The Java Edition of the GLG Toolkit
web-enables process control and mission-critical applications by using
client-side Java. With the Java
edition, an application can deploy dynamic HMI screens on the web,
allowing the operator to control and
monitor the process in a web browser, with no local installation
required. It may also be used to create a cross-platform Java-based desktop
applications for mission-critical control and monitoring.
run-time class library can be easily
integrated into existing SCADA applications, making it an ideal
tool for developing custom HMI and
For a mobile deployment where Java is not available, the Mobile Edition of the Toolkit can
Point and Click
The Java Edition
the GLG Toolkit includes the GLG
Builder - a graphical editor with point and
click interface for creating dynamic
HMI and SCADA screens and
diagrams. With the Graphics Builder, developers can create
control and system monitoring drawings, define dynamic behavior
and attach real-time data
sources. A large number of pre-built components and palettes are available
for use as building blocks in the Builder. An optional GIS Map component is also available.
The HMI screens
use vector graphics and are resolution-independent,
makes it possible to deploy them on a wide range of displays - from large monitors to mobile devices.
created with the
Builder can be reused between all deployment platforms - C/C++/C#,
Java, .NET, Web and Mobile.
Desktop or Web Deployment
The Java Edition
also includes the GLG Java Class Library, which is
used at run time. The GLG class library is used by an application to
load, display and update the HMI screens with real-time data. The
library provides a concise but extensive
programming API that allows developers to configure the HMI displays at
run time, as well as to handle user interaction.
The Toolkit's open
and flexible framework makes it easy to embed HMI screens into existing
SCADA applications without a need to rewrite the existing code, and
it saves months of
when developing new custom control and monitoring solutions.
A choice of
several API packages is available, from basic to intermediate and advanced.
for OEM Use
The GLG HMI Configurator,
a simplified version of the HMI
editor for the end-users, is also available. It may be used for
OEM distribution by system integrators and can be extensively
customized with custom actions, icons, dialogs, data browser and other custom
Configurator may also
be used for developing cloud-based
SCADA and monitoring systems,
where a customer creates a drawing, specifies real-time data sources
uploads the drawing to a server for a web or mobile deployment.
