# DTS API Test Suite
|
||||
|
||||
A comprehensive test script for monitoring DTS (Desalination Treatment System) mode progression through the Watermaker PLC API. This tool starts DTS mode, monitors all screen transitions, tracks timer progress, and provides detailed debugging information.
|
||||
|
||||
## Features
|
||||
|
||||
- ✅ **Complete DTS Flow Monitoring**: Tracks all 5 DTS screens (Requested → Priming → Init → Production → Fresh Water Flush)
|
||||
- ⏱️ **Timer Progress Tracking**: Monitors countdown timers and calculates progress percentages
|
||||
- 🔄 **Transition Detection**: Detects and logs when the controller advances between screens
|
||||
- 📊 **Detailed Logging**: Structured logging with timestamps and comprehensive context
|
||||
- 📈 **Performance Analysis**: Tracks API response times and system performance
|
||||
- 🚨 **Error Detection**: Identifies stuck timers, timeouts, and API communication issues
|
||||
- 📄 **Multiple Report Formats**: JSON logs, CSV data export, and console summaries
|
||||
|
||||
## DTS Flow Overview
|
||||
|
||||
The test monitors the complete DTS process through these screens:
|
||||
|
||||
1. **DTS Requested (Mode 34)** - Initial request state
|
||||
2. **Priming (Mode 5)** - Timer R128 (180 seconds) - Flush with shore pressure
|
||||
3. **Init (Mode 6)** - Timer R129 (60 seconds) - High pressure pump initialization
|
||||
4. **Production (Mode 7)** - No timer - Water flowing to tank
|
||||
5. **Fresh Water Flush (Mode 8)** - Timer R133 (60 seconds) - Process ending
|
||||
6. **Complete (Mode 2)** - Return to standby
|
||||
|
||||

### Generated Files
|
||||
|
||||
The test creates several output files:
|
||||
|
||||
```
|
||||
logs/
|
||||
├── dts_test_20250111_181200.log # Detailed log file
|
||||
|
||||

|
||||
├── dts_timer_data_20250111_181200.csv # Timer progress data
|
||||
```
|
||||
|
||||
## API Endpoints Used
|
||||
|
||||
The test interacts with these API endpoints:
|
||||
|
||||
- `GET /api/system/status` - Check system health
|
||||
- `POST /api/dts/start` - Start DTS sequence
|
||||
- `GET /api/dts/status/{task_id}` - Monitor task progress
|
||||
- `GET /api/dts/current-step-progress` - Get real-time timer info
|
||||
- `POST /api/dts/stop` - Emergency stop (if needed)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### API Connection Failed
|
||||
```
|
||||
❌ System status: Failed to connect
|
||||
```
|
||||
**Solution**: Ensure the API server is running on the correct port:
|
||||
```bash
|
||||
python run_server.py
|
||||
```
|
||||
|
||||
#### DTS Sequence Won't Start
|
||||
```
|
||||
❌ Failed to start DTS sequence
|
||||
```
|
||||
**Possible causes**:
|
||||
- Another DTS operation is already running
|
||||
- PLC is not in a valid starting mode
|
||||
- PLC connection issues
|
||||
|
||||
**Check current status**:
|
||||
```bash
|
||||
curl http://localhost:5000/api/dts/status
|
||||
```
|
||||
|
||||
#### Stuck Timer Detected
|
||||
```
|
||||
⚠️ Timer R128 appears stuck at 1500
|
||||
```
|
||||
**Solution**: This indicates a potential PLC communication issue or the timer isn't counting down as expected. Check PLC connection and system logs.
|
||||
|
||||
#### Slow Transitions
|
||||
```
|
||||
⚠️ Slow transition: 4m 30s (expected ~3m 0s)
|
||||
```
|
||||
**Solution**: This is informational - the system is working but slower than expected. May indicate system load or PLC performance issues.
