摘要： A system and method configures a communication link in a process control system having a controller connected to an I/O device via a remote I/O communication link, which has a local and a remote I/O interface communicatively coupled via a remote I/O communication bus. The system and method specifies a remote connection between the controller and the I/O device, recognizes that the remote connection requires communications over the remote I/O communication link, and automatically generates communication objects to route communications between the controller and the I/O device via the remote I/O communication link.

摘要： A system and method for interfacing a plurality of field devices which are communicatively coupled on a communication network via a standard communication protocol with a process control system uses a linking device to seamlessly integrate communications between the field devices and a controller within the process control system. The system and method uses the linking device to emulate the communication characteristics of the field devices to link information in field devices with information in a controller of the control system, thereby allowing control loops to include combinations of function blocks from both the field devices and the controller. The linking device uses a link active schedule to monitor substantially all communications on the communication network connecting the field devices and selectively processes and analyzes the monitored communications. The information processed by the linking device, which may include function block information, is automatically routed from a field device to the controller or from the controller to a field device. Other information, such as field device identification information and/or communications diagnostic information, may be collected by the linking device and sent to a user.

摘要： 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.

摘要： A system and method for managing delivery of a link active schedule has a master link active scheduler and a backup link active scheduler communicatively coupled together via a databus. The system and method stores a link active schedule in a master link active scheduler and automatically transmits the most current link active schedule from the master link active scheduler over the databus to the backup link active scheduler upon receipt of the link active schedule in the master link active scheduler.
