About This Manual
The BridgeVIEW User Manual contains the information you need to get
started with the BridgeVIEW software package. This manual explains the
BridgeVIEW environment, tag configuration, human machine interfaces,
alarms and events, and historical data logging and extraction. This manual
also reviews the concepts of G programming.
Throughout both sections of this manual, there are activities that teach
you what you need to know to build your own virtual instruments, and
ultimately, your own SCADA system. This manual assumes that you
know how to operate your computer and that you are familiar with its
operating system.
Organization of This Manual
This manual is divided into two parts. Part I, BridgeVIEW Concepts,
introduces you to the basic BridgeVIEW concepts, and includes Chapters 1
through 8. Part II, G Tutorial, describes the G programming language, and
how it works within BridgeVIEW, and includes Chapters 9 through 15.
We encourage you to work through all the activities in this manual before
you begin building your applications. You should save all of the VIs you
create with the BridgeVIEW activities in the
BridgeVIEW\Activity
directory. To view the VI(s) for an activity that you have not completed
yourself, see the
BridgeVIEW\Activity\Solutions
directory for the
solutions to the activities from the BridgeVIEW Concepts section of this
manual, and the
BridgeVIEW\Activity\Solution
directory for the
solutions to the activities in the G Tutorial section of this manual.
BridgeVIEW Concepts
Part I, BridgeVIEW Concepts, contains the following chapters.
• Chapter 1, Introduction, describes the unique BridgeVIEW approach
to Human Machine Interface (HMI) and Supervisory Control and
Data Acquisition (SCADA). It also contains system configuration,
installation instructions and basic information that explains how
to start using BridgeVIEW to develop industrial automation
applications.
• Chapter 2, BridgeVIEW Environment, describes the BridgeVIEW
environment. It explains the basic concepts behind G, the
