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.

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 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.
Device Name Store In GRT1-END-M Memory End Unit
Easy PROFINET IO Network Layout
MRP Ring Redundancy To avoid a single network failure causing communication failure within a large
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.

GRT1-PNT configuration Section 1-4

1-4 GRT1-PNT configuration

PROFINET IO Configuration Means
GRT1-PNT Configuration DTM
GRT1-PNT I/O 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.

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.

Do not exceed 80 W power consumption in one block.
Evaluating the Power Supply Requirements
Unit Power Supply The maximum power consumption for SmartSlice I/O Units is 80 W per block.
1,2,3... 1 Calculate the power consumption of all SmartSlice I/O Units connected to
the PROFINET IO Communication Unit (including other Units like Turnback Units and End Unit). Refer to the GRT1 Series SmartSlice I/O Units Operation Manual (W455) for the power value for each SmartSlice I/O Unit.
2 If the power consumption exceeds 80 W, mount a Right Turnback Unit
(GRT1-TBR) on the SmartSlice I/O Unit at the point where the power consumption still is less than 80 W.
3 Connect the 24 V
Unit power supply to the Left Turnback Unit (GRT1-
DC
TBL) of the next expansion block.
Note 1 The GRT1-TBL is equipped with separate power supply terminals for the Unit power
supply and I/O power supply.
2 When dividing the supply power, always wire (supply) the power from the
same power supply, as shown in the wiring example above.
28
Wiring the GRT1-PNT Unit Section 2-4
I/O Power Supply The maximum I/O current consumption is 4 A.
1,2,3... 1 Calculate the total current consumption used by all external I/O of the
connected SmartSlice I/O Units (including other Units like the Memory End
Unit). Refer to the GRT1 Series SmartSlice I/O Units Operation Manual
(W455) for the (maximum) current value for each SmartSlice I/O Unit. 2 If the current consumption exceeds 4 A or you want to provide separate
systems for inputs and outputs, divide the SmartSlice I/O Units at the
desired point with a GRT1-PD2 I/O Power Supply Unit and provide a
separate external I/O power supply. 3 It is also possible to provide a separate external I/O power supply at a Left
Turnback Unit (GRT1-TBL).
Note 1 The GRT1-TBL is equipped with separate power supply terminals for the Unit power
supply and I/O power supply. 2 Always use isolated power supplies for the power supplies. 3 Power is not supplied through the GCN2-100 Turnback Cable from one block to the
next, as shown in the wiring example above.

2-5 Setting up the PROFINET IO network

2-5-1 Network structure
Various configurations are possible.
When connecting GRT1-PNT unit within a network, the following precautions apply:
- Please be aware any additional Ethernet communication may influence the PROFINET IO Communication.
- It is recommended to separate the PROFINET IO network from the other (IT) network.
- Severely overloading the built-in Ethernet switch with traffic may cause the switch to temporarily block the ports, interrupting all traffic including PROFINET IO communication.
2-5-1-1 Line
A line topology consists of placing multiple IO Devices in series. Many IO Devices, such as the GRT1-PNT Unit, have an ethernet switch integrated in the Unit. This creates an easy way to connect the IO Devices.
Switch
Benefits:
For bigger networks this topology implies lower cabling effort.
This is a traditional field bus structure (compare PROFIBUS-DP).
The Ethernet Switch is optional.
Disadvantages:
Communication paths through many switches affect transmission times.
A malfunction of a single integrated device will result in disconnecting part of the network.
/i
Part Recommendation
Switch (optional) Industrial Ethernet Switch (either managed or unmanaged).
32
Setting up the PROFINET IO network Section 2-5
2-5-1-2 Star
The star topology is the standard-most topology for Ethernet networks. A central switch will allow communication to all individually attached devices.
Switch
Benefits:
Flexible adding and removing devices without interrupting the network.
Easy monitoring and diagnostics of the network.
Disadvantages:
Cabling effort.
Error state of switch will fail complete network.
/i
Part Recommendation
Switch Industrial Ethernet Switch (either managed or unmanaged).
33

2-5-1-3 Tree
The tree topology is a hierarchial combination of multiple star topologies interconnected with each other.
Switch
Switch
Benefits:
Shorter data communication at local node. Avoiding excessive traffic through a single switch.
Hierarchy enables better transparency of the network
Disadvantages:

