Introduction

This document provides a “road map” for setting up a PointScan data acquisition system that is made up of the following elements:

1. PointScan/100 and PointScan/200 series hardware modules,

2. KEPServerEX server software.

3. DASYLab client software.

This document is called a “road map” because it provides top-level directions to guide the user through the setup process. Each software package (IOToolKit, KEPServerEX, and DASYLab) provides more detailed setup information through on-line help screens.

This road map is designed for users who have the following system configuration:

• Both the DASYLab and KEPServerEX software packages are running on the same computer.

• The computer and the PointScan modules are connected using an Ethernet LAN (Local Area

This document covers the setup process for two network cases, (1) “Dedicated” LAN and (2) “Shared” LAN. For most of the steps the instructions are identical. When differences do exist, the steps for each case are clearly indicated.

Be sure to follow the steps as applicable to your LAN. If you are uncertain as to whether the LAN is “Dedicated” or “Shared,” please consult your network administrator. The figures on the following two pages should clarify any confusion regarding the type of LAN (Dedicated or Shared).

which are configured using the IOToolKit software package.

Network).

“DEDICATED” LAN

“Dedicated” LAN refers to an Ethernet Local Area Network that is dedicated solely to the PointScan system and to no other device. The following 2 figures are examples of “Dedicated” LAN setups.

Dedicated LAN, with no HUB/Switch

Note: A “Crossover” Ethernet Cable is used in this setup.

Dedicated LAN, with Ethernet Hub/Switch

Note: Standard Ethernet Cables are used in this setup.

“SHARED” LAN

“Shared” LAN refers to an Ethernet Local Area Network that is used by both the PointScan system and at least one other non-PointScan device.

Shared LAN

Note: Standard Ethernet Cables are used in this setup.

PointScan Road Map 878395 3

Step 1) Hook up the PointScan Hardware

Follow the hardware instructions in the PointScan User Guides to set up the module bases and to connect sensors to PointScan units. If you do not have a copy of those documents, you can find PDF versions at our website: page until you see PointScan manuals.

Two very important hardware configuration steps are located in the PointScan/100 Series User’s Manual, p/n 1085-0901. The steps can be found on pages 1-2 and 2-1 of that manual, respectively.

(a) Connecting the operating power to the modules. (b) Connecting RS485 communications wiring between multiple modules.

If you are connecting your computer directly to a single PointScan/100 module, you need to use an Ethernet crossover cable (instead of a standard one). If you have more than one /100 series PointScan module in your system, you will need to use an Ethernet hub or switch to connect the computer and PointScan hardware to the network.

If you have any PointScan/200 series modules in your system, you must have a PointScan/440 module to configure them. If this is the case, connect the 440 module to your computer’s serial port.

Never add PointScan modules to an active system, which is communicating with KEPServer. Prior to adding modules, power-down the on-line modules and stop the KEPServer communications.

Up to 7 PointScan modules can be powered by one PointScan/443 power supply module. Each PointScan module requires approximately 140ma of current from the power source. You will need to budget your available supply power accordingly, especially if you plan on using the same power supply for external transducers and/or current loops.

Whenever an un-powered PointScan/443 module is plugged-in, it will only power up to 4 connected modules. Attempting to startup more than 4 modules will result in a power-stall condition, in which the /443 module cannot produce a high enough output voltage. However, there are two methods for powering up more than 4 modules. Both are discussed in step 2, below.

Avoid unnecessary power cycling of PointScan systems, as these systems are designed to receive a continuous, uninterrupted supply of power. Returning power to a system of 5, 6, or 7 modules will likely result in a power-stall condition. Refer to the following step in regard to power start up.

Up to 32 modules using RS485 communications can be daisy chained from the RS485 port of one /100 series module. The /100 series modules provide the connection to Ethernet.

http://www.iotech.com/manuals.html. Simply scroll down the tech manuals

4 878395 PointScan Road Map

Step 2) Power up the PointScan Hardware

Up to 7 PointScan modules can be powered from one PointScan/443. However, the same is not true for system startup. Plugging in a PointScan/443 that supports 5, 6, or 7 modules will most likely result in a power-stall condition. If your system has 5 or more modules you will need to employ one of the following methods to power up the entire system.

