Terry, While I am still quite wealthy, recent events in the market have taken my net worth from incalculable to merely astronomical. And although not quite as tech savvy as my advisor on all things tech Mr. Milum, I liked letterbugs. I thought that having letterbugs and slot / rack independence was better than PLC style I/O addressing. I also have loaded the HPS configurator (what does HPS stand for anyway) into a windows mobile Samsung phone where it fails completely. So there you go. COTS is fine as long as you don't need to use it for more than a few years. Open any techies desk drawer and look at all of the debris: Imation superdisks, 8", 5.25" 3.5" floppies, unsupported flash memory cards (various flavors), thick wire ethernet, thin wire ethernet, fiber connectors. And almost all of it came and went since the I/A system came about 21 years ago. In the future I/A will stand for Iphone / Applications and the whole plant will run on those. I was gonna get an Iphone, but those things are expensive. Regards, David >But only Dave Johnson can afford that kind of security. The rest of us >would rather spend a buck or so for a letterbug. > >Terry Doucet _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