Setting up the PROFINET IO network Section 2-5
2-5-1-4 Ring
The ring topology is achieved by closing both ends of a line. A network redundancy ring protocol such as MRP (see section 2-5-2 MRP Ring Redundancy) will provide a method of monitoring the state of the network and switch the communication path in case of problems.
Switch / MRP Manager
Benefits:
Malfunction of a single switch / IO Device will not result in disconnecting part of the network. The network redundancy mechanism will automatically maintain the connection with the other devices.
/i
Part Recommendation
Switch Industrial Ethernet Switch supporting MRP manager protocol. Suggestion:
Hirschmann Automation and Control GmbH, Series RS20/30/40, Software Version 4 or higher.
2-5-2 MRP Ring Redundancy
The internal Ethernet Switch in the GRT1-PNT Unit supports the Media Redundancy Protocol (MRP). This protocol, which is part of the PROFINET IO Specification, enables the Unit to be part of a ring-shaped network structure. This ring network structure will give network redundancy.
In case one of the line connections fails, the MRP ensures communication to all IO Devices remains possible through the redundant path. The ring structure can contain up to 50 Units and typically switches to the redundant path within 150 ms (max 500 ms).
The network requires an MRP manager to facilitate the redundancy. As an MRP client, there are no specific settings required for the GRT1-PNT Unit. Please refer to the manual of the used MRP manager unit for details on how to set up and operate the MRP network.

Switch Switch Switch
In case a connection fails, MRP Ring Redundancy ensures communication to all devices through the alternative path.
2-5-3 PROFINET IO Controller redundancy
The PROFINET IO Controller redundancy feature ensures seamless change­over of active PLC / IO Controller to the standby PLC / IO Controller in case of malfunction. To support the PROFINET IO Controller redundancy, a redundancy Function Block can be downloaded from the OMRON website.
Both the active as the standby IO Controller have data exchange with all IO Devices in the network. Only the active IO Controller is in control of the output of the IO Devices.
In case of malfunction of the active IO Controller, the Function Block will transfer control to the standby PLC system. In order to avoid momentary changes in output data during this control change, the Data Hold parameter should be set high enough for the standby IO Controller to take over. This value should be determined experimentally.
For details about setting the PROFINET IO Controller redundancy refer to PROFINET IO Controller manual (W12E).

Installation of Configuration Software Section 2-6

2-6 Installation of Configuration Software

In order to operate the GRT1-PNT and the SmartSlice I/O system the PROFINET IO Controller needs to be configured for communication with the GRT1-PNT. For this purpose OMRON provides the GRT1-PNT DTM via the OMRON web site http://www.omron-industrial.com/
After installation the DTM will run in the FDT Container, allowing the user to set up the I/O configuration and set the parameters of the GRT1-PNT and of the individual SmartSlice I/O Units.
2-6-1 Installation requirements
The following are the minimum requirements for a PC to install the GRT1-PNT DTM configuration software:
PC Pentium III or higher, 500 MHz minimum
Operating System: Windows 2000 SP2 or Windows XP
RAM: 256 MB minimum
Hard disk space: 256 MB minimum

1,2,3... 1 Open the Device Catalogue window in CX-ConfiguratorFDT.
2 Press the Update button to initiate the update sequence.
After updating, the GRT1-PNT DTM will be shown in the list of available devices. It can now be used to setup a PROFINET IO network and configure the Controller Unit.
Note In case the required PROFINET IO Controller DTM has not been installed, this needs
to be done first to allow the full features of the GRT1-PNT DTM to be used.
39
Installation of Configuration Software Section 2-6
2-6-3 GRT1-PNT GSD File
Apart from the GRT1-PNT DTM, OMRON provides a GSD file to allow configuration of third-party PROFINET IO Controller Units, which do not provide an FDT Container. The GSD file - GSDML-V2.1-OMRON-GRT1-PNT-20081205.xml - is available through the OMRON Web site http://www.omron-industrial.com/
Section 3-4-3 Set-up using the GSD file discusses the configuration of the PROFINET IO CX-ConfiguratorFDT using this GSD file.
Using the GSD file for configuration allows the user to configure the Controller Unit for I/O data exchange with the GRT1-PNT and the SmartSlice I/O System. It does not however, provide the acyclic messaging capabilities to access parameters and status information in individual SmartSlice I/O Units. The GRT1-PNT DTM does provide this capability.
The next section will discuss the features of the GRT1-PNT in detail as well as how to set up, configure and operate the SmartSlice I/O System in a PROFINET IO network.

