摘要： Methods and apparatus to upgrade and provide control redundancy in process plants are disclosed. An example disclosed method to upgrade software for a control device of a process control system comprises instantiating a replacement component of the software, copying state data from an existing component to the replacement component, and changing the replacement component to an active mode when a first state of the replacement component matches a second state of the existing component.

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 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。
