    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 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 voter function block, which can be integrated into a function block diagram programming environment in a process plant control or safety system, implements voter logic in conjunction with providing operational and maintenance overrides which may be set to override individual inputs to the voter function block as well as to override the output of the voter function block. The voter function block, which is easy to create, use, test, debug and document, includes one or input limit detection units which detect if a particular redundant input has reached a specified limit indicating a condition within the process plant, an override unit that may be set by a user to override the consideration of that input in the voting function, a voting logic entity that determines if a trip condition exists based on the values of the valid or non-inhibited inputs, and an inhibit block that may used to override the output of the voter logic block during, for example, a startup or other operational condition. The voter function block may be integrated into a process control or safety system by being communicatively connected to other function blocks, such as to analog or digital input function blocks, analog or digital output function blocks, control function blocks, cause and effect function blocks which implement cause and effect logic, etc. Within the process control or safety programming environment.

    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 plant includes a safety system that is physically and logically integrated with a process control system such that the safety system and the process control system can use common communication, configuration hardware and software within the process plant while still providing functional isolation between the safety system controllers and the process control system controllers. This integrated process control and safety system uses a common data communication structure for both the safety system and the process control system so that the configuration application can send data to and receive data from devices in either system in the same manner, e.g., using the same communication hardware and software. However, the common data communication structure is set up to distinguish process control system devices from safety system devices using tags, addresses or other fields within the messages sent to or received from the devices, which enables data associated with the process control system to be distinguishable from data associated with the safety system, thereby enabling a configuration application within a user interface to automatically treat this data differently depending on the source (or destination) of the data.
