Protocol Mapping Configuration UI Design

Overview

This document outlines the comprehensive UI design for configuring database-to-protocol mappings through the dashboard interface, supporting Modbus, OPC UA, and other industrial protocols.

🎯 Design Goals

Intuitive: Easy for both technical and non-technical users
Visual: Clear representation of database-to-protocol data flow
Configurable: Flexible mapping configuration without code changes
Validated: Real-time conflict detection and validation
Scalable: Support for multiple stations, pumps, and protocols
Protocol-Agnostic: Unified interface for Modbus, OPC UA, and other protocols

🏗️ Architecture

Data Flow

Database Sources → Mapping Configuration → Protocol Endpoints
    ↓                    ↓                    ↓
pump_plans.speed_hz → Setpoint mapping → Modbus: Holding register 40001
pumps.status_code   → Status mapping   → OPC UA: ns=2;s=Station.Pump.Status
safety.flags        → Safety mapping   → Modbus: Coil register 0
flow_meters.rate    → Flow mapping     → OPC UA: ns=2;s=Station.Flow.Rate

        self.protocol_mappings: List[ProtocolMapping] = []
    
    def add_protocol_mapping(self, mapping: ProtocolMapping) -> bool:

# Modbus Server Integration
class ModbusServer:

        self.configuration_manager = configuration_manager
        
    async def _update_registers(self):

🔍 Validation Rules

Protocol-Specific Validation

Modbus Validation:

Register addresses: 0-65535
Address ranges must not overlap
Data type compatibility with register type
Valid byte/word order combinations

OPC UA Validation:

Valid Node ID format
Namespace exists and accessible
Data type compatibility
Access level permissions

Cross-Protocol Validation

Database source must exist and be accessible
Transformation rules must be valid
No duplicate mappings for same data point

📊 Performance Considerations

Protocol-Specific Optimizations

Modbus: Batch register writes for efficiency
OPC UA: Use subscription model for frequent updates
All: Cache transformed values and mapping configurations

🔒 Security Considerations

Protocol Security

Modbus: Validate register access permissions
OPC UA: Certificate-based authentication
All: Role-based access to mapping configuration

🚀 Implementation Phases

Phase 1: Core Protocol Mapping

Basic mapping configuration for all protocols
Protocol-specific address configuration
Real-time preview and validation
Integration with existing protocol servers

Phase 2: Enhanced Features

Drag & drop interface
Protocol templates
Bulk operations
Advanced transformations

Phase 3: Advanced Features

Protocol discovery and auto-configuration
Mobile responsiveness
Performance optimizations
Advanced security features

📝 Testing Strategy

Protocol-Specific Testing

Modbus: Register read/write operations, address validation
OPC UA: Node browsing, data type conversion, security
Cross-Protocol: Data consistency, transformation accuracy
