cable while maintaining the minimum voltage required at the
nodes. (The values in the graph provide some extra margin.)

Simple Evaluation of Power Supply Location from a Graph
Check items 1 to 3 listed below for all of the nodes located in the same direction from the power supply. (If power is supplied in two directions, check these
3 items for all of the nodes in each direction.)
1,2,3...
1. Calculate the total current consumption (IA) of all the nodes to which communications power is to be supplied in one direction.
2. Refer to the graph to find the maximum current flow (IB) allowed in the cable based on the type of cable being used (thick or thin) and the distance
from the power supply to the end of the trunk line.
3. Compare the values (IA and IB) found in steps 1 and 2 above. If IA ≤ IB, the
power supply specifications are met and power can be supplied properly
to all nodes.
Note
3-4-2
Be sure to refer to the correct graph because the maximum current
flow is different for thick and thin cables.
Modifying the Configuration
If the graph indicates that power cannot be supplied properly in one direction
(IA > IB), use the following procedure to modify the communications power
supply configuration.
• Move the communications power supply towards the center of the network so that there are nodes to both sides of it.
• If there are already nodes on both sides of the power supply, move the
power supply in the direction that requires the higher current.
• If thin cable is being used, replace it with thick cable.
If power still cannot be supplied properly in one direction (IA > IB) after making
the changes listed above, proceed to Step 2 and calculate the actual current
requirements based on each node’s position in the network and its current
consumption.

Step 1: Evaluating the Configuration with Graphs
Example 1:
Power Supply at the
End of the Network
In this example, the power supply is at one end of a Network with a total
length of 200 m of thick cable. The power supply is located on the end of the
Network. The current consumption of the individual nodes is as follows:

Total power supply length = 200 m
Total current consumption = 0.1 + 0.15 + 0.05 + 0.25 + 0.1 = 0.65 A
Maximum current for 200 m (see table for thick cable) = 1.53 A
Because the total current consumption (0.65 A) is less than the maximum current (1.53 A), the power supply can be placed at the end of the network and
supply current to all nodes.
Example 2:
Power Supply in the
Center of the Network
In this example, the power supply is in the center of a Network with a total
length of 240 m of thick cable. Because the power supply is in the center, the
maximum permissible current can flow both to the left and right, so the power
supply can supply twice as much current as it could when placed at the end of
the network. The current consumption for individual nodes is as follows:

Total current consumption on right: 0.15 + 0.25 + 0.15 = 0.55 A
Maximum current on the left side (see table for thick cable) = approx. 2.5 A
Maximum current on the right side (see table for thick cable) = approx. 2.5 A
(using linear approximation between 100 to 150 m)
Because the total current flow (0.55 A) is less than the maximum current
(approx. 2.5 A) on both the left and the right sides, the power supply can be
placed at the center of the network and provide power to all nodes.
Example 3:
Uneven Power Supply
Distribution
In this example, the power supply is initially located in the center of a Network
with a total length of 240 m of thick cable. The power supply is moved to one
side because the current consumption is significantly higher on that side and
the current flow to that side would be insufficient if the power supply were con-

Total current consumption on left: 1.1 + 1.25 + 0.5 = 2.85 A
Total current consumption on right: 0.25 + 0.25 + 0.85 = 1.35 A
Maximum current on the left side (see table for thick cable) = approx. 2.5 A
Maximum current on the left side (see table for thick cable) = approx. 2.5 A
(using straight line approximation between 100 to 150 m)
Because the total current flow on the left side (2.85 A) is greater than the maximum current allowed on the left side (2.56 A), the power supply cannot supply current to all nodes properly when it is placed at the center of the network.
This problem can be corrected by moving the communications power supply

Maximum current for 100 m on the left (see table for thick cable) = 2.93 A
Maximum current for 140 m on the right (see table for thick cable) = 2.1 A
(using straight line approximation between 100 to 150 m)
Because the total current flow on both the left and right sides is now less than
the allowed maximum current, the power supply can be placed as shown in
the diagram and supply current properly to all nodes.

Section 3-5
Step 2: Evaluating the Configuration with Calculations
3-5
Step 2: Evaluating the Configuration with Calculations
Proceed with this step if the best location for the power supply cannot be
determined from the graphs. Unlike the graph method used in step 1, the calculation method described in this section does not assume a worst-case
power supply configuration.
In DeviceNet, the maximum permissible voltage drop in one power supply line
(+V or −V) is specified as 5 V based on the specified communications power
supply voltage (24 V DC) and the input voltage of the communications power
supply at each device (11 to 25 V DC). The evaluation in this step is based on
the maximum 5 V voltage drop.
The maximum permissible voltage drop in the whole line is 5 V, with the maximum permissible voltage drop in the trunk line specified as 4.65 V and the
maximum voltage drop in a branch line specified as 0.35 V.
Understanding the Voltage Drop
The following diagram shows the voltage drop effect due to the cable. In the
DeviceNet network, the voltage drop over a communications cable is 5 V or
less (allowing some extra margin), based on the specifications for the
communications power supply device (24 V DC) and communications power
supply at each node (11 to 25 V DC).
Voltage drop of VA in the V+ line
V1
Voltage output at the
communications
power supply device.
V2
Voltage supplied
at each node.
Voltage drop of VB in the V− line
V1: Voltage supplied at the communications power supply device. Allow for
ambient variations of the power supply voltage and take V1 to be 23 V.
V2: Voltage supplied at each node. Allow an extra margin and take V2 to be
13 V or greater.
VA: Voltage drop at the power supply cable (+V).
VB: Voltage drop at the power supply cable (−V).
In the DeviceNet network, VA ≤ 5 V and VB ≤ 5 V.
The voltage drop in the communications cables is specified as 5 V for a single
power supply line (+V or −V). Of the permissible maximum voltage drop within
the system (5 V), the permissible voltage drop in the trunk line is 4.65 V and
the permissible voltage drop in a branch line is 0.35 V.
Note The explanation above is for the communications power supply only. When a
single power supply must be used to supply both the communications power
supply and the internal circuit power supply, the maximum voltage drop for a
single power supply line (+V or −V) is just 1 V because the specifications for
the internal circuit power supply are much stricter.
Of the permissible maximum voltage drop for a single power supply line (1 V),
the permissible voltage drop in the trunk line is 0.65 V and the permissible
voltage drop in a branch line is 0.35 V. (Refer to page 97 for details.)