Method 1 - uses a power output switch: (a) Ensure that the PointScan/443 is removed from its AC power supply. (b) Place an on/off switch in the /443’s 24 VDC power output line. (c) With the switch open [and up to 7 modules connected] supply AC power to the /443. (d) After the /443 is powered, close the 24 VDC power output switch. (e) Check the LEDs on the modules to verify their status is normal.

Method 2 - does not make use of a switch: (a) Ensure that the PointScan/443 is removed from its AC power supply. (b) Ensure that no more than 4 modules are connected to the system. (c) Plug the /443 into its AC power supply. (d) Check the LEDs on the modules to verify their status is normal. (e) If applicable, connect the additional module(s) one at a time. Make sure that no more

than 7 modules will be connected to a single PointScan/443.

(f) Check the LEDs on the newly added modules to verify their status is normal. Status LEDs are detailed in the PointScan hardware User’s Manuals.

PointScan Road Map 878395 5

Step 3) Set up Ethernet communications between your Computer

and the “Ethernet-Connected” PointScan/100 module(s)

PointScan/100 modules can be used in either an “Ethernet-connected” mode or an “RS-485 connected” mode.

In this step each PointScan/100 module discussed is used in the “Ethernet-connected” mode.

Determine the IP addresses for PointScan/100 modules

By default, the PointScan/100 modules are shipped with an IP (Internet Protocol) address of 10.1.0.1. This address is stored in the base of the /100 module. If your system has only one of these /100 modules and you have a direct connection from the computer to the /100 module, there is no need to change this IP address. However, if you have more than one PointScan/100 module take action according to whether your LAN system is “dedicated” or “shared.”

“DEDICATED” LAN “SHARED” LAN

For “Dedicated” LAN systems: If you have more than one “Ethernet-connected” PointScan /100 series module, you will have to change the IP address of the second and following modules to 10.1.0.2, 10.1.0.3, and so forth.

See Step 6, part g on Configuring /100 Series modules using IOToolKit.

For “Shared” LAN systems: You must obtain a set of unused IP addresses from your network administrator. Then you must change the IP address of each “Ethernet-connected” PointScan /100 series module to one of these unused addresses.

See Step 6, part g on Configuring /100 Series modules using IOToolKit.

Set up the IP address for your computer

Your computer’s IP address needs to be fixed, not a dynamic one chosen by DHCP or other means. To set this fixed address to one that is compatible with the PointScan/100 modules:

1) Open the Windows Control Panel and double-click the Network icon.

2) Navigate to the TCP/IP Properties window for the Network Interface card you are using.

3) Select the option labeled “Use the following IP address.”

4) Enter the following numbers for “Dedicated” or “Shared” LAN, as applicable to your system:

“DEDICATED” LAN “SHARED” LAN

IP Address: 10.0.0.1 Subnet Mask: 255.0.0.0

Use an IP Address and Subnet Mask provided by the network administrator.

6 878395 PointScan Road Map

5) Close out the Network window and the Control Panel. Make sure that you disable any firewall programs or other software that might restrict traffic on the Ethernet port.

Screens Pertaining to Internet Protocol

IP Address and Subnet Mask shown are for a “Dedicated” LAN. For ”Shared” LAN obtain IP Address and Subnet Mask values from your network administrator.

Step 4) Install the IOToolKit Software

(a) Insert the IOToolKit CD (p/n 1075-0601) into the CD drive on your computer. If the CD does not

auto-start use Windows Explorer to browse to the contents of your CD drive. Then, open the IO Tools Install folder and double-click on the Setup.exe file [in that folder].

(b) Follow the prompts to complete the installation.

At some point after the installation you need to register your IOToolkit software. This is done from the IOToolkit Help>Registration Window.

PointScan Road Map 878395 7

Step 5) Start up the IOToolKit Software

Start the IOToolKit by going to the Windows Start menu and then selecting Programs > IO Tools. The IOToolKit is used to set up the configuration of each PointScan module in the system. It also

downloads the configuration to the module base.

Step 6) Configure each Ethernet [PointScan/100 Series] Module

using IOToolKit

Most of the IOToolKit windows have a Help button you can press if you are not sure how to select some of the parameters.

(a) Start the configuration process by running the Plug and Play Wizard in IOToolKit. You do this by

selecting Tools, then Plug and Play Wizard; or by clicking on the Playing Card icon. (b) Select <Add a new station to the project> and click <OK>. (c) Select the type of module to be added. Note that the PointScan/100 series modules are all of the

Ethernet I/O Module type. (d) If this is the first module you are adding to the project, IOToolKit will ask you to save the

configuration as a Project File. Select a file name (use the extension *.6pj) and click <Save> to

save the project file away.

