Precautions for Safe Use
xi
● Installation
1) Connect the DeviceNet Communications Unit to the left side of a Basic Unit or an End Unit.
2) The EJ1 cannot be used linked to a CJ-series PLC.
● Service Life
1) Use the product within the following temperature and humidity ranges.
Temperature:
−10 to 55°C (with no icing or condensation)
Humidity: 25% to 85%
When the Temperature Controller is incorporated in a control panel, make sure that the controller’s
ambient temperature and not the panel’s ambient temperature does not exceed 55
°C.
2) The service life of electronic devices like the Temperature Controller is determined by the service life of
internal electronic components. Component service life is affected by the ambient temperature: the higher
the temperature, the shorter the service life and the lower the temperature, the longer the service life.
Therefore, the service life can be extended by lowering the temperature of the Temperature Controller.
3) Mounting two or more Temperature Controllers side by side, or mounting Temperature Controllers above
each other may cause heat to build up inside the Temperature Controllers, which will shorten their service
life. If the Temperature Controllers are mounted above each other or side by side, use forced cooling by
fans or other means of air ventilation to cool down the Temperature Controllers. However, be sure not to
cool only the terminals. Doing so will result in measurement errors.
● Precautions for Operation
1) It takes a certain amount of time for the outputs to turn ON from after the power supply is turned ON. Due
consideration must be given to this time when designing control panels, etc.
2) It takes 30 minutes from the time the product is turned ON until the correct temperature is indicated.
Always turn ON the power supply at least 30 minutes before starting temperature control.
3) Avoid using the Temperature Controller near a radio, television set, or other wireless device. Its use would
result in reception disturbance.
Precautions for Correct Use
xii
Be sure to thoroughly read and understand the manual provided with the product, and check the following points.
■ EC Directives
•EMC Directives
• Low Voltage Directive
Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards. Whether the products conform to the standards in the system
used by the customer, however, must be checked by the customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.
Preparations for Use
Timing Check point Details
Purchasing the product Product appearance After purchase, check that the product and packaging are not dented
or otherwise damaged. Damaged internal parts may prevent optimum
control.
Product model and
specifications
Make sure that the purchased product meets the required specifications.
Setting the Unit Product installation
location
Provide sufficient space around the product for heat dissipation. Do
not block the vents on the product.
Wiring Terminal wiring Do not subject the terminal screws to excessive stress (force) when
tightening them.
Make sure that there are no loose screws after tightening terminal
screws to the specified torque of 0.25 to 0.30 N·m.
Be sure to confirm the polarity for each terminal before wiring the terminal block and connectors.
Power supply inputs Wire the power supply inputs correctly. Incorrect wiring will result in
damage to the internal circuits.
Operating environment Ambient temperature The ambient operating temperature for the product is −10 to 55°C (with
no condensation or icing). To extend the service life of the product,
install it in a location with an ambient temperature as low as possible.
In locations exposed to high temperatures, if necessary, cool the products using a fan or other cooling method.
Vibration and shock Check whether the standards related to shock and vibration are satis-
fied at the installation environment. (Install the product in locations
where the conductors will not be subject to vibration or shock.)
Foreign particles Install the product in a location that is not subject to liquid or foreign
particles entering the product. If sulfide, chlorine, or other corrosive
gases are present, remove the source of the gas, install a fan, or use
other countermeasures to protect the product.

Conformance to EC Directives
The EJ1 DeviceNet Communications Unit complies with EC Directives. To
ensure that the machine or device in which the Unit is used complies with EC
Directives, the Unit must be installed as follows:
1,2,3... 1. The Unit must be installed within a control panel.
2. You must use reinforced insulation or double insulation for the DC power
supplies used for the communications power supply, internal power supply,
and I/O power supplies.
3. Units complying with EC Directives also conform to the Common Emission
Standard (EN50081-2). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used,
other devices connected to the control panel, wiring, and other conditions.
You must therefore confirm that the overall machine or equipment complies
with EC Directives.
4. The Unit is a Class A product (products for industrial environments). In residential environment areas it may cause radio interference, in which case
the user may be required to take adequate measures to reduce interference.
The following example shows one means of reducing noise.
1,2,3... 1. Noise from the communications cable can be reduced by installing a ferrite
core on the communications cable within 10 cm of the DeviceNet Unit.

