Release 2.0
With ‘DDE Client Points’ all data transfers or conversations are initiated by CX-Supervisor either
sending data to or requesting data from external DDE Server Application(s). For example, a CX-
Supervisor point could be linked to update a cell on a Microsoft Excel worksheet.
With ‘DDE Server Points’ all data transfers are initiated by external DDE Client Application(s) either
requesting or sending point values. For example, a value could be entered into a cell in Microsoft
Excel which would update a CX-Supervisor point.
DDE Client Points
A DDE client point sends data to or requests data from an external server application. This chapter
explains how to create points that make use of the CX-Supervisor DDE Client capabilities. In order
for data to be transferred between a point and a server application the point must uniquely identify the
application and the data that is to be used in the transfer. DDE applications use a three-tiered
identification system to distinguish themselves from other DDE applications. An
application name
is
at the top of the hierarchy, the application name refers to a server application e.g. “EXCEL”. A
topic
name
further defines a server application e.g. for Microsoft Excel the topic would define the
worksheet to be used e.g. “SHEET1.XLS”, a server can support one or more topics. Finally each
topic can have one or more
item names,
which uniquely
identifies a data item within a topic, i.e.
“R1C1” or a cell name reference identifies a single cell within a Microsoft Excel worksheet.
Example
A DDE Client point named “DDE1” that connects to Microsoft Excel, worksheet – “Sheet1.xls” and
cell “R1C1”, is created.