|
||||
|
||||
### Debug Mode
|
||||
|
||||
For detailed debugging, run with verbose output:
|
||||
```bash
|
||||
python dts_api_test_suite.py --verbose
|
||||
```
|
||||
|
||||
This will show:
|
||||
- All API requests and responses
|
||||
- Detailed timer value changes
|
||||
- Internal state transitions
|
||||
- Performance metrics
|
||||
|
||||
### Log Analysis
|
||||
|
||||
Check the generated log files in the `logs/` directory for detailed information:
|
||||
|
||||
```bash
|
||||
# View latest log
|
||||
ls -la logs/
|
||||
tail -f logs/dts_test_*.log
|
||||
```
|
||||
|
||||
## Integration with CI/CD
|
||||
|
||||
The test script returns appropriate exit codes:
|
||||
- `0` - Test passed successfully
|
||||
- `1` - Test failed
|
||||
|
||||
Example integration:
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Run DTS API test
|
||||
python dts_api_test_suite.py --config config/ci_test_config.json
|
||||
|
||||
if [ $? -eq 0 ]; then
|
||||
echo "✅ DTS API tests passed"
|
||||
else
|
||||
echo "❌ DTS API tests failed"
|
||||
exit 1
|
||||
fi
|
||||
```
|
||||
|
||||
## Development
|
||||
|
||||
### Adding New Features
|
||||
|
||||
The test suite is designed to be extensible:
|
||||
|
||||
1. **Custom Analyzers**: Add new analysis functions in the `DTSAPITester` class
|
||||
2. **Additional Reports**: Extend the `generate_reports()` method
|
||||
3. **New Configurations**: Add options to the `TestConfig` class
|
||||
4. **Custom Endpoints**: Add new API endpoint methods
|
||||
|
||||
### Testing the Test Suite
|
||||
|
||||
To test the test suite itself without running a full DTS cycle:
|
||||
|
||||
```bash
|
||||
# Test API connectivity only
|
||||
python -c "
|
||||
from dts_api_test_suite import DTSAPITester
|
||||
tester = DTSAPITester()
|
||||
print('✅ Connected' if tester.check_system_status() else '❌ Failed')
|
||||
"
|
||||
```
|
||||
|
||||
## Support
|
||||
|
||||
For issues or questions:
|
||||
|
||||
1. Check the generated log files for detailed error information
|
||||
2. Verify API server is running and accessible
|
||||
3. Ensure PLC connection is stable
|
||||
4. Review configuration settings
|
||||
|
||||
The test suite provides comprehensive logging and error reporting to help diagnose any issues with the DTS API or PLC communication.

# DTS API Test Script - Implementation Plan
|
||||
|
||||
## Overview
|
||||
This document outlines the comprehensive test script for monitoring DTS mode progression through the API. The script will start DTS mode, monitor all screen transitions, track timer progress, and provide detailed debugging information.
|
||||
|
||||
## Architecture
|
||||
|
||||
### Core Components
|
||||
|
||||
#### 1. DTSAPITester Class
|
||||
```python
|
||||
class DTSAPITester:
|
||||
"""Main test orchestrator for DTS API testing"""
|
||||
|
||||
def __init__(self, api_base_url="http://localhost:5000/api", config=None):
|
||||
self.api_base_url = api_base_url
|
||||
self.config = config or TestConfig()
|
||||
self.logger = self._setup_logger()
|
||||
self.session = requests.Session()
|
||||
self.current_task_id = None
|
||||
self.transition_history = []
|
||||
self.start_time = None
|
||||
self.test_results = TestResults()
|
||||
```
|
||||
|
||||
#### 2. API Client Methods
|
||||
```python
|
||||
def start_dts_sequence(self) -> dict:
|
||||
"""Start DTS sequence via API POST /api/dts/start"""
|
||||
|
||||
def get_task_status(self, task_id: str) -> dict:
|
||||
"""Get task status via GET /api/dts/status/{task_id}"""
|
||||
|
||||
def get_current_step_progress(self) -> dict:
|
||||
"""Get real-time progress via GET /api/dts/current-step-progress"""
|
||||
|
||||
def stop_dts_sequence(self) -> dict:
|
||||
"""Emergency stop via POST /api/dts/stop"""
|
||||
```
|
||||
|
||||
#### 3. Monitoring & Analysis
|
||||
```python
|
||||
def monitor_dts_progress(self):
|
||||
"""Main monitoring loop - polls API and detects transitions"""
|
||||
|
||||
def detect_screen_transition(self, current_state: dict, previous_state: dict) -> bool:
|
||||
"""Detect when controller advances to next screen"""
|
||||
|
||||
def log_transition_event(self, transition: TransitionEvent):
|
||||
"""Log detailed transition information"""
|
||||
|
||||
def analyze_timer_progress(self, timer_info: dict):
|
||||
"""Analyze timer countdown and progress"""
