Rockwell Automation 8520-9API 9/Series OCI API Developer's Guide - Manual (Page 16)

1–7 Open Control Interface (OCI) Overview
Publication 8520-6.6 - August 1999
Many development tools are available to enhance your machine
interface as well as document machine statistics, etc. This manual is
written assuming the use of Microsoft’s Visual Basic
t development
tool.
When we developed the basic display set we took advantage of
several special development tools to simplify development and
improve performance of our application.
RSLinx JBOX and RSData.OCX
The basic display set was developed using a sub–set of Rockwell
Softwares RSTools
t development kit. This development tool
provides many custom controls that will improve the look of your
final application as well as enhance performance.
The basic display set makes extensive use of the RSData.OCX
custom control. This control is used in place of standard windows
DDE text transfers for most of the data links to the OCI data server.
This custom OCX dramatically improves the speed at which DDE
data is transferred.
Included with the basic display set package is the JBOX.DLL which
is required to allow this custom control to function. You must
include this DLL with any OCI software you ship that uses the basic
display set.
Included with the API development package is a subset of RSTools
called RSData which provides the custom OCX control to add to
your visual basic development tool and the JBox.DLL necessary to
make this application work.
Refer to your RSData user’s guide for details.
