1-2 OPC and Its Technology OPC is the abbreviation of OLE for Process Control. It was created by a group of automation leading companies and Microsoft. They established the OPC Foundation to create the standard interface for the automation software in the automation fields. Because

Most of the software is running in Microsoft windows operating system, in this reason, OPC Foundation use OLE structure to let the programmers to integrate the software in the Windows software. Using standard COM, DCOM, ActiveX technologies, programmers could establish the integration software easily. They could develop the software fast and do not have to do the same work in different kind of HMI environment or different kind of computer language. In the beginning, the OPC Foundation presents OPC Data Access Specification. It used in the OPC version 1.0 and OPC version 2.0. The newest version of OPC Specification is OPC version 3.0. OPC version 3.0 which not only includes the Data Access Specification, but also include OPC Alarms & Events, OPC Batch, OPC Data eXchange, OPC Historical Data Access, OPC Security and OPC XML functions. In most of

Overview OPCTechs OPC Server User Guide

the cases in the automation fields, OPC Data Access function is most popular.

1-3 OPC Foundations The OPC Foundation is dedicated to ensuring interoperability in automation by

creating and maintaining open specifications that standardize the communication of acquired process data, alarm and event records, historical data, and batch data to multi-vendor enterprise systems and between production devices. Production devices include sensors, instruments, PLCs, RTUs, DCSs, HMIs, historians, trending subsystems, alarm subsystems, and more as used in the process industry, manufacturing, and in acquiring and transporting oil, gas, and minerals.

1-4 Benefits of OPC Save Client developer’s time: Client site developers do not have to deal with driver

development, The OPC Server provider will provide it. Save driver developer’s time: For Save the effort and time of the programmers, using

the OPC Server will be the best policy. Interoperability of OS: In the standard OPC interface, even if we use the different kind

of operating system. It could be integrated easily. It was impossible that numerous devices simultaneously communicate to a single

central system. Now, with OPC Server, this is no more a mission impossible. Interoperability of OPC client applications: After applying OPC technology, it is very

easy to integrate different kinds of OPC client applications. Look for more information: http：//www.opcfoundation.org/

5-1-4 XML Export The Configurator also allows you to export data from your configuration database to an

XML file. The XML export/import functionality was mainly developed for Windows platforms that do not support databases (e.g. Windows CE and Windows Embedded). XML has the following advantages over the CSV import/export function:

XML has a standardized format, unlike the text/CSV format, which uses various delimiters. (E.g. TAB instead of commas, strings could not accept all characters, etc.)

XML is language-independent, whereas CSV converts date/time, floats, and currency fields according to local settings in Windows. For example, using CSV, you cannot export data on German Windows and import it on English windows without making changes.

Windows has an installed automation object that has the capability to work with XML. Thus, programmers can create/modify their configurations outside the Configurator using Visual Basic, if desired.

XML supports schemas. A schema is a special XML file that specifies the data structure of an XML data file. To export data, select XML Export from the File menu. This opens the Export XML

File dialog box, as shown in the figure below. Give the file a name, and then choose the directory to which you want to export the data from your database. Click Save. Note: You can also export configuration data to an XML Scheme file by selecting XML Export from the File menu.

5-1-6 XML Import The Configurator allows you to import data from your configuration database to an XML

file. The XML export/import functionality was mainly developed for Windows platforms that do not support databases (e.g. Windows CE and Windows Embedded). XML has the following advantages over the CSV import/export function: • XML has a standardized format, unlike the text/CSV format, which uses various

delimiters (e.g. TAB instead of commas, strings could not accept all characters, etc.) • XML is language-independent, whereas CSV converts date/time, floats, and currency

fields according to local settings in Windows. For example, using CSV, you cannot export data on German Windows and import it on English windows without making changes

• Windows has an installed automation object that has the capability to work with XML.

Thus, programmers can create/modify their configurations outside the Configurator using Visual Basic, if desired.

• XML supports schemas. A schema is a special XML file that specifies the data

structure of an XML data file. To import data, select XML Import from the File menu. This opens the Import XML File

dialog box, as shown in the figure below. Give the file a name, and then choose the directory from which you want to import the data. You can then specify the delimiters and choose from the following import settings. Click Open.

