## Temperature Profile

**Path** : [src/profiles/TemperatureProfile.h](../../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](./plot-base.md) - Base plot component
- [Component](../component.md) - Base component class
- [ModbusTCP](../modbus/modbus-tcp.md) - Modbus TCP implementation
- [ValueWrapper](../value-wrapper.md) - Threshold-based notifications
- [Arduino JSON](https://arduinojson.org/) - 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:

```cpp
#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
```
