| CyboCon software supports standard DDE and Network
DDE interface. Dynamic data exchange (DDE) is a mechanism
supported by Microsoft Windows operating systems that
allows two programs to “talk” to each other
by continuously exchanging data.
CyboCon supports both the DDE Server and the DDE Client.
A DDE Source Application (or Server) provides data to
a Destination Application (or Client). The configuration
for conversation is done in the Destination Application.
CyboCon and most HMI packages can be either the Server
or Client. When a Client begins a DDE conversation with
the Source Application, it must specify the following:
- Application: The name of the Server.
- Topic: The subject of the conversation.
- Item: The content that allows the DDE to interface
to the Server.
Using DDE, CyboCon can be easily setup to talk to a
DDE Client or DDE Server such as Microsoft Excel software.
Due to the nature of the DDE interface that does not
have robust data handshaking capabilities, it is recommended
that DDE not be used as the primary interface method
in MFA control applications that involve mission critical
processes or equipment. On the other hand, DDE/NetDDE
are still suitable for training, testing, lab, and simulation
environment because of its ease of use and low cost.
