    摘要: A method to upgrate software for the control of a process plant wherein a control component of a process control system (105) is upgraded while the process control system (105) maintains active control process operations, the method comprising running an existing component (815) of the software in a portion of a process control system memory as part of active control process operations; instantiating a replacement component (825) of the software in a portion of a process control system memory while the process control system (105) is actively controlling the process using the existing component (815); copying state data from an existing control component to the replacement control component using communication circuitry of the process control system (105) while the process control system (105) is maintaining active operations using the existing component (815); and changing the replacement component (825) to an active mode when a first state of the replacement component (825) matches a second state of the existing component (815); characterised by routing a first portion of inputs from the existing component (815) to the replacement component (825) while routing a second portion of inputs, distinct from the first portion of outputs, through the existing component (815) while maintaining control process operations using both the existing component (815) and the replacement component (825).

    摘要: Methods and apparatus to upgrade and provide control redundancy in process plants are disclosed. Redundancy is distributed within the process control system by using free resources of other active control devices and/or within the active control device itself.
    Input(s) (305) from one or more field devices (130-132,145 and/or 146), and/or from a control algorithm and/or control component (310-312). These control components (310-312) may be implemented and/or carried out by one or more controllers. The allocation of the control components (310-312) to controllers and the choice of amount of redundant copies of a particular control component may be static and/or dynamic. If the assignment is dynamic, the allocation may be adjusted, for example, based on the number of available controllers and/or the current and/or historical processing loads of the available controllers.
