The present invention is for automatic reconfiguration of industrial networked devices. More particularly, the system described herein facilitates use of TCP/IP networks, such as Ethernet, as an alternative for industrial fieldbus or device buses by removing the need to perform significant reconfiguration of devices such as I/O modules, sensors, or transducers under field replacement situations. The present invention uses a monitor agent to track the IP and MAC addresses of networked devices as well as port information. If a device fails, maintenance personnel make an in-field replacement of the failed device and the monitor agent automatically reassigns the IP address to the replacement device.

A sequence of events (SOE) recorder facility in a process control network environment is described herein. The SOE recorder facility is hosted by a networked node that receives digital signal status change (event) data from a networked controller. The sequence of events recorder facility receives a configured set of digital data signals from the controller, temporarily buffers the events in chronological order according to timestamps assigned to the events by their sources (e.g., fieldbus modules). The data is thereafter copied/removed from the buffer and provided to multiple destinations including: a process database that maintains an archival copy of the received event data for rendering event reports, and an SOE client user interface for rendering event logs to printers and/or graphical user interface displays.

A method or apparatus automatically configures a control module for synchronous execution on a Fieldbus segment of a process control network by determining if all of the critical function blocks of a particular control module can be assigned to FOUNDATION® Fieldbus field devices or to the I/O device associated with a particular Fieldbus segment. If so, the method or apparatus automatically assigns the function blocks of the control module, which would otherwise be scheduled to execute in a controller, to the I/O device for the Fieldbus segment. This technique enables all of the critical or necessary function blocks within the control module to execute in one macrocycle of the Fieldbus segment, thereby executing synchronously on a Fieldbus segment. This operation, in turn, increases the overall execution rate of the control module with respect to control modules that have function blocks split between a controller and field devices on a Fieldbus segment, which has been the traditional manner of configuring control modules implemented using devices on a Fieldbus segment.

Enhanced HART device alerts enable HART devices within a process control system to report alarm or alert conditions that are detected within the devices to a system user or operator using a plurality of intuitive device status conditions, each of which corresponds to a different level of severity and each of which may require a different type of response by the system user or operator. The status conditions are consistent with enhanced Fieldbus device alerts and include a condition associated with a failure of a HART device, a condition associated with maintenance needed by a HART device and an advisable action in connection with a HART device.

An interface module is operatively connected to a Fieldbus process control network and to at least one non-Fieldbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to corresponding process control parameters of the non-Fieldbus process control network. Once the Fieldbus process control parameters are mapped to the non-Fieldbus process control parameters, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the database. The interface module may also function in the other direction to map non-Fieldbus process control parameters to corresponding Fieldbus process control parameters.

The present invention is directed to facilitating communication within an automation system having a plurality of networks and network protocols. Specifically, a Modbus network is operably connected to a network. A fieldbus coupler operably connected to both networks having a program facilitates communication within the automation system wherein devices connected to the network can be accessed for monitoring and/or controlling via Modbus commands.
