    摘要: A cause and effect function block, which can be easily integrated into a function block diagram programming environment in a process plant safety system to implement the cause and effect logic specified by a traditional cause and effect matrix, includes a set of cause inputs and a set of effect outputs. A multiplexer within the cause and effect function block receives each of the cause inputs and is coupled to one or more state machines, with a separate state machine existing for each effect output. The multiplexer decodes each of the cause inputs and, based on the cause inputs and previously identified cause and effect matrix logic, provides a trip signal to one or more of the state machines. Upon receiving a trip signal, a state machine forces an associated effect output into a tripped or safe state. If desired, the state machine may then use one or more other signals, such as signals from a user or from the process, to transition between a set of different states used to safely return the process plant back to the normal operating state from the tripped or safe state.

    摘要: Secure data write apparatus and methods for use in safety instrumented process control systems select a parameter associated with a process control element within the process control system and send first data associated with the parameter to the process control element. A confirmation associated with a request to write the first data to the process control element is received from a user and the second data is sent to the process control element in response to receiving the confirmation. The first and second data are compared at the process control element and the first or second data are written to a location in the process control element associated with the parameter if the first and second data are at least substantially identical.

    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.

    摘要: An alarm display and interface tool for use in a process control system receives and displays different categories of alarms, including for example, device alarms and hardware alarms as well as traditional process alarms, on a single display to enable an operator or other user to view and have access to these different categories of alarms. The display and interface tool may be used to filter the alarms that are displayed according to any number of categories, including the category of the alarm, the priority of the alarm, the status of the alarm, etc. so as to alternatively segregate or combine the tasks typically associated with operator, maintenance and engineer personnel. The tool may also be used to access each of the displayed alarms to obtain more information about any individual alarm.

    摘要: A control system, a safety system, etc., within a process plant may each use one or more state machine function blocks that can be easily integrated into a function block diagram programming environment. Such a state machine function block may include one or more inputs, which may cause a state machine implemented by the state machine function block to change states. The state machine function block may determine a next state to which it is to transition based, at least in part, on data indicative of the next state to which to transition, if any. The configuration data may be retrieved from a database based on the current state of the state machine and at least one of the inputs. The state machine function block may also include one or more outputs that are generated based on the state of the state machine.
