Project Challenges

The task was to replace all Omron PLCs and upgrade to new Control Logix PLCs; and at the same time to upgrade the existing FIX HMI screens and convert them to iFIX screens.

The challenge consisted in the fact that all changes and replacement of the whole control system needed to be done without any downtime to the plant and to keep it running in auto all of the time.
