The original NIST effort was to develop exactly the kind of integrated factory environment implied by Stuart's "management application above EMC2 to hand the synchronization of discrete EMC2 processes" but across entire enterprises.
Under Jim Albus's leadership, folks* at NIST developed the multi-platform Realtime Control Sytem (RCS) for factory automation. Computers, workcells, etc., speaking the Neutral Messaging Language (NML) were connected via the Communication Management System (CMS). EMC/EMC2 implements a portion of this technology in its bowels. (You can look all this stuff up via Google, Wikipedia, or the NIST archives.) I agree with Stuart's analysis that the processes discussed seem not to need real time response, but I don't think the original poster has ever spelling out just what his multi-station system has to accomplish. Regards, Kent *full disclosure: I never worked on factory automation but my group at NIST received some support from the program because we were engaged in the development of IGES and STEP for an allied industrial sector. ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
