Make sure that the ratings and performance characteristics of the product are
sufficient for the systems, machines, and equipment, and be sure to provide
the systems, machines, and equipment with redundant safety mechanisms.

This manual provides information for installing and operating OMRON
DeviceNet products. Be sure to read this manual before operation and keep
this manual close at hand for reference during operation.

!WARNING It is extremely important that a PLC and all PLC Units be used for the speci-

fied purpose and under the specified conditions, especially in applications that
can directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PLC system to the above mentioned applica­tions.

3 Safety Precautions

!WARNING Never attempt to disassemble any Units or touch the terminal block while

power is being supplied. Doing so may result in serious electrical shock.

!WARNING Do not apply voltages or currents outside the specified ranges to a Slice I/O

Unit. Doing so may cause a malfunction or fire.

!WARNING Always turn OFF the I/O power supply to the I/O Unit before performing online

replacement or connecting/disconnecting wiring, including fixing a loose wire.
In addition, if external power is supplied to the terminal block for a Unit such
as a Relay Output Unit or AC Input Unit, turn OFF that power supply before
replacing the Unit. Not turning OFF these power supplies may result in false
output signals, false input signals, or electrical shock.

xvii

Operating Environment Precautions 4

!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.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.

• The PLC will stop operation when its self-diagnosis function detects any
error or when a severe failure alarm (FALS) instruction is executed. As a
countermeasure for such errors, external safety measures must be pro­vided to ensure safety in the system.

• The PLC outputs may remain ON or OFF due to deposits on or burning of
the output relays, or destruction of the output transistors. As a counter­measure for such problems, external safety measures must be provided
to ensure safety in the system.

• When the 24-VDC output (service power supply to the PLC) is overloaded
or short-circuited, the voltage may drop and result in the outputs being
turned OFF. As a countermeasure for such problems, external safety
measures must be provided to ensure safety in the system.

• Slice I/O Terminals will continue operating even if one or more I/O Units is
removed from or falls out of the Slice I/O Terminal, i.e., the other I/O Units
will continue control operations, including outputs. As a countermeasure
for such a possibility, external safety measures must be provided to
ensure safety in the system.

!WARNING The CPU Unit refreshes I/O even when the program is stopped (i.e., even in

PROGRAM mode). Confirm safety thoroughly in advance before changing the
status of any part of memory allocated to Output Units, Special I/O Units, or
CPU Bus Units. Any changes to the data allocated to any Unit may result in
unexpected operation of the loads connected to the Unit. Any of the following
operations may result in changes to memory status.

• Transferring I/O memory data to the CPU Unit from a Programming
Device

• Changing present values in memory from a Programming Device

• Force-setting/-resetting bits from a Programming Device

• Transferring I/O memory files from a Memory Card or EM file memory to
the CPU Unit

• Transferring I/O memory from a host computer or from another PLC on a
network

longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi­tions at installation and remains within the specified conditions during the life
of the system.

5 Application Precautions

Observe the following precautions when using the Slice I/O Units.

• Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal
lines, momentary power interruptions, or other causes.

• Provide external interlock circuits, limit circuits, and other safety circuits in
addition to any provided within the PLC to ensure safety.

• Use the power supplies specified in the operation manuals.

• If the system is installed at a site with poor power supply conditions, take
appropriate measures to ensure that the power supply remains within the
rated voltage and frequency specifications.

• Provide circuit breakers and other safety measures to provide protection
against shorts in external wiring.

• Always ground the system to 100

Ω or less when installing the system to

protect against electrical shock.

• Mount the PLC securely on DIN Track or with screws.

• Always turn OFF the power supply when mounting a Slice I/O Unit.

• Always turn OFF the communications power supply and the power sup­plies to the PLC and Slaves before attempting any of the following.

• Mounting or removing a Unit such as an I/O Unit, CPU Unit, Memory
Cassette, or Master Unit.

• Mounting or removing Remote I/O Terminal circuit sections.

• Assembling any devices or racks.

