- 3. Execute Write Command over MQTT / Confirm Delivery (QoS)
07. Alerts Threshold Mapping (2 Days) Parse dynamic threshold target values directly from the incoming PLC data payload.
- 1. Extract threshold limit values from PLC JSON payload (e.g., Target_Temp_Max)
- 2. Evaluate real-time variable values against their mapped threshold limits
- 3. Trigger warning/alert queue if value exceeds bounds

Phase 3: Monitoring & Visualization (8 Days)

08. Main Dashboard (2 Days) High-level KPIs showing operational status and health of all connected PLCs.
- 1. Total Team Users count
- 2. Total PLCs configured
- 3. Healthy vs Unhealthy PLC connection status
- 4. Recent Alerts / Warnings feed
09. Powerplant Diagrams (GUI) (4 Days) Graphical interface showing live values and component status overlaid on plant diagrams.
- 1. Render background diagram with overlaid PLC device icons
- 2. Display real-time KPI values next to related devices
- 3. Trigger UI Alert Animations (Flashing / Color changing) when a PLC value exceeds thresholds
10. Dual-Mode Data Retrieval (2 Days) Supports both scheduled fetches (4x daily) and manual "On-Demand" live triggers.
- 1. Scheduled Data Reception: Receive and log data payloads pushed by the PLC at configured intervals
- 2. On-Demand Polling: Send trigger command to PLC; PLC responds with the latest data payload

Phase 4: Intelligence & Accountability (10 Days)

11. Multi-Channel Alerts (4 Days) Real-time notifications via Mobile Push, Email, and Admin Panel in-app pop-ups.
- 1. Admin Panel Notifications (UI feed and pop-ups)
- 2. Email Notifications (Integration with SMTP/sendgrid)
- 3. Mobile App Push Notifications (Integration with Firebase/APNs)
12. Historical Logs Viewer (2 Days) Comprehensive record-keeping with advanced filtering by date, station, or variable.
- 1. View PLC Data Logs (Received Values)
- 2. View Alert Logs (Triggered Warnings and Errors)
13. System Audit Trail (2 Days) Tracking of all user logins, configuration changes, and manual system actions.
- 1. Track Admin / Team Logins
- 2. Track CRUD operations on Users, Roles, and Permissions
- 3. Track CRUD operations on PLCs, MQTT Credentials, and Topics
- 4. Track Upload/Association of Visual Assets & Dynamic Icons
- 5. Track modifications to Alert Threshold Maps
- 6. Track "On-Demand" Live Data Triggers & "Write" Commands sent to PLC
14. Reporting & Export (2 Days) Generate downloadable XLSX/CSV reports with custom date and variable filters.
- 1. Export Historical PLC Data for specific date ranges and stations
- 2. Filter exports by specific Variable tags (e.g., only Inverter Current)
- 3. Export System Audit Trail logs (e.g., Download a CSV showing "Admin Krunal changed Device #3 Threshold to 50 at 10:00 AM")

Phase 5: Performance & Mobile (7 Days)

15. Logs Archiving (3 Days) Background logic to archive old data and maintain system database performance.
- 1. Implement Data Archiving Policy (1-Year Hot Storage retention)
- 2. Automated Cron Job to move records older than 1 year to a separate Cold Storage collection (No Deletion)
- 3. Database indexing and partitioning optimizations for high read/write throughput
16. Cross-Platform Mobile App (4 Days) Fully responsive Android and iOS apps using Capacitor to wrap the existing React Frontend.
