This involved upgrading an obsolete touch panel HMI, improving the process and performing fault-finding on the software and electrical system, and commissioning the installation of the 5th cooking vessel.

Project Features

  • Upgrade HMI hardware from obsolete Proface screen to Allen-Bradley PanelView Plus.
  • Redesign screen to improve operator interface and incorporate 5th cooking vessel.
  • Modifications and additions performed on existing PLC program to improve performance.
  • Software design and commissioning to add new 5th cooking vessel with improved sensor feedback and control.
  • Provide design options for improving the system hardware.


Following the above improvements resulted in improved production capability and reliability.