• Setting rotary switches.

• Connecting or wiring cables.

• Connecting or disconnecting connectors.

• Do not attempt to disassemble, repair, or modify any Units.

• Be sure that all the terminal screws are tightened to the torque specified
in the relevant manuals. Loose screws may cause fire, malfunction, or
damage the Unit.

xix

Application Precautions 5

• Be sure that all the mounting screws and cable connector screws are
tightened to the torque specified in the relevant manuals.

• Be sure that all the communications connector screws are tightened
securely. (The communications connector screw torque is 0.5 to 0.6 N·m.)

• Use the correct wiring components when wiring.

• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals.

• Double-check all wiring before turning ON the power supply.

• When wiring or performing other tasks, do not allow metal objects such as
wire strands to enter the Unit.

• Always follow the electrical specifications for terminal polarity, communi­cations path wiring, power supply wiring, and I/O jumpers. Incorrect wiring
can cause failures.

• Always wire the Unit as shown in the manual.

• Be sure to press terminals until they are fully seated.

• Mount Units only after checking terminal blocks completely.

• Before mounting a wired terminal block to the main block, be sure that the
terminal block-main block combination is correct.

• Be sure that the communications cable connectors and other items with
locking devices are properly locked into place.

• Do not drop the Unit or subject the Unit to excessive vibration or shock.
Doing so may cause malfunction or damage to the Unit.

• Use the special packing box when transporting the Unit. Ensure that the
product is handled carefully so that no excessive vibration or impact is
applied to the product during transportation.

• Check the user program for proper execution before actually running it
with the system.

• Do not bend or pull the cables excessively.

• When connecting communications cables, always turn OFF the PLC
power supply, all Slave power supplies, and all communications power
supplies.

• Observe the following precautions when wiring the communications
cables.

• Wire the communications cables separately from the power lines or
high-tension lines.

• Do not bend the communications cables excessively.

• Do not pull on the communications cables excessively.

• Do not place objects on top of the communications cables.

• Route communications cables inside ducts.

• Always enable the scan list before operation.

• Before clearing the scan list of a Unit that has user-allocated remote I/O,
always confirm that no errors occur after the I/O Area setting is changed
to fixed allocation.

• When adding a new node to the network, check that the new node’s baud
rate is the same as the baud rate set on the other nodes.

• Do not extend connection distances beyond the ranges given in the spec­ifications.

• Be sure that the Slice I/O Units are lined up correctly when mounting
them.

xx

EC Directives 6

• Correctly connect the Slice I/O Units to each other. The I/O power supply
will become disconnected if the base blocks on the Slice I/O Units are not
connected correctly.
While outputs are being transmitted from the Communications Unit, the
output indicators on the Slice Output Unit will be lit, but the outputs will
actually be OFF.

6 EC Directives

DeviceNet products conform to EMS and low-voltage level directives as fol­lows:

EMC Directive

OMRON devices that comply with EC Directives also conform to the related
EMC standards, so that they can more easily be built in to other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards. Whether they 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.

Low Voltage Directive

Devices that operate at voltages from 50 to 1,000 VAC or 75 to 1,500 VDC
must satisfy the appropriate safety requirements. The applicable standard is
EN 61131-2.

Complying with EC Directives

1,2,3... 1. The Slice I/O Units are designed for installation inside control panels. All

Slice I/O Units must be installed within control panels.

2. Use reinforced insulation or double insulation for the DC power supplies
used for the communications power supply, internal circuit power supply,
and the I/O power supplies. Ensure that stable outputs can be provided
even if a 10-ms interruption occurs at the input.

3. The Slice I/O Units conform to the EN 61131-2 (Immunity Zone A), EN
61000-6-2, and EN 61000-6-4 standards. AC power connections to Slice
I/O Units must use a protection network if the severity levels for Zone A are
exceeded. The 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 examples shows how to reduce noise.

