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 method and system for integrating alarms is provided. An external alarm is received at a process control system and includes an external tag. An internal alarm that is associated with the external alarm is determined based on a map. An internal tag associated with the external tag is also determined based on the map. The process control system generates the internal alarm which includes the internal tag and is based on the external alarm. A method and system for generating alarm and tag relations is also provided. At least one external tag associated with an external system is selected. At least one internal tag associated with a process control system related to the external tags is determined. At least one entry in a map is generated to indicate a relation between at least one of the external tags and at least one of the internal tags. At least one external alarm associated with the external system is selected and at least one internal alarm related to the external alarms is determined. At least one entry is generated in the map to indicate a relation between at least one of the external alarms and at least one of the internal alarms.

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, diagnostic and display 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 applications 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 diagnostic application within a user interface to automatically treat this data differently depending on the source (or destination) of the data.

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.

Example methods and apparatus to display localized resources in a process control system are disclosed. A disclosed example method includes receiving in a server a locale identifier and a resource identifier from an application, identifying via the server a language file in a database that corresponds to the locale identifier, determining via the server using the language file a resource included within a memory that corresponds to the resource identifier, accessing the resource from the memory via the language file, and sending via the server the resource to the application to display the resource in a format associated with the locale identifier.

Example methods and apparatus to draw attention to information presented via electronic displays to process plant operators are disclosed. A disclosed example method to draw attention to information presented to a process plant operator comprises presenting an electronic process plant display, collecting process plant data, processing the process plant data to identify a portion of a process plant, and modifying the electronic process plant display to at least partially obscure substantially all of the process plant display except for the identified portion.
