Application Precautions

5

Always use the power supply voltages specified in the operation manuals. An incorrect voltage may result in malfunction or burning.

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

Install external breakers and take other safety measures against short-cir- cuiting in external wiring. Insufficient safety measures

Make sure that all the Backplane mounting screws, terminal block screws, and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction.

Leave the label attached to the Unit when wiring. Removing the label may result in malfunction if foreign matter enters the Unit.

Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.

Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. Connection of bare stranded wires may result in burning.

Observe the following precautions when wiring the communications cable.

Separate the communications cables from the power lines or high-ten- sion lines.

Do not bend the communications cables past their natural bending radius.

Do not pull on the communications cables.

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

Always lay communications cable inside ducts.

Use appropriate communications cables.

Make sure that the terminal blocks, expansion cable connectors, and other items with locking devices are locked in place.

Wire all connections correctly according to instructions in this manual.

Double-check all wiring and switch settings before turning ON the power supply. Incorrect wiring may result in burning.

Mount terminal blocks and connectors only after checking the mounting location carefully.

Check the user program (ladder program and other programs) and parameters for proper execution before actually running it on the Unit. Not checking the program may result in unexpected operation.

Confirm that no adverse effect will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation.

Changing the operating mode of the PLC.

Force-setting/force-resetting any bit in memory.

Changing the present value of any word or any set value in memory.

After replacing a Unit, resume operation only after transferring to the new CPU Unit, Special I/O Unit, or CPU Bus Unit the contents of the DM Area, HR Area, programs, parameters, and other data required for resuming operation. Not doing so may result in an unexpected operation.

Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any static build-up. Not doing so may result in malfunction or damage.

xxv

Conformance to EC Directives

6

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

CPU Bus Units will be restarted when routing tables are transferred from a Programming Device to the CPU Unit. Restarting these Units is required to read and enable the new routing tables. Confirm that the system will not be adversely affected before allowing the CPU Bus Units to be reset.

When the settings (IP address or tag data link settings) of the EtherNet/IP Unit or built-in EtherNet/IP port are transferred from a Programming Device, all of the destination EtherNet/IP Units or built-in EtherNet/IP ports (nodes) will be reset in order to enable the transferred settings. Transfer settings to the EtherNet/IP Units or built-in EtherNet/IP ports only after verifying that restarting the Units will not cause any problems in the system.

If a repeater hub is used for EtherNet/IP tag data links (cyclic communications), the network's communications load will increase, data collisions will occur frequently, and stable communications will be impossible. Always use a switching hub when using tag data links in the network.

Before resetting a CPU Bus Unit or Special I/O Unit, always verify that restart the Unit will not cause any problems in the system.

EtherNet/IP System Configuration Example

EtherNet/IP is an industrial multi-vendor network that uses Ethernet components. The EtherNet/IP specifications are open standards managed by the ODVA (Open DeviceNet Vendor Association), just like DeviceNet.

EtherNet/IP is not just a network between controllers; it is also used as a field network. Since EtherNet/IP uses standard Ethernet technology, various gen- eral-purpose Ethernet devices can be used in the network. The EtherNet/IP Unit and built-in EtherNet/IP port have the following features.

The EtherNet/IP protocol supports implicit communications, which allows cyclic communications (called tag data links in this manual) with EtherNet/IP devices. Data can be exchanged at high speed between Controllers and devices, using high-volume tag sets (up to 640 words for the CJ2M and up to 184,832 words for other CPU Units) between PLCs.

Tag data links (cyclic communications) can operate at the cyclic period specified for each application, regardless of the number of nodes. Data is exchanged over the network at the refresh cycle set for each connection, so the communications refresh cycle will not increase even if the number of nodes is increased, i.e., the synchronicity of the connection’s data is preserved.

Since the refresh cycle can be set for each connection, each application can communicate at its ideal refresh cycle. For example, a processes interlocks can be transferred at high speed while the production commands and the status monitor information are transferred at low speed.

