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 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 or may not cause a state machine implemented by the state machine function block to change states. The state machine function block may also include a plurality of outputs. Output configuration data associated with the function block may indicate values of the outputs of the function block for each of the states of the state machine. The state machine function block may use this output configuration data to determine its outputs when in a particular state.

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.

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.
摘要翻译：一个因果函数块，可以轻松地集成到一个过程工厂安全系统的功能框图编程环境中，以实现由传统因果矩阵指定的因果逻辑，包括一组原因输入和一组的效果输出。原因和效果功能块内的多路复用器接收每个原因输入，并且耦合到一个或多个状态机，其中存在用于每个效果输出的单独的状态机。多路复用器解码每个原因输入，并且基于原因输入和先前识别的因果矩阵逻辑，向一个或多个状态机提供跳闸信号。在接收到跳闸信号时，状态机强制相关联的效果输出进入跳闸或安全状态。如果需要，状态机可以然后使用一个或多个其他信号，例如来自用户或来自过程的信号，以在用于将处理设备安全地从处理器返回到正常操作状态的一组不同状态之间转换或安全状态。

摘要： A software object approval system is integrated with a process control or safety system environment and, in particular, with a process control or safety system design environment to implement and manage electronic approval of new software objects created within the process control and safety system environment. The software object approval system electronically generates identification information representing a group of entities whose approval is needed prior to implementing a software object within the process control or safety system. The system may then send the software object to the entities and receive from each entity an electronic indication regarding approval of the software object. The approval system prevents the process control or safety system from implementing the software object until each entity within the group of entities approves the software object.
