SCADA & HMI Development

Engineering Service provides SCADA & HMI Development for industrial organizations that need dependable real-time visualization, supervisory control, alarm management, production reporting, and secure remote operations across mixed-vendor automation environments. The firm designs operator-centric applications for discrete, batch, and continuous processes, scaling from single-machine HMIs to multi-site SCADA systems with segmented networks, redundant servers, and disaster-recovery considerations. Typical deliverables include a Functional Design Specification (FDS), control narrative and I/O mapping support, ISA-101 screen standards, alarm philosophy, tag and naming conventions, security model, test procedures, and fully validated application code with commissioning and as-built documentation. Engineering Service develops on proven platforms including Siemens WinCC Unified/Professional and WinCC OA, Rockwell FactoryTalk View ME/SE and FactoryTalk Optix, AVEVA System Platform and AVEVA InTouch, Schneider Electric Citect SCADA, ABB Ability System 800xA, Ignition by Inductive Automation, Mitsubishi GOT2000, and CODESYS Visualization. For data historians and reporting, the firm integrates AVEVA PI System (OSIsoft PI), FactoryTalk Historian, Microsoft SQL Server-based historians, and time-series databases, with dashboards delivered via web clients, thin clients, and mobile-ready views where appropriate. Application architecture is engineered for maintainability: consistent templates, reusable faceplates, centralized alarm classes, and version-controlled configuration to support long-term lifecycle management. Operator effectiveness and process safety are addressed using standards-based methods. HMI design follows ISA-101 High Performance HMI guidance to reduce cognitive load through consistent navigation, appropriate use of color, and clear abnormal situation cues. Alarm systems are engineered in alignment with ISA-18.2 and IEC 62682, including alarm rationalization workshops, prioritization rules, shelving and suppression logic, deadbands, and nuisance-alarm reduction. Where Safety Instrumented Systems (SIS) interfaces are present, Engineering Service supports documentation and change practices aligned with IEC 61511/ISA 84, ensuring the HMI/SCADA layer presents clear status without compromising safety functions. For batch and enterprise integration, the firm applies ISA-88 and ISA-95 concepts to structure equipment models, recipes, and production data flows. Connectivity and interoperability are designed around supportable industrial protocols and clear data models. Engineering Service implements OPC UA/DA, Modbus TCP/RTU, EtherNet/IP, PROFINET, DNP3 (utility and power interfaces), and MQTT with Sparkplug B for scalable publish/subscribe telemetry. Integrations to MES, CMMS, ERP, and analytics platforms are delivered using SQL, REST APIs, and secure message brokers, with attention to timestamp fidelity, units, scaling, and event/state models. Remote access and cybersecurity are engineered using IEC 62443 zoning and conduit principles, including hardened server builds, least-privilege role-based access control, secure VPN or jump-host architectures, and audit-ready logging. The firm’s execution methodology covers requirements capture, architecture design, simulation and I/O testing, FAT/SAT planning, cutover strategy, and operator/maintenance training. Whether modernizing legacy “classic” screens, migrating from older SCADA versions, or deploying a new redundant architecture with high availability, Engineering Service delivers maintainable SCADA and HMI applications built for uptime, auditability, and long-term supportability.
