3 Safety precautions

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 operation of the
PLC. 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 short­circuited, 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.

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

vii

Operating environment precautions 4

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/force-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.

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 or electrocution.

5 Application precautions

Observe the following precautions when using the GRT1-PNT PROFINET IO
Communication Unit.

Caution

Failure to abide by the following precautions could lead to faulty operation of
the Unit or the system. Always heed these precautions.

• Install double safety mechanisms to ensure safety against incorrect signals that
may be produced by broken signal lines or momentary power interruptions.

• When adding a new device to the network, make sure that the baud rate is the
same as other stations.

• When adding a new SmartSlice I/O Unit to the Communication Unit, make
sure that the GRT1-PNT PROFINET IO Communication Unit is powered
down, to prevent unexpected results when starting up the new station.

• Use specified communication cables.

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

• Always turn OFF the power supply to the personal computer, Slaves, and
Communication Units before attempting any of the following:

• Mounting or dismounting the GRT1-PNT PROFINET IO Communication Unit,

Power Supply Units, I/O Units, CPU Units, or any other Units.

• Assembling a Unit.

• Setting DIP-switches or rotary switches.

• Connecting or wiring the cables.

manuals. Incorrect tightening torque may result in malfunction.

• Always use the power supply voltage specified in this manual.

• Double-check all the wiring and connection of terminal blocks and connectors
before mounting the Units.

• Take appropriate measures to prevent foreign objects from entering the unit when
mounting or wiring it. Failure to do so, may result in unit damage, electric shock or
fire.

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

• Observe the following precautions when wiring the communication cable.

• Separate the communication cables from the power lines or high-tension lines.

• Do not bend the communication cables.

• Do not pull on the communication cables.

• Do not place heavy objects on top of the communication cables.

• Be sure to wire communication cable inside ducts.

• Use appropriate communication cables.

• Take appropriate measures to ensure that the specified power with the rated
voltage and frequency is supplied in places where the power supply is unstable. An
incorrect supply power may result in malfunction.

• Install external breakers and take other safety measures against short-circuits in
external wiring. Insufficient safety measures against short-circuits may result in
burning.

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

• When transporting or storing the product, cover the PCB’s with electrically
conductive materials to prevent LSI’s and IC’s from being damaged by static
electricity, and also keep the product within the specified storage temperature
range.

• When transporting the Unit, use special packing boxes and protect it from being
exposed to excessive vibration or impacts during transportation.

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

• Do not remove the network cable during operation. Removing the network cable
result in communication failures.

ix

Conformance to EC Directives 6

WARNING

Failure to abide by the following precautions could lead to serious or possibly fatal
injury. Always heed these precautions.

• Always connect to a class-3 ground (100 Ω or less) when installing the 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.Not doing so may result in serious accidents.

6 Conformance to EC Directives

6-1 Applicable directives

• EMC (ElectroMagnetic Compatibility) Directives

• Low-voltage directive

6-2 Concepts

OMRON units complying with EC Directives also conform to related product
standards making them easier to incorporate in other units or machines. The
actual products have been checked for conformity to product standards.
Whether the products conform to the standards in the system used by the
customer, however, must be checked by the customer.
Product related performance of OMRON units complying with EC Directives
will vary depending on the configuration, wiring, and other conditions of the
equipment or control panel in which OMRON devices are installed. The
customer must, therefore, perform final checks to confirm that units and the
overall system conforms to product standards.
A Declaration of Conformity for the GRT1-PNT PROFINET IO Communication
Unit can be requested at your nearest OMRON representative.

6-3 Conformance to EC Directives

PROFINET IO units should be installed as follows, for the complete
configuration to meet the EC directives:
1 The units are designed for installation inside control panels. All units must

be installed within control panels.

2 Use reinforced insulation or double insulation for the DC power supplies

used for the communication 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 GRT1-PNT PROFINET IO Communication Unit meets the generic

emission standard. However as EMC performance can vary in the final
installation, additional measures may be required to meet the standards. It
should therefore be verified that the overall machine or device also meets
the relevant standards. You must therefore confirm that EC directives are
met for the overall machine or device, particularly for the radiated emission
requirement (10 m).

