CHAPTER 1

Introduction

This chapter provides you with an overview of the KLINKMANN OMRON Ethernet Direct

DAServer, including the application- and bus-level communications protocols, item

naming conventions and DAServer features.

Overview

The KLINKMANN OMRON Ethernet Direct DAServer (hereafter referred to as the

“OMRON Ethernet DAServer” or “DAServer” or “DASOmronEth” throughout the

remainder of this user’s guide) is a Microsoft ® Windows ® application program that acts

as a FINS message communications protocol server. It allows other Windows application

programs access to data from OMRON PLCs (also referred to as devices) over the

OMRON Ethernet FA (Factory Automation) network.

The OMRON Ethernet Direct DAServer requires an Ethernet card and TCP/IP protocol

installed on the computer to communicate with the Ethernet network. The OMRON

Ethernet Direct DAServer can access to data from Controllers connected to the Ethernet

System directly (with Ethernet Unit installed) or from Controllers interconnected to

Ethernet System through SYSMAC LINK network or any other OMRON FA network

(through PC Gateway - an OMRON Controller which has multiple Communications Units

mounted, including the Ethernet Unit, and therefore that belongs to two networks and can

thus function as an interface between them). The OMRON Ethernet Direct DAServer

supports the Controller Memory Areas accessible by FINS commands.

No additions to Controller’s user program are needed if OMRON Ethernet Direct

DAServer is used in a poll (normal) mode, i.e. the DAServer sends read or write FINS

command to Controller and Controller responds with corresponding response. The

OMRON Ethernet Direct DAServer supports also the possibility to receive “unsolicited”

data from Controller – in this case some additions in Controller program are needed. The

DAServer “slave” mode can be established – at communication start-up DAServer

requests data one time and after it - only unsolicited data can be received from Controller.

At same time the writing of new values to Controller is still possible.

The OMRON Ethernet Direct DAServer can access to data from CS1/CJ1, CV-series and

C200HX/C200HG/C200HE PLCs (directly from Ethernet network or inter-networked from

other OMRON FA networks) as well as from C-series and CQM1 PLCs (only inter-

networked from other OMRON FA networks).

While the OMRON Ethernet Direct DAServer is primarily intended for use with

Wonderware InTouch ® (Version 7.11 Patch 02 and later), it may be used by any

Klinkmann Automation Omron Ethernet DAServer 3

Omron Ethernet DAServer Ver 1.x User Manual Rev 1.4 17014m14

Microsoft Windows program capable of acting as a DDE, SuiteLink ™ or OPC client that

can also coexist with FactorySuite ™ 2000 and greater.

Communication Protocols

The OMRON Ethernet Direct DAServer communicates with clients and PLCs using the

following different communications protocols:

• Application communications protocols such as OPC, DDE and SuiteLink to

communicate with clients located on either local or remote nodes.

• FINS message communications protocol to communicate with the Omron controllers

over FA (Factory Automation) networks.

Important! This DAServer is compliant with the OPC Data Access (DA) 2.05

specification.

For more information about the DAServer architecture, see the Reference section.

Application Communications Protocols

The DAServer utilizes the following application communications protocols to

communicate with the clients.

OPC

OPC (OLE for Process Control) is a non-proprietary set of standard interfaces based

upon Microsoft’s OLE/COM technology. This standard makes possible interoperability

between automation/control applications, field systems/devices and business/office

applications.

Avoiding the traditional requirement of software/application developers to write custom

drivers to exchange data with field devices, OPC defines a common, high-performance

interface that permits this work to be done once, and then easily reused by HMI, SCADA,

control and custom applications. Over the network, OPC uses DCOM (Distributed COM)

for remote communications.

SuiteLink

SuiteLink uses a TCP/IP-based protocol and is designed specifically to meet industrial

needs such as data integrity, high throughput, and easier diagnostics. This TCP/IP

standard is supported on Windows NT and Windows NT-technology-based operating

systems (for example, Windows NT, Windows 2000, and Windows XP).

SuiteLink is not a replacement for DDE, FastDDE, or NetDDE. The protocol used

between a client and a server depends on your network connections and configurations.

SuiteLink provides the following features:

• Value Time Quality (VTQ) places a time stamp and quality indicator on all data values

delivered to VTQ-aware clients.

• Extensive diagnostics of the data throughput, server loading, computer resource

consumption, and network transport are made accessible through the operating system’s

performance monitor. This feature is critical for the operation and maintenance of

distributed industrial networks.

