CitectSCADA uses the following methods
to exchange data:
exchange (DDE)A Microsoft Windows standard protocol set of
messages and guidelines that enables communication between Windows

CitectSCADA can act as
providing tag values to requesting clients
to request data from other applications.
connectivity (ODBC)Allows applications to access data in database
management systems using structured query language (SQL) to access
data., where CitectSCADA functions as an ODBC
server, allowing other applications to read CitectSCADA variables directly.
By using a common external database, where CitectSCADA and other applications use
the same database to store and share information.
