# Phase 3 Completion Summary: Setpoint Manager & Protocol Servers
|
|
|
|
## ✅ **PHASE 3 COMPLETED**
|
|
|
|
### **Overview**
|
|
Phase 3 successfully implements the core control logic and multi-protocol interface layer of the Calejo Control Adapter. This phase completes the end-to-end control loop from optimization plans to SCADA system integration.
|
|
|
|
### **Components Implemented**
|
|
|
|
#### 1. **SetpointManager** (`src/core/setpoint_manager.py`)
|
|
- **Purpose**: Core component that calculates setpoints from optimization plans
|
|
- **Safety Integration**: Integrates with all safety framework components
|
|
- **Key Features**:
|
|
- Safety priority hierarchy (Emergency stop > Failsafe > Normal)
|
|
- Three calculator types for different control strategies
|
|
- Real-time setpoint calculation with safety enforcement
|
|
- Graceful degradation and fallback mechanisms
|
|
|
|
#### 2. **Setpoint Calculators**
|
|
- **DirectSpeedCalculator**: Direct speed control using suggested_speed_hz
|
|
- **LevelControlledCalculator**: Level-based control with PID-like feedback
|
|
- **PowerControlledCalculator**: Power-based control with proportional feedback
|
|
|
|
#### 3. **Multi-Protocol Servers**
|
|
- **REST API Server** (`src/protocols/rest_api.py`):
|
|
- FastAPI-based REST interface
|
|
- Emergency stop endpoints
|
|
- Setpoint access and status monitoring
|
|
- Authentication and authorization
|
|
|
|
- **OPC UA Server** (`src/protocols/opcua_server.py`):
|
|
- Asyncua-based OPC UA interface
|
|
- Real-time setpoint updates
|
|
- Structured object model for stations and pumps
|
|
- Background update loop (5-second intervals)
|
|
|
|
- **Modbus TCP Server** (`src/protocols/modbus_server.py`):
|
|
- Pymodbus-based Modbus TCP interface
|
|
- Register mapping for setpoints and status
|
|
- Binary coils for emergency stop status
|
|
- Background update loop (5-second intervals)
|
|
|
|
#### 4. **Main Application Integration** (`src/main_phase3.py`)
|
|
- Complete application with all Phase 3 components
|
|
- Graceful startup and shutdown
|
|
- Signal handling for clean termination
|
|
- Periodic status logging
|
|
|
|
### **Technical Architecture**
|
|
|
|
#### **Control Flow**
|
|
```
|
|
Calejo Optimize → Database → SetpointManager → Protocol Servers → SCADA Systems

Safety Framework Calculators Multi-Protocol
|
|
```
|
|
|
|
#### **Safety Priority Hierarchy**
|
|
1. **Emergency Stop** (Highest Priority)
|
|
- Immediate override of all control
|
|
- Revert to default safe setpoints
|
|
|
|
2. **Failsafe Mode**
|
|
- Triggered by database watchdog
|
|
- Conservative operation mode
|
|
- Revert to default setpoints
|
|
|
|
3. **Normal Operation**
|
|
- Setpoint calculation from optimization plans
|
|
- Safety limit enforcement
|
|
- Real-time feedback integration
|
|
|
|
