HMI and SCADA systems
HMI, SCADA and BAS development for alarms, trends, equipment control, diagnostics and operational visibility.
Delivery approach
Effective operator interfaces reduce ambiguity. AranVision develops and improves screens around the decisions operators need to make, the faults maintenance teams need to isolate and the information engineering teams need to review.
Scope clarity
An operator interface should communicate plant state without requiring the user to interpret software internals. The design starts with tasks: starting equipment, responding to deviations, isolating a failed permissive and confirming recovery. Navigation, colour, symbols and faceplates are then applied consistently so the same condition has the same meaning throughout the application.
Tag quality and control ownership are verified at the interface boundary. A polished screen cannot compensate for stale data, ambiguous PLC logic or an alarm that does not identify the affected equipment and required response. Testing therefore includes commands, feedback, security, communication loss, alarm history, trends and restart behaviour.
Every engagement begins with a written boundary for access, production impact, client-supplied information, approvals and third-party responsibilities. Recommendations are tied to the evidence available at the time. If field discovery changes a critical assumption, the effect on scope, testing and acceptance is reviewed before the work proceeds.
Project readiness
These checkpoints keep responsibilities visible and prevent important interfaces from becoming late-stage surprises.
Project outcomes
Programming, controls documentation, integration, testing and commissioning support are delivered within the agreed responsibility matrix. Any regulated professional engineering, electrical contracting, panel certification or authority approval is identified separately and assigned to the appropriately licensed or authorized party.
Typical deliverables
The final scope is adjusted to the installed system, project stage, client standards and site responsibilities.
HMI and SCADA screen development
Alarm rationalization support
Tag, communication and device mapping
Trend and diagnostic views
User-access and change-control considerations
FAT, SAT and handover records
Delivery method
Identify the process states, deviations and actions that each screen must communicate.
Use repeatable symbols, colours, navigation and alarm behaviour across the application.
Verify commands, feedback, bad-quality states, alarms, trends and communication-loss behaviour.
Common questions
Yes. Screen hierarchy, diagnostics, alarms and trends can often be improved while preserving the installed control platform.
Yes. Support can include HVAC and utility controls, alarm investigation, field-device diagnostics, modernization planning and commissioning.