Device name setting and I/O allocation Section 3-1

3-1 Device name setting and I/O allocation

In order to identify the PROFINET IO Communication Unit on the PROFINET IO network, it needs to be assigned a PROFINET IO Device Name. This Device Name is an ASCII string, which is written to the IO Devices by the PROFINET IO Controller DTM or configurator. Using the Device Name the PROFINET IO Controller can configure parameter settings and establish I/O Data Exchange.
For the OMRON PROFINET IO Controller the IO Device is also assigned an IO Device Number. This number is used for the Device-related status and for the acyclic (FINS) communication to the IO Device. This IO Device number is set for each IO Device in the IO Controller DTM and is part of the configuration downloaded to the IO Controller Unit.
Similarly, the individual SmartSlice I/O Units need a unique address to identify each of them to the GRT1-PNT Unit. Contrary to the GRT1-PNT Unit, the individual SmartSlice I/O Unit addresses are assigned automatically at start­up.
3-1-1 Device name setting
For the OMRON CJ1W-PNT21 PROFINET IO Controller, the Device Names are set using the Network Scan View:
42
The actual IO Device can be distinguished either by the MAC address printed on the Unit or the Flash or Signal function of the Scan Tool. This function flashes the indicator LEDs for 3 seconds, identifying the Unit on the rack.
Note 1 Be sure to have unique Device names for each of the IO Devices in the network. As
the name is used as identification, duplicate names will result in communication failure.
2 It is not required to set IP addresses directly to the IO Device using the Scan Tool.
The addresses are set by the IO Controller at startup. Please define the specific IP addresses in the IO Controller configuration.
3 The Device Name should comply to the PROFINET naming rules, for instance no
CAPS are used. This is checked by the Scan Tool.
Device name setting and I/O allocation Section 3-1
3-1-2 Device number setting
The Device Number setting for each IO Device is used for the Device-related status in PLC CIO memory and for the acyclic (FINS) communication to the IO Device. This IO Device number is set in the IO Controller DTM and is part of the configuration downloaded to the IO Controller Unit.
3-1-3 SmartSlice I/O Unit number allocation
The SmartSlice I/O Unit numbers are used to identify the individual SmartSlice I/O Units in the SmartSlice I/O system. These unit numbers are assigned automatically at start-up, when the power is turned ON. The numbering starts from #1 and runs from left to right. It is not necessary for the user to set these numbers.

Note 1 The presence of Turnback units and cables does not influence the automatic
allocation of Unit numbers.

contains two input bits and should be allocated to the last slot of the configuration. 4 Bit-sized SmartSlice I/O Units, e.g. GRT1-ID4, GRT1-OD4 are grouped together in
words. They are mapped from the right-most bit to the left-most bit, in 2-bit units. 5 Word-sized SmartSlice I/O Units, e.g. GRT1-AD2, GRT1-DA2V are mapped to one
or more words, from the low to the high word address. 6 Total size of mapped I/O data can be 64 words output and 64 words input.

3-2-1 Table registration function
Function Overview This function registers the configuration of the SmartSlice I/O Units connected
to the PROFINET IO Communication Unit in a table within the Unit, to allow the registered I/O table to be compared automatically with the actual configuration each time the power is turned ON. The configuration is registered by turning ON (OFF to ON) DIP switch 1 of the PROFINET IO Communication Unit while the SmartSlice I/O Units’ power supply is ON. The registered table is enabled if DIP switch 1 is ON when the power is turned ON. If DIP switch 1 is OFF when the power is turned ON, the registered table is disabled and the Communication Unit will automatically detect the actual I/O configuration and start communication.
Creating a New Registration Table
46
The SmartSlice I/O System’s actual I/O configuration can be read and registered in the table just by switching DIP switch 1 (REGS) from OFF to ON while the PROFINET IO Communication Unit’s power supply is ON. If the registration table is being refreshed, the old contents will be erased.

Comparison with the Registered Table
When DIP switch 1 (REGS) is ON and an I/O configuration table has been registered in the Communication Unit, the actual I/O configuration is automatically compared to the registered table when the power is turned ON. A verification error will occur if a registered I/O Unit cannot join I/O communication or an unregistered I/O Unit is detected. In case of verification errors, the affected SmartSlice I/O Units will not participate in I/O communication. I/O communication will start with the other SmartSlice I/O Units.

Actual configuration
There are the same number of Units, but the I/O data size does not match, so a verification error occurs and this I/O Unit does not participate in communications.
Registration table
The actual configuration is compared to the registered table. Units that do not match the registered table do not participate in I/O communications. I/O communications start with the other I/O Units.
Note 1 Register the I/O configuration table when all of the SmartSlice I/O Units are
communicating, i.e., when the PROFINET IO Communication Unit’s TS indicator is lit green.
2 A mismatch (verification error) with the registered table is indicated at the
PROFINET IO Communication Unit’s TS indicator (flashing red). The error details can be retrieved using the GRT1-PNT DTM. Also, the error history can be read with an explicit message command.