1,2,3... 1. Noise from the communications cable can be reduced by installing ferrite

cores on the communications cable within 10 cm of the DeviceNet Unit and
DeviceNet Communications Unit.

Slice I/O Terminal Introduction Section 1-1

1-1 Slice I/O Terminal Introduction

A Slice I/O Terminal is a building-block style remote I/O terminal made up of a
Communications Unit and a number of Slice I/O Units, which each provide a
small number of I/O points. The Slice I/O Units communicate with the host by
remote I/O communications (cyclic communications) through the Communica­tions Unit. Remote I/O communications (cyclic communications) can be
started just by setting the Communications Unit’s node address and turning
ON the power supply.

Since the Slice I/O Units expand the system in small I/O increments, a flexible
system can be assembled to exactly match various customer applications,
with less labor and space.

1-1-1 Features of the GRT1-series Slice I/O Units

The GRT1-series Slice I/O Units have the following features.

Features Shared by all Units

Small I/O Increments The GRT1-series Slice I/O Units have just a few I/O points (2 to 4 points) per

Unit, so the application can be flexibly constructed to match the space and
capacity requirements.

Building-block Style
Termina ls

Slice I/O Terminals are building-block style Units that can be expanded by
attaching additional Slice I/O Units to the side of the Terminal. Up to 64 Slice I/
O Units can be connected to one Communications Unit.

Time-saving Screwless
Termina l Blocks

Slice I/O Units are equipped with screwless clamp terminal blocks, which can
be wired just by inserting the wire into the terminals. Wires can be removed
just by pressing the release button and pulling out the wire.

Example: DeviceNet

PLC

Serial connection
(For setting, monitoring, and operating)

Slice I/O Terminal Introduction Section 1-1

Parameter Backup and
Restore

Before replacing a Slice I/O Unit for maintenance, the parameter data set in
the I/O Unit can be backed up in the connected Communications Unit. The
backed up parameter data is compared with the replacement I/O Unit’s data
and the backed up data is restored to the replacement I/O Unit.

Online Replacement of I/O
Units

The Slice I/O Units are made up of 3 blocks (the base block, main block, and
terminal block) that can be separated from each other. This means you can
leave the base block connected to the Slice I/O Terminal with power supplied
to the Slice I/O Terminal and replace the main block or terminal block.

Note Turn OFF the I/O power supply before replacing Slice I/O Unit

blocks. Also turn OFF any external power supplied to the terminals.

Automatic Baud Rate
Recognition

It isn’t necessary to set the baud rate on the GRT1-series Slice I/O Units.

Automatic Allocation of
Unit Numbers

Unit numbers are allocated automatically to the connected Slice I/O Units
from left to right and stored within the Communications Unit. It is not neces­sary for the user to set these numbers.

Remote I/O
Communications

GRT1-series Slice I/O Units communicate with the host Master by remote I/O
communications through the Communications Unit. The Slice I/O Units’ data
is collected in the Communications Unit and exchanged with the Master in a
batch.

Unit Conduction Time
(Power ON Time) Monitor

This function records the total time that the Slice I/O Unit's internal circuit
power has been ON. A warning level can be set in the Unit and a warning flag
will be turned ON when the set warning time is exceeded. The Power ON
Time can be read with an explicit message command or from the Configura­tor.

Unit Comments A user-set name can be assigned to each Unit and recorded in the Unit.

Connected Device
Comments

User-set names can be assigned to each I/O device (sensor, valve, etc.) con­nected to a Unit and recorded in the Unit.

Communications Error
History Monitor

The communications error log within the Unit can collect the four most recent
communications errors (communications error cause code and communica­tions power supply voltage when error occurred). The information can be read
with an explicit message command or from the Configurator.

Last Maintenance Date The date on which maintenance was performed can be written in the Unit.

The date can be written from the Configurator.

Digital I/O Unit Features

I/O Power Supply Monitor This function detects whether the I/O power is being supplied and turns ON a

warning flag in the Unit if the I/O power supply is OFF. The flags can be read
with an explicit message command or from the Configurator.

