Topic update rate found in many DDE only servers. The valid range is 0 to 99999990 milliseconds. The default is
0 milliseconds. When set to 0 milliseconds the server will observe the DDE scan rate set at the individual tag
level using the Tag Properties dialog.
Once the desired path has been selected and the DDE scan rate has been set, click OK to complete the alias. To enter
more alias map elements, return to the Alias Map dialog.
Designing a Project
Although this server is designed for easy usage, there are several steps required to create, configure and run a project.
Utilize the server's User Interface to build a project, starting by selecting the specific communications driver,
configuring its parameters and then adding user-defined tags as necessary. Before beginning, refer to
The following steps provide guidance on the process of building a project. Throughout this example, a number of
additional help links will be presented in order to provide supplemental information. Use the Back button on the help
system's toolbar to return to the example. Select a link below to jump to a specific page.

Adding and Configuring a Device
Note: The examples in the following pages use the Simulator driver supplied with the server. The Simulator driver is a
memory-based driver that provides both static and changing data for demonstration purposes. The Simulator driver
does not have the broad range of configuration options found in many other communication drivers; thus, some
examples may require additional screen shots to demonstrate specific product features that are present when using one
of the normal communication drivers. In these cases, screen shots will be provided.
Running the Server
Although this server runs as a service by default, users can choose to run it on the desktop. When running as a service,
the server is online all the time. When running as a desktop application, the OPC client can automatically invoke the
server when it attempts to connect and collect data. In order for either process to occur correctly, users must first
create and configure a project. When invoked, the server automatically selects the most recently used project.
Initially, however, users need to manually invoke the server using the desktop icon, the Windows Start menu or by
selecting Configuration in Administration on the System Tray. The image below displays the invoked interface
(although its appearance may differ depending on any changes that may have been made). For more information on
the Configuration's elements, refer to
