A look back at Microsoft in manufacturing

As we look back at how machine automation has changed since 1997, columnist Jeremy Pollard reflects on the way Microsoft-based technology revolutionized the face of machine control during that period.

10th AnniversaryBy Jeremy Pollard, CET, Columnist

Historically speaking, the record might show modern-day machine control, interfacing, and data collection didn’t start until Microsoft operating systems and applications came to the factory floor. And when exactly was that? The jury still is out on precisely when, but it’s been rolling along over these past 10 years.

The timeline on the relentless roll out of Windows operating systems can be found at TheElderGeek.com.

You can’t go to a manufacturing facility of any size and not find a PC on the factory floor that isn’t running a Microsoft OS. From Windows NT to Windows CE to Windows XP Embedded, the “preferred” solution for on-floor processing is Microsoft.

It goes beyond HMI and PLC programming software. Arguably, Microsoft touches every aspect of manufacturing software that most plants and machines use.

Where were we without Microsoft? Why have we had this love affair with its software for so many years, especially during the 1997-to-present era we’re examining for Control Design’s 10th year celebration?

I once wrote an article on Windows-based ICOM programming software for Allen-Bradley PLCs. Scott Zifferer, the visionary president of Icom ripped into me about it. “How can you tell me I’m doing something wrong when I’m the only guy out there doing Windows-based programming for PLCs?” he raged.

I’d written, “ICOM was first off the block with Windows-based programming. Is it a new way to program? That depends on whom you ask. Is it a better way to program? Same answer. Is it fast enough to be productive? Probably not, unless you have a 486/66 with 16 MB of RAM. But it’s the current future of programming environments.”

That article was published 12 years ago, not during our 10-year look-back period, but you get the idea. Look that those horsepower requirements!

Windows 2.1 actually was around in 1987, and you needed a 286 processor with 2 megabytes of RAM on an extended memory card to run it. Very bulky. 1990 was the year that Windows 3.0 was introduced, and soon after 3.1, and 3.11, which gave the masses a networking platform without having to use Novell Netware. A home-based network? That was unheard of.

Windows 98 was released in 1998-1999, hardware to run it was getting faster and cheaper, and the early adopter curve was well passed. We were off to the races.

Ten years later, the love-in continues.

Dennis Morin started Wonderware with a few of his friends back in the 1980s. Intouch was the first HMI product to run under Windows, and the first industrial application that ran on top of windows.

This is was this app that brought Windows to the factory floor, and started the whole damn thing. People wanted an alternative operator interface other than a Xycom computer and firmware-based graphics. The development of the final systems was painstaking and time-consuming. The newbies have no idea what we went through.

Wonderware made it easy, and they took over the market.

Steve Rubin, founder of Intellution agrees. “We were slow off the mark,” he says. “We didn’t think Windows would move that fast, if at all.”

The move—or non-move—to Windows made companies and broke others. Ask anyone who shot the wad on OS/2 development. IBM and Microsoft said they would work in partnership, but soon it was clear that Gates had other ides, and the bi-partisanship disappeared. USData was an HMI/SCADA supplier that was squashed when users decided that OS/2 and UNIX were no longer for them. That was their market at the time. IBM tossed in the towel on OS/2 in 2000.

Windows did not provide any top-floor connectivity until Windows NT—the first true Windows OS—arrived around 1998. It allowed for server-based applications and networking that challenged UNIX based systems.

Enter PC-based control. Windows NT became the standard for real-time control. Many companies developed networking solutions based on NT, and migrated them with clients based on Windows 95/98. Solutions allowed for systems to run as servers, and clients were on the floor. Wow.

The pervasiveness of Microsoft is as simple as realizing “they were first.” Apple had a GUI before Microsoft, but didn’t work with people who might provide guidance for product development in the industrial community. They really didn’t know—or maybe care—anything about machine builders.

The Evangelists
Microsoft presented papers at our conferences, and helped the industry understand the new strategy. Don Richardson was the application developers customer unit manager for industry. At the OMAC users group meeting in 1999 he made it clear that Microsoft was more than just HMI applications.

He suggested that from embedded devices to back-office systems (NT), Microsoft was there. Windows DNA technology, coupled with COM/DCOM began a path towards high productivity and ease-of-use gains that allowed us to accelerate our solutions, and become more productive.

The tie-in of ERP/MRP/MES systems really was where Microsoft wanted to go. This can be seen with the accelerated use of SAP and BAAN systems. Regardless of the back end, the front end is Windows. Even most Oracle database applications have Windows front ends.

DOS-based development was very different. Greg Wood, principal with Sandstone Software, suggests the move to a protected environment (windows) made everyone nervous in the development community. The methodology of using the development products (compilers) changed weekly.

But once the learning curve was climbed, he suggests that the speed at which code and products could be developed increased 10-fold. I think we’ve seen plenty of that over these 10 years.
