Conformance to EC Directives

6

•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:

1The units are designed for installation inside control panels. All units must be installed within control panels.

2Use 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.

3The 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 SmartSlice I/O Units
		from remote stations.
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		The separately available GRT1-END-M Memory End Unit facilitates easy
GRT1-END-M Memory End		replacement of the PROFINET IO Communication Unit. It optionally replaces
Unit		the standard GRT1-END End Unit. No re-configuration using CX-
		ConfiguratorFDT 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.
Easy PROFINET IO		The PROFINET IO Communication Unit is equipped with two ethernet ports.
Network Layout		The built-in ethernet switch functionality allows for easy line configuration of
		the network, as additional external ethernet switches may not be necessary.
MRP Ring Redundancy		To avoid a single network failure causing communication failure within a large
		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.
Facilitating IO Controller		To ensure a safe implementation of the application, the PROFINET IO
Redundancy		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.

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	The SmartSlice I/O Unit's circuit section can be removed, so it is not
Units	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	Before replacing a SmartSlice I/O Unit for maintenance, the parameter data
Restores	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:
	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	2 input bits	GRT1-END-M		End Unit to be mounted to the end of the
	End Unit				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 Com-
	munication Unit when the GRT1-END-M is used.

2The 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.

		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
GRT1-PNT Configuration		The GRT1-PNT DTM is an executable component, provided by OMRON,
DTM		which requires an FDT Container program like OMRON's CX-
		ConfiguratorFDT (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
GRT1-PNT I/O		The I/O Configuration User Interface allows the user to define the
Configuration		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		The Monitoring User Interfaces allows the user to read information from
I/O System		individual SmartSlice I/O Units. It also provides a means to read the Error Log
		of the GRT1-PNT PROFINET IO Communication Unit.
Configuration via GSD File		The GSD file concept is other way of configuration. The GSD file for the
		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.
Third-Party IO Controller		The GSD file for GRT1-PNT can be used to configure most third-party I/O
Units		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.

	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

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:

1Turn ON the PLC power supply and the power supplies of the IO Devices on the network.

2In 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.

3Use the PROFINET IO Controller DTM to assign Device Names to the actual IO Devices in the network.

4Download the network configuration to the PROFINET IO Controller Unit. After downloading the configuration, CX-ConfiguratorFDT will restart the PROFINET IO Controller Unit.

5After restarting the PROFINET IO Controller Unit it will automatically start communication when the PLC goes into RUN/MONITOR mode.
