Ian,Here is a good one for the FUN network. Let's see if we can show the"POWER" of FF technologyRich-----Original Message-----From: lgoldberg@putman.net [mailto:lgoldberg@putman.net] A reader needs help. If you can offer advice about the question posedbelow, please reply to CDTheAnswer@putman.net as soon as possible. Thisquestion was published in the October issue and your answers will appearin April. Thanks for contributing.April's ProblemWe have been asked to build a machine that will perform integratedhigh-speed discrete parts assembly as well as simple batch and PID loopcontrol. We're considering using a hybrid control (process automationsystem?) to ensure integrated machine functions as opposed to DCS (toocostly) or a straight PLC solution. First of all, how do we distinguishbetween a hybrid controller and the more conventional DCS and PLCsolutions? Second, does anyone have any experience in evaluating andimplementing these solutions for integrated process (liquid) anddiscrete manufacturing? What criteria should we consider when evaluatingthe options?Send us your comments, suggestions, or solutions for these problems.We'll include them in the April 2002 issue. Send visuals, too?a sketchis fine. Have a problem you'd like to pose to the readers? Send it alongto us at: The Answer to Your Problems, CONTROL DESIGN, 555 W. PierceRd., Suite 301, Itasca, IL 60143.