Unit functions Section 3-2
3-2-2 Backup function
Function Overview The backup function records the parameter data of all SmartSlice I/O Units
connected to the PROFINET IO Communication Unit. The parameter data recorded in the Communication Unit can be restored to the SmartSlice I/O Units later with the automatic restore function when a SmartSlice I/O Unit has been replaced.

3 seconds to start the back up.
3 While the data is being backed up, the PROFINET IO Communication
Unit’s TS indicator will flash green every 0.5 second. The TS indicator will stop flashing (not lit) when the backup is completed. If the backup operation fails, the TS indicator will be lit red for 2 seconds.
Note 1 Do not turn OFF the power supply or reset the Configurator while data is being
backed up. The data will not be backed up properly if the power is turned OFF.
2 The backup data will be erased along with the registered I/O configuration table if
DIP switch 1 (REGS) is turned OFF.
3 Backing up the parameter data is recommended to allow easy replacement of faulty
Units in the future.
3-2-3 Automatic restore function
Function Overview When a SmartSlice I/O Unit has been replaced, this function will automatically
download (restore) SmartSlice I/O Unit parameter data that was previously backed up in the PROFINET IO Communication Unit. The following conditions are required to execute the automatic restore function:
DIP switch 1 (REGS) was ON when the power was turned ON, and the registered table is therefore enabled.
DIP switch 3 (ADR) was ON when the power was turned ON, and the automatic restore function is therefore enabled.
Parameter data has been backed up in the PROFINET IO Communication Unit.

3 Remove the main block of the SmartSlice I/O Unit and replace it with a new
SmartSlice I/O Unit of the same type.
4 Mount the terminal block that was removed in step 2 and latch the locks
that were released.
5 When the power is turned ON again, the Communication Unit will
automatically detect the Unit that was replaced and download the backup data. The SmartSlice I/O Unit’s TS indicator will indicate the results of the restore operation.
If the download was successful, the Unit will be reset automatically and join I/O communication normally. The I/O Unit’s TS indicator will be lit green.
If the download failed, the I/O Unit’s TS indicator will flash red.
If the connected Unit is the wrong model, the I/O Unit’s TS indicator will be lit red.
Note 1 Do not turn OFF the power supply or reset the PROFINET IO Communication Unit
while data is being restored. The data will not be restored properly if the power is turned OFF.
2 When a SmartSlice I/O Unit has been replaced with the power ON and the new I/O
Unit joins I/O communication, the new Unit will be compared to the previous one and the parameter data restore operation will start automatically. While data is being restored, the PROFINET IO Communication Unit’s TS indicator will flash green every 0.5 second. The TS indicator will stop flashing (not lit) when the restore oper­ation is completed. If the restore operation fails, the Automatic Restore Monitor Flag (bit 13 of the Communication Unit status flags) will be turned ON and the Communi­cation Unit’s TS indicator will be lit red for 2 seconds.
3-2-4 On-line replacement function
Function Overview When one of the SmartSlice I/O Units connected to the PROFINET IO
Communication Unit must be replaced, the Unit can be replaced without turning OFF the power. The Units can be replaced on-line because the SmartSlice I/O Units are made up of 3 blocks: the base block, main block, and terminal block.
49
Unit functions Section 3-2
When replacing a SmartSlice I/O Unit, leave just the base block connected and replace the main block. I/O communication will continue with the other I/O Units even while the problem Unit is being removed and replaced.
To keep the system online, leave the communications block connected.

6 Turn ON the I/O power supply.
Note 1 When a Unit withdraws from I/O communication during replacement, the
corresponding SmartSlice I/O Unit Communication Withdrawn Flag will go ON and the PROFINET IO Communication Unit’s TS indicator will flash red.
2 Before using the automatic restore function, the preparation for automatic
restoration (creating backup data and turning ON DIP switch 3) must be completed. See section 3-2-3 Automatic restore function for details.
3 Always turn OFF the I/O Unit’s I/O power supply before replacement in order to
prevent false output signals, false input signals, and electrical shocks. In addition, if external power is supplied to the terminal block for a Unit such as a Relay Output
Unit, turn OFF that power supply before replacing the Unit. 4 Only replace one I/O Unit at a time. 5 Always replace the I/O Unit with the same model of I/O Unit. If a Unit is replaced
with a different model, there may be unexpected outputs and the restore operation
may not be completed properly. 6 If the base block is faulty or damaged, turn OFF the power supply and replace the
entire Unit. Even in this case, the I/O Unit’s parameter data will be restored
automatically if the automatic restore function is enabled when the power is turned
ON.
3-2-5 I/O Communication error history monitor

