## EXAMPLE
The Component class is typically extended rather than used directly. Here's an example of how a derived component might be constructed and mounted:
This section illustrates how to create and configure a Component instance. Since the complete implementation in Component.cpp is not accessible, this example provides a general pattern for component creation based on the header file.
```cpp
#ifdef PIN_LED_FEEDBACK_0
ledFeedback_0 = new LEDFeedback(
this, // owner
PIN_LED_FEEDBACK_0, // pin
LED_PIXEL_COUNT_0, // pixelCount
ID_LED_FEEDBACK_0, // id
LED_FEEDBACK_0_MB_ADDR // modbusAddress
);
if (ledFeedback_0)
{
components.push_back(ledFeedback_0);
Log.infoln(F("LEDFeedback_0 initialized. Pin:%d, Count:%d, ID:%d, MB:%d"),
PIN_LED_FEEDBACK_0, LED_PIXEL_COUNT_0,
ID_LED_FEEDBACK_0, LED_FEEDBACK_0_MB_ADDR);
}
else
{
Log.errorln(F("LEDFeedback_0 initialization failed."));
}
#endif
// Create a basic component with default settings
Component* basicComponent = new Component("BasicComponent", 100, Component::COMPONENT_DEFAULT);
// Add the component to the components vector
if (basicComponent) {
components.push_back(basicComponent);
Log.infoln(F("Basic component initialized. ID:%d"), 100);
} else {
Log.errorln(F("Basic component initialization failed."));
}
// Example with an owner component
Component* parentComponent = new Component("ParentComponent", 200, Component::COMPONENT_DEFAULT);
Component* childComponent = new Component(
"ChildComponent", // name
201, // id
Component::COMPONENT_DEFAULT, // flags
parentComponent // owner
);
if (childComponent) {
components.push_back(childComponent);
Log.infoln(F("Child component initialized. Name:%s, ID:%d"),
"ChildComponent", 201);
} else {
Log.errorln(F("Child component initialization failed."));
}
```

# Plunger
**Path**: [src/components/Plunger.cpp](../src/components/Plunger.cpp)
**Revision History**: Initial documentation
The Plunger component provides control for a plunger mechanism driven by a SAKO Variable Frequency Drive (VFD). It manages plunging, homing, filling operations, and detects jams through current monitoring. The component supports both manual joystick control and automated operational modes.
## Requirements
### Hardware
- SAKO Variable Frequency Drive (VFD)
- Joystick for manual control
- Two potentiometers (POTs):
- Speed POT for controlling plunging speed
- Torque POT for controlling jam sensitivity
- ESP32 with appropriate GPIO pins for interfaces
### Configuration
- Plunger component uses the component ID 760 (`PLUNGER_COMPONENT_ID`)
- Modbus base address is configured using `COMPONENT_KEY_PLUNGER` (670)
- VFD must be properly configured to report current values
## Features
- **Manual Control**: Direct joystick-based plunger movement control
- **Automatic Operations**: Timed automatic plunging and homing
- **Record and Replay**: Ability to record plunging operations and replay them (up to 20 seconds)
- **Filling Cycle**: Automated fill procedure with configurable parameters
- **Post-Flow Control**: Additional material flow control after main operations
- **Jam Detection**: Current-based jam detection with automatic recovery
- **Modbus Interface**: Remote control and monitoring via Modbus TCP
- **Configurable Settings**: Adjustable speed, current thresholds, and timing parameters
- **Persistence**: Settings can be saved to and loaded from JSON files
## Dependencies

RESETTING_JAM --> IDLE: Reset complete
RECORD --> IDLE: Complete/Stop
REPLAY --> IDLE: Complete/Stop
FILLING --> IDLE: Complete/Stop
STOPPING --> IDLE: VFD stopped
```
## TODOs
### Performance
- Consider optimizing the current monitoring frequency to reduce CPU load
- Evaluate the need for additional filtering of current readings to avoid false jam detections
- Profile the performance impact of JSON operations for settings management