The communications load to the nodes must be within the Units’ allowed communications bandwidth.

Data can be exchanged with other OMRON FA devices using SEND, RECV, and CMND instructions from the ladder program, because EtherNet/IP supports OMRON’s standard FINS message communications services.

There are two kinds of message services, using UDP/IP and TCP/IP (called FINS/UDP and FINS/TCP), allowing flexible data exchange for different applications.

There are no particular restrictions when sending FINS messages to OMRON Ethernet Units (CS1W-ETN21 or CJ1W-ETN21) in an Ethernet network.

Mutual connections of Controller Link and EtherNet/IP are also supported (using the FINS communications service). The Controller Link connection allows a PLC on the Controller Link network to be monitored from a PLC on the EtherNet/IP network. Conversely, data can be exchanged with a PLC on the EtherNet/IP network from a PLC on the Controller Link network.

Functions

Note

A built-in FTP server is provided to enable transferring files in the PLC to and from a host computer. This enables transferring large amounts of data from a client without any additional ladder programming.

The clocks built into PLCs connected to Ethernet can be automatically adjusted to the time of the clock in the SNTP server. If all of the clocks in the system are automatically adjusted to the same time, time stamps can be used to analyze various production histories.

A separate SNTP server is necessary to automatically adjust the PLC clocks.

Internal status information from the EtherNet/IP Unit or built-in EtherNet/IP port can be passed to network management software that uses an SNMP manager.

A separate SNMP manager is necessary for network management.

DNS client functionality allows you to use host names instead of IP addresses to specify SNTP servers and SNMP managers. This is useful, for example, when server IP addresses change for system revisions because the IP addresses are automatically found when host names are used.

(1)A separate DNS server is necessary to use host names with the DNS client.

(2)The DNS server is specified directly using its IP address.

A subnet mask can be set to use classless IP addresses, allowing more flexibility in address settings.

A variety of functions are provided to quickly identify and handle errors.

Self-diagnosis at power ON

PING command to check the connection with another node

Error Log functions record the time of occurrence and other error details

The CIP (Common Industrial Protocol) is a shared industrial protocol for the OSI application layer. The CIP is used in networks such as EtherNet/IP, ControlNet, and DeviceNet. Data can be routed easily between networks that are based on the CIP, so a transparent network can be easily configured from the field device level to the host level.

The CIP has the following advantages.

Destination nodes are specified by a relative path, without fixed routing tables.

The CIP uses the producer/consumer model. Nodes in the network are arranged on the same level and it is possible to communicate with required devices whenever it is necessary.

The consumer node will receive data sent from a producer node when the connection ID in the packet indicates that the node requires the data. Since the producer can send the same data with the same characteristics in a multicast (either multicast or unicast can be selected), the time required for the transfer is fixed and not dependent on the number of consumer nodes.

1-3 Support Software Required to Construct a Network

Unit Setup: CX-

Programmer

This section describes the Support Software that is required to construct an EtherNet/IP network. Make the tag data link settings and Unit setup settings for the EtherNet/IP Unit or built-in EtherNet/IP port. Both of these settings are stored in the EtherNet/IP Unit’s non-volatile memory (See note.). Support Software is provided for each, as described below.

Note Unlike the Ethernet Units, the EtherNet/IP Unit’s TCP/IP settings are not stored in the CPU Unit’s CPU Bus Unit System Setup Area. The settings are stored in the EtherNet/IP Unit itself.

The CX-Programmer is used to set basic parameters, such as the local IP address of the EtherNet/IP Unit or built-in EtherNet/IP port and the subnet mask. (The CX-Programmer is included in the CX-One.)

The CX-Programmer can also be used to check if data I/O is being performed correctly for tag data links.

1-4 Communications Services Overview

The following communications services are supported.

CIP (Common Industrial Protocol) Communications Services

1) Tag Data Links (Cyclic Communications)

A program is not required to perform cyclic data exchanges with other devices in the EtherNet/IP network.