The GRT1-END-M Memory End Unit ensures a quick and easy replacement of the GRT1-PNT in case of malfunction. The END-M Unit contains the Device Name of the IO Device, which is used for the identification within the PROFINET network. When configuring the PROFINET network, any Device Name written by the Scan Tool of the IO Controller DTM to the IO Device will be written immediately into the END-M Unit.
Be sure to execute the Backup function (see section 3-2-2 Backup function) after setting the Device Name at configuration time and afterwards to enable the Automatic Restore function of section 3-2-3 Automatic restore function. In this way also a replacement of a malfunctioning GRT1-END-M can be done without additional configuration actions.
At power-up of the system, the Device Name in the GRT1-PNT is compared to the Device Name that is stored in the GRT1-END-M and updated according to the following rules.
/i
Name in GRT1-PNT Name in GRT1-END-M Resulting Name in GRT1-PNT
(empty) (empty) (empty) (see note 1)
(empty) Name A Name A
Name A (empty) Name A (see note 2)
Name A Name B Name B
Note 1 Configuration with IO Controller DTM/Scan Tool is required.
2 This state will not occur when the Automatic Restore Function is enabled.
I/O Data The GRT1-END-M Memory End Unit will allocate two bits in the PROFINET IO
Communication Unit's Input data area.
/i
Bit Description
0 Device Name bit
OFF: the unit does not contain a Device Name ON: the unit contains a Device Name
1 Reserved for future use
Warning status area The GRT1-END-M Unit has two status areas. Each Unit’s Status Flags are
turned ON and OFF based on the threshold/monitor values set for the function in that Unit. A flag in the Communications Unit will be turned ON only when the corresponding flag has been turned ON in one of those status areas.
The Communications Unit’s Status Flag information is transmitted to the Controller Unit. The
SmartSlice I/O Unit’s status area information can be read
from a Programming Device.
52
The
SmartSlice I/O Unit’s Warning Status Area contains the following 16 bits.
The Warning Status Area provides notification of minor errors detected in the Unit. When any of these flags goes ON, bit 2 of the Communications Unit’s Status Flags is turned ON and that information is transmitted to the Controller Unit.

3-4 Set-up the GRT1-PNT Configuration

Setting up a PROFINET IO Controller Unit to exchange parameters and I/O data with the GRT1-PNT and the SmartSlice I/O System involves defining the I/O configuration to the IO Controller Unit and setting parameters needed at run-time. Refer to Appendix A PROFINET IO technology for more information on PROFINET IO network commissioning.
For configuring the PROFINET IO network with the GRT1-PNT Units, it is required to connect the Personal Computer directly to the ethernet network. It will be able to:
Configure the IO Device names directly on the network.
Use the online functions of the GRT1-PNT DTM to access detailed
SmartSlice I/O Unit parameters.
A direct ethernet connection of the Personal Computer to the PROFINET IO network can also be used to connect to the PLC CPU through the IO Controller. It can be used to configure and monitor the PLC and the PROFINET IO Controller. Please note this is also possible using the other communication interfaces (for instance Toolbus) of the PLC CPU.
This section discusses the methods of configuration.
3-4-1 Defining the PROFINET IO network
Defining the PROFINET IO network in the CX-ConfiguratorFDT, starts with defining the PROFINET IO Controller Unit and assigning the IO Devices to it. Defining and assigning devices can be achieved using drag & drop from the CX-ConfiguratorFDT Device Catalogue. Refer to the CS/CJ-series PROFINET IO Controller Unit Operation Manual (W012E) for more information on how to assemble a network. The figure below shows CX-ConfiguratorFDT with an assembled network in the left window pane and the Device Catalogue opened in the main window pane.
54
To define the I/O Configuration of the GRT1-PNT PROFINET IO Communication Unit, double-click the device in the Network View. A separate configuration window will pop up, which is described in the next section.
Set-up the GRT1-PNT Configuration Section 3-4
3-4-2 Set-up using the DTM
GRT1-PNT DTM window which pops up after double-clicking the GRT1-PNT entry in the Network View is shown below. The window has two tab pages: one for the settings of the PROFINET IO Communication unit itself and one for defining connected I/O Modules.
PROFINET IO tab
Note
The buttons on the bottom will be enabled only when the DTM is on-line.
Comment
The comment field contains comments or descriptions of the station.
Name of Station
This field contains the name of the station, by which it is known to the IO Controller.
IP settings
This sections contains the IP address, network mask and gateway address. These address are assigned by the IO Controller and cannot be changed here.
I/O Module Tab The I/O Module tab, shown below, defines the I/O Configuration for the GRT1-
PNT. This I/O Configuration is downloaded to the PROFINET IO Communication Unit and sent to the physical device by the Communication Unit for verification at the start of communication.