- Optimize state transition logic to reduce processing overhead
### Security
- Implement validation of Modbus command values to prevent unexpected operations
- Consider adding authentication for settings modification via REST API
- Ensure proper bounds checking for all user-configurable parameters
- Add protection against invalid state transitions triggered by external commands
### Compliance
- Verify compliance with relevant industrial safety standards for automated machinery
- Ensure emergency stop functionality meets IEC 60204-1 requirements
- Consider implementing logging for operational data to support audit requirements
- Add failure mode analysis and redundant safety mechanisms
### Recommendations
- Implement a calibration procedure for current thresholds based on actual plunger load
- Consider adding temperature monitoring to detect VFD overheating
- Add additional sensor inputs (e.g., limit switches) for improved position feedback
- Implement more sophisticated jam detection based on current trend analysis rather than fixed thresholds
- Consider expanding the configuration options to support different materials and plunger sizes
- Add persistent logging of jam events to identify patterns
## Example
This example shows how to initialize the Plunger component in a system:
```cpp
#ifdef ENABLE_PLUNGER
// Check if required components are available
if (sakoVfd && joystick && speedPot && torquePot) {
plunger = new Plunger(
this, // owner
sakoVfd, // VFD controller
joystick, // joystick for manual control
speedPot, // POT for speed control
torquePot // POT for torque/jam sensitivity
);
if (plunger) {
components.push_back(plunger);
Log.infoln(F("Plunger initialized with VFD, Joystick, and POTs"));
// Load stored settings or use defaults
plunger->loadDefaultSettings();
} else {
Log.errorln(F("Plunger initialization failed."));
}
} else {
Log.warningln(F("Plunger not initialized - missing required components."));
}
#endif
```

## EXAMPLE
This example shows how to initialize and mount a SAKO_VFD component in a system:
```cpp
#ifdef ENABLE_SAKO_VFD
sakoVFD = new SAKO_VFD(
MB_SAKO_VFD_SLAVE_ID, // Modbus slave ID of the VFD
MB_SAKO_VFD_READ_INTERVAL // Polling interval in milliseconds
);
if (sakoVFD)
{
components.push_back(sakoVFD);
Log.infoln(F("SAKO VFD initialized. SlaveID:%d, ReadInterval:%d ms"),
MB_SAKO_VFD_SLAVE_ID, MB_SAKO_VFD_READ_INTERVAL);
}
else
{
Log.errorln(F("SAKO VFD initialization failed."));
}
#endif
```

# StatusLight
**Path**: [`src/components/StatusLight.h`](../src/components/StatusLight.h)
**Revision History**: Initial documentation
The StatusLight component provides functionality to control and monitor status indicators such as LEDs. It supports three states: OFF, ON, and BLINKING, with configurable blinking intervals. It integrates with the Modbus system for remote monitoring and control.
## Requirements
- Digital output pin for connecting the status light/LED
- STATUS_BLINK_INTERVAL defined in configuration (default: 800ms)
- Optional Modbus address for network control
## Features
- Three operation modes: OFF, ON, and BLINKING
- Configurable blinking intervals
- Modbus integration for remote monitoring and control
- Serial bridge interface for local control
- Automatic pin state management during state transitions
## Dependencies
- [Component](../src/Component.h) - Base class for all components
- [Bridge](../src/Bridge.h) - For serial command interface
- [ModbusTCP](../src/modbus/ModbusTCP.h) - For Modbus network integration
```mermaid
graph TD
StatusLight --> Component
StatusLight --> Bridge
StatusLight --> ModbusTCP
```
## Behaviour
The StatusLight component manages a digital output pin with three possible states: OFF, ON, and BLINKING. When in BLINKING state, it toggles the output at the configured interval.
