The described techniques enable a skid communicator tool to quickly change network settings to those required by a particular skid or network in a process control environment with which a user of the tool wishes to establish communication. These techniques are helpful because skids and networks in process control environments often require different network settings for any device attempting to communicate with the skids or network, and a user often must manually load these network settings every time she wants to communicate with a different network or skid. By contrast, the techniques enable the skid communicator tool to seamlessly connect to, disconnect from, and reconnect to any of the skids or other networks requiring different network settings with minimal input from the user, thus enabling a user to easily move through and interact with different areas, units, or equipment of the process control environment.

Quick connection techniques for skid communicator tool

A method for efficiently managing configuration of modular control systems includes Detecting a communicative coupling between a workstation and a modular control system, determining whether an active project stored in a memory of the workstation matches a saved project stored in a memory of the modular control system, where each of the active project and the saved project includes a respective coordinated set of data for controlling operation of the modular control system, and when the active project and the saved project do not match, (i) determining whether the active project is correct for the modular control system, and (ii) when the active project is incorrect the modular control system, automatically providing, via an interactive user interface, a control for transferring at least a portion of the saved project from the memory of the modular control system to the active project in the memory of the workstation.

Assistant application for a modular control system

Techniques for assessing and managing versions of a configuration file associated with a modular control system of a process plant are described. According to certain aspects, systems and methods device may access data associated with multiple versions of a configuration file, including a computing device version and a control version, as well as a last backup instance of the configuration file. The systems and methods may compare the versions and determine any discrepancies between the versions, including which of the versions is the most recent. The systems and methods may present information associated with the comparison to enable a user to select which of the versions may be need to be updated, resolved, or provided to the controller so that the modular control system may be properly configured.

Systems and methods for assessing configuration files associated with a process control system

An enhanced modular controller is disclosed that includes a plurality of configurable communication ports and a control logic layer operable to control equipment of a process plant. The plurality of communication ports include a first set of communication ports and a second set of communication ports which are operable to communicate with one or more nodes of a distributed control system of the process plant. The enhanced modular controller also includes a software layer that accepts port configuration parameters that define one or more port communication rules for the first set of communication ports and for the second set of communication ports. The one or more port communication rules causes the software layer to selectively allow or restrict retransmission of incoming messages, where the incoming messages are received at the first set of communication ports or the second set of communication ports.

Systems and methods for enhanced modular controller port to port communication

A modular control system includes a modular controller that implements control logic of the modular control system, where the controller is built natively on a platform of a distributed control system, equipment configured to perform a physical function in a process plant according to the control logic, and a configuration database storing configuration parameters of the modular control system. In a first mode of operation, the modular control system operates as a standalone module, and in a second mode of operation, the modular control system operates natively as one or several nodes of a distributed control system.

Systems and methods for merging modular control systems into a process plant

Techniques for flexibly configuring an operating process plant or process control system enable a change to a parent object to be selectively propagated to child objects derived from the parent object, so that a first subset of child objects and their respective instantiations are updated with the change, while a second subset and their respective instantiations remain unchanged. The parent object may be a class or instance process object corresponding to a process entity, and the first and/or the second subset of child objects may be selected. In some cases, the change may have been a propagated change, to the parent object, from a child object that is excluded from the first or the second subset of child objects. In some cases, the change may first be propagated to an instance object derived from the parent object, and then propagated from the instance object to a child object.

Distribution policy for propagation of changes to process control objects

Methods and apparatus to automatically link process control graphics to process control algorithm information are described. An example method involves displaying a first process control image including process control algorithm information and displaying adjacent to the first process control image a second process control image to include process control graphics. The method automatically links at least some of the process control algorithm information to a graphic in the second process control image in response to user inputs associated with the first and second process control images.

Methods and apparatus to create process control graphics based on process control information

A configuration system uses process plant items that may represent, or be capable of representing, entities in a process plant to assist in configuring, organizing, and changing the control and display activities within the process plant. Access to the items may be controlled by associating access control data with the items. The configuration system may also use objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant. Access to these objects may be controlled by associating access control data with the objects. The access control data may indicate whether users or certain users may be able to, for example, view or modify all or some data associated with the process plant items or the objects. The process plant items may comprise, for example, module class objects which may be capable of generically representing process entities of the process plant, module objects which may be capable of specifically representing process entities of the process plant, composite templates, module templates, etc. The objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant may comprise, for example, phase classes or unit phases.

Security for objects in a process plant configuration system

A process control system includes module-level attributes that may be used to control access for writing information to unit module objects and module objects. A security check process examines the module-level attributes, which may include OPERMODE and OPERLOCK attributes, the values of which determine whether information may be written to unit module objects or module objects. The values of the module-level attributes may be controlled based on whether a particular module object is being used by the process control system.

Operator lock-out in batch process control systems

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 astute 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.

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.

Version control for objects in a process plant configuration system

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.

Secure data write apparatus and methods for use in safety instrumented process control systems

An apparatus having a programmable processor and a memory for performing a plurality of user-selectable control functions includes a database for storing a plurality of items associated with each of the control functions. The items include, for each function, at least one procedure for performing an action associated with the control function and a specification of at least one state associated with the control function. The apparatus further includes software routines stored on the memory and adapted to be executed by the processor that facilitate selection of a procedure in the database, that access the database and cause performance of the selected procedure to achieve the state specified therein, and that monitor at least one resource associated with the action of the procedure and, based thereon, determine whether the specified state has been achieved.
