    • 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.
    • 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。

    • 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.
    • 过程工厂包括物理和逻辑上与过程控制系统集成的安全系统,使得安全系统和过程控制系统可以在过程工厂内使用公共通信,配置硬件和软件,同时仍然在安全系统之间提供功能隔离 控制器和过程控制系统控制器。 该集成过程控制和安全系统为安全系统和过程控制系统使用通用的数据通信结构,使得配置应用程序可以以相同的方式向系统中的设备发送数据和接收数据,例如使用相同的方式 通信硬件和软件。 然而,建立公共数据通信结构以将过程控制系统设备与安全系统设备区分开,使用发送给设备或从设备接收的消息内的标签,地址或其他字段,这使得与过程控制系统相关联的数据可区分 来自与安全系统相关联的数据,从而使得用户界面内的配置应用能够根据数据的来源(或目的地)自动对待该数据。