```mermaid
stateDiagram-v2
[*] --> OFF
OFF --> ON: set(1)
ON --> OFF: set(0)
OFF --> BLINK: status_blink(true)
ON --> BLINK: status_blink(true)
BLINK --> OFF: status_blink(false) + state==OFF
BLINK --> ON: status_blink(false) + state==ON
```
## TODOs
### Performance
- Consider using non-blocking timers for more precise blinking intervals
- Evaluate performance impact of continuous polling in the loop method
### Security
- Validate input parameters in public methods to prevent unexpected behavior
- Consider adding authentication for Modbus write operations
### Compliance
- Ensure proper error handling for hardware failures
- Add support for different blinking patterns for various status indications
### Recommendations
- Use consistent addressing scheme when multiple status lights are used
- Consider using PWM for dimming capability in future versions
- When using with critical systems, consider adding a watchdog timer
## Example
The following example shows how to initialize and use a StatusLight component:
```cpp
#ifdef STATUS_WARNING_PIN
StatusLight* warningLight = new StatusLight(
this, // owner
STATUS_WARNING_PIN, // pin
COMPONENT_KEY_FEEDBACK_0, // id
MB_MONITORING_STATUS_FEEDBACK_0 // modbusAddress
);
if (warningLight)
{
components.push_back(warningLight);
Log.infoln(F("Warning Status Light initialized. Pin:%d"), STATUS_WARNING_PIN);
}
else
{
Log.errorln(F("Warning Status Light initialization failed."));
}
#endif
// Later in the code, control the status light:
warningLight->on(); // Turn on the light
warningLight->off(); // Turn off the light
warningLight->setBlink(true); // Make it blink
```

# StepperController
**Path**: [`src/components/StepperController.h`](../src/components/StepperController.h)
**Revision History**: Initial documentation
The StepperController component provides an interface for controlling stepper motors using the AccelStepper library. It supports configuration of motor parameters such as speed, direction, and pulse width, and integrates with the Modbus system for remote control capabilities. The component monitors motor status including overload conditions.
## Requirements
### Hardware
- Direction pin (GPIO)
- Pulse pin (GPIO)
- Feedback pin (analog input, optional)
- Overload pin (analog input, optional)
### Software
- AccelStepper library
- Arduino framework
## Features
- Configurable motor direction and rotation speed
- Adjustable pulse width for motor stepping
- Modbus integration for remote control
- Motor status monitoring (running, idle, overload, error)
- Overload detection using analog feedback
- Speed clamping to prevent damage
## Dependencies
- [Component](../src/Component.h) - Base component class
- [ModbusValue](../src/ModbusValue.h) - Modbus interface
- [AccelStepper](https://www.airspayce.com/mikem/arduino/AccelStepper/) - Stepper motor control library
```mermaid
graph TD
StepperController --> Component
StepperController --> ModbusValue
StepperController --> AccelStepper
```
## Behaviour
The StepperController continuously updates the motor based on either local settings or values received via Modbus. It monitors for overload conditions and updates the motor status accordingly.
```mermaid
stateDiagram-v2
[*] --> IDLE
IDLE --> RUNNING: Speed > 0
RUNNING --> IDLE: Speed = 0
RUNNING --> OVERLOAD: Analog reading > threshold
OVERLOAD --> RUNNING: Analog reading < threshold
RUNNING --> ERROR: Hardware failure
ERROR --> IDLE: Reset
```
## TODOs
### Performance
- Consider implementing acceleration and deceleration profiles for smoother motor operation
- Evaluate interrupt-based stepping for more precise timing
- Optimize speed scaling for different motor types
### Security
- Implement limits on maximum speed and acceleration to prevent mechanical damage
- Add authentication for modbus commands that control the motor
- Consider adding emergency stop functionality
### Compliance
- Verify compatibility with industrial motor control standards
- Ensure proper error handling meets safety requirements
- Document power requirements and limitations
### Recommendations
- Use external motor drivers with proper current limiting for larger motors
- Implement soft limits and homing procedures for positioning applications
- Add physical endstops for critical applications
- Consider adding encoder feedback for closed-loop operation
## Example
Below is an example of how to instantiate and configure a StepperController:
```cpp
#ifdef ENABLE_STEPPER_0
// Create stepper controller instance
stepperController_0 = new StepperController(
this, // owner
PIN_STEPPER_0_DIR, // dirPin
PIN_STEPPER_0_PULSE, // pulsePin
PIN_STEPPER_0_FEEDBACK, // feedbackPin
PIN_STEPPER_0_OVERLOAD, // overloadPin
STEPPER_0_ENABLED, // enabled
STEPPER_0_SPEED, // speed
STEPPER_0_PULSE_WIDTH, // pulseWidth
STEPPER_0_DIR, // dir
COMPONENT_KEY_STEPPER_0, // id
MB_RW_STEPPER_0_START // addressStart
);
if (stepperController_0)
{
components.push_back(stepperController_0);
Log.infoln(F("StepperController_0 initialized. Dir:%d, Pulse:%d, Speed:%d"),
PIN_STEPPER_0_DIR, PIN_STEPPER_0_PULSE, STEPPER_0_SPEED);
}
else
{
Log.errorln(F("StepperController_0 initialization failed."));
}
#endif
```

## Configuration System
**Path**: [src/config.h](../src/config.h)
**Revision History**: Initial documentation
The configuration system is a centralized header file containing all global settings, pin definitions, platform-specific configurations, and feature flags. It provides a unified interface for configuring hardware dependencies, communication protocols, and enabling/disabling various features of the firmware.
