A method is described for the closed-loop control of a time-delayed process having compensation, in particular for temperature control. After a setpoint value step-change, the manipulated variable is set at a first constant value in an open-loop controlled operation, an IT1 model is identified on the basis of the step-change response and a PI controller is parametrized, which closed-loop controls the process into a second steady state. Subsequently, a more exact process model having compensation...

A mediation system as disclosed herein is capable of performing a method for facilitating mediated communication. In at least one embodiment of the method for facilitating mediated communication, the method includes receiving a service selection from a mediation subscriber communication device, determining a context associated with the service selection, and preparing plurality of contextual arrangement options in response to determining the context.

Internet web pages displayed via an Internet web browser or other applications are automatically customized. Dynamic "Web Components" are used to automatically customize web pages. Further, these Web Components use the same script and HTML for all implementations or instantiations of the Web Component regardless of which, or how many, unique local clients make use of the Web Component. This code reuse is accomplished by using entry web pages, or "entry points," as described in further detail bel...

An apparatus and system are disclosed for real-time monitoring and control of field assets. A monitoring device may be coupled to a field asset to determine the occurrence of one or more error conditions. Error conditions may be detected either as they occur or by testing the field asset at timed intervals. Upon detection of one or more error conditions, the monitoring device may initiate one or more corrective sequences to resolve the error condition. Alternatively, the monitoring device may no...

Power line monitoring is disclosed. The monitoring can be performed in conjunction with an automation system designed to control and monitor devices and sensors. Model-based power line monitoring uses a model of acceptable power line activity. Activity that does not conform to the model is tagged as indicating a potential problem. Pattern-based power line monitoring uses patterns of unacceptable power line activity. Activity that matches one of the patterns is also tagged as indicating a potenti...

A network master (M) having charge of an operation of a main device (L) and one or more network slaves (S1 to S3) each having charge of a safety determining device (A to C) for determining safety which is an operating permission condition of the main device (L) are connected on the network. Each network slave comprises means for selectively performing a first operation for transmitting information including data for maintenance of the safety determining device or both determination output of the...

A processor core for realizing efficient operation processing by connecting an extended arithmetic unit to its exterior and a processor incorporating such a processing core are provided. The processor includes the processor core, a data memory accessed by the processor core, and the extended arithmetic unit connected to the exterior of the processor core for processing a particular instruction. The extended arithmetic unit executes an arithmetic operation by using arithmetic operation data retai...

An electromagnetically operated valve assembly (28) has a first solenoid (58) and a second solenoid (60). An armature (56) having a valve stem (54) coupled thereto is positioned between the first solenoid (58) and second solenoid (60). A controller (12) is coupled to the first solenoid (58), the second solenoid (60). A current sensor (49) is coupled to the first solenoid and generated a signal corresponding to the induced current in the first solenoid. The controller (12) changes a voltage appli...

A control system methodology that uses object-oriented software to integrate multiple control systems into a common object model. Object-oriented techniques are used to construct distributed applications in a multi-vendor open system environment for use in controlling and monitoring systems of varying size and configuration. Information is brought into a common object model and made available throughout the system. A custom programming language is included for object creation. Access to objects ...

A method of and apparatus for synchronous control of a leading element and a follower element in which synchronism is started smoothly and a mechanical shock at the start of synchronism is reduced. When the follower element is started to move to be synchronized with the leading element, motion of the follower element is started before the follower element reaches a start position of the synchronism, and brought into synchronism with the leading element at the start position of synchronism. A pos...
