Precautions for Safe Use
1. Use and store the product within the specified ambient temperature and
humidity ranges. If several products are mounted side-by-side or arranged
in a vertical line, the heat dissipation will cause the internal temperature of
the products to rise, shortening the service life. If necessary, cool the products using a fan or other cooling method.
2. Provide sufficient space around the product for heat dissipation. Do not
block the vents on the product.
3. Use the product within the noted supply voltage and rated load.
4. Be sure to confirm the name and polarity for each terminal before wiring
the terminal block and connectors.
5. Do not connect anything to unused terminals.
6. Use the specified size of crimp terminals (M3, width: 5.8 mm max.) for wiring the terminal block.
7. To connect bare wires to the terminal block, use AWG22 to AWG14 (crosssectional area: 0.326 to 2.081 mm
AWG28 to AWG16 (cross-sectional area: 0.081 to 1.309 mm
terminals. (Length of exposed wire: 6 to 8 mm)
8. Ensure that the rated voltage is achieved no longer than 2 s after turning
the power ON.
9. Turn OFF the power first before drawing out the product. Never touch the
terminals or the electronic components, or subject them to physical shock.
When inserting the product, do not allow the electronic components to contact the case.
10. Do not remove the inner circuit board.
11. Output turns OFF when shifting to the initial setting level in certain modes.
Take this into consideration when setting up the control system.
12. Allow the product to warm up for at least 30 minutes after the power is
turned ON.
13. Install surge absorbers or noise filters in devices near the product that generate noise (in particular, devices with an inductance component, such as
motors, transformers, solenoids, and magnetic coils). If a noise filter is
used for the power supply, check the voltage and current, and install the
noise filter as close as possible to the product. Separate the product as far
as possible from devices generating strong high-frequency noise (e.g.,
high-frequency welders and high-frequency sewing machines) or surges.

14. Keep the wiring for the product's terminal block and connector separate
from high-voltage, high-current power lines to prevent inductive noise. Do
not run the wiring parallel to or in the same cable as power lines. The influence of noise can also be reduced by using separate wiring ducts or shield
lines.
15. Install an external switch or circuit breaker and label them clearly so that
the operator can quickly turn OFF the power.

EC Directives
•EMC Directives
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.
Conformance to EC Directives
The E5AR/E5ER-DRT Digital Controllers comply 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. 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.
2. Units complying with EC Directives also conform to the Common Emission
Standard (EN61326). 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.
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 Master
Unit.

Fe at ur e s Section 1-1
1-1 Features
The E5AR-DRT and E5ER-DRT (E5AR/ER-DRT) are Digital Controllers that
use DeviceNet for communications.
Overview
1-1-1 Outline
The E5AR/ER-DRT Digital Controllers are slaves that connect to the
DeviceNet open field network. DeviceNet communications enable controlling
operation, collecting measurement data, and writing settings from a host computer or PLC. The E5AR/ER-DRT support both remote I/O communications
and explicit message communications.
Remote I/O communications allow the master and the E5AR/ER-DRT to automatically share data via high-speed I/O without any special programming of
the master. Remote I/O communications are particularly suited to operation
control, error warnings, and monitoring applications.
Explicit messages use a communications protocol for sending commands and
receiving responses. The main application for explicit message communications is for changing E5AR/ER-DRT settings data.

Remote I/O
Communications
The master and E5AR/ER-DRT Digital Controllers can share I/O by using
remote I/O communications. Data in the E5AR/ER-DRT Digital 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.

Explicit Message
Communications
• By sending commands from a PLC, various operations can be performed,
including reading/writing specific monitor values and 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.
Automatically Detects
Baud Rate
• Previously, the baud rate had to be set for each slave, but the E5AR/ERDRT Digital Controllers automatically detect and match 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 Digital Controller and then turn it ON again.)
1-1-4 Default Communications Settings
The default settings required for communications when E5AR/ER-DRT are
used as DeviceNet slaves are listed in the following diagram.

