Data acquisition software is hardly a "new kid on the block." The commercial use of software-configured control systems dates back to the 1970s, when the first large-scale proprietary control systems debuted. As the control industry has evolved, so have software-based systems.

With the evolution of the personal computer and the networks on which they "reside," software developers are producing products adaptable to just about any type of control situation. In fact, original research by Control Engineering (Des Plaines, Ill.) found that respondents use data acquisition and control (DAC) software across a gamut applications. The ability of software to be adapted to a broad base of applications, speaks volumes for the ability of software developers to produce systems that are adaptable, scalable, and easy to use.

In the traditional blues tune, "House of the Risin' Sun," the lyrics state, "I got one foot on the platform, I got one foot on the train, I'm going back to New Orleans to wear that ball and chain. In choosing a platform for PC-based software, users seem to have both feet planted firmly in the personal computer. Nearly 41% of those responding use PC-based systems. Other types of control system platforms were not neglected, however. DAC software found itself at home, though not equally, on PLC, DCS, and hybrid systems. However, even with the pervasiveness of the PC, control engineers are far from considering it a ball and chain.

How about an operating system!

Choice of an operating system fell to Microsoft products. Most respondents used either Windows 3.1, 95, or NT. DOS and Unix systems were the only other operating systems mentioned in the survey results. However, the number of DOS-based operating systems in use exceeded Microsoft 3.1, indicating in a surprising number of cases, that older technology is "staying alive."

Networked and standalone DAC systems are used by relatively the same percentage of respondents (44% vs. 42%). Almost three-fourths of users answering the question have an Ethernet network. Proprietary systems, Internet-, and intranet-based networks made up the remainder.

What's on the shopping list?

Control engineers have an extensive list of features they want in DAC software. The most requested was Transmission Control Protocol/ Internet Protocol (TCP/IP) compatibility. This combination transport layer protocol and network layer protocol is commonly used for communications within networks and across the Internet.

The rest of the list reads like alphabet soup. DDE (dynamic data exchange), OLE (object linking and embedding), ODBC (open database connectivity), and OPC (OLE for Process Control) all help make configuration seamless and less complicated. ActiveX, a Microsoft product, and Java, a cross-platform programming language developed by Sun Microsystems, are unique but share object-technology capability. Both systems offer potential users greater ease of setup in today's complex control applications.

Control engineers' "wish list" also indicates ease of use is very much an issue. In fact, survey results rank this characteristic number one. It was followed very closely by a software supplier's ability to provide technical support. Other desirable items include the user's ability to customize, such as directly tailoring screens, network and data base configuration, terminology, report generation, product availability; and, finally, product cost.

As PCs continue to expand into new areas of industrial control, the need for appropriate DAC software will also expand. Additionally, evolution of the elusive "open" control system will do much to standardize and simplify software offerings in the future. It is a safe bet that DAC software developers will be able to keep their offerings on the PC control "Hit Parade."

Wide ranging data acquisition

Irvine, Calif.— Integrated application modules in FactorySuite 2000 development toolkit make use of a high performance, open communication layer called SuiteLink.
