ABSTRACT:
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.
