Control Engineering Embedded Control eNewsletter for September 2002
Embedded control in September Control Engineering
Control Engineering's September issue is posted on the Web. Dave Harrold's cover story topic is integrating control and safety in process control applications. In an article specific for embedded and machine control, I discuss some of the new object-oriented programming tools coming out to help you write better programs, faster and easier. These include IEC 61499 and 61804 function blocks. 61499 specifically addresses distributed control programming while 61804 is more specific to process control applications. Also discussed is Siemens ProfiNet initiative. Check these out, and more, at controleng.com

What's hot at IMTS
There were several control and control-related product improvements exhibited at the recent IMTS show. As you might expect, most were CNC-related, but read on.
The new Cimplicity iCell from GE Fanuc Automation is a supervisory software package that manages multiple CNC machine tools from a central location. It supports such operations as parts machining, data collection, remote diagnostics, and state-change monitoring, as well as enabling quick recovery in the event of a failure. This is part of the company's overall retooling of offerings designed to help end-users improve machine uptime and overall productivity by implementing Six Sigma standards.

MDSI, champion of PC-based, open CNC and motion control, has enhanced its OpenCNC package with new servo algorithms increasing cutting speeds up to 25% over the previous version and expanded rotary tool center point compression. The company shared its booth with several OEMs who have standardized on OpenCNC including Fryer Machine, Raycon, and Telco Automation.

Let's get started
'Among the sweetest words you can hear at work, right after 'take the day off,' are these twin beauties: `Let's give it a try,' and, 'Let's see what happens.' How glorious it is to stop discussing, committee-ing and deliberating, and actually START. As good old Will Shakespeare put it, 'Action is eloquence.' (We can only be grateful that Shakespeare had no high school counselor to convince him to do some sensible career planning.)'
Dale Dauten, business writer and consultant, started his latest 'E-Luminations' newsletter with the thought above. I'm taking this thought a different direction than he did, applying it to manufacturing. How many have bosses caught up in the analysis game? How many of you are caught in that trap?
Once I was quality assurance manager in a manufacturing plant (a position I swore I'd never hold again!) We had some machines consistently producing bad parts. My urge was to solve the problem. I'd dig in and figure out if the problem lay in raw materials, the die, the control, whatever. My boss's advice? 'Write a memo blaming the manufacturing engineering manager and copy the general manager.' That's it. I like Mr. Dauten's advice. Or as Nike puts it, 'Just do it.'

Control remote devices
A technology slowly growing into its own is remote device management. I probably first heard about this at a Motorola semiconductor conference where a Coke machine was shown that could dial up its owner and say, 'Hi, I'm out of regular and getting low on diet.' Embedded software combined with ever-improving communications, processors, and memory.
Axeda (formerly eMation and PC Soft before that) has staked its future on what it calls 'Device Relationship Management' and has recently integrated its technology into its Wizcon SCADA software.

Matt Miller, marketing manager for OSIsoft, recently explained to Control Engineering editors that company's Echo Historian (Embedded Component Historian Object). This really is a different solution than Axeda's. Its larger footprint is meant to provide real time and archived machine or process data. Remote diagnostics and predictive maintenance are two prominent benefits.

Tony Phipps, product manager for Intrinsyc Software in an interview at the Microsoft Embedded Web site, suggests that remote device management software can make use of many technologies in providing an end-to-end solution for customers. He states that the key is to focus on open standards and offer solutions that are non-proprietary. Internet-based technologies have become a central part of remote device management solutions. One should ensure the solution is simple to use and administered with little end-user involvement, fits within current business systems, and can collect and manage key data from remote devices when developing an application.
There is still life in embedded product development
New products for the embedded control space keep appearing.
Here are some small controllers, communications products, and peripherals. Here's a $99 palm-sized PLC that includes a metal enclosure, nine inputs, nine outputs, program selectable input (analog, pulse, high speed counter), 10-bit resolution analog input, 32 timers and 32 counters, 256 internal relays, and real-time clock. IP99 series from International Parallel Machines.

ç Create and debug your control program and configure and use the built-in Human Machine Interface (HMI) all from a Java-enabled Web browser (including PDAs). No other software is required! The Icon controller from i-netcontrol also includes a historical data recording system for periodic and event(alarm) data, with e-mail capability. The product communicates through Ethernet or serially through an auto-answer modem, which uses PPP, plus serial RS-232/485 RTU Modbus for sensor and instrument data input and output control.
