6-1 Concepts
•EMC Directives
• Low Voltage Directive
EMC Directives
OMRON devices that comply with EC Directives also conform to the r elated
EMC standards so tha t they can be more easil y built in to ot her 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 perfor ma nce o f th e O M RON devices that c omp ly wi th EC Di re ctives will vary depending on the configuration, wi ring, an d other conditio ns of
the equipment or control panel on which the OMRON devices are installed .
The customer must, therefore, perform the fi nal c heck to confir m th at devices
and the overall machine conform to EMC standards.

EC Directives 6
6-2 Conformance to EC Directives
The E5ZN-DRT DeviceNet Communications Unit complies with EC Directives.
To ensure that the machi ne or device in wh ich the U nit is us ed comp lies wit h
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 rei nforced 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 dependin g o n the configuration of the co ntrol pa nel u sed ,
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.
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.

Features and System Configuration Section 1-1
1-1 Features and System Configuration
1-1-1 Features
The DeviceNet Communications Unit enables a DeviceNet master to communicate with multiple E5 ZN Temperature Controllers throu gh the DeviceNet to
monitor their process values, write parameters, and control operation.

Multiple Temperature
Controllers from the
Master
Remote I/O
Communications
Explicit Message
Communications
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 Communic ations Units and othe r types of
slaves can be managed as part of the same system.
The master and DeviceNet Communications Units can share I/O by using
remote I/O communications. Data in the E5 ZN Temperature Contr ollers, such
as process values (PVs) a nd set poi nts (S Ps), c an be al loca ted 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 Communicatio ns Un it, bas ic Temperature Controller
data can be allocate d for communications with the master, such as process values (PVs) and set poin ts (SPs), without re quiring a Confi gurator.
This is called “si mple I/O allocation.” Simple I/O allocation c an be easily
set from the DIP switch on the rear of the DeviceNet Communications
Unit.
• User-set Data Allocations with a Configurator
The specific data req uired for communications with the mas ter can also
be allocated by using I/O allocations from the Configurator.
By executing commands from th e PLC, various o perat io ns can be performed,
including reading/writing specific parameters, such as reading process values
or writing set po ints, and performing operations using o peration commands.
CompoWay/F communications commands can also be executed using explicit
message communications.

The Configurator can be used to create the device parameters for the
DeviceNet Communications Unit , including settings for the DeviceNet Communications Unit and setti ng for the Temperature Controllers. The Config urator can then be used t o download the parameters tog ether 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.
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 ma ster's baud rate is changed, turn
OFF the communications power supply to the DeviceNet Communications
Unit and then turn it ON again.)

Parameters for all Temperature Controllers connec ted to the DeviceNet Communications Unit can be upl oaded or downloaded togeth er. (The parameters
that have been read are stored in the DeviceNet Communications Unit.) When
Temperature Controllers are replaced, the new Controllers can be easily reset
onsite without using a Configurator.
The DeviceNet network communications power voltage values (present value,
peak value, and bottom value) can be stored in the DeviceNet Communications Unit, and the rec orded voltages can be read fro m 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.
The conduction time of th e DeviceNet Communications Unit ’s internal circuit
power supply can be r ecorded. The recorded conductio n time can be read
from the Configurator or us ing explicit messages. By sett ing 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.

The error status for the last four communications errors (the causes and communications power voltage when the communicatio ns error occurred) can be
recorded in the D eviceNet Communications Unit. The recorded communications error history can be read from the Configurator.
The power supply to the Temperature Contr ollers 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.
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 whet her to total the co nducti on tim e or RUN time by setting
the monitor mode.) The recorded total tim e can be read using the Config urator 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.
DeviceNet Communications Units can be connected to the Terminal Units
used for previous (non-DeviceNet) E5ZN Temperature Controllers, so existing
Temperature Controllers can easily be connected to DeviceNet.
The internal circui t power of the DeviceNet Communications Unit is supplie d
from the DeviceNet communications power supply. Therefore, power supply
wiring is not req uir ed for the DeviceNet Co mmunications Unit. (The Temperature Controller power supply must be supplied separately.)

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. (Th e
first two words (four bytes) of the OUT Area are always allocated as Outpu t
Enable Bits).
The IN Area is a llocated for data such as the co mmunicatio ns status and the
process values of the Temperature Control ler channels and th e 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 p rocess values), a nd the ot her can be used for rea ding st atus
(such as Temperature Controller s tatus). 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).

Connecting Temperature Controllers Section 1-3
Controllers can be connected in any order. The unit number of each T emperature Controller is s et using the upper rotar y switch on the front panel o f the
Temperature Controller. Always set a unique unit numb er for each Temperature Controller.
Up to 16 Temperature Controllers can be connected to a single DeviceNet
Communications Unit. RS-48 5 connections also support up to 16 Temperature Controllers.
The E5ZN-SDL Setting Display Unit for E5ZN Temperature Controllers can be
connected at the same time.
Note There is no priori ty between operation commands and s ettings for DeviceNet

and settings from the S etting Display Unit. Do not change the same dat a or
send different operation commands more than one source at the same time.
1-3-2 Temperature Controller Communications
The DeviceNet Communications Unit and Temperature Controllers communicate at a baud rate of 38,400 bps. Set the baud rate using the lower rotar y
switch on the front panel of the Temperature Controllers to 3 (= 38,400 bps).
Communications are performed using a transmission format of 7-bit data, 2
stop bits, and 2 parity bits. These are the default settings. If the default values
have been changed, use the E5ZN-SDL Setting Display Unit to return the
Temperature Controller settings to 7-bit data, 2 stop bits, 2 parity bits.

The unit numbers of the c onnected Temperature Controllers must be regi stered in the configuration in the DeviceNet Communications Unit. The
DeviceNet Communications Unit autom ati ca ll y veri fie s t hat t he r eg ist ered uni t
numbers match the numbers of the Controllers currently able to communicate.
If the unit numbers do not match in the verification proc ess, the Temperature
Controllers will be determined to have an error, causing the following status.
• The TS indicator will flash red.
• The Communicating Flag will turn OFF and the Communications Error
Flag will turn ON for each Temperature Controll er that is not commun icating but is registered as being c onnected to the DeviceNet Communications Unit.
The following two methods can be used to regis ter the conne ction config uration of the Temperature Controller.
1,2,3... 1. Registering with the Configurator or explicit messages (Turn OFF pin 1 on
the DIP switch on the rear of the DeviceNet Communic ations Unit to enable this method)
