    摘要: A configuration system for use in a process control network having a controller, a first device network that communicates using a first input/output protocol, such as a Fieldbus or a HART device protocol, and an AS-Interface device network that communicates using an AS-Interface input/output communication protocol includes a configuration database that stores configuration information pertaining to the first device network and configuration information pertaining to the AS-Interface device network, a data access routine that automatically requests configuration information pertaining to the first device network and configuration information pertaining to the AS-Interface device network and a configurator that configures the AS-Interface device network based on the AS-Interface device network configuration information. The configurator stores the AS-Interface device network configuration information in the configuration database along with configuration information pertaining to the first device network. A documentation routine accesses the configuration database to display a process control documentation schematic illustrating the configuration of the first device network and the AS-Interface device network within the process control system.

    摘要: A smart field-mounted control unit, for controlling a process, receives signals and sends a command output over a two-wire circuit which powers the control unit. An input section receives the signals, which can be instructions representative of commands or instruction sets, process variables sensed by external control units or setpoints representative of a desired process state. The instructions are representative of a control requirement of the process and adjust a controlling section in the control unit to generate the command output in conformance with the control requirement. The command output can be a function of the difference between the process setpoint and a process variable, or a function of a linear combination of a process variable and its calculated time integral and time derivative functions. A sensing section in the control unit can sense and scale a process variable for generating the command output as well. The control unit can include a regulator section, controlled by the command output, which regulates application of a mechanical, hydraulic, pneumatic or electromagnetic force applied to the process.

    摘要: A distributed adaptable measurement network, which has flexible sensor or actuator nodes, takes multiple single valued measurements, such as temperature, pH, density, turbidity, velocity, breakdown strength, and strain as a function of time. The network can control large scale physical processes in response to these measurements. The flexible sensor or actuator node uses interchangeable common core modules, where each common core module uses a common description for data configuration and control of the measurement and response parameters. Although many physical variables can be affected, each variable is controlled in the same fashion. A transducer module selects the physical variable to which the common core module will be sensitive and whether its role will be that of a sensor or an actuator. The network may also contain system transducers which can control or alter the initial measurement and response parameters selected by the transducer module.