Input Filter The input filter function reads the input value several times during the set

interval and removes irregular data caused by noise and switch chattering.
This function can also be used to create ON/OFF delays.

Sensor Power ON Delay When the I/O power has gone OFF, the sensor power ON delay function

blocks inputs for the first 100 ms after the I/O power is turned back ON. This
function prevents incorrect inputs caused by inrush current at startup after the
I/O power is turned ON.

4

Slice I/O Terminal Introduction Section 1-1

Contact Operation
Counter

This function can count the number of times each input or output contact
changes from OFF to ON (maximum resolution: 50 Hz). A warning set value
can be set in the Unit to monitor the number of contact operations, and turn
ON a warning flag in the Status Area when the set value is reached. The Con­figurator or explicit messages can be used to read the information.

Note The Contact Operation Counter and Total ON Time Monitor cannot be used at

the same time for a single contact.

Total ON Time Monitor This function can record the total ON time of devices connected to the Unit,

such as sensors and relays. The total time is stored in the Unit and can be
read by the Configurator or explicit messages. A warning set value can be set
in the Unit to monitor the total ON time, and turn ON a warning flag in the Sta­tus Area when the set value is reached.

Note The Total ON Time Monitor and Contact Operation Counter cannot be used at

the same time for a single contact.

Operation Time Monitor This function can measure and monitor an Input Unit’s operating time. The

time required for a bit to go ON or OFF can be measured at high speed within
the Unit, so that ladder programming is not required to measure the operating
time. The trigger edge (ON

→OFF or OFF→ON), input number, and output

number can be selected freely, providing flexibility when testing. A warning set
value can be set in the Unit to monitor the operating time, and turn ON a
warning flag in the Status Area when the set value is reached.

Analog I/O Unit Features

Setting the Number of AD
Conversion Points

The conversion cycle when both analog input points are used is 2.42 ms max.
The AD conversion cycle can be shortened by reducing the number of points
used (i.e., the number of AD conversion points).

Moving Average Analog Input Terminals can calculate the average of the past eight analog

input values to produce a stable input value even when the input value is
unsteady.

Scaling Scaling allows values to be converted according to the industry unit required

by the user. It reduces the number of operations requiring ladder program­ming in the Master CPU Unit. Scaling also supports an offset function for com­pensating for errors in scaled values.

Peak/Bottom Hold The maximum (peak) and minimum (bottom) values input to Analog Input Ter-

minals can be held. These values can then be compared with alarm set val­ues, and flags turned ON accordingly to indicate the status (comparator
function).

Top/Valley Hold (Input
Units Only)

The top and valley values for values input to Analog Input Terminals can be
held. The timing of tops and valleys can be monitored with the Top/Valley
Detection Timing Flags. The top and valley values can be compared with
alarm set values, and flags turned ON accordingly to indicate the status (com­parator function).

Rate of Change The rate of change for values input to Analog Input Terminals can be obtained

for each sampling cycle.

Comparator Values input to Analog Input Terminals or values after math processing can be

compared to the alarm set values (HH, H, L, and LL), and the result indicated
with the Analog Status Flags. If the result is outside the set range, the Normal
Flag (pass signal) is turned ON.

Off-wire Detection With Analog Input Terminals, disconnections can be detected in wiring for

analog (voltage or current) inputs that are enabled as AD conversion points.

5

Slice I/O Terminal Introduction Section 1-1

The status can be checked at the Master using the Off-wire Detection Flag.
This function is valid only for the input ranges 4 to 20 mA and 1 to 5 V.

User Adjustment Input or output values can be adjusted to compensate for errors in the input or

output voltage or current resulting from the characteristics or connection
methods of the I/O device. Compensation is performed by applying linear con­version based on the points corresponding to 0% and 100%.

Cumulative Counter A cumulated value that approximates the integral of analog input or output val-

ues over time can be calculated and read.

Communications Error
Output (Output Units
Only)

The values output by Output Units when errors occur can be set for each out­put.