Refer to the DeviceNet Operation Manual (Cat. No. W267) for information
such as the order for turning ON power to the master and slaves and master I/
O tables.
1-1-5 Data Allocation
E5AR/ER-DRT communications data must be allocated for the IN and OUT
Areas for remote I/O communications. Up to 100 words each can be allocated
for the IN and OUT Areas. The data for each word is allocated using the
parameters communications write data allocations 1 to 100 and communications read data allocations 1 to 100.
Unused words can be specified to reserve space according to data types or to
otherwise reduce the number of words.
Refer to 4-2 I/O Allocation on page 4-2 for details on allocation methods.
1-1-6 Remote I/O Communications
Read/write table data is automatically read and written when communications
start. The Communications Write setting must be set to ON to write data from
the master to the E5AR/ER-DRT. Data will not be written to the Digital Controller if the Communications Write setting is OFF. The following diagram
shows communications with the default data allocation parameters.

the IN and OUT Areas from the default values.
To split the IN Area used by the E5AR/ER-DRT into two
areas, select E5AR/ER-DRT in the master’s Edit Device
Parameters Window and set the connection in the detailed
settings.
When the IN Area is split into two areas, for example, operating parameters, such as set points and process values,
can be allocated in IN Area 1, and status values can be allocated in IN Area 2. For example, IN Area 1 can be allocated
in the DM Area and IN Area 2 can be allocated in the CIO
Area.
Enable the master’s scan list and change the PLC to RUN
Mode.
Remote I/O communications will start, and the contents of
the IN and OUT Areas in the master and E5AR/ER-DRT
Digital Controller will be synchronized.
Send explicit messages from the master.
Explicit messages can be used to perform control and mon-
itoring that cannot be achieved using the IN and OUT Areas
alone, by sending explicit messages to the E5AR/ER-DRT
Digital Controller.

Operating
Procedures
Observe the following precautions when editing device parameters using the
Configurator.
• It is recommended that device default values are uploaded before the
parameters are edited because the EDS parameter defaults and the
device defaults are different.
• If “Unit No.” (communications unit number) is displayed in the Communications Setting parameter group, set the “Unit No.” to the node address.
• If “Input 2 Type” is displayed in the Input Initial Setting parameter group
for the E5AR-@@@B-DRT, E5ER-@@@B-DRT, E5AR-@@@F-DRT, or
E5ER-@@@F-DRT, set the “Input 2 Type” to 15. The default value may
not be downloaded.
• Related settings are not initialized when data is downloaded from the
Configurator. Refer to the Appendix in the E5AR/E5ER Digital Controller
User’s Manual (Cat. No. H124) for information on how to correctly set
related data.
• The automatic selection range upper limit (DV) can be set from the front
panel or it can be set using the automatic selection range upper limit (PV)
parameter (PID*AUT(PV)). When using the automatic selection range
upper limit (PV) parameter, set the value obtained from the following
equation:
Automatic selection range upper limit (PV) = Automatic selection range
upper limit (DV) + Sensor setting range lower limit
2-1-3 Setting Node Addresses
DeviceNet node addresses are set in the communications setting level. Set
the node addresses on the front panel of the E5AR/ER-DRT.
• The node address will be 0 if an address between 64 and 99 is set.

The number of words allocated will depend on the E5AR/ER-DRT communications data allocations. The following points are important when setting node
addresses or allocating I/O memory.
• Do not allocate the same words to other slaves.
• Make sure the I/O area does not exceed the valid range.
2-2 Functions Supported Only by the E5AR/ER-DRT
A Configurator is used to make settings for the network power monitor function, accumulated ON (RUN) time monitor function, and control at error function.
2-2-1 Network Power Monitor Function
The E5AR/ER-DRT has a network power monitor function that turns ON the
Communications Power Voltage Monitor Error Flag in the General Status
when the communications power voltage drops below the set monitor value.
The monitor value for the network power voltage is set using the Configurator
and is found in the General Setting parameter group.
2-4
Functions Supported Only by the E5AR/ER-DRT Section 2-2
2-2-2 Accumulated ON (RUN) Time Monitor Function
The E5AR/ER-DRT has accumulated ON (RUN) time monitor functions which
record internally the total time communications power is supplied or the accumulated RUN (control) time. The Unit Maintenance Flag in the General Status
will turn ON if the accumulated time exceeds a set monitor value.
The Detection Mode and Detection Time are set using a Configurator and are
found in the General Setting parameter group.
The ON (RUN) time monitor function can be used as a guide for replacing the
E5AR/ER-DRT Digital Controller.
Measurement unit: 0.1 h
Measurement range: 0 to 429496729.5 h (Stored data: 00000000 to
FFFFFFFF hex).
Note (1) The ON or RUN time is held even when the power is turned OFF.
(2) Both the ON and RUN time monitor functions cannot be used at the same
time for one word.
(3) The accumulated time will not be measured if communications power is
not supplied to the E5AR/ER-DRT.
(4) The E5AR/ER-DRT Digital Controller checks the ON/RUN status of the
target channel approximately every 0.1 h (6 min.).