1-1 Overview of GRT1-series SmartSlice I/O Units

The GRT1-Series SmartSlice I/O Units are building-block style I/O Devices,
which can be expanded in small I/O increments. This provides the possibility
to configure I/O systems which exactly match the various customer
applications. SmartSlice I/O Units communicate with the PROFINET IO
Controller Unit by remote I/O communication through a PROFINET IO
Communication Unit. The figure below shows a typical I/O configuration.

1-2 GRT1-PNT PROFINET IO Communication Unit

1-2-1 Features

The GRT1-PNT PROFINET IO Communication Unit for SmartSlice I/O
controls data exchange between the PROFINET IO Controller and SmartSlice
I/O Units over the PROFINET IO network as an IO Device. For an overview of
the PROFINET IO technology refer to Appendix A PROFINET IO technology.

I/O Data Exchange Cyclic I/O data exchange is used to exchange I/O data between the

PROFINET IO Controller and SmartSlice I/O Units through the PROFINET IO
Communication Unit. In addition to I/O data, status information in the
PROFINET IO Communication Unit can be accessed from the PROFINET IO
Controller Unit.

FINS/UDP Interface The PROFINET IO Communication Unit is provided with a FINS/UDP

Interface. This enables not only the PROFINET IO Controller to access the
SmartSlice I/O Units using OMRON FINS messaging, but any device which
supports a UDP interface (such as a Personal Computer using CX-Server
Lite). This allows for configuration and monitoring of the
from remote stations.

SmartSlice I/O Units

Simplified Start-up The PROFINET IO Communication Unit can be set up easily, just by wiring the

Unit, configuring the PROFINET IO network using CX-ConfiguratorFDT and
making simple DIP switch settings. The Unit's configuration is read
automatically when the power is turned ON and I/O is also automatically
allocated in the SmartSlice I/O Units.

Facilitating IO Controller
Redundancy

The separately available GRT1-END-M Memory End Unit facilitates easy
replacement of the PROFINET IO Communication Unit. It optionally replaces
the standard GRT1-END End Unit. No re-configuration using CX­ConfiguratorFDT is required in case of replacement of the Communication
Unit. The PROFINET IO Device name, used for identification of the
Communication Unit on the PROFINET IO network, is backed up and restored
to and from the GRT1-END-M Memory End Unit.

The PROFINET IO Communication Unit is equipped with two ethernet ports.
The built-in ethernet switch functionality allows for easy line configuration of
the network, as additional external ethernet switches may not be necessary.

part of the network, the units can be set up in a ring topology. MRP Ring
Redundancy as specified in the PROFINET standards ensures
communication to all remaining devices through the redundant path.

To ensure a safe implementation of the application, the PROFINET IO
Communication Unit and the PROFINET IO Controller offer the possibility of
PLC system redundancy. Two IO Controllers (active and standby) are present
in a network connected to all I/O Devices. This feature ensures a fast change
from active to standby PLC / IO Controller in case of malfunction.

Simplified I/O Wiring All SmartSlice I/O Units that connect to a PROFINET IO Communication Unit

are equipped with screw-less clamp terminal blocks. Wiring to external I/O is
accomplished just by inserting the wire into the terminals, eliminating the need
to tighten terminal screws.

3

GRT1-PNT PROFINET IO Communication Unit Section 1-2

Table Registration The configuration of the SmartSlice I/O Units (mounting order and I/O size)

connected to a PROFINET IO Communication Unit can be registered in a
table simply by setting a DIP switch. Once the table has been registered, the
actual configuration is compared to the registered configuration each time that
the power is turned ON. If the configuration does not match, a status flag is
turned ON in the PROFINET IO Controller to indicate the error.

