Abstract: A system includes at least one industrial control and automation field device and a remote terminal unit (RTU). The RTU includes input/output (I/O) terminals configured to be coupled to the field devices. The RTU also includes one or more I/O modules having one or more reconfigurable I/O channels configured to be coupled to the I/O terminals. Each reconfigurable I/O channel is configurable as an analog input, an analog input supporting digital communication, an analog output, an analog output supporting digital communication, a digital input, a digital output, and a pulse accumulator input. The RTU further includes at least one processing device configured to control a configuration of each of the one or more reconfigurable I/O channels.

Abstract: A system includes redundant first process controllers configured to communicate over redundant supervisory networks in an industrial process control and automation system. Each first process controller is configured to operate in primary or secondary mode. The system also includes redundant second process controllers configured to communicate over redundant industrial control networks in the industrial process control and automation system. Each second process controller is configured to operate in primary or secondary mode. The system further includes a private network configured to communicatively couple the first and second process controllers. Each controller could be associated with at least three Media Access Control (MAC) addresses.

Abstract: A system operating in a Windows environment that provides notification of events to OPC clients is disclosed. NT events generated in the system are filtered and converted to an OPC format for presentation to the OPC clients. The converted NT event notification includes a designation of the source that generated the NT event. The system includes a filter configuration tool that permits entry of user-defined filter criteria and transformation information. The transformation information includes the source designation, event severity, event type (simple, tracking and conditional), event category, event condition, event sub-condition and event attributes.

Abstract: A method and synchronized data repository provider that synchronize data of repositories among a plurality of computing nodes is disclosed. Each node includes a synchronized provider, which communicates with the synchronized providers in the other nodes to synchronize the data of the repositories. The communication is with data synchronization messages, which are multicast by a sending node via a multicast communication link to all of the other nodes. A synchronization scope as well as a class limits the data of a repository. A repository is initialized via a point-to-point communication link with another node. The method and synchronized provider include the capability to handle response storms, lost messages and duplicate messages.
