The challenge

A HMI to integrate data from four PLCs controlling over 300 metres of conveyors across three floors, alongside two automated box closer/gluer lines. As the single point of control, the interface had to present large volumes of real-time data clearly, enabling quick navigation and rapid fault identification while maintaining reliability and responsiveness.

The solution

  • 3 instances of the HMI around the system. All able to control the system
  • Live CCTV integration to aid safe starting of the system
  • Live Motor health pages and real time sensor diagnostics with postioning overlay
  • Full Integration with 3rd party systems to centralise fault finding