• Create new items. When the import file contains items that are not yet in the

configuration database, then it creates them. Otherwise it skips these items. • Update existing items. When the import file contains items that are in the configuration

database, then it updates them using data from the import file. Otherwise it skips these items.

Either Create new items or Update existing items must be selected. Otherwise there is

nothing to import.


43

Select the .XML file to be imported.

XML file Import succeeds


44

5-1-7 XML Validate Selecting XML Validate from the File menu does not import an XML data file, but it will

try to validate its structure using stored XML schema. Once it passes this validation, the XML file is acceptable for import by the Configurator.

Select the XML file to be validated


45

Validate succeed.

Database dialog box. Open OPC Trace toolbar

5-5-1 Options Selecting Options from the Tools menu opens the Options dialog box. The

General tab of the Options dialog box, shown below, contains the following options

Parameters setting: • Save regional setting in registry :

Checking this option allows you to save regional settings in the registry so that they are applied each time you start the configuration application. This applies to the language settings as well as time and date settings.

• Automatically apply changes when selection is changed : Checking this option allows changes to the configuration database to be saved each time you switch dialogs without clicking on the Apply button or being shown a message asking if you would like to apply changes.

• Enable hover selection : Checking this option allows you to highlight an item by moving the mouse pointer over that item and keeping it there for a specified amount of time (in milliseconds)

• Monitor view setting Update Rate :


49

This specifies the update frequency (in milliseconds) of the items in the Monitor View. The monitor scans the server and displays the tag values at the bottom of the Configurator screen.

The OPC Configurator and OPC Server are two independent programs. As the OPC Server was connected by one of the OPC Client program, and then you on line modify the parameters in the OPC Configurator. You got to wait for about a few seconds to update the OPC server

5-5-2 Compact/Repair MS Access Database You can compact Microsoft Access databases, which can be either configuration

databases or historical databases, using the Compact/Repair MS Access Database dialog box, shown in the figure below. To open this dialog box, select Compact/Repair MS Access Database from the Tools menu. Microsoft Access–based databases are subject to database fragmentation over time, and the support for the database will compact the target database, reclaim unused space, and drastically improve database performance. Please make sure all OPC Clients are not connected when using this function. It is critical that no users or client applications are connected to the database at the time of compacting and that, if the Backup Original Database option is selected, there is plenty of available hard disk space.

6-1 Address Space Please read every PLC OPC Server users manual.

6-2 Conversations You can tell the OPC server to convert the data value by setting the [Conversion]

properties. The system provides Default Linear, Default Square Root and None (to/from float) three types of the formula. Besides, users could add the new user defined formula as you want. Look at the figure below.

Item Description Name Specifies the name of the conversion definition. The name can be

up to 12 alphanumeric characters, including underscores ( _ ) and hyphens ( - )

Type of Conversation Conversion Type: For each conversion definition, select one of the following conversion types from the drop-down list:

No (make float)：Converts the data into float data type, but does not change the value itself. When this option is selected, the Engineering Units and Instrument Range fields are disabled.

Linear：Keeps a linear relation between EU and IR. Square Root：Keeps a square root relation between EU and

6-3 Device Parameters The Device Parameters directory contains the list of custom device types. Device

parameters influence the behavior and performance of the server for the device. The meaning of numbers in the device parameters dialog, shown below, is the

maximum amount of data that can be transferred in one message. Setting the value that equals to zero forces the server to use single read/write messages only.

Select [Device Parameters] from the Tree View, open one of the sub-entries, the picture below should appear. Or right click for the Popup menu to appear, select [New] [Device Parameters] to add a new entry.

Item Description Name Specifies a unique device parameters name of the conversion

definition. The name can be up to 12 alphanumeric characters, including underscores ( _ ) and hyphens ( - )

Read It means the number of data items (tag) from continuous addresses is able to communicate in one Message. If the value is 0, it means only one data item (tag) can be communicated at once.

Write This set value means the number of signal points from continuous addresses able to communicate in one Message. If the value is 0 means only one signal point can communicate at one time.

