EMC Directives

OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.

EMC-relatedperformance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.

EtherNet/IP System Configuration Example

EtherNet/IP is an industrial multi-vendornetwork 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-purposeEthernet devices can be used in the network. The EtherNet/IP Unit andbuilt-inEtherNet/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-volumetag 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-ETN21orCJ1W-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-inFTP 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-inEtherNet/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-diagnosisat 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) 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-inEtherNet/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.

Note In this example, a connection is established with the originator’s tag list containing tags a to g (inputs), which are grouped in a tag set called SP1_IN, and the target’s tag list containing tags i and ii (outputs), which are grouped in a tag set called SP1_OUT.

2) Message Communications (Unconnected Message Service)

User-specifiedCIP commands can be sent to devices on the EtherNet/IP network. CIP commands, such as those for reading and writing data, can be sent and their responses received by executing the CMND instruction from the CS/CJ-seriesCPU Unit’s user program (without using a connection).

(EtherNet/IP)

Response

CIP messages (CIP commands and responses) can also be transferred to another CIP-basednetwork via the EtherNet/IP Unit orbuilt-inEtherNet/IP port using the CIP routing function for message communications.

In the CS/CJ Series, CIP routing is possible only through two EtherNet/IP Units or built-inEtherNet/IP port.

Communications

Service

FINS commands can be sent to or received from other PLCs or computers on the same Ethernet network by executing SEND(090), RECV(098), or CMND(490) instructions in the ladder diagram program. This enables various control operations such as the reading and writing of I/O memory between PLCs, mode changes, and file memory operations.

Note There are no particular restrictions when sending FINS messages to OMRON Ethernet Units(CS1W-ETN21orCJ1W-ETN21)in an Ethernet network.

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 UseCX-Programmerversion 4.0 to use TCP/IP. For lower versions ofCX-Pro-grammer, FinsGateway Version 2003 or higher is required to use TCP/IP.

Network Configurator Overview

Section 1-5

1-5-3Precautions 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-seriesCPU Unit’s serial port (peripheral orRS-232C)or Ethernet port on EtherNet/IP Unit

CJ2-seriesCPU Unit’s serial port (USB orRS-232C),Ethernet port on EtherNet/IP Unit orbuilt-inEtherNet/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.
