Intouch Overview
Wonderware’s InTouch 7.0 is a Windows PC based supervisory HMI development package
included with Wonderware’s Factory Suite 2000 software package. InTouch enables rapid
development of graphical monitor and control applications that interact with a versatile offering of
DDE based I/O servers. InTouch uses three integrated applications that perform the following
functions.
InTouch Application Manager
- Is used to create, manage, and select HMI application
projects.
InTouch WindowMaker
- Is the devleopment environment used to create HMI applications.
InTouch WindowViewer
- Is the runtime environment for applications created in
WindowMaker
.
Normally, the HMI application developer runs the 
InTouch
Application Manager to setup the
framework for the application, and then spends their time in the 
WindowMaker
and
WindowViewer
applications as the custom HMI is developed in iterative steps.
In InTouch, the tag dictionary is central to the operation of the application. The tag dictionary is a
high performance database that is used to connect application data to graphic objects using
animation links. The graphic objects provide the user’s view to a system. There are four basic tag
data types:
