Abstract
A node for online firmware upgrade in a process control system includes components. Each component is a separate executable running in a separate operating system process as provided by a real time operating system of the node. A new component is created for each of the components to be upgraded such that each new component is implementing a part of the firmware upgrade corresponding to its component to be upgraded. Each new component is a separate executable running in a separate operating system process. Runtime data is synchronized in each new component with runtime data of its corresponding component to be upgraded. Each component to be upgraded is replaced with its new component.
