Hello neharika; First, I cannot help you with the second part of your question,maybe someone from the LOGO! confrence can help you more and tell you the genesis of the name. As for the first part, concerning the details of the smart relay architecture, I have a feeling it would be even more difficult in obtaining than for other Siemens controllers. Start by having a look at these sites: http://www.klocknermoeller.com/moeller.electric/moeller.electric.pdfs/w7581en.pdf http://ab.rockwellautomation.com/Programmable-Controllers/Pico-System http://www.ia.omron.com/product/family/1755/index_fea.html http://www.ge-ip.com/products/family/durus-plc http://www.larsentoubro.com/lntcorporate/uploads/product/smart_relay%20new%20151209.pdf http://www.baldor.com.au/prodmenu.php?PRODCAT_ID=11You can notice the basic design in all of the proposed units from different manufacturers is very similar, even though some detailsd will change: colour, number of IOs, expansion units, communication standards... You can easily guess that this is a rebranded programmable logic module, produced by one (or more) providers for all major brands, So commercially, the basic design architecture should be very well protected... As for who designs the original module, it seems that on the web thereare a lot of opinions, but little hard data¸; some say Siemens produuces the IDEC, or Moeller makes all the smart relays on the market. For example: http://www.plctalk.net/qanda/showthread.php?t=8187 http://forums.mrplc.com/index.php?showtopic=4855

The word LOGO is an acronym to LOGIC ORIENTED GRAPHIC ORIENTED. |