3-5-1
Section 3-5
Formulae for Calculating the Voltage Drop
Independent Communications and Internal Circuit Power Supplies
Determine the distance between the power supply and each node, and each
node's current consumption for communications. (Refer to the table showing
current consumption for various devices in Appendix C Current Consumption
of DeviceNet Devices.) Evaluate whether the configuration satisfies the formula below. If the voltage drop is within the maximum value indicated, power
can be supplied to the nodes properly with the configuration. Of course the
current cannot exceed the maximum current capacity of the cable (8 A for
thick cable and 3 A for thin cable.)
Formula 1: Calculating the Voltage Drop in the Trunk Line
Σ (Ln × Rc + Nt × 0.005) × In ≤ 4.65 V
Ln: The distance between the power supply and node n (not including the
length of the branch line)
Rc: Maximum cable resistance
(Thick cable: 0.015 Ω/m, thin cable: 0.069 Ω/m])
Nt: The number of Taps between node n and the power supply
(0.005 Ω = The contact resistance of a Tap)
In: The communications current required by node n
Shared Communications and Internal Circuit Power Supply
Note We recommend using separate power supplies for the communications power
and the internal circuit power. (For details, refer to 2-2-9 Sharing the Communications and Internal Circuit Power Supply.)
The allowed voltage ranges for the communications power supply and internal
circuit power supply are significantly different, as shown below.
Communications power supply voltage range: 11 to 25 V DC
Internal circuit power supply voltage range: 24 V DC +10% to −15%
The lowest permissible voltage is 11 V DC for the communications power supply, whereas it is 21 V DC (including the extra margin) for the internal circuit
power supply. If the internal circuit power is supplied by the communications
power supply, the maximum permissible voltage drop due to cable resistance
is much lower than it would be if the power supplies were separate.
When the output voltage fluctuation of the communications power supply is
taken into account and 23 V (the lower end of the fluctuation range) is used as
the power supply output voltage, the maximum permissible voltage drop in a
single power supply line is (23 V − 21 V) /2 = 1 V. The permissible voltage
drop can be subdivided into the max. permissible voltage drop in the trunk line
of 0.65 V and the max. permissible voltage drop in a branch line of 0.35 V.
Determine the distance between the power supply and each node, and the
total current consumption (communications and internal circuit power) for
each node. There’s no need to take into account the internal power supply
current consumption of the Master Unit. (Refer to the table showing current
consumption for various devices in Appendix C Current Consumption of
DeviceNet Devices.)
Evaluate whether the power supply configuration satisfies the formula below.
If the voltage drop is within the maximum value indicated, power can be supplied to the nodes properly with the configuration. Of course the current cannot exceed the maximum current capacity of the cable (8 A for thick cable and
3 A for thin cable.)

Modifying the Configuration
If the result of formula 1 or formula 2 indicates that power cannot be supplied
properly, use the following procedure to modify the communications power
supply configuration.
• Move the communications power supply towards the center of the network so that there are nodes to both sides of it.
• If there are already nodes on both sides of the power supply, move the
power supply in the direction that requires the higher current.
• If thin cable is being used, replace it with thick cable.
• Move the nodes with higher current requirements closer to the power supply.
If formula 1 or formula 2 is still not satisfied after making the changes listed
above, the network’s power cannot be supplied by a single power supply. Proceed to Step 3.

Step 2: Evaluating the Configuration with Calculations
Group 3:(30 × 0.015 + 3 × 0.005) × 0.30 = 0.1395 V
Group 4:(40 × 0.015 + 4 × 0.005) × 0.15 = 0.093 V
Total voltage drop = 0.0039 + 0.0651 + 0.1395 + 0.093 = 0.3015 V ≤ 4.65 V
In this case, formula 1 is satisfied, so the power supply can supply just the
communications power.
2. Calculate the voltage drop when the communications power supply provides both communications power and internal circuit power (formula 2.)
Group 1:(1 × 0.015 + 1 × 0.005) × 0.545 = 0.0109 V
Group 2:(20 × 0.015 + 2 × 0.005) × 0.84 = 0.2604 V
Group 3:(30 × 0.015 + 3 × 0.005) × 1.1 = 0.5115 V
Group 4:(40 × 0.015 + 4 × 0.005) × 0.85 = 0.527 V
Total voltage drop = 0.0109 + 0.2604 + 0.5115 + 0.527 = 1.3098 V ≥ 0.65 V
In this case, formula 2 is not satisfied, so the power supply cannot supply
the communications power and internal circuit power.

Step 3: Splitting the System into Multiple Power Supplies
If the calculations in step 2 indicate that a single power supply cannot provide
power properly for the network, proceed with this step and install multiple
power supplies to split up the power supply system.
3-6-1
Splitting the Power Supply System
• When there are two or more power supplies in the network, Power Supply
Taps must be used to connect the power supplies.
• Remove a fuse in the Power Supply Tap to supply power to just one side
and split the power supply system.
Once the power supply system is split, return to Step 1 or 2, and evaluate
whether the separated power supply systems can supply power properly.
