AUSTIN, TEXAS — March 5, 2001 — Version 4.1 of Web Studio, Indusoft's HMI and SCADA
system, now supports all available wireless networks for industrial applications, including Short
Message Service (SMS) for sending alarms to phones and pagers; Wireless Application Protocol
(WAP), the de facto standard for presentation and delivery to mobile phones and other wireless
terminals; and IEEE 802.11B. When other wireless methods are standardized for industrial use,
such as Imode and GPRS (general packet radio service), InduSoft will support those services as
Web Studio is a powerful, integrated collection of automation tools that includes all the building
blocks needed to develop human machine interfaces (HMIs), supervisory control and data
acquistion (SCADA) systems, and embedded instrumentation and control applications. Web
Studio runs in native Windows CE 3.0, NT, and 2000 environments and conforms to industry
standards such as Microsoft DNA, OPC, DDE, ODBC, XML, SOAP and ActiveX.
To help OEMs or end users develop a system, Web Studio provides a real-time graphical
interface that makes it easy to drop in the necessary modules for automating and controlling
devices such as motor drives, valve actuators, pumps and motion control systems, or to set up a
batch or continuous process control system with PID and advanced algorithms, or to integrate
discrete and continuous controls in the same package.
Because Web Studio conforms to all the necessary Microsoft standards, it can easily interface to
specialty software packages such as SoftPLC for software-based PLC controls, Think & Do and
Steeplechase for flowchart-based control, ISaGRAF, and similar systems. In such cases, Web
Studio provides the HMI, data acquisition and communications functions for the specialty
A Web Studio control system can migrate upward from an embedded, diskless CE 3.0
instrumentation controller to a large-scale NT-based supervisory or distributed control system.
This allows an OEM to use the same software across a family of products ranging from discrete
devices with embedded software to large scale, networked systems such as compressor trains,
transfer machines or a family of process control instrumentation and controls. For end users, it
means they can standardize on a single software package that can meet their needs for
everything in the plant from a simple oven control to a complex distillation tower or batch reactor.
Web Studio supports communications drivers for the majority of PLCs and smart devices from
manufacturers such as Allen-Bradley, Siemens and Fanuc, and it supports standard protocols
such as DeviceNet, ControlNet, Profibus and Ethernet. It also supports Ethernet and exports
graphics, recipe data and real-time data in the XML format, so it can communicate with handheld
PDAs and laptop PCs via wireless, desktop or industrial computers via networks, and mainframe
computers over the Internet.
The basic software package has been used for at least ten years in North America, Europe and
South America. It is licensed by OEMs all over the world, including Bosch, Fluke and Xycom.
Founded in 1997, InduSoft provides a powerful family of industrial software products for
developing applications in process supervision, automation and control for Windows 2000, NT
and CE operating systems. Today, InduSoft is developing tools and technologies to empower
people and companies to develop graphical interfaces, integrate Web browsers, and take advantage of Internet connectivity. More than 4,000 InduSoft HMI, SCADA, control and data acquisition systems are operating worldwide.
