Your application program is your DDE–compliant
Microsoft-Windows
t based application. This application provides
the interface between your personal computer and the OCI data
server. The application can range from the more complex, such as a
compiled Microsoft Visual Basic
t executable which can provide the
entire operator interface to your 9/Series or 9/PC, to a simple
Microsoft-Excel
t spread sheet with only a few DDE calls used for
data collection.
The Basic Display Set included with the OCI package is an example
of a DDE compliant application program. The basic display set is a
compiled visual basic program and is discussed later in this manual.
The visual basic source code for these default screens is available as
an option through your Allen-Bradley sales office.
