摘要： A method for generating stepper motor ramps and analyzing the motor torque required compared with the motor torque available wherein the generated ramp accelerates the motor as fast as possible while maintaining a user settable torque safety factor and/or safety margin. The method uses the minimum available stepper motor torque at the current motor speed to ultimately compute the maximum useable acceleration, uses the maximum acceleration to generate the next motor step time and hence the next motor velocity, computes the next velocity from the desired acceleration and the previous velocity and utilizes friction during deceleration of the motor. In particular, the method comprises determining the minimum available torque using the current motor velocity and the torque-speed characteristic of the motor, applying to the available torque a safety factor and then a safety margin to determine maximum useable torque wherein the safety factor is derived from motor information and the safety margin is derived from system information, calculating the maximum acceleration using the friction and moment of inertia of the system and the maximum usable motor torque, calculating the time duration of the next step for advancing the motor, repeating the foregoing steps to determine all steps in the ramps, and utilizing the generated motor ramps in advancing the stepper motor. The generated ramp always exploits the full drive capability of the stepper motor, and it provides a relatively constant margin between available torque and required torque during both acceleration and deceleration of the motor.

摘要： A data collection and viewing application associated with a batch process control system used within a process plant provides a user interface that allows a user to quickly and easily examine a particular batch process or a batch run, to compare separate batch runs and/or to determine whether the particular batch run deviates from a norm, without having to perform a lot of manual data manipulation. To this end, the user interface provides or creates a compact graphical representation of a batch, illustrating a number of different types of batch-related data in relation to one another in a manner that enables a user to easily view or understand the operation of the batch run, either alone or as compared with one or more other batch runs. Generally speaking, the compact batch view includes a number of graphical layers which are juxtaposed or interleaved on a display, with each of the layers providing different types of information about the operation of the batch, time synchronized with one another. A base layer of the compact batch view may describe or indicate the duration of the batch from an activate time to a deactivate time, while different aspects of the procedural elements, steps or stages of the batch process, such as those identified by the S88 standard, may be illustrated in one or more additional layers. Moreover, process alarms, alerts, events, etc. as well as other information may be placed in one or more additional layers, and the various layers may be shown together to provide a compact graphical view of the batch.

摘要： A process control system includes a controller that executes a control routine which performs a series of unit procedures within a process. The control routine is written or created to specify the class of unit to be used for each unit procedure, but not the actual unit itself. At the start of each unit procedure of the control routine, a dynamic unit selection routine selects a particular unit as the unit to be used during operation of that unit procedure. When called, the dynamic unit selection routine determines a set of possible units to be used, determines if each of the set of possible units is suitable for use during that unit procedure of the control routine based on a suitability criterion, prioritizes the units that meet the suitability criterion based on a priority criterion and selects the particular unit from the prioritized list of suitable units in order of priority. The dynamic unit selection routine may determine if one or more of the units on the prioritized list of suitable units is capable of being acquired and may select the first unit on the prioritized list of suitable units that is capable of being acquired as the unit to be used by the control routine.

摘要： Systems and methods for providing an integrated HMI application for monitoring and interacting with both batch and non-batch processes in a process plant are disclosed. A plurality of independent stand-alone software objects defining various batch process interface views are embedded within a non-batch process control interface application. A blackboard service is provided for storing batch control data used by the various stand alone software objects. The blackboard service may be adapted to communicate with a batch control server to receive batch control data for populating the various batch interface views with data relating to various batch processes being carried out in the process plant and to send instructions for controlling the various batches input by users via the various batch interface views. When executed by a processor, the stand alone software objects defining the various batch interface views read data from and write data to the blackboard service to communicate data between batch process interface views and preserve contextual information between interface views to allow efficient and intuitive navigation between batch process interface views.

摘要： Methods and apparatus for batch process control in which a Phase Logic Module operable in accordance with the state machine model of the batch server program is embedded within a programmable controller. More specifically, a phase executed by the batch server program in a data processing device is operable in accordance with a pre-defined state machine model (typically compliant with the ISA S88.01 standard). A Phase Logic Module (PLM) is implemented within a programmable controller in accordance with the same state machine model so as to mirror the state machine operation of the batch server process within the programmable controller. The PLM is pre-implemented and standardized. Specific state logic for performing desired control in accordance with the desired batch processing is defined by a control engineer using well known languages and tools and integrated with the standard PLM state machine. These methods and structure obviate the need for the control engineer to implement customized state processing logic and the associated need to test such complex state processing logic. The PLM in the programmable controller and the phase within the batch server program communicate using a high level communication protocol to exchange state processing information. Another aspect of the invention provides for implementing a PLM in a data processing device to perform soft phase processing (a phase unrelated to process I/O equipment and rather typically related to operator interaction).