• Consistent high data volumes can be maintained between applications regardless if the

applications are on a single node or distributed over a large node count.

• The network transport protocol is TCP/IP using Microsoft’s standard WinSock interface.

Klinkmann Automation Omron Ethernet DAServer 4

Omron Ethernet DAServer Ver 1.x User Manual Rev 1.4 17014m14

FastDDE

FastDDE provides a means of packing many proprietary Wonderware Dynamic Data

Exchange messages into a single Microsoft DDE message. This packing improves

efficiency and performance by reducing the total number of DDE transactions required

between a client and a server.

Although Wonderware's FastDDE has extended the usefulness of DDE for our industry,

this extension is being pushed to its performance constraints in distributed environments.

DDE

DDE is a communications protocol developed by Microsoft to allow applications in the

Windows environment to send/receive data and instructions to/from each other. It

implements a Client/Server relationship between two concurrently running applications.

The server application provides the data and accepts requests from any other application

interested in its data. Requesting applications are called clients. Some applications such

as InTouch and Microsoft Excel can simultaneously be both a client and a server.

NetDDE

NetDDE is a communications protocol that extends the standard DDE functionality to

include communications over local area networks and through serial ports. Network

extensions are available to allow DDE links between applications running on different

computers connected via networks or modems.

For example, NetDDE supports DDE between applications running on IBM-compatible

computers connected via LAN or modem, and DDE-aware applications running on non-

IBM-compatible computers under operating environments such as VMS and UNIX.

FINS Message Communication

The FINS Messages system is developed by OMRON for its Factory Automation

networks. FINS Communications allow PLCs on these networks to be controlled by

reading and/or writing memory area data without the need to program these operations

into the controller’s user program.

Accessing Items via the DAServer

The method for accessing items through the DAServer depends on the communications

protocol being used.

OPC

In the case of OPC communications, the protocol addresses an element of data in a

conversation with six characteristics: node name, program name, group name, device

group, link name, and item name.

• The node name (required for remote access) and device group are optional.

• A fully qualified OPC Item name (ItemID) is composed of the link name and item name.

• All other characteristics are specified through separate DAServer means.

Klinkmann Automation Omron Ethernet DAServer 5

Omron Ethernet DAServer Ver 1.x User Manual Rev 1.4 17014m14

To access an OPC item, the OPC client needs to connect to the DAServer (either in-

process or out-of-process) and create an OPC group defining the data-acquisition

properties for the collection of items to be added. OPC groups

can be either public or private. Public OPC groups are shared across multiple clients,

whereas private OPC groups are local to a single client. Optionally, a device group, which

indicates the access path to the items for read/write, can

be specified from the DAServer.

The following briefly describes each characteristic of the OPC protocol:

• node name: Computer (host) name identifying a specific node on the network (for

Remote Access ONLY).

• program name: The registered OPC server name uniquely identifying a specific server

(ProgID). For this DAServer, the program name is ArchestrA.OmronEth.1.

• group name: The OPC group created from the client for organizing a collection of items

logically with the same data acquisition properties between the client and the server, such

as update rate.

• device group: Meaningful names configured in the DAServer under a specific controller

for the common custom attributes between the DAServer and the device, such as update

interval. If not specified from the client, the default device group using the global

configuration attribute values from the DAServer is assumed. Functionally, a device group

is equivalent to an access path (optional).

• link name: The set of hierarchy node names, representing the specific devices on a

communications path link from the hierarchy root to a specific controller as configured for

this DAServer under the DAServer Manager, separated by delimiters.

• item name: A specific data element, the leaf of the hierarchy tree of this DAServer,

within the specified group. For example, when using this DAServer, an item can be a

relay, timer, counter, register, and so on, in the controller.

DDE/SuiteLink

In the case of DDE/SuiteLink communications, the protocol addresses an element of data

in a conversation that uses a four-part naming convention that includes the node name,

application name, topic name, and item name. The fully qualified DDE/SuiteLink naming

convention includes all four parts, although the node name part (required for remote

access only) is optional. The following briefly describes each portion of this naming

convention:

• node name: Computer (host) name identifying a specific node on the network (for

Remote Access ONLY).

• application name: The name of the Windows program (this DAServer) that will be

accessing the data element. In the case of data coming from or going to the Modicon

devices via the DDE/SuiteLink PlugIn of this DAServer, the application name portion of

the address is DASOmronEth.

