| Abstract: The various technologies presented herein relate to upgrading industrial
control software in real-time. During utilization of a first software to
control an industrial process, a determination can be made that the first
software needs to be replaced (e.g., partially or entirely) owing to a
newer version of software is ready to be deployed, a vulnerability in the
first software has been determined, etc. Rather than closing the
industrial process down while the first software is replaced, a second
software can be deployed such that the first software and the second
software are operating in parallel (e.g., receiving the same operational
data, process states). When a critical point (upgrade location) in the
first software has been reached, control of the industrial process can be
switched to the second software, thereby enabling control of the
industrial process to occur without having to temporarily cease operation
and/or monitoring of the industrial process. |