TIP: Perform the File/Save Project action several times during the configuration process to ensure the project is saved with your most recent configuration settings.

(e) Fill in the parameters in the General tab, then click <Next>:

Station type – Select the PointScan/100 series module being used. Station name – Any alphanumeric string up to 20 characters can be used. Serial number – use the serial number printed on the front of the base of the /100 series

module, just above the power wiring.

Station number – start with number 1, then increment for other stations in the system,

whether /100 or /200 level stations. It is very important that the station number is set correctly when you have multiple modules interconnected using RS485. The station number must correspond with the number that represents the module’s position in the RS485 link. The first module that connects to Ethernet is always station one, and each additional module that is connected using RS485 takes the next consecutive station number in order.

Com timeout – 3 seconds is usually adequate (click on Help for more info)

• Click on <OK> when you are done.

• Select <Specify an IP address>. Since the

system is part of a shared LAN network you will need to change the module’s IP address to an unused one [provided by your network administrator].

• Enter the IP address [provided by your network administrator].

• Primary Protocol - select Modbus

• Advanced Settings - click on this button,

then enter a subnet mask number which was provided by your network administrator.Leave all other parameters at their default values.

• Click on <OK> when you are done.

(h) Fill in the blanks in the Discrete or Analog tab, then click <Finish>. Some points of importance pertaining to PointScan/100 Series systems:

Which tab is used [Discrete or Analog] depends on the type of /100 series module that

you are configuring.

For information on how to set the parameters, click on the <Help> button. Disable all unused channels. You can select a unique tag name for each channel. These tag names will be used by

KEPServer and DASYLab to identify the channels when creating your final program.

Do not change the I/O address. This is the standard addressing scheme used by the

Modbus protocol. These addresses will be used by KEPServer to access the data from the PointScan modules.

Each PointScan module can have different selections under the “features” column. Refer to

your specific type of PointScan module for available features. You can select or change any available features on a per channel basis.

The Range column can be set on a per channel basis. Pick the measurement range that is

best suited for your particular application.

Some PointScan modules are capable of several different scan rate settings. You can select

the module scan rate setting that is most appropriate for your application. It is recommended that you select the same scan rate for all modules in your system. You should configure the modules for the fastest sample rate that you ever expect to need and then you can use a method in DASYLab to discard readings to effectively create a lower sample rate for the modules of your choice.

Scaling is typically done using KEPServer or DASYLab. You should not make any changes

under the Scaling Parameter tab in IOToolKit.

It is important to note that all thermocouple inputs are in Engineering Units (EU) of degrees Celsius or Fahrenheit, depending on the “Temperature Reporting” selection. If you select 0.1°C or 0.1°F the reading generated by the module will be a whole number 10 times greater than the actual value. If this is the case you will need to scale down the value by a factor of 10 in KEPServer or DASYLab.

All voltage and current inputs are in raw A/D converter counts. Therefore, the voltage and current inputs must be scaled to Engineering Units in KEPServer or DASYLab by converting them to floating point numbers.

Step 7) Configure each “RS-485 Connected” Module using IOToolKit

Two “RS-485 Connected” and One “Ethernet-Connected” Module

Providing one cluster of channels over the internet via a single IP Address

An “RS-485 connected” PointScan module can be a /200 Series or a /100 Series module. In both cases “RS-485 connected” modules serve as expansion devices for the “Ethernet-connected” PointScan/100 module which resides at the head of the RS-485 link (see preceding figure).

From software and communication viewpoints, the entire set of modules appears as one cluster of channels, accessible over the Ethernet via a single IP Address.

To configure the “RS-485 connected” modules:

(a) Start the configuration process by running the Plug and Play Wizard in IOToolKit. You do this by

selecting Tools, then Plug and Play Wizard; or by clicking on the Playing Card icon. (b) Select <Add a new station to the project> and click <OK>. (c) Select the type of module to be added. Select “RS-485 I/O Module type” regardless of whether

the module is a /200 series or /100 series [in RS-485 mode]. (d) Fill in the parameters on the General tab [in the Remote I/O Configuration window]

then click <Next>:

• Station type – Select the PointScan/100 or /200 series module being used.