Word swap When the data type is DINT, UDINT, Float, it switches the first and second word. The value takes 2 bytes, it is calculated from upper and


57

lower bits, because Intel CPU’s and Motorola CPU’s have reversed combination of upper and lower bits, Word Swap is used

Swap bits Reverses the order of bits in word-sized values (least significant bit becomes the most significant bit).

6-4 Simulation signals The Configuration offers various OPC data items in the Simulation Signals tree control,

as shown in the figure below. Users could define the different kind of simulation formula. To test the client functionality, choose a Simulation Signal from the Signal drop-down list, as shown for the data item below. All levels in the Address Space folder support the process of simulation. The parent list in the tree control is superior; it has higher priority when deciding to simulate the data item or not.

Item Descriptions Name Specifies a unique name of the selected simulation signal. The name

can be up to 12 alphanumeric characters, including underscores (_) and hyphens (-).

Type For each signal, you can select one of the following signal types from the drop-down list:

Read count is incremented by one every time when the item is read.

Write count increments when the item is written.


58

Random generates random value within the Amplitude range starting with Position.

Ramp, Sine, Square, Triangle and Step are periodical signals. Their time behavior is influenced by Period and Phase parameters. Period specifies the signal frequency (in milliseconds), while Phase moves the signal origin on the time axis (in degrees).

Square and Triangle have one additional parameter: Ratio defines Triangle signal steepness, or Square signal H/L

proportions. The # of steps parameter of the Step signal defines a number of

steps signal amplitude will be divided into. Parameters Position：start value

Amplitude：Amplitude Period(ms)：counting periods Phase (deg)：the calculation degrees. Ratio：ratio value # of step：number of counting steps

6-5 Alarm Definitions Alarm definitions are divided into two alarm template types－ Digital alarm

definitions and Limit (analog) alarm definitions. Digital alarms can be defined for Logical data items, while Limit alarms can be defined for Numeric data types.

6-5-1 Limit Alarm A limit alarm sets the values for four levels of alarms: Low, Low, High, and High High.

Limit alarm parameters can have sub ranges within the data item amplitude. Every sub range definition includes a Message Body that will be appended to the alarm message, the Severity of the alarm, and the Req. Ack. flag for alarm acknowledgement. The following graph shows the Limit Alarm.

Item Description Name Specifies a unique new limit alarm name of the selected simulation

signal. The name can be up to 12 alphanumeric characters, including underscores (_) and hyphens (-).

Update Rate Defines the frequency of checking the data item value (in milliseconds), and possibly responding by sending the alarm message

Dead band Dead band prevents the server from generating a huge amount of


66

alarm messages and overloading the clients when the signal oscillates around one of the limits specified. The dead band value extends the limit zone. It results in sending only one alarm message even if the signal oscillates

Limit Alarm Definition

It supports the following alarm types High High, High, Lo, LoLo

Value：The Value field is used to calculate the state of the input fields. For example, a value of 10 for LoLo is compared with the value of the input to determine if the alarm is in LowLow state.

Message Body：In the Message Body field, enter the warning message that will appear when the alarm is sent. The message can be any text string.

Severity：is the OPC-defined value for alarm Priority. The valid OPC severity range is 0 (lowest) to 1000 (highest).

Req Ack：This field is used for OPC condition alarms to determine whether the alarm needs a user acknowledgement. If the Requires Ack field is checked, then the alarm requires a user acknowledgement. If the value is not checked, then the alarm is posted as already acknowledged

Apply Saves all changes specified in the properties dialog box. Reset Undo the setting configuration Add New Add the new Alarm Definition

Users could get the alarm status like True/False, Message Body and Severity.

To make the current database active, select Make Active from the File menu. A dialog box appears showing both the current active database and database that is currently being edited, as shown in the figure below. To set the edited database as the active database, click the Yes button. Next time the server goes into runtime, it will use this active database for all of its operations.


78

7-6 Templates Template function allows you to set a group of data items as many template modules.