Normally, the tag data links in an EtherNet/IP Unit or built-in EtherNet/IP port are started by grouping the tags created with the Network Configurator into a tag set, and establishing a connection with the target device using that group of tags. One connection is used per group (tag set). Up to 32 connections for the CJ2M and up to 256 connections for other CPU Units) can be registered.

The following table gives the tag and tag set specifications.

Various control operations (such as the reading and writing of I/O memory between PLCs, mode changes, and file memory operations) can be executed from the host computer by sending the corresponding FINS command with a UDP/IP or TCP/IP header attached.

For example, it is possible to connect online via Ethernet from FINS communications applications such as the CX-Programmer, and to perform remote programming and monitoring. (See note.)

Note Use CX-Programmer version 4.0 to use TCP/IP. For lower versions of CX-Pro- grammer, FinsGateway Version 2003 or higher is required to use TCP/IP.

Network Configurator Overview

Section 1-5

1-5-3 Precautions When Using the Network Configurator

Only an OMRON EtherNet/IP Unit can be set as the originator for a connection using the Network Configurator.

The Network Configurator can be connected to the EtherNet/IP network through the following ports:

CS1/CJ1-series CPU Unit’s serial port (peripheral or RS-232C) or Ethernet port on EtherNet/IP Unit

CJ2-series CPU Unit’s serial port (USB or RS-232C), Ethernet port on EtherNet/IP Unit or built-in EtherNet/IP port

The Network Configurator can be connected directly to the EtherNet/IP network from the computer’s Ethernet port. When connecting directly to the EtherNet/IP network, an Ethernet port must be set up in the computer in advance. In this case, the Network Configurator will be connected to the EtherNet/IP network as a single node. If there isn’t an unused node address available, the Network Configurator can’t be connected directly to the EtherNet/IP network.

Note (1) In this case, pps means “packets per second” and indicates the number of packets that can be processed in one second.

(2)To use 505 to 1,444 bytes as the data size, the system must support the Large Forward Open standard (an optional CIP specification). The SYSMAC CS/CJ-series Units support this standard, but before connecting to nodes of other companies, confirm that those devices also support it.

(3)If the maximum data size is exceeded, the data refreshing with the CPU Unit will extend over two or more cycles.

(4)If status layout is selected in the user settings, the maximum number of tags that can be received is 19 tags.

(5)If parameters are changed in the EtherNet/IP Unit, however, the EtherNet/IP Unit will be restarted. When other nodes are communicating with the affected node, the communications will temporarily time out and automatically recover later.

(6)Because the EtherNet/IP Unit is equipped with an IGMP client (version 2), unnecessary multicast packets can be filtered by using a switching hub that supports IGMP snooping.

(7)The EtherNet/IP Unit uses the TCP/UDP port numbers shown in the following table.

Ethernet Address

Ethernet address (12 digits)

Note (1) The Ethernet Address can also be checked with the CONTROLLER DATA READ command. For details, refer to Appendix E FINS Commands Addressed to EtherNet/IP Units or Built-in EtherNet/IP Ports.

(2)An IP address label is included with the EtherNet/IP Unit, so the user can record the user-set IP address and subnet mask on the label, and affix the label to the front of the Unit. When this label is affixed to the front of the Unit, it is easy to confirm the Unit’s IP address and subnet mask.

Seven-segment Display When the power is turned ON (or the Unit is restarted), all of the segments will flash twice, the IP address set in the EtherNet/IP Unit or built-in EtherNet/IP port will be displayed on the 7-segment display just once, from right to left. Afterwards, the rightmost 8 bits of the IP address is displayed in hexadecimal during normal operation.

Example 1: Displaying IP Address 192.168.250.10

The IP address is displayed in decimal, flowing from right to left.

If the Unit is operating normally, the last digit of the

Unit's IP address is displayed in hexadecimal.

Flashing: The tag data link is stopped.

Lit: The tag data link is operating.