• Station name – Any alphanumeric string up to 20 characters can be used.

• Serial number – use the serial number on the base of the /100 or /200 series module.

• Station number – must be a unique number in the total PointScan system. It is very

important that the station number is set correctly when you have multiple modules interconnected using RS485. The station number must correspond with the number that represents the module’s position in the RS485 link. The first module that connects to Ethernet is always station one, and each additional module that is connected using RS485 takes the next consecutive station number in order.

You can download the configuration to the /100 series modules using the Ethernet connection between the computer and the modules. However, keep in mind that you can connect only module at a time to the network when you are downloading configuration information to that module.

In both instances, i.e., for “dedicated” and “shared” networks: a) Click on the Ethernet Device icon. b) Go to Device/Select (or click on the Select Device icon). c) Ensure the parameters are set as follows:

o Use Ethernet

o Connection = Network/Passthru

o Timeout = 3000 mS

o IP Address: Use “Specify an IP Address” and enter the current IP Address for the station. If

you want to change the IP Address you need to enter the new address in the module configuration as described in Step 6g.

one /100 series

Each PointScan/100 module has a factory default IP Address of 10.1.0.1. If you have changed that address, e.g., during a configuration download, then you will have to enter that new address. If you are not sure as to what the new address is, you can use the “Find Ethernet Status” utility [binoculars icon] to learn what the current IP Address is.

Step 10) Install the KEPServerEX Software

Note: If you have purchased the LITE version of KEPServer you will be allowed to configure your

server to communicate with up to a maximum of 4 PointScan modules.

After you purchased the KEPServerEX software license, you should have received a green Kepware CD that is packaged inside a green and gold plastic container. There should be a Kepware software license number and an IOTech PointScan /100 license number printed on the inside front cover of the plastic container. Also, the plastic container should include a 16-page product information booklet that tells you how to install the KEPServer license. Read pages one through four for detailed installation instructions. These instructions can be summarized as follows:

(a) Insert the Kepware CD into the CD drive on your computer. This needs to be the same PC

that will be connected to the PointScan modules and will be running DASYLab. Note: Inserting the CD should auto-start the installation process. If the CD does not auto-

start, use Windows Explorer to browse to the contents of your CD drive. Then, find the KEPServerEX_Install \ Disk1 folder on the CD and double-click on the Setup.exe file [in that folder].

(b) Follow the prompts to complete the installation.

Note: Make sure that you select

installation. Do not select all drivers or you may run into problems later on.

only the IOtech PointScan100 driver when you do the

booklet and follow the instructions for Licensing and Registering a Driver.

Until you register the driver you will not be able to run KEPServer for more than 2 hours.

20 878395 PointScan Road Map

Step 11) Start up the KEPServerEX Software

The KEPServerEX software is used to set up and implement an OPC server. This server automatically polls the PointScan modules and updates its data base with the current value of the process variables monitored by those modules. Information in that data base can then be accessed by compatible OPC clients, such as DASYLab or Kepware’s Quick Client.

General information on KEPServerEX is available on the Kepware CD. Insert the CD in the drive and let it auto-start as described in Step 10). Then click on the “Product Specifications” menu item and select KEPServerEX from the list. The system will show you several pages of general information about the features and operation of KEPServerEX.

For more detailed instructions on configuring KEPServerEX, close out the Product Specifications window and click on the Menu button to bring up the first menu on the Kepware CD. Click on the “Product Support” selection and you will see several useful documents, including a Quick Start Guide, an Installation Guide, and a KEPServerEX Help Manual under the White Papers option.

To start up and run the KEPServerEX software, go to the Windows Start menu, select the KepWare Products program group, and then click on KEPServerEX.

The following steps show how to configure KEPServerEX specifically for PointScan/100 and /200 type modules. They include information on how to:

• add station names and channel tag names

• specify device IP addresses and channel Modbus addresses

• prove the IO communication with all devices using the OPC <QuickClient> button

• save the configuration for backup purposes

Note: In any of the KEPServerEX configuration windows, you can always click on the

<Help> button for more information on how to fill out the forms.

Step 12) Configure KEPServerEX

Adding a KEPServerEX “Channel”

The first step in the configuration process is to create a new KEPServerEX “Channel.” Note that the word “channel” in this context means a communications channel or driver, not a process input such as a thermocouple input or voltage input channel. The steps are:

(a) Click on the “Click to add a channel” link in the upper left hand portion of the

KEPServerEX window.

