1. A modular exception-based distributively intelligent I/O system comprising:

  • at least one central processing unit coupled to a communications network;

    at least one zone interface module coupled to said communications network and to an open bus via a first open bus interface;

    at least one zone processor coupled to said open bus via a second open bus interface; and

    at least one intelligent I/O module coupled to said open bus via a third open bus interface, said at least one intelligent I/O module including a processor core coupled to said third open bus interface and a universal I/O interface coupled to said processor core, said universal I/O interface enabling interaction between said processor core and at least one field element;

    whereby, programming objects may be downloaded from said central processing unit to said at least one zone interface module, said at least one zone processor and said at least one intelligent I/O module to achieve distributive control within said modular exception-based distributively intelligent I/O system.