Klinkmann Automation Omron Ethernet DAServer 6

Omron Ethernet DAServer Ver 1.x User Manual Rev 1.4 17014m14

• topic name: Meaningful names are configured in the DAServer to identify specific

devices. These names are then used as the topic names in all conversations with that

device. For example, OmronPLC. Topic name maps to a device group defined in the

DAServer.

Note: You can define multiple device-group (topic) names for the same device (PLC) to

poll different points at different rates.

• item name: A specific data element within the specified topic. For example, when using

this DAServer, an item can be a relay, timer, counter, register, and so on, in the PLC.

Note: The term "point" is used interchangeably with the term "item" in this user's guide.

For more information on item/point names, see the Item Names section of this user's

guide.

Features

The KLINKMANN OMRON Ethernet Direct DAServer provides the following features:

• The ability to communicate over multiple application-level protocols at the same time.

• The ability to add new application-level protocols on the fly.

• The ability to be configured remotely.

• New, robust diagnostic abilities.

For more in-depth information on the DAServer architecture, see the Reference section.

Demo Mode

Demo Mode allows you to test the functionality of the OMRON Ethernet Direct DAServer

(with all features enabled) for 60 minutes. To use OMRON Ethernet Direct DAServer in

unlimited mode, the HASP key or Software License Key is needed.

The HASP key is the USB or parallel key (dongle) to be installed into PC USB or parallel

port and needs the HASP Device Driver to be installed on same computer. The Software

License Key is16-character alphanumeric “computer-dependent” string, provided after

purchasing the OMRON Ethernet Direct DAServer (for more information, see “Enabling

Software License Key for DASOmronEth” section later in this manual.

Without HASP key installed or Software License Key entered, the OMRON Ethernet

Direct DAServer will run 1-hour in demo mode with all features supported - after 1-hour

DAServer stops the updating read/write on all device items and will reject the addition of

any new items, but connected Clients can continue to function normally (for example, you

can still add or remove an item, but its value is not updated).

After purchasing the OMRON Ethernet Direct DAServer, the appropriate HASP key or

Software License Key is provided and no re-installation of DASOmronEth is needed.

Notes:

1. Unlike the previous OMRON Ethernet Direct DAServer versions (up to v1.18), the

HASP Device Driver should be installed separately – as its installation is not included and

not performed during the OMRON Ethernet Direct DAServer setup. The HASP Device

Preparing the Hardware to be used with OMRON Ethernet

DAServer

The Omron Ethernet DAServer requires an Ethernet card and TCP/IP protocol supporting

Windows Sockets interface to be installed on the computer to communicate with the

OMRON PLCs over the Ethernet network.

Each connected OMRON Controller (with Ethernet Unit installed) must be configured to

allow it to function as a node on the Ethernet network. This setup can be done by

switches on the module and/or appropriate programming software.

The OMRON C200HX/C200HG/C200HE PLCs (except CPU11), CV-series PLCs, CS1

PLCs as well as CJ1 PLCs can be used as nodes on Ethernet network. The

C200HX/C200HG/C200HE PLCs must be supplied with communication module:

C200HW-PCS01-EV1 Ethernet Set or C200HW-PCU01 PC Card Unit supplied with the

Ethernet PC Card (e.g. Kingston T.C. EtheRxEthernet PC Card models: KNE-PCM/M –

for coaxial and twisted pair connection, KNE-PCM/T – for twisted pair connection).

The CS1-series PLCs must be supplied with CS1W-ETN01 Ethernet Unit.

The CJ1-series PLCs must be supplied with CJ1W-ETN11 Ethernet Unit.

The CV-series PLCs must be supplied with CV500-ETN01 communication module.

The Ethernet PC Card installed in the C200HW-PCU01 PC Card Unit in the

C200HX/C200HG/C200HE PLC is configured by software supplied with communication

hardware.

Node number and Unit number of CV500-ETN01 (in CV-series PLC) is set by rotary

switches on the module. Software (CVSS software, SYSWIN or CX-Programmer) is used

to configure IP Address, Routing tables and IP Address tables.

Node number and Unit number of CS1W-ETN01 Ethernet Unit (in CS1-series PLC) is set

by rotary switches on the front side of module. Local IP Address is set by switches SW1,

SW2, ..., SW8 on the back side of module. Software (CX-Programmer) is used to

configure Routing tables and IP Address tables.

Node number and Unit number of CJ1W-ETN11 Ethernet Unit (in CJ1-series PLC) is set

by rotary switches on the front side of module. Software (CX-Programmer) is used to

configure Routing tables, local IP Address and IP Address tables.
