Crocosaurus Cove – PLC Platform Migration & HMI Upgrade
Controls Engineering Upgrade
Project Snapshot
Following the successful DDC upgrade, Crocosaurus Cove engaged TEC to complete a full PLC platform migration to the Beckhoff environment.
TEC retained the original control intent while improving alarm management, system monitoring, remote access, and operator visibility - delivering a more reliable, maintainable, and user-friendly controls platform across the facility.
Location: Darwin, NT
Client: Crocosaurus Cove
Sector: Commercial/Tourism
Completed: December 2022
The Challenge
Crocosaurus Cove’s existing PLC system had limited alarm visibility, poor event monitoring capability, and no remote access functionality.
The ageing platform created operational and maintenance challenges for the facility team, while reducing visibility across critical systems. The migration needed to be completed under live operational conditions without disrupting day-to-day site activities.
What TEC Delivered
TEC completed a full PLC migration and controls upgrade, including:
Migration of the existing PLC system into the Beckhoff platform
Retention and conversion of the original control philosophy
Improvements to alarm management and event visibility
End-to-end I/O validation and full loop checking
Development of a new HMI with site-specific graphics and navigation
Creation of improved alarm lists and monitoring interfaces
Implementation of secure remote access and alarm notifications via cellular gateway
Minor switchboard repairs and termination improvements during commissioning
All works were completed under live-site conditions while maintaining operational continuity.
The Outcome
The project was delivered on time and within budget, with no safety incidents and no disruption to site operations.
The upgraded platform delivered:
Improved system reliability
Better alarm visibility and event monitoring
Secure remote access capability
More intuitive operator control and navigation
Improved long-term maintainability
During commissioning, minor switchboard issues were identified and rectified on site without impacting program delivery.
The result was a modern, remotely accessible controls platform providing the facility team with greater operational visibility and confidence across key systems.
