Abstract

A system and method for real time updating of process applications includes a first execution engine executing a first process application to control a process device, an update manager receiving an updated software, the update manager being a second software container deployed in the deployment unit; initializing the updated software in a second execution engine; determining an application state of the first process application; instructing a transfer of the application state from the first execution engine to the second execution engine; instructing the second execution engine to execute the updated process application using the received application state; and instructing the first execution engine to stop writing output signals for the process device, and instructing the second execution engine to write output signals for the process device.