On-line Replacement of I/O
Units

The SmartSlice I/O Unit's circuit section can be removed, so it is not
necessary to turn OFF the Communication Unit’s power to replace a Unit.
Communication can be maintained in the remaining (connected) Units.

Parameter Backup and
Restores

Before replacing a SmartSlice I/O Unit for maintenance, the parameter data
set in all SmartSlice I/O Units can be backed up in the PROFINET IO
Communication Unit by toggling a DIP switch. Another DIP selects the mode
to automatically write the back-up parameter data to the replacement
SmartSlice I/O Unit.

1-2-2 System configuration

The PROFINET IO Communication Unit connects to the IO Controller by an
Ethernet network cable and it connects to the SmartSlice I/O Units by directly
coupling the Units together.

I/O Data Exchange The I/O Unit data in the PROFINET IO Communication Unit is shared with the

IO Controller's Input and Output Areas through the PROFINET IO network.
The I/O Units' data is collected in the PROFINET IO Communication Unit and
exchanged with the IO Controller cyclically.

Messaging Services The GRT1-PNT PROFINET IO Communication Unit also supports messaging

services using FINS/UDP, allowing the user to send acyclic message
commands addressed to the GRT1-PNT Unit or individual SmartSlice I/O
Units. This can be sent from the PLC or for instance the Personal Computer.

End Unit for PROFINET IO Always install an End Unit on the last I/O Unit in the system. For the

PROFINET IO Communication Unit there are two options:

/i

Type I/O points Model number Description

End Unit -- GRT1-END End Unit to be mounted to the end of the

SmartSlice I/O Terminal.

Memory
End Unit

2 input bits GRT1-END-M End Unit to be mounted to the end of the

SmartSlice I/O Terminal.
The unit has a backup of the IO Device
Name of the Communication Unit.

In case of replacement of the PROFINET IO Communication Unit, the
PROFINET IO Device Name will be restored from the GRT1-END-M Unit to
the new Communication Unit. In case of the standard GRT1-END, additional
configuration download using CX-ConfiguratorFDT is required after
replacement.

Note 1 Unlike the standard End Unit, the Memory End Unit will count as one SmartSlice I/O

Unit. Up to 63 SmartSlice I/O Units can be connected to one PROFINET IO Com­munication Unit when the GRT1-END-M is used.

2 The GRT1-END-M Memory End Unit functionality only applies to the PROFINET IO

Communication Unit. Although the Memory End Unit has the basic End Unit funtion­ality, the Unit is not aimed to be used together with other Communication Units.

Configuration

The PROFINET IO Controller Unit requires a configuration before it can
exchange I/O data with any of its IO Devices. For this configuration information
on the IO device must be available. OMRON provides two means to facilitate
IO Controller Unit configuration.

• A GRT1-PNT DTM

• A GRT1-PNT GSD file

The GRT1-PNT DTM is an executable component, provided by OMRON,
which requires an FDT Container program like OMRON's CX­ConfiguratorFDT (see also Appendix A PROFINET IO technology, FDT/DTM
Technology). The DTM runs inside this FDT Container and provides its own
User Interface. It can access GRT1-PNT and SmartSlice I/O Unit data using
FINS/UDP and present that to the user. It can also save the settings, using the
features of the FDT Container program. The GRT1-PNT DTM provides the
user with the following features.

• PROFINET I/O Configuration

• Configuration of individual SmartSlice I/O Units

• Monitoring of the SmartSlice I/O System

The I/O Configuration User Interface allows the user to define the
configuration of SmartSlice I/O Units attached to the PROFINET IO
Communication Unit. It also allows the user to make parameter settings for
individual SmartSlice I/O Units.
The I/O Configuration is used by the PROFINET IO Controller Unit when
mapping the I/O data of individual SmartSlice I/O Units onto the PLC memory
areas. It is also sent by the PROFINET IO Controller Unit to the GRT1-PNT for
verification when establishing communication. The I/O Configuration sent by
the PROFINET IO Controller Unit must match the physical configuration
attached to the GRT1-PNT PROFINET IO Communication Unit, in order to
proceed with I/O data exchange.

