Abstract: An optical communication system including an optical communication fiber and a plurality of modules. Each of the modules has an optical transceiver that is optically coupled to the optical communication fiber by a corresponding optical drop. And each of the transceivers is configured for transmitting and/or receiving one or more optical signals via the optical communication fiber. The optical signals represent a plurality of individual data streams formatted according to one or more different communication protocols. In this manner, optical communication is enabled among the modules via the optical communication fiber.

Abstract: The invention provides, in one aspect, human machine interface (HMI) methods and apparatus that permit users to search and/or view plant and other real-time process automation data in a manner similar to that with which they search and/or view pages on the Internet (web). Related aspects of the invention provide such methods and apparatus as permit users to search and/or view such real-time process automation data concurrently with such Internet web pages. Further related aspects of the invention provide such methods and apparatus as permit users to search and/or view such real-time process automation data concurrently with business data maintained in pages on an enterprise network (e.g., a LAN, WAN or otherwise).

Abstract: A field controller for use in a distributed control system including an area controller and at least one field controller. The field controller manages at least one controlled device in an industrial process operation. The field controller comprises a processor module segment through which it can control a selected number of devices, and it may also include one or more expansion module segments to enable it to control a larger number of controlled devices. The processor module segment includes a processor module and at least one local interface module for interfacing to a controlled device, and the expansion module segment includes interface modules for interfacing to other controlled devices. In the processor module segment, the processor module and said local interface module are interconnected by a bus segment, which is also connected to an upstream off-module connector.