(b) In the “New Channel - Identification” window either accept the default channel name, or

enter a new one, then click on <Next>. Note that the name must not exceed 256 characters.

TIP: Change the name to something other than “channel.” A meaningful channel name will stop confusion from occurring when accessing the actual channel tags through DASYLab. A good idea is to use a project name, for example, “Test_Lab_Monitor.”

/100” device driver is selected. Then click on Next.

If the IOtech PointScan100 driver is not listed in the pulldown menu, there has been an installation error. If this is the case you must uninstall and reinstall the KEPServerEX software, taking care to include the IOtech PointScan100 driver in the installation.

(d) In the “New Channel - Network Interface” window, you can leave the selection at

“Default” if you have only one network interface card (NIC) installed in your computer. If you have multiple NICs installed, you must select the NIC that communicates with the PointScan hardware in your system. Then click on Next.

(e) In the “New Channel - Write Optimizations” window, you can accept all of the default

parameters and click on Next.

(f) In the “New Channel - Summary” window, review the information for correctness and then

click on Finish.

(g) Select File>Save As to create a KEPServerEX project file for your current system.

Adding a KEPServerEX Device

In KEPServerEX, a “device” is a single PointScan module (either a PoinScan/100 series device or a PointScan/200 series device). The steps for adding a device to a KEPServer “channel” are as follows:

(a) Click on the “New Device” button in the upper left hand portion of the KEPServerEX

window. See following figure.

Clicking on the “New Device” Button

(b) In the “New Device - Name” window, enter a device name that follows the stated

guidelines and then click on Next.

If the device is a /100 series PointScan module that is connected to the Ethernet,

enter the IP address of the module that you configured in IOToolKit. Example for “Dedicated” LAN: 10.1.0.1 Example for “Shared” LAN: 63.66.249.202

In both the “Dedicated” and “Shared” LAN examples, the PointScan/100 series module was configured as Station 1 in IOToolKit.

If the device is a /200 series PointScan module [or a /100 series module

connected via RS485 communications], enter the IP address of the /100 series Ethernet module to which it is connected, followed by a decimal point and the device station number of the module that you configured in IOToolKit

Example for “Dedicated” LAN: 10.1.0.1.2 Example for “Shared” LAN: 63.66.249.202.2 In both the “Dedicated” and “Shared” LAN examples, the “.2” signifies that the

PointScan module is station number 2 in a string of modules connected via RS485.

(d) In the “New Device - Communication Parameters” window, accept the default parameters

and click on <Next>.

(e) In the “New Device - TCP/IP” window, accept the default port number and click on

<Next>.

(f) In the “New Device - Block Sizes” window, accept the default parameters and click on

<Next>.

(g) In the “New Device - Summary” window, review the information for correctness and then

click on <Finish>.

Adding a KEPServerEX Static Tag

In KEPServerEX, a “static tag” represents a single input to a PointScan module (either a PoinScan/100 series device or a PointScan/200 series device).

Note: The word “tag” is frequently used in the industrial automation and control industries and is

common terminology with OPC server software packages.

TIP: Since, each tag applies to one specific input [or output] that is connected to a PointScan module, think of each tag as a “per-channel” text name.

The steps for adding a static tag to a KEPServer device are:

(a) Click on the “Click to add a static tag” link in the upper right hand portion of the

KEPServerEX window.

(b) In the General tab section of the “Tag Properties” window (next figure), fill in the

parameters for the first tag as follows:

Tag Properties, General Tab

Name - Any alphanumeric string up to 256 characters can be used. However, you should keep

the names as short as possible since they must fit in various displays. It is important to give each

channel a name that will allow you to recognize it in DASYLab and know which physical input or

output signal channel it represents on the PointScan module. You should take the time to plan out

a naming scheme that will allow you to easily identify channels by their tag names. This is

especially important for systems that have large channel counts.

To automatically create new tag names use the KEPServerEX “duplicate tag” utility. To use this feature end the tag name with a number.

24 878395 PointScan Road Map

Address - Click on the <?> (Hints) button and then the Hints window’s <Help> button for

detailed information on how to set the address. The IOtech PointScan hardware manuals provide detailed MODBUS addressing information for each individual module type. For example, the screen indicates that for Analog input you would use addresses in the range 300001 to 330000; and for Discrete input you would use addresses in the range 100001 to 200000. The IOtech PointScan modules use standard MODBUS addressing for I/O; however, KEPServer requires that an additional (0) zero be placed in the MODBUS addressing scheme. The KEPServer address is a factor of 10 higher than the standard MODBUS address for that I/O type and channel.

