About ScanServer
ScanServer is a Microsoft Windows (95/98 & NT) application that acts as a DDE Server
and/or OPC (OLE for Process Control) to allow other Windows applications to access
measurement data from TempScan, MultiScan, NetScan and ChartScan instruments.
ScanServer supports all Windows DDE and OPC Client applications, including
Wonderware’s InTouch, Rockwell Software’s RSView, Microsoft’s Excel, and
Visual Basic.

Getting Started
Reference Note: To set up NetScan, TempScan, MultiScan or ChartScan
hardware, refer to the setup and installation sections of the corresponding user's
manual.
Reference Note: A Net232 Ethernet/RS-232 Converter is required for TempScan,
MultiScan and ChartScan Ethernet Applications. The Net232 User’s Guide
(p/n 1037-0901) contains Ethernet-related information pertaining to these data
acquisition systems.
Installing ScanServer
The ScanServer disks include the ScanServer program files and a simple DDE Client
application useful in testing and troubleshooting DDE communications. Complete the
following steps to install ScanServer on the computer hard drive:
Note: The following steps are for installing from disks. If your ScanSever program is on
a CD-ROM, simply install the CD-ROM and follow the installation screen
prompts.
1. Close all currently running Windows applications.
2. Insert ScanServer disk 1 in your floppy drive.
3. Choose Start/Run (or File/Run from Program Manager).
4. In the dialog box, type a:setup.exe (b:setup.exe if installing from the b drive).
5. Choose OK and follow the on-screen instructions.
6. ScanServer will install to the directory you specify during installation. The
default directory is:
c:\Program Files\ScanServer
Quick Start
After you have installed ScanServer on your system, you must set up communication with
the TempScan, MultiScan, NetScan, or ChartScan instrument(s) attached to your system.
To do this, follow the procedures for:
1. Starting ScanServer.
2. Creating a node.
3. Configuring channels.
4. Saving the project.
5. Testing a nod e using the provided DDE Client.

Items
Item Types
ScanServer supports both strings and numeric data types for returning data.
Numeric items, indicated by a # preceding the item name, return a float or integer value
for the data item retrieved. For example,
String items, indicated by a $ preceding the item name, return data in formated ASCII
strings. For example,
Note: Items not preceded with a # or $, default to numeric items.
Array data items return 2 or more String or Numeric data items. Channels may be
indicated with commas separating them, with an inclusive dash between them, or with
both. For example:
Another example:
#last1 returns: 23.752 to the client in a 4-byte floating-point variable,
if 23.752 degrees is read on channel 1.
$last1 returns: 23.752 to the client as above but now in a 7-byte ASCII
string.
last1,3 returns two numeric data items, 23.752 and 24.567, assuming 23.752
degrees is read on channel 1 and 24.567 is read on
channel 3.
$last1-3 returns three string data items, 23.752, 24.111 and 24.567.
In addition,
#last1-3,5 returns four numeric data items: 23.752, 24.111, 24.567and 25.333

Procedures
1. Start Microsoft Excel.
Note: In Excel, DDE information must be entered in the following format:
=application|topicname!item
2. Enter the following in any empty cell:
=ScanServer|ts1!last1
where ts1 is the node name you entered when you created the node.
3. Press ENTER. Data from channel 1 should be displayed as an alphanumeric
string in the cell.
4. Now create an array by selecting six adjacent cells in any column.
Note: In Excel, arrays of DDE information must be entered by selecting the same
number of cells as channels to be read, entering =application|topicname!’item’,
and then pressing CTRL-SHIFT_ENTER to execute the command.

Using DDE Client with ScanServer
Introduction
The DDE Client application is provided as a quick and convenient way of verifying that
ScanServer software is configured properly; and that the data acquisition devices are
connected correctly to your system.
Note: DDE Client is for configuration verification only. It is not a data collection or data
analysis application.
Procedures
Start DDE Client
Start the DDE client application from the “Start” menu.
Connect to ScanServer and a Topic
Connect the DDE client to the ScanServer via the Connect item in the DDE menu.
Note: The ScanServer “Node” name is used for the DDE “Topic” name.
ScanServer User's Guide Using DDE Client with ScanServer 33
Start a Transaction
DDE transactions are started via the Start Transaction item in the DDE menu.
Several types of transactions are supported. The “Advise” type is commonly used to
establish a “Hot Link” with the ScanServer. Alternately the “Request” type may be
used to establish a “Warn Link” with the server.
Note: ScanServer does not support Execute type transactions.
Poke a Value
The DDE client supports sending data to the ScanServer via the Poke type
transaction. Using this type of transaction, a user may set an output bit on an
instrument.
34 Using DDE Client with ScanServer ScanServer User's Guide
When a Poke transaction is selected, the DDE client then asks for the data to be sent
to the selected item, in this case a “1” is sent to output bit 1.
Abandon a transaction
Abandon transaction is used to terminate a previously established “Advise” or
“Hot Link” transaction.
