    摘要: A process controller implements an overall, user-developed control strategy in a process control network that includes distributed controller and field devices, such as Fieldbus and non-Fieldbus devices. A user defines the control strategy by building a plurality of function blocks and control modules and downloading or installing user-specified portions of the control strategy into the Fieldbus devices and the non-Fieldbus devices. Thereafter, the Fieldbus devices automatically perform the downloaded portions of the overall strategy independently of other portions of the control strategy. For example in a process control system that includes distributed field devices, controllers and workstations, portions of the control strategy downloaded or installed into the field devices operate independently of and in parallel with the control operations of the controllers and the workstations, while other control operations manage the Fieldbus devices and implement other portions of the control strategy.

    摘要: A process controller implements and executes a standard set of function blocks or control functions defined by a standard protocol so that standard-type control is achieved with respect to non-standard-type devices. The process controller enables standard devices to implement the standard set of function blocks and control functions. The process controller implements an overall strategy as if all connected devices are standard devices by usage of a Fieldbus function block as a fundamental building block for control structures. These function blocks are defined to create control structures for all types of devices.

    摘要: A process controller implements an overall, user-developed control strategy in a process control network that includes distributed controller and field devices. A user defines a module control strategy by specifying function blocks that make up control modules and determine the control strategy. The user modifies or debugs a module control strategy by adding, modifying and deleting function blocks, configuring parameters associated with the function blocks and creating a view to new attributes. By defining function blocks and control modules, a user-defined control strategy, application program or diagnostic program is represented as a set of layers of interconnected control objects identified as modules. A layer of the control strategy includes a set of modules which are interconnected in a user-specified manner. A module typically includes an algorithm for performing a specific function and display components which are used to display information to a user. A module is optionally represented to include a set of input and output connections for connecting to other modules. A module may be considered to be a "black box" which performs a specified function and is connected to other modules via specified input and output connections.

    摘要: A process control or safety system within a process plant uses one or more testing blocks to effect the timely and safe operation of on-line testing routines within field devices, such as valves, used in the process control or safety system. These testing blocks, which are easy to implement and to place in the process control or safety system, enable the periodic or on-demand testing of field devices to be integrated into the normal and on-going operation of the process control or safety system without causing scheduling or connection problems and without the need to rely on maintenance or other personnel, thereby providing better monitoring of the operational status of the field devices used within the process control and safety systems. This functionality is especially important in safety systems, in which it is desirable to timely monitor or assess the operational status of the devices used to shut the process down when an unsafe condition arises, so as to assure that initiation of a shut down by the safety system actually results in a shut down of the system.

    摘要: A configuration system for a process plant uses module class objects to assist in configuring, organizing and changing the control and display activities within the process plant. Each module class object generically models or represents a process entity, such as a unit, a piece of equipment, a control activity, etc., and may be used to create instances of the object, called module objects, which represent and are tied to specific equipment within the process plant. The module class objects may represent process entities of any desired scope, which means that a single module class object may be used to configure the control and display activities of process entities of any desired scope within the process plant, instead of just at a control module level. In particular, module class objects of a large scope may be used to configure large sections or portions of the process plant, which makes configuration of the process plant easier and less time consuming. A module class object may be a unit module class object reflecting a physical unit within the process plant, an equipment module class object reflecting a physical piece of equipment within the process plant, a control module class object reflecting a control module or scheme within the process plant, or a display module class object reflecting a display routine that provides information to a user within the process plant.

    摘要: A version control system helps to keep track of versions of process plant items that may represent, or be capable of representing, entities in a process plant. The process plant items may comprise, for example, module objects which may be capable of specifically representing process entities of the process plant. These module objects may be created from module class objects which may be capable of generically representing process entities of the process plant. Version data is stored and associated with a module object. The version data may comprise data indicative of a version of a module class object that was used to create the module object. The version data may also comprise data indicative of a version of the module object. Configuration systems, version control systems, viewing systems, debugging systems, run-time monitoring systems, asset management systems, etc., may examine or permit viewing of the version control data associated with an item.