Note 1 Not shown in the list is the first input word, containing the GRT1-PNT Unit status
word (refer to section 3-1-4 SmartSlice I/O allocation to the GRT1-PNT unit for an
explanation on this word). The GRT1-PNT DTM automatically inserts the status
word in the I/O Configuration. 2 The sequence of I/O Devices selected in the I/O Module tab must match the
sequence of physical devices attached to the GRT1-PNT. Otherwise I/O Communi-
cation will not be achieved. 3 The grouping of bit-sized SmartSlice I/O data into words is performed automatically
by the GRT1-PNT.

As an alternative to selecting the I/O Configuration manually, the complete I/O Configuration can be uploaded from the GRT1-PNT Unit. To accomplish this, perform the following steps.
1,2,3... 1 In the Network View, select the GRT1-PNT and right-click the mouse.
2 From the context menu, which pops up, select the option Go Online. 3Press the Upload button. This will initiate an upload of all SmartSlice I/O
Information, i.e. I/O Configuration, Unit types and Unit parameters. From
this upload, the I/O Configuration in the Configuration list will be assembled
automatically.
Note Uploading may take some time, due to the amount of parameters.
Editing SmartSlice I/O Unit Settings
56
After making the I/O configuration selection, the settings of individual SmartSlice I/O Units can be set or changed. To do this, perform the following steps.
Set-up the GRT1-PNT Configuration Section 3-4
1,2,3... 1 Select the SmartSlice I/O Unit in the I/O Configuration.
2 Press the Edit button below the I/O Configuration list. The appropriate
setting window will pop up.
Using the On-Line Functions
Note 1 In order to download/upload settings for individual SmartSlice I/O Units, the DTM
has to be on-line with the physical GRT1-PNT Unit, i.e. it has to be able to establish a connection with the device.
2 In the case of the GRT1-AD2 some parameter settings will affect the I/O Configura-
tion, i.e. it will change the I/O size for that particular SmartSlice I/O Unit. In that case, the I/O Configuration for the PROFINET IO Controller Units needs to be (re-) downloaded. If this is required, an appropriate warning window will pop up.
3 The configuration options and windows for individual SmartSlice I/O Units are
described in detail in the GRT1 Series SmartSlice I/O Units Operation Manual (W455).
4 The GRT1-PNT Unit does not support the Output Hold/Clear settings for the
SmartSlice I/O Units in case of host communication/PROFINET IO fault (Idle action). The Output Hold/Clear settings for SmartSlice bus fault (Fault action) is supported.
In order to use the online functions of the GRT1-PNT DTM, be sure to connect the Personal Computer directly to the ethernet network. The communication will go directly to the GRT1-PNT unit, not through the IO Controller.
At the bottom of the GRT1-PNT DTM are four buttons which will be enabled after the DTM has established communication with the physical device. Switching to on-line must be done via the FDT Container. To switch to on-line, perform the following steps in the configurator.
1,2,3... 1 In the Network view, right-click the GRT1-PNT.
2 From the context menu, which pops up, select the option Go Online.
The functions of the buttons are discussed below.
Upload Button Pressing the Upload button will initiate an upload of all SmartSlice I/O
Information, i.e. I/O Configuration, Unit types and Unit parameters. From this upload, the I/O Configuration in the Configuration list will be assembled.
57
Set-up the GRT1-PNT Configuration Section 3-4
Note Uploading may take some time, due to the amount of parameters.
Download Button Pressing the Download button will initiate a download of all SmartSlice I/O
Information, i.e. I/O Configuration, Unit types and Unit parameters.
Compare Button Pressing the Compare button will initiate a comparison between the I/O
Configuration and parameters of all SmartSlice I/O Units and the data stored within the DTM. In case a mismatch is found, a warning screen will pop up to notify the user.
Reset Button Pressing the Reset button will initiate a system reset, i.e. the GRT1-PNT as
well as the attached SmartSlice I/O Units will be reset. A Reset will also force the connected SmartSlice I/O Units to restore their settings from their non volatile storage. In some cases a reset is a necessity to force the SmartSlice IO Units to use newly written parameters.
Note If changes have been made via the SmartSlice I/O Unit’s parameter windows, which
require a system reset, the user is notified of this through a pop notification window.
3-4-3 Set-up using the GSD file
In case third-party IO Controller Units are used, of which the Configuration software does not support FDT/DTM technology, the GRT1-PNT GSD File can be used to configure that IO Controller.
Note 1 Using the GSD File allows for I/O Configuration and I/O data exchange with the IO
Controller Unit. It does not provide easy access to other Unit parameters. 2 PROFINET IO Controller Units can also be configured using the GSD File, although
the DTM is available and has many more features.
The figure below shows the Generic IO Device DTM, used in CX­ConfiguratorFDT to handle GSD Files.
Defining the I/O Configuration
58
To define the I/O configuration, perform the following steps.
Set-up the GRT1-PNT Configuration Section 3-4
1,2,3... 1 Select the Configuration Modules.
2 Select the individual I/O modules in the same sequence as they are
physically connected to the Communication Unit GRT1-PNT by clicking
Add Module. 3 Click on the added module to show the available modules. 4 Select the required module. 5 If applicable, repeat the previous steps to add another module.
Observe the following.
The 2- and 4-point Digital Units occupy 2 or 4 bits of I/O data. Adjacent
digital Input Units or Output Units must be assembled in to 1 word.
To assemble multiple Digital Units, first select the appropriate Unit listed in
the available Modules list, which is not marked with a asterisk. This will
indicate the start of a new word. For the subsequent units the I/O modules
marked with an asterisk must be selected until a word has been filled up.
When using digital input (or output) units after an analog input (or output
unit), a new word has to be allocated. Select a module which is not marked
with an asterisk.
After a word has been filled up, a new word must be started by selecting
again the next I/O module not marked with an asterisk.
Do not attempt to put Input Units and Output Units in one and the same
word. This will result in a parameterization error, after downloading the
configuration to the Controller Unit.
The 8-point digital, analog and counter Units occupy whole words.
To further explain the mapping sequence, an example is given below.
Example To illustrate how the Digital and Analog SmartSlice I/O Units are mapped on to
I/O words, and how to implement this using the GSD File, consider the table below.
/i

