SCADA & HMI Services

Patrion’s SCADA & HMI Services deliver end-to-end engineering for industrial automation projects across process, power, water, and discrete manufacturing sectors. The firm engineers and modernizes supervisory control architectures on leading platforms — Siemens WinCC / TIA Portal, Rockwell Automation FactoryTalk View and System Platform, AVEVA InTouch, Schneider EcoStruxure, ABB 800xA, Emerson DeltaV, Honeywell Experion, and Yokogawa CENTUM/Exa — and integrates IIoT solutions with Inductive Automation Ignition and AVEVA/OSIsoft PI. Services include HMI graphic design following ISA-101 high-performance HMI principles, alarm management and rationalization per ISA-18.2, and functional safety alignment to IEC 61511 and IEC 61131-3 PLC programming practices. Patrion configures secure, interoperable communications using OPC UA/DA, EtherNet/IP, PROFINET, Modbus TCP, DNP3, MQTT, and BACnet, and implements historian architectures with AVEVA PI, Wonderware Historian, Rockwell Historian or SQL Server-based historians. The firm designs high-availability SCADA topologies (active/active and active/passive server redundancy), virtualization on VMware ESXi or Microsoft Hyper-V, disaster recovery, and network segmentation consistent with IEC 62443 and NIST cybersecurity guidance. Edge computing strategies are deployed using platform-native edge nodes or containerized microservices for local HMI, deterministic I/O, and data aggregation. Patrion’s workflow covers requirements capture, HMI prototyping, alarm philosophy development, KPI dashboards, advanced trending, ad-hoc and scheduled reporting, and historian data modeling. Engineering deliverables include detailed I/O mapping, tag structures optimized for OPC UA and MES integration (ISA-95), RESTful API endpoints for ERP connectivity, and data normalization for ML/analytics. Testing and validation services include Factory Acceptance Testing (FAT), Hardware-in-the-Loop (HIL) simulation, Site Acceptance Testing (SAT), loop checks, and operator training with runbooks and procedures. For brownfield upgrades, Patrion performs vendor-agnostic migration planning to move legacy SCADA (Modicon, RSView32, Wonderware) to modern platforms with phased cutovers, replica databases, and dual-run strategies to minimize production risk. The firm also implements alarm shelving, dynamic alarming, suppression logic, and KPI-based dashboards to reduce nuisance alarms and improve situational awareness. Remote access solutions combine secure VPN, jump hosts, and PAM/Citrix where required, and Patrion engineers OT/IT convergence projects with integrated cybersecurity controls, role-based access, and audit logging compliant with ISO 27001 and IEC 62443. Globally deployable and field-proven, Patrion’s SCADA & HMI Services provide plant managers and control engineers with measurable improvements in operator performance, downtime reduction, and actionable process visibility.
