Industrial Automation and SCADA Engineer with 9+ years of hands-on experience specializing in the Siemens automation ecosystem, SCADA/HMI development, custom runtime scripting, and OT-IT system integration. Proven expertise in architecting, standardizing, and deploying high-reliability visualization views, custom faceplates, and communication pipelines across discrete manufacturing, process lines, and mission-critical utilities.
Core Technical Competencies:
- SCADA & HMI Systems: Siemens WinCC Classic (V7.5 to V8.1), WinCC Professional, WinCC Advanced (TIA Portal V14–V18), Simatic Manager v5.6, and Comfort HMI panels (KTP600, KTP1200, TP900).
- Programming & Scripting: C#, .NET (Visual Studio), VBScript (VBS), Structured Text (SCL), STL, Ladder Logic (LAD), JavaScript, and SQL.
- PLC Hardware & Engineering: Siemens S7-1500, S7-1518, S7-1200, S7-400/400H, S7-300, and S7-200 Smart series.
- Industrial Communication & OT-IT Integration: Modbus RTU/TCP, OPC DA, OPC UA, Profinet, MQTT, S7 Protocol (via S7.NET driver), and industrial networking with Siemens Scalance switches and LTE routers.
- Database & Archiving: Microsoft SQL Server (MSSQL), SCADA process value logging, dynamic alarm archiving, audit-trail compliance, and automated report generation.
Project Experience & Delivery:
- SCADA View & Graphic Template Standardization: Created structured SCADA screens, standardized UI faceplates, and contextual pop-up windows adhering strictly to design guidelines, template libraries, and ergonomic navigation standards.
- Dynamic Runtime Logic: Authored complex VBScript and C# modules within WinCC runtime environments to execute animated state visual indicators, setpoint validation, alarm routing, and multi-tier user access control.
- Tag Mapping & Engineering Verification: Executed signal mapping between Siemens S7 PLCs and SCADA tags, cross-verifying electrical schematics, P&IDs, and instrumentation lists.
- Process Automation & Testing: Conducted full offline simulation, view testing, and signal commissioning, identifying and documenting punch-list items and technical specifications to ensure zero-defect handovers.
- Development Process Optimization: Automated repetitive view-generation, screen layouts, and tag-binding routines using custom C#/.NET tools to drastically shorten engineering delivery cycles.