3-4-4 Mapping I/O data
The I/O Configuration can now be mapped on to the PROFINET IO Controller Unit. The PROFINET IO Controller Unit provides a means to map individual I/O Configuration modules to specific memory areas.
Example As an example, the I/O mapping of the I/O Configuration made using the
Generic Device IO DTM is shown in the window below.
60
The window above shows the SmartSlice I/O Input data, mapped onto CIO 3300 to 3304. The first row indicates the COM Status word, the other rows indicate the GRT1-ID Units.
After setting up the I/O Configuration, it needs to be downloaded to the Controller Unit.

PROFINET IO technology

A-1 Introduction to PROFINET

As a common solution for the industrial communication, the PROFIBUS International organisation introduced the PROFINET Industrial Ethernet standard. PROFINET is the next step for building on the current:
PROFIBUS DP, the well-known and established fieldbus;
Industrial Ethernet.
PROFINET is the innovative and open standard for Industrial Ethernet. PROFINET satisfies all requirements for automation technology. With PROFINET, solutions can be implemented for factory and process automation, for safety applications and for motion control. PROFINET is now standardized in IEC 61158 and IEC 61784.
The use of PROFINET minimizes the cost of installation, engineering and commissioning.
PROFINET IO Distributed field or I/O Devices are integrated through PROFINET IO. This
uses the usual IO view of PROFIBUS DP, whereby the IO data of field devices are cyclically transmitted to the process image of the PLC.
The PROFINET IO device model is based on the PROFIBUS implementation, consisting of insertion (slots) and groups of I/O channels (subslots). The characteristics of the field devices are described via a General Station Description (GSD) on an XML basis.
The installation, monitoring and maintenance of PROFINET IO will be familiar to engineers accustomed to PROFIBUS DP. The distributed field devices are allocated to a controller during configuration.
PROFINET CBA The PROFINET component model has its application in distributed automation
systems. This is mainly used for intelligent field devices with programmable functionality as well as controllers. PROFINET CBA divides distributed, complex applications into autonomous units of manageable size.
A distributed automation system based on these autonomous units simplifies the modularization of plants and machines, permitting separate and cross­vendor development.
PROFINET based on a component model is described using a PROFINET Component Description (PCD), which is XML-based.
83

