1,200 would be converted to One Thousand - Twelve Hundred if converted using English metrics, but would be
One and Two-Tenths if converted using German metrics. Thus, if German software is running on an English OS,
users need to determine how the comma will be handled. This setting allows for such flexibility. By default, and
due to historical implementation, the server respects the Locale ID of the operating system.
DDE Options
While the server is first and foremost an OPC server, there are still a number of applications that require Dynamic
Data Exchange (DDE) to share data. The server provides access to DDE applications that support one of the following
DDE formats: CF_Text, XL_Table and Advanced DDE. CF_Text and XL_Table are standard DDE formats developed
by Microsoft for use with all DDE aware applications. Advanced DDE is a high performance format supported by a
number of client applications specific to the industrial market.
Important: In order for the DDE interface to work with the Runtime, the Process Mode parameter must be set to
Interactive. For more information, refer to
Runtime Settings - Runtime Process .
DDE Option Dialog
The DDE Option dialog, which allows users to determine how the server provides DDE data, can be reached by clicking
File | Project Properties | DDE in the server. Its parameters can be used to tailor the DDE operation to fit the
application's needs.
Enable DDE Connections to the Server
This parameter determines whether the DDE server portion of the server will be enabled or disabled. If DDE operation
is disabled, the server will not respond to any request for DDE data. If intending to use the server only as an OPC
server, users may want to disable DDE operation. Doing so can increase the data's security and improve the server's
overall performance. DDE is disabled by default. See Also:

Enable Net DDE
This parameter determines whether Microsoft's Net DDE services will be enabled or disabled. If intending to use the
server only with local DDE client applications, users should keep Net DDE disabled (the default setting). Starting the Net
DDE services can be a time consuming process that can slow the startup of the server. If users do need to use Net