Monitoring the SmartSlice
I/O System

Configuration via GSD File The GSD file concept is other way of configuration. The GSD file for the

Third-Party IO Controller
Units

The Monitoring User Interfaces allows the user to read information from
individual SmartSlice I/O Units. It also provides a means to read the Error Log
of the GRT1-PNT PROFINET IO Communication Unit.

GRT1-PNT is an XML-based file, which contains all options required to
configure a PROFINET IO Controller Unit. The file can be loaded by the
configuration software of the IO Controller Units, which will then present the
information to the user to allow the appropriate selections to be made.
The drawback of the GSD file is that - unlike the GRT1-PNT DTM - it only
provides setting options for configuring the PROFINET IO. The GSD file does
not provide the means to access data of the SmartSlice I/O Units directly.

The GSD file for GRT1-PNT can be used to configure most third-party I/O
Controller Units. The GRT1-PNT GSD file contains all the necessary
parameters to allow the user to configure the IO Controller Unit for I/O data
exchange.

GRT1-PNT configuration Section 1-4

Note 1 The GRT1-PNT DTM can also be used in third-party configuration software pro-

vided that this software supports the FDT/DTM concept.

2 With the CX-ConfiguratorFDT FDT Container OMRON also provides a Generic IO

Device DTM, an FDT/DTM interface between the FDT Container program and GSD
files. Alternatively, this DTM can be used to set up an IO Controller Unit, using the
GRT1-PNT GSD file. This Generic IO Device DTM however, does not provide the
means to access data of the SmartSlice I/O Units directly.

Downloading the
configuration

After setting up the configuration, it must be downloaded to the PROFINET IO
Controller Unit. The download process depends on the IO Controller Unit
used.

Basic operating procedure Section 1-5

1-5-2 Preparations for use

The following procedure shows the basic steps required before using the
PROFINET IO Communication Unit and the SmartSlice I/O Units.

Initial setup procedure 1 Mount the GRT1-PNT Unit and the SmartSlice I/O system on the DIN rail.

The maximum number of SmartSlice I/O Units can be 64 (including GRT1-

END-M End Unit).
2 Wire the SmartSlice I/O Units and the GRT1-PNT Unit's power supply.
3 Wire the PROFINET IO network, to connect the Communication Unit to the

PROFINET IO Controller Unit.
4 Turn ON the power to the Unit and the I/O.
5 Turn ON (from OFF to ON) DIP switch 1 on the front of the PROFINET IO

Communication Unit. When switch 1 is turned ON, the existing SmartSlice

I/O Unit configuration (connection order and I/O size) is registered in the

PROFINET IO Communication Unit as a registered table. After the table is

registered, leave pin 1 ON to enable the table.

Note The next time the power is turned ON, the actual SmartSlice I/O Unit configuration at

power on is automatically compared to the registered table. Any SmartSlice I/O Units
that do not match the registered table (connection order or I/O size) will not participate
in I/O communication. I/O communication will start with the other SmartSlice I/O Units.

Configuration procedure Use the following procedure to configure the IO Controller Unit together with

the PROFINET IO Communication Unit using CX-ConfiguratorFDT and the IO
Controller and IO Device DTMs:
1 Turn ON the PLC power supply and the power supplies of the IO Devices

on the network.
2 In CX-ConfiguratorFDT, create a network and define the parameters and

I/O configurations for the PROFINET IO Controller Unit settings and the

allocated IO Devices. Choose the update rate for each IO Device.
3 Use the PROFINET IO Controller DTM to assign Device Names to the

actual IO Devices in the network.
4 Download the network configuration to the PROFINET IO Controller Unit.

After downloading the configuration, CX-ConfiguratorFDT will restart the

PROFINET IO Controller Unit.
5 After restarting the PROFINET IO Controller Unit it will automatically start

communication when the PLC goes into RUN/MONITOR mode.
