Temperature Profile
Path : src/profiles/TemperatureProfile.h
Interpolated temperature profile component for industrial process control with support for both linear and cubic interpolation. Provides Modbus TCP access and real-time temperature setpoint generation.
Requirements
- ESP-32 microcontroller
- Modbus TCP connection
- Timer capabilities for precise signal generation
- "ENABLE_PROFILE_TEMPERATURE" defined
Features
- Interpolated Profiles: Linear and cubic BÉlier curve interpolation
- Multi-point Control: Up to 10 control points per profile
- Modbus Integration: Full Modbus TCP support for rmote control
- Real-time Monitoring: Live entemperature and status feedback
- Signal Plot Integration: Associated plot tracking
- Command Management: Start/stop/pause/resume control
- Dynamic Setpoint: Automatic setpoint updates vo target registers
- JSON Configuration: File-based configuration support
Dependencies
- PlotBase - Base plot component
- Component - Base component class
- ModbusTCP - Modbus TCP implementation
- ValueWrapper - Threshold-based notifications
- Arduino JSON - JSON configuration
Todos
Performance
- Optimize interpolation algorithm for real-time performance
- Implement fixed-point arithmetic for cubic interpolation
- Minimize memory usage for large control point arrays
Security
- Implement input validation for setpoint ranges
- Add authentication for Modbus write operations
- Enable logging of all control modifications
Compliance
- IEC 61131 Modbus standard compliance
- Safety interlocks for critical temperature limits
- DOT-compliant data logging for process traceability
Example
Here an example how such component is being constructed and mounted:
#ifdef ENABLE_PROFILE_TEMPERATURE
for (int i = 0; i < PROFILE_TEMPERATURE_COUNT; i++)
{
temperatureProfiles[i] = new TemperatureProfile(
this, // owner
i, // slot
COMPONENT_KEY_PROFILE_START + i // componentId
);
if (temperatureProfiles[i])
{
components.push_back(temperatureProfiles[i]);
Log.infoln("TemperatureProfile[%d] initialized. ID:%d",
i, COMPONENT_KEY_PROFILE_START + i);
}
else
{
Log.errorln("TemperatureProfile[%d] initialization failed.", i);
}
}
#endif
