DDE Overview
DDE is a method used by Microsoft Windows to accomplish
process-to-process communications. This common protocol allows a
DDE-compliant Windows application to communicate with another
DDE-compliant Windows application. DDE has been a part of
Windows since version 2.0 and is supported by many of the most
popular Windows application packages, such as MS Excel and MS
Word for Windows.
The implementation of DDE uses a data server (called the OCI data
server) to send and receive data from the CNC. This data server
provides a DDE interface so other DDE compliant Windows
applications can access data as though the CNC information was
from a local DDE device.
A DDE application must provide three pieces of information to
access a single piece of data from the OCI DDE data server:
• Service or Application name
• Topic name
• Item name
The service for your DDE application will be the Allen–Bradley OCI
DDE data server. The name for this service is:
ABOCISERVER
For the Allen-Bradley OCI data server, a topic is an ethernet alias for
a specific 9/Series CNC. Refer to your OCI Installation Guide for
details on establishing 9/Series ethernet topic names. This alias is
identified in the OCIDSCFG.INI file as the TopicId.
For 9/PC CNCs, the topic name is used to identify a 9/PC (located in
the host computer) to facilitate communication between the 9/PC
CNC executive and various client applications and services running
on a PC. TopicId for the 9/PC CNC is set in the Configuration
Manager.
An item is either a data item or a command item. Data items are
listed starting on page 4–1 and are used to read and write data
from/to your CNC. Command items are listed starting on page 5–1
and are used to request the 9/Series CNC perform a specific task.
