What is the difference between PLC, HMI and SCADA?

A PLC executes real-time control logic on the plant floor; an HMI is the operator's local visualisation and control screen; SCADA supervises and records data across the wider system. Aras engineers all three as an integrated solution.

Can Aras upgrade or integrate an existing control system?

Yes. Aras can migrate, extend or integrate existing PLC, HMI and SCADA systems, and connect them to reporting and higher-level networks.

Which platforms does Aras work with?

Aras works with major PLC/SCADA platforms and selects them to match the client's site standard and existing infrastructure.

PLC, HMI & SCADA Systems

Aras Power Systems designs and commissions PLC, HMI and SCADA systems that give operators a clear, real-time view of production, utilities and process equipment. Our solutions turn field signals into reliable control logic, intuitive operator screens, alarms, trends and reports that help teams run plants safely and efficiently.

Each system is engineered around the process requirement, selected hardware platform, site network architecture and long-term maintenance strategy. From single-machine HMI applications to distributed SCADA systems, Aras delivers scalable automation with practical diagnostics and future expansion in mind.

Our Services

Control architecture and PLC engineering

System architecture: defining PLC, remote I/O, network, panel and operator-station structure according to process criticality.
PLC software: developing structured control logic, interlocks, permissives, sequences, motor controls and equipment diagnostics.

HMI and SCADA development

Operator-focused screens: designing clear process graphics, faceplates, alarms, trends and setpoint controls for faster decision-making.
Historical data: configuring data logging, trend pages, production summaries and event records for troubleshooting and optimization.

Integration and commissioning

Field integration: connecting instruments, drives, valves, MCCs and package units through suitable I/O or communication protocols.
Testing support: providing I/O checks, loop tests, FAT, SAT and start-up support to reduce commissioning risk.

Frequently asked questions

Can Aras integrate a new SCADA system with an existing PLC?

Yes. We review the existing PLC platform, communication options, tag structure and required operator functions, then design a practical migration or integration plan.

Do you provide remote access and reporting?

Yes, when required. Remote access, reporting, historical trends and user authorization are engineered according to the client’s IT and cyber security rules.

Can the system be expanded later?

Yes. We design the I/O, network and software structure with spare capacity and clear documentation so future expansion is easier and safer.