As the template is formed, users can only define the Port, Device and Group. Pick up one of the Template in every group; it could save you a lot of time and easy to maintain the system. There are two types of Template models we present. One is Simple Template, the other is Parameterized Template. We will introduce them in the following sections.

7-6-1 Simple Templates The function is used for a great deal of same equipments with the same

communication memory address which should be integrated into OPC server. In the traditional way, we will create many devices in OPC Server. Each of the devices should create the same data items. It will waste you a lot of time to add, delete or modify the data items for each device. With the template function, modify the data items in the Template; all of the data items in each device will be changed. (Please refer to the following example)

Users can choose the proper template and correspond to the Group definition. The OPC server will follow the template data items definition for communication when the OPC Server is revoked.


79

Operation Steps: Move the cursor to Templates Edit New Simple Template Folder

The first default Simple Template name is “New_Simple_Template”. Please modify it and choose Apply to save a new template name.


80

Then add data items into the template. Menu Edit New Date Item. Look for more information about data item definition, please read every PLC OPC Server users manual. The steps are as follows:

Add new data items. The following sample shows data items of Voltage, Current and Power.


81

Defines a Port with four Devices and specify their station number as 1, 2 , 3 and 4. Then defines a Folder for each deviece. After creating a new Folder, enable the Template checkbox and choose New_Simple_Template.

Defines a Port as the following figure.


82

Defines four Devices and specify their station number as 1, 2 , 3 and 4.


83

Defines a Folder for each deviece. After creating a new Folder, enable the Template checkbox and choose Simple Template. From the template Combo box, choose a proper data items template into this group.

Apply the setting and go to the File in the menu bar and choose Make Active to active the current database. File Make Active


84

Check the communication status steps. (Template function could only be checked by the OPC Client software) Move the cursor to Start Program Files OPCTechs OPCTechsSampleClient OPCTechsSampleOPCClient to startup the program. Choose the Modbus OPC server and select the data items you want to monitor. Observe the values of the data items, you can tell the values are correct or not.

Connection succeeds.


85

7-6-2 Parameterized Templates The function is used for plenty of same equipments with the same data sources.

Each of the data sources with 4-20 mA or 0-10V signals should be integrated into PLC with a regular interval of memory addresses. In this situation, it’s suitable to use the Parameterized Template function to establish the data items. With the template function, modify the data items in the Template; all of the data items in each device will be changed. (Please refer to the following example for Modicon PLC) In this case, there are more than 20 smoke detectors should be integrated into OPC server. Each of the smoke detector provides nine 4-20mA signals. We can put the first smoke detector signals into Modicon PLC address 40001 – 40010, the second smoke detector PLC address will be 40011 – 40020, and so forth the last smoke detector PLC address should be 40190 – 40200. In this case, we can easily use the Parameterized Template to complete the data item definition. At first, define the Port、Device and Folder. In the Folder definition, choose Parameterized Template and select the template you defined. Put 0, 10, 20 …190 for the following groups in starting base address field.

Modicon PLC


86

Operation Steps: Move the cursor to Templates Edit New Parameterized Template Folder


87

The first default Parameterized Template Folder name is “New_Parameterized_Template”. Please modify it and choose Apply to save a new template name.

(Suppose the starting address is from 1 to 10) Add data items into the template. Menu Edit New Date Item.


88

Create a Port, Device and choose one of the Parameterized Template toy defined. Then set up the [offset] as 1, 10, 20 and 30. The steps are as follows:


89

After creating a new Folder, enable the Template checkbox and choose Parameterized Template. From the Template Combo box, choose a proper data items template into this group. (There are 10 tags in each folder. The starting address will be specified by the following rule. In temp_1 would be 1 to 10, in temp_2 would be 11 to 20… in temp_4 would be 31 to 40.)

Apply the setting and go to the File in the menu bar and choose Make Active to active the current database. File Make Active


90

Check the communication status steps. (Template function could only be checked by the OPC Client software) Move the cursor to Start Program Files OPCTechs OPCTechsSampleClient OPCTechsSampleOPCClient to startup the program. Choose the Modbus OPC server and select the data items you want to monitor. Observe the values of the data items, you can tell the values are correct or not.