A-2 PROFINET Communication

PROFINET uses Ethernet and TCP, UDP and IP as basis for the communication between the devices.
TCP/IP and UDP/IP For non-time critical messaging PROFINET uses standard Ethernet
mechanisms over TCP/IP and UDP/IP.
Field devices are addressed using a MAC and IP address. This is similar to the standard Ethernet communication. In these protocols, the networks are identified based on the IP address. Within a single network the MAC address is used for the addressing of the target devices.
This addressing features enables integration with the IT world without limitation. The OMRON I/O Devices can accordingly support the OMRON Ethernet protocols, enabling additional communication with OMRON PROFINET devices.
TCP provides an error-free transmission of data from sender to receiver. It establishes a connection between the two stations before the transmission is complete. This connection is monitored during operation and disconnected after the transmission is complete.
UDP does not guarantee an error-free transmission of data. However, the UDP is connectionless. Each message is an individual transmission. Because of the lack of overhead (connection establishment, monitoring, etc.), this protocol is more suitable for time-critical applications.
RT and IRT The TCP/IP and UDP/IP communication protocols apply a considerable
amount of control overhead which will slow down data transmission speed which is required for PROFINET applications. To facilitate Real-Time capabilities for data exchange, the PROFINET uses a specific protocol of Real-Time (RT) Communication. This protocol cancels some of the flow control and addressing in comparison with the TCP/IP and UDP/IP.
For the prioritized transmission of RT-frames, Real-Time communication uses the VLAN tag as defined in IEEE 802.1Q.
For demanding communication tasks of high performance within PROFINET, for instance Motion Control, the Isochronous Real Time (IRT) has been developed. This communication requires specific hardware to establish integrated switch functionality and cycle synchronization.
84

A-3 PROFINET Distributed I/O

The focus of PROFINET IO is to have cyclic data exchange between a controller and multiple often simple communication devices. The aim is to have high performance and ease to use. The experience of the PROFIBUS fieldbus has been integrated into the PROFINET IO from user’s point of view.
The PROFINET IO distinguishes the following different device roles. Please note a single device can have multiple roles.

6 IO device DP slave Device for receiving sensor signals and
controlling actuators like valves, switches and frequency converters.
IO Controller A PROFINET IO Controller is the central device in the PROFINET network. It
has the control over the state of the network and processes the data and alarms. The IO Controller typically is a PLC Unit that processes the data and alarms in the user program. It establishes the connection to the devices on the network during system start-up.
IO Supervisor A PROFINET IO Supervisor is an optional device in the network, which has
temporary access to the field devices. It is typically an engineering station for monitoring or commissioning of the system.
IO Device A PROFINET IO Device is a remotely connected field device, close to the
manufacturing process. It is configured by the IO Controller to cyclically interchange process data with the IO Controller. The IO Device can have multiple connections to different IO Controllers / IO Supervisors in the network and will generate alarms if problems occur with the communication or the manufacturing process.
Device Model The PROFINET IO application layer describes the modules of an IO Device in
a similar way as for PROFIBUS DP. A PROFINET IO Device consists of slots for which the modules/submodules can be inserted. The technical data concerning the slots and subslots are defined in the GSD file of a device.
Slot A Slot is the physical place of insertion of a module in an IO Device. Various
subslots are located in the various slots, which contain data for cyclic data exchange.
Subslot Subslots provide an additional addressing layer. They enable grouping of
similar channels within a slot. Each slot has to comprise at least one subslot with [1:n] I/O channels.
Index The index specifies the data related to a specific subslot, to be read or written
acyclically.

Provider/Consumer Model The data exchange between IO Controller and the IO Devices is carried out
based on the provider-consumer model. The provider sends its data to the consumer without a request from the other device. The consumer processes the data. The provider (as the consumer) is either the IO Controller or the IO Device.
The Input Output Provider Status (IOPS) indicates the status of the data source (valid or invalid) for each of the modules as part of the data exchange message. This can be the Output data for the IO Controller and the Input data for the IO Device. The provider status is either bad or good, implying the received data is either invalid or valid for use. For example the Output data of the IO Controller is set to bad in case the PLC is in Program mode.
The Input Output Consumer Status (IOCR) indicates the feedback on the provided data received before. This status (Bad or Good) is indicated in the Input data for the IO Controller and the Output data for the IO Device. As an example when considering the IO Controller Redundancy: an IO Device will only feedback to the active IO Controller it has consumed its output (status Good). The standby IO Controller will get IOCR Bad status as response.
87

A-4 PROFINET Communication Services

The IO Controller establishes a connection to its IO Devices based on the configuration which has been given by the user. The Application Relation (AR) includes all data needed to achieve this data exchange. A single AR can include multiple Communication Relations (CRs). For implementation of different communication profiles, such as PROFIdrive, the PROFINET IO contains special addressing elements. These elements are called Application Process Identifier (APIs).
The following CRs are possible for each API.
IOCR, consisting of input, output or multicast
Record data CR for exchange of acyclic data
Alarm-CR for communicating alarms and other events
The data exchange between the IO Device and the IO Controller occurs in a poll cycle as configured by the IO Controller. The user is capable to set this update cycle in the IO Controller configuration for each of the IO Devices. This results in mutual monitoring of functional operability (watchdog function). All cyclic data is provided with a status that encodes the validity of the data.