## REQUIREMENTS
- ESP-32 microcontroller (with support for other platforms like Portenta H7, Controllino Mega)
- Platform.io development environment
- Configuration is designed to work with Modbus-485 protocol for industrial applications
## FEATURES
- Automatic platform detection (ESP32, Portenta H7, Controllino Mega, Arduino Uno)
- Component ID enumeration for consistent system-wide component identification
- Configurable GPIO pin assignments for various peripherals
- Network configuration for WiFi in both station and access point modes
- Modbus TCP and RS485 communication settings
- Temperature profile and signal plotting configuration
- Customizable debugging and logging options
- Feature flags for enabling/disabling system components
## DEPENDENCIES
- [Arduino.h](https://www.arduino.cc/reference/en/) - Core Arduino library
- [config_adv.h](../src/config_adv.h) - Advanced configuration settings
- [stdint.h](https://en.cppreference.com/w/cpp/header/cstdint) - Standard integer types
```mermaid
graph TD
config[config.h] --> arduino[Arduino.h]
config --> configadv[config_adv.h]
config --> stdint[stdint.h]
config --> platformlibs[Platform-specific Libraries]
```
## BEHAVIOUR
The configuration system is a static definition file that controls the behavior of the firmware at compile time. It doesn't have runtime behavior itself, but dictates which components are initialized and how they operate.
```mermaid
graph TD
Config[Configuration System] --> PlatformDetection[Platform Detection]
Config --> ComponentIDs[Component ID Assignment]
Config --> FeatureFlags[Feature Flags]
FeatureFlags --> EnabledComponents[Enabled Components]
FeatureFlags --> DisabledComponents[Disabled Components]
Config --> NetworkSettings[Network Settings]
Config --> PinAssignments[Pin Assignments]
```
## TODOS
### PERFORMANCE
- Consider separating platform-specific configurations into dedicated files
- Evaluate the impact of enabled debugging flags on performance
- Review pin assignment efficiency for optimal GPIO usage
### SECURITY
- WiFi credentials are hardcoded - implement secure storage or configuration mechanism
- Consider encryption for sensitive communications
- Review and secure default access point settings
### COMPLIANCE
- Review for compliance with industrial standards
- Consider adding provisions for safety-critical systems where applicable
- Document electrical specifications for compliance with relevant regulations
### RECOMMENDATIONS
- Use preprocessor guards when modifying to ensure backward compatibility
- When adding new components, follow the existing ID assignment pattern
- Consider implementing a runtime configuration system to complement static definitions
- Separate network credentials into a separate secure file
## EXAMPLE
The configuration system is used primarily as an include in other components. For example, when initializing an LED Feedback component:
```cpp
#ifdef PIN_LED_FEEDBACK_0
ledFeedback_0 = new LEDFeedback(
this, // owner
PIN_LED_FEEDBACK_0, // pin
LED_PIXEL_COUNT_0, // pixelCount
ID_LED_FEEDBACK_0, // id
LED_FEEDBACK_0_MB_ADDR // modbusAddress
);
if (ledFeedback_0)
{
components.push_back(ledFeedback_0);
Log.infoln(F("LEDFeedback_0 initialized. Pin:%d, Count:%d, ID:%d, MB:%d"),
PIN_LED_FEEDBACK_0, LED_PIXEL_COUNT_0,
ID_LED_FEEDBACK_0, LED_FEEDBACK_0_MB_ADDR);
}
else
{
Log.errorln(F("LEDFeedback_0 initialization failed."));
}
#endif
```
