| 20120104295 | ACTUATOR CONTROL DEVICE AND METHOD - A device for controlling an actuator includes an input interface that receives a plurality of input signals including a setpoint command signal and a feedback signal. An output interface provides a drive signal to the actuator. First, second, and third redundant loop controllers processes the setpoint command signal and the feedback signal to generate respective actuator control signals. A primary controller compares the actuator control signals to determine whether at least two are substantially similar. The device outputs the drive signal to the actuator according to an actuator control signals that has been determined by the primary controller to be substantially similar to another. Any one of the redundant loop controllers is hot swappable with a replacement loop controller such that loop controller redundancy is operatively maintained by the device in controlling the actuator while one of the redundant loop controllers is hot swapped. | 05-03-2012 |

| 20100087935 | COMPLETE INTEGRATION OF STAND-ALONE BATCH OPERATOR INTERFACE CAPABILITIES INTO GENERIC HUMAN MACHINE INTERFACE USING COMPONENTIZED OBJECTS - 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. | 04-08-2010 |