Temperature Input Unit Features

Moving Average Temperature Input Units can calculate the average of the past eight input val-

ues to produce a stable input value even when the input value is unsteady.

Scaling Scaling allows values to be converted according to the industry unit required

by the user. It reduces the number of operations requiring ladder program­ming in the Master CPU Unit. Scaling also supports an offset function for com­pensating for errors in scaled values.

Peak/Bottom Hold The maximum (peak) and minimum (bottom) values input to Temperature

Input Units can be held. These values can then be compared with alarm set
values, and flags turned ON accordingly to indicate the status (comparator
function).

Top/Valley Hold The top and valley values for values input to Temperature Input Units can be

held. The timing of tops and valleys can be monitored with the Top/Valley
Detection Timing Flags. The top and valley values can be compared with
alarm set values, and flags turned ON accordingly to indicate the status (com­parator function).

Rate of Change The rate of change for values input to Temperature Input Units can be

obtained for each sampling cycle.

Comparator Values input to Temperature Input Units or values after math processing can

be compared to the alarm set values (HH, H, L, and LL), and the result indi­cated with the Temperature Status Flags. If the result is outside the set range,
the Normal Flag (pass signal) is turned ON.

Off-wire Detection With Temperature Input Units, disconnections can be detected individually for

each sensor input. The status can be checked at the Master using the Off­wire Detection Flags.

Input Error Detection
Disable

Detection of input errors, including off-wire detection, can be disabled for
channels that are not used.

User Adjustment Input or output values can be adjusted to compensate for errors in the input or

output voltage or current resulting from the characteristics or connection
methods of the I/O device. Compensation is performed by applying linear con­version based on the points corresponding to 0% and 100%.

Cumulative Counter A cumulated value that gives the integral of analog input values over time can

be calculated and read.

Top or Valley Count The numbers of times that the top or valley value is reached can be counted,

e.g., in an application in which the temperature input value varies in a fixed
cycle of temperature change. The host will be notified with a flag when the
number of cycles exceeds the set value.

6

Slice I/O Terminal Introduction Section 1-1

Temperature Zone
Counter

The temperature zone counter can be used to measure how long the temper­ature input value is within a user-set temperature range in 1-second incre­ments. The host will be notified with a flag when the measured value exceeds
the set value.

Data Comparison between
Channels

The temperature differences between input channels 0 and 1 can be calcu­lated and compared to a set value. The host will be notified with a flag when
the temperature difference exceeds a set value.

Counter Unit and Positioning Unit Features

Counter Each Unit provides one high-speed counter with a 32-bit resolution. Counting

is performed in linear fashion, and encoder signals up to 60 kHz can be input
with Counter Units and up to 100 kHz can be input with Positioning Units. The
Counter Units support 24-V inputs and the Positioning Unit supports either
24-V or line-driver inputs (settable).

Counter Input Modes The counter can be set to any of the following input modes:

• Phase differential

×1

• Phase differential ×2

• Phase differential

×4

• Pulse/direction

•Up/down

Speed Measurement The output pulse frequency is measured and can be read from the I/O area at

any time.

Digital Inputs The Counter Unit supports an input that can be set to operate either as a digi-

tal input or an encoder Z-signal input. The Positioning Unit provides both a
digital input and an encoder Z-signal input.

The digital input can be set to reset the counter, preset the counter, or capture
the present counter value. Any of these actions can be set to be performed on
the rising or falling edge of the digital signal.

The Z-signal input of the Positioning Unit can be set to reset the counter in
various ways.

Digital Outputs Each Counter Unit provides one digital output and the Positioning Unit pro-

vides two digital outputs. A digital output can be used as a general-purpose
output, or it can be controlled using a settable counter value comparison
range.

Comparison Range A comparison range can be enabled for the counter value to control a digital

output. The output will be turned ON or OFF depending on the relationship
between the counter value and the range that is set. Each Counter Unit pro­vides one comparison range.