Example: The MODBUS address of the third analog input channel on a PointScan /100 series

module is 30003. You will enter 300003 as the address for that tag in KEPServer.

The tag address must be unique within each PointScan module. So if you have a second PointScan module with analog inputs, you would start over again with address 300001.

Description - This is a comment field (not required). Any alphanumeric string up to 64 characters

can be used.

Data Type - If the OPC client is DASYLab, then the process variables in KEPServer must be

configured for short data format, since DASYLab can recognize

only the short data format.

Client Access - If the tag is an analog or digital input, then Client Access should be set to Read-

Only. If the tag is an analog or digital output, then Client Access should be set to Read/Write.

Scan Rate - Leave this parameter at the default value of 100 milliseconds. This represents an

optimized system in which KEPServer will poll data from the PointScan modules as fast as possible and DASYLab can be used to control which data points are processed and which data points are thrown away.

Note: It is possible to apply scaling to your data from within DASYLab using DASYLab’s own scaling

module. If you prefer to perform this operation in DASYLab you can disregard the settings under the scaling tab in KEPServer.

can find the raw data ranges in the IOToolKit project configured earlier. Note: The ranges are located in the Scaling tab in the IOToolKit project. The project

is located under the analog or discrete setup screen. IOToolKit’s Scaling tab shows the raw minimum (Low) and raw maximum (High) values for PointScan outputs. The same values are to be placed in the Low and High fields under the KEPServer Scaling tab. This is true for each tag you are configuring.

The values for the Raw Range (see figure at right) are obtained from the IOToolKit project, which was previously configured.

Tag Properties, Scaling Tab

c.4 After you have entered all of the parameters in the General and Scaling windows for

the first tag, click on the <Apply> button at the bottom of the window.

c.5 Enter parameters for additional tags in one of two ways:

Click on the “New” tag icon to save the previous tag information and bring up blank fields for the next tag.

Running the “Quick Client” Program

Kepware provides a program called “Quick Client” to allow you to test the configuration and make sure that KEPServerEX can communicate with the PointScan modules and gather valid data. To run Quick Client, do the following:

(a) In the KEPServerEX main window, either select Tools>Launch OPC QuickClient or click on

the Quick Client icon (looks like a hammer) at the right end of the icons in the toolbar.

(b) In the OPC Quick Client window, highlight one of the PointScan devices in the upper left

hand part of the window. Note that the entries with a “_System” at the end of their label are

not actual devices but are system entities. So don’t highlight them.

hand part of the window. Each row of information represents a single tag in the selected device. The Item ID column shows the associated name of each tag. The Quality column for each tag should read “Good” if KEPServerEX is communicating properly with the selected device. Also, the Value column should display the correct current value of the input associated with that tag. Remember that if you have chosen KEPServer, the raw readings will not have a decimal point shown in the display.

OPC Quick Client

You should highlight each device in sequence, checking to make sure that the Quality and Value parameters for each tag are legitimate. If they are not, you will need to review the setup windows for each problem device and tag in KEPServerEX to find the source of the problem.

(d) After you are done running Quick Client, use File>Exit to close out the program. You do

not need to save the changes to the Quick Client program because you will run a fresh version of this test program each time.

Step 13) Configure DASYLab as the Client Program

Install DASYLab

DASYLab software versions that precede 6.0 do not support

PointScan products. If your DASYLab version precedes 6.0, please contact

For DASYLab to properly install, the host computer must be using

Internet Explorer version 5.0 or higher.

Install DASYLab as follows:

(a) Launch the DASYLab installation from the DASYLab CD.

Note: The CD should auto-start. If the CD does not auto-start, run the CD start.exe

from the Windows Desktop. (b) Select “Installation,” then “Full Version.” The actual installation process will begin. (c) When prompted for your name, company and serial number, enter the requested data.

Obtain the serial number from the CD jacket.

TIP: Keep the serial number in a safe place. You may need to reference it for future installations and upgrades.

(d) When prompted for the installation directory and program folder, you can use the default

selection, or choose another. We recommend using the default.

