HVAC Control in the New MillenniumAnother unit called a DeviceNet Message Display uses an LCDdisplay to provide alphanumeric messaging, operator instructions andI/O status. These DeviceNet-addressable, 4- by 20-character, back-litunits can store up to 16 messages in nonvolatile memory. The display iscontrolled using standard DeviceNet commands. Multiport Taps providefor the extension of a DeviceNet network by allowing more nodesto be connected to the trunk line, as compared to a single-port tap or thedirect connection of a node to the trunk line.ReferencesBursky, Dave, “Electronic Glasses of the Future Deliver Data, Provide Feedback,”Electronic Design, June 23, 1997, Vol. 45 No. 13, p. 32.Chouinard, Don, “Windows CE: the Value’s in the Details,” Instrumentation andControl Systems, Vol. 72 No. 6, June 1999, pp. 41-47.Daflucas, Mark, “The Road to Mass Customization,” Industrial Computing, Vol.17 No. 6, June 1998, pp. 18-19.Derfler, Jr., Frank J., “Networks Will Be Ubiquitous,” PC Magazine, Vol. 18 No 12,June 22, 1999, p. 114.Gottesman, Ben Z., “Software Will Get Smarter,” PC Magazine, Vol. 18 No. 12,June 22, 1999, pp. 128-131.“Industrial Computers,” Industrial Computing, Vol. 18 No. 12, November 1999,pp. 12-13.“Industrial Software,” Industrial Computing, Vol. 18 No. 12, November 1999, pp.21-23.Kinnear, Dave, “Low-power Processors Create Performance Trade-offs for WindowsCE,” Wireless Systems Design, Vol. 3 No 6, June 1998, pp. 18-22.Klein, Mike, “Realizing PC-based Control True Potential,” Industrial Computing,Vol. 18 No. 9, August 1999, pp. 15-16.Labs, Wayne, “Software: Open Source OSs, Objects, Web-based CommunicationsChallenge Status Quo,” Instrumentation and Control Systems, Vol. 72 No. 7,July 1999, pp. 25-49.Levin, Carol, “Little Devices Will Think,” PC Magazine, Vol. 18 No. 12, June 22,1999, pp. 120-123.Levin, Carol, “Safety in Random Numbers,” PC Magazine, Vol. 18 No. 12, June22, 1999, p. 30.Miller, Michael J., “Computers Will Be More Human,” PC Magazine, Vol. 18 No.12, June 22, 1999, pp. 104-113.Rupley, Sebastian, “The Web Will Be Smart,” PC Magazine, Vol. 18 No 12, June22, 1999, pp. 116-119.Rupley, Sebastian, “You’ll Look at Computers in a Whole New Way,” PC Magazine,Vol. 18 No. 12, June 22, 1999, p. 134.Stamm, Nick, “Moore’s Law Will Continue to Drive Computing,” PC Magazine,Vol. 18 No. 12, June 22, 1999, pp. 146-147.©2001 by The Fairmont Press, Inc.