1-1 Features and System Configuration
1-1-1 Features
The DeviceNet Communications Unit enables a DeviceNet master to communicate with multiple EJ1 Temperature Controllers through the DeviceNet to
monitor their process values, write parameters, and control operation.
Using DeviceNet Functions
Simultaneously Managing
Multiple Temperature
Controllers from the
Master
Up to 16 Temperature Controllers can be connected to a single DeviceNet
Communications Unit. The DeviceNet Communications Unit is connected to
the master as a DeviceNet slave. Up to 63 slaves can be connected to a single master, so multiple DeviceNet Communications Units and other types of
slaves can be managed as part of the same system.
Remote I/O
Communications
The master and DeviceNet Communications Units can share I/O by using
remote I/O communications. Data in the EJ1 Temperature Controllers, such
as process values (PVs) and set points (SPs), can be allocated for communications with the master to enable sending and receiving the allocated data via
remote I/O communications, without requiring special programming.
• Remote I/O Communications without a Configurator
Using the DeviceNet Communications Unit, basic Temperature Controller
data can be allocated for communications with the master, such as process values (PVs) and set points (SPs), without requiring a Configurator.
This is called “simple I/O allocation.” Simple I/O allocation can be easily
set from the DIP switch of the DeviceNet Communications Unit.
• User-set Data Allocations with a Configurator
The specific data required for communications with the master can also
be allocated by using I/O allocations from the Configurator.
Expansion Remote I/O to
Enable Using More Than
100 Words of Parameters
Expansion remote I/O can be used to read and write parameters. Specific
parameters allocated in I/O memory of the master can be switched to a variety of parameters by using memory operations. This function enables manipulating more than 100 words of parameters. Even if the number of parameters
to be read and written increases, modifications can be handled simply by
changing operations in the memory of the master.
Explicit Message
Communications
By executing commands from the PLC, various operations can be performed,
including reading/writing specific parameters, such as reading process values
or writing set points, and performing operations using operation commands.
CompoWay/F communications commands can also be executed using explicit
message communications.
Setting, Monitoring, and
Operating the
Temperature Controller
from the Configurator
The Configurator (Ver. 2.2 or higher) or CX-Integrator (Ver. 2.2 or higher) can
be used to create the device parameters for the DeviceNet Communications
Unit, including settings for the DeviceNet Communications Unit and setting for
the Temperature Controllers. The Configurator can then be used to download
the parameters together to the DeviceNet Communications Unit and Temperature Controllers. (See note.)
The Configurator can also be used to monitor Temperature Controller process
values, and execute operation commands for the Temperature Controllers.
The Configurator can be used to copy parameters between Temperature Controller channels, allowing the initial parameters of Temperature Controllers
requiring the same or similar parameters to be easily set.
3
Features and System Configuration Section 1-1
Automatically Detects
Baud Rate
Previously, the baud rate had to be set for each slave, but the DeviceNet Communications Unit automatically detects and matches the baud rate of the master, so this setting is not required. (If the master's baud rate is changed, turn
OFF the communications power supply to the DeviceNet Communications
Unit and then turn it ON again.)
Wide Range of Maintenance Functions
Copy Function (Uploading
or Downloading
Temperature Controller
Parameters)
Parameters for all Temperature Controllers connected to the DeviceNet Communications Unit can be uploaded or downloaded together. (The parameters
that have been read are stored in the DeviceNet Communications Unit except
for bank parameters and G3ZA and G3PW parameters.) When Temperature
Controllers are replaced, the new Controllers can be easily reset onsite without using a Configurator.
Monitoring Network Power
Volt age
The DeviceNet network communications power voltage values (present value,
peak value, and bottom value) can be stored in the DeviceNet Communications Unit, and the recorded voltages can be read from the Configurator. By
setting the voltage monitor value in the DeviceNet Communications Unit, notification will be sent to the master if the voltage level drops below the monitor
value.
Monitoring the Unit
Conduction Time
The conduction time of the DeviceNet Communications Unit's internal circuit
power supply can be recorded. The recorded conduction time can be read
from the Configurator or using explicit messages. By setting a monitor value
for the conduction time in the DeviceNet Communications Unit, notification will
be sent to the master when the total time exceeds the monitor value.
Unit Comments Any name can be set for a DeviceNet Communications Unit and recorded in
the Unit. Specifying names enables the user to easily differentiate the applications of the DeviceNet Communications Units when setting and monitoring
them from the Configurator.
Setting Temperature
Controller Comments
A name can be set for each Temperature Controller channel connected to the
DeviceNet Communications Unit and recorded in the DeviceNet Communications Unit. Specifying names enables the user to easily differentiate the function of each channel when setting and monitoring them from the Configurator.
Monitoring
Communications Error
History
The error status for the last four communications errors (the causes and communications power voltage when the communications error occurred) can be
recorded in the DeviceNet Communications Unit. The recorded communications error history can be read from the Configurator.
Monitoring Temperature
Controller Power Status
The power supply to the Temperature Controllers can monitored to confirm
that power is ON and send notification of the status to the master. (The power
status can be checked for Temperature Controllers connected to the
DeviceNet Communications Unit only.) The power status of the Temperature
Controllers can be read from the Configurator or using explicit messages.
Monitor Temperature
Controller Conduction
Time and RUN Time
The conduction time of the Temperature Controller's internal circuit power
supply or the RUN time of the Temperature Controller can be totaled and
recorded. (Select whether to total the conduction time or RUN time by setting
the monitor mode.) The recorded total time can be read using the Configurator or explicit messages. By setting a monitor value in the DeviceNet Communications Unit, notification will be sent to the master if the Unit conduction time
exceeds the monitor value.

Features and System Configuration Section 1-1
1-1-2 Overview of Unit Communications Functions
Remote I/O
Communications
DeviceNet Communications Unit data is shared with the master's IN Area and
OUT Area through DeviceNet. Up to 100 words (200 bytes) each can be used
as the IN Area and OUT Area for the DeviceNet Communications Unit. (The
first word (two bytes) of the OUT Area is always allocated for the OUT Enable
Bit).
The IN Area is allocated for data such as the communications status and the
process values of the Temperature Controller channels and the OUT Area is
allocated for the set points of the channels and other data.
When using a CS/CJ-series DeviceNet Unit as the master, the IN Area can be
divided into two areas. One is normally used for input data (such as Temperature Controller process values), and the other can be used for reading status
(such as Temperature Controller status). Even when the IN Area is divided
into two areas, however, the total number of words that can be used for the IN
Area is still 100 words (200 bytes).

Explicit Message
Communications
Explicit message commands can be sent from the master to the DeviceNet
Communications Unit to read or write the parameters of the connected Temperature Controllers. CompoWay/F communications commands that were
previously used for Temperature Controllers can also be sent (in explicit message format).
The DeviceNet Communications Unit's own parameters can also be read or
written.