(e) When prompted for Setup Type, choose from the available options. We recommend

that you select Typical.

(f) When prompted to select the drivers, “uncheck” all selections, then click <Next>.

There are no PointScan related drivers to select. The drivers that are selected in step 6 are for components that are in addition to PointScan.

Connect DASYLab to the OPC Server

Before connecting DASYLab to the OPC Server, use KepServer’s Quick Client feature to verify that the OPC server is receiving valid readings from the PointScan device. A discussion of Quick Client begins on page 27.

Complete the following steps to connect DASYLab to the server.

1. From a DASYLab worksheet, access the DataSocket Import Setup screen by navigating as follows from the toolbar (see the following left-hand figure):

⇒ Modules [pull-down menu]

⇒ Network

⇒ DataSocket Import (left-click to bring up a DataSocket Import Icon)

Double-click on the DataSocket Import Icon (not shown) to open the

DataSocket Import Setup dialog box (see the following right-hand figure).

Selecting DataSocket Import

2. Click on the triangular add button [item 2 in the above figure] to add the desired number of channels. Each click of the button will sequentially place a socket image beneath a channel. In the preceding figure socket images can be seen for channels 0, 1, 2, and 3.

Note: If your system has more than 16 channels, you will need to put an additional

DataSocket Import module on your worksheet.

3. Configure a channel; steps 3(a) through (f).

DataSocket Import Setup

3(a) Select the channel that is to be configured. Note that a green socket indicates the

channel for which selected options will be applied. In the previous figure, channel

0 is selected. 3(b) For the connection Type, select OPC. 3(c) Click on the <Select Item> button.

DASYLab will search the computer registries and list every OPC server program

that resides on your computer. 3(d) Locate and expand the OPC Server Software identifier (see following figure). In

the figure we selected KEPware.KEPServerEx for the Kepware OPC Server

Software. In addition, we expanded Channel 1 to show PointScan104 and its

associated tags (Temp1 and Temp2); as well as PointScan204 (not shown in its

entirety) to show its associated channel tags (Temp3 and Temp4). You would

need to scroll down to see Temp3 and Temp4.

Expanding the Server Item

3(e) From the expanded list, select the channel tag that applies to the channel

currently being configured.

In our example tags will be assigned to channels as follows:

PointScan104 / Temp1: Channel 0

PointScan104 / Temp2: Channel 1

PointScan204 / Temp3: Channel 2

PointScan204 / Temp4: Channel 3

3(f) For the channel that is being configured, select the desired “tag” by

p 3(h)

highlighting it; then click <OK>.

3(g) Click the <Options> button (following figure). The Data Socket Import

Options box will open.

Enter the time value for the Scan Rate. Ste

Click the <Options> button to open the DataSocket Import Options box. Step 3(g).

3(h) Enter the time value for the scan rate and Click <OK>. The resulting scan

rate, i.e., data return per unit time, is what we want DASYLab to use for the PointScan device.

The previous figure indicates that we want to have data returned every 0.1000 seconds, (10 samples/sec). Note that the time factor entered here will later be entered in the Experiment Setup window [step 9, page 34].

4. Repeat step 3 for each of the remaining channels. Continue with step 5 after all channels have been configured.

5. Click the <Save> button and save your setup under an appropriate filename and location.

6. Close the DataSocket Import Setup box.

7. From the Experiment pull-down menu, select Experiment Setup.

An Experiment Setup box will appear (following figure)

Setting Block Size and Scan Rate in Experiment Setup

PointScan Road Map 878395 33

8. In the Experiment Setup window, in the Global Settings frame (see above figure), verify that Auto Select is unchecked and that the Block Size is set to 1.

9. In the Global Settings frame, under Sampling Rate/Ch, set the time value to the match the value that was specified in the DataSocket Import Options box [step 3(h), page 33]. Set the units to Sec. The resulting scan rate, i.e., data return per unit time, is for data to be returned once every 0.1000 seconds. This is equal to 10 samples/sec.

For each DASYLab worksheet module in the Experiment Setup window, set the Block Size and the Sampling Rate to match that of the first module. This will ensure that the data from each worksheet module coincides with the data from the DataSocket Import module.

10. Close the Experiment Setup window.

11. From the Module pull-down menu, select Display, then select an appropriate display module. This will allow you to see the data after the play button is clicked.

This completes the procedure for configuring DASYLab for PointScan.
