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.