|
||||
```
|
||||
|
||||
## DTS Flow Monitoring
|
||||
|
||||
### Screen Sequence
|
||||
1. **DTS Requested (Mode 34)** - No timer, user interaction required
|
||||
2. **Priming (Mode 5)** - Timer R128 (180 seconds)
|
||||
3. **Init (Mode 6)** - Timer R129 (60 seconds)
|
||||
4. **Production (Mode 7)** - No timer, continuous operation
|
||||
5. **Fresh Water Flush (Mode 8)** - Timer R133 (60 seconds)
|
||||
6. **Complete (Mode 2)** - Return to standby
|
||||
|
||||
### Transition Detection Logic
|
||||
```python
|
||||
# Mode mapping for screen identification
|
||||
SCREEN_MODES = {
|
||||
34: "dts_requested_active",
|
||||
5: "dts_priming_active",
|
||||
6: "dts_init_active",
|
||||
7: "dts_production_active",
|
||||
8: "dts_flush_active",
|
||||
2: "dts_process_complete"
|
||||
}
|
||||
|
||||
# Timer mappings for progress tracking
|
||||
TIMER_MAPPINGS = {
|
||||
5: {"timer_address": 128, "expected_duration": 180, "name": "Priming"},
|
||||
6: {"timer_address": 129, "expected_duration": 60, "name": "Init"},
|
||||
8: {"timer_address": 133, "expected_duration": 60, "name": "Fresh Water Flush"}
|
||||
}
|
||||
```
|
||||
|
||||
## API Endpoints Used
|
||||
|
||||
### Primary Endpoints
|
||||
- `POST /api/dts/start` - Initiate DTS sequence
|
||||
- `GET /api/dts/status/{task_id}` - Monitor task progress
|
||||
- `GET /api/dts/current-step-progress` - Real-time timer info
|
||||
|
||||
### Supporting Endpoints
|
||||
- `GET /api/system/status` - System health check
|
||||
- `POST /api/dts/stop` - Emergency stop capability
|
||||
- `POST /api/dts/cancel/{task_id}` - Cancel specific task

# DTS Single State Refactoring - Completion Summary
|
||||
|
||||
## Overview
|
||||
Successfully implemented the DTS Single State Refactoring Plan, transforming the DTS controller from a task_id-based system to a single operation state model. This refactoring eliminates unnecessary complexity while maintaining all existing functionality.
|
||||
|
||||
## ✅ Completed Implementation
|
||||
|
||||
### 1. Core Infrastructure ✅
|
||||
- **Created `OperationStateManager`** in `watermaker_plc_api/services/operation_state.py`
|
||||
- Thread-safe single operation state management
|
||||
- Operation lifecycle management (start, update, complete, cancel)
|
||||
- Operation history tracking (last 10 operations)
|
||||
- Conflict detection for concurrent operations
|
||||
|
||||
### 2. DTS Controller Refactoring ✅
|
||||
- **Updated imports** to use the new operation state manager
|
||||
- **Removed task_id system** - eliminated `dts_operations = {}` dictionary
|
||||
- **Refactored core functions**:
|
||||
- `update_dts_progress_from_timers()` - now uses single state
|
||||
- `execute_dts_sequence()` - no longer requires task_id parameter
|
||||
- `execute_stop_sequence()` - simplified state management
|
||||
- `execute_skip_sequence()` - streamlined operation flow
|
||||
- `handle_external_dts_change()` - replaces old task creation functions
|
||||
|
||||
### 3. API Endpoints Modernization ✅
|
||||
- **Simplified status endpoint**: `/api/dts/status` (no task_id required)
|
||||
- **Updated control endpoints**: Return `operation_id` instead of `task_id`
|
||||
- **Backward compatibility**: Legacy endpoints still work but route to new system
|
||||
- **Improved cancel endpoint**: `/api/dts/cancel` (no task_id required)
|
||||
|
||||
### 4. External Change Handling ✅
|
||||
- **Updated background tasks** to use operation state manager
|
||||
- **Integrated R1000 monitor** with new state system
|
||||
- **Unified external/API operations** - both use same state model
|
||||
|
||||
### 5. Progress Monitoring ✅
|
||||
- **Simplified timer updates** - single operation instead of dictionary iteration
|
||||
- **Enhanced state tracking** - better progress and error reporting
|
||||
- **Consistent data structure** across all operation types
|
||||
|
||||
## 📊 Benefits Achieved
|
||||
|
||||
### Code Simplification
|
||||
- **Before**: 1,158 lines in `dts_controller.py`
|
||||
- **After**: ~1,188 lines (includes new features and better error handling)
|
||||
- **Complexity Reduction**: Eliminated task dictionary management and iteration
|
||||
|
||||
### Performance Improvements
|
||||
- ✅ **No dictionary iterations** for conflict checking
|
||||
- ✅ **Single state access** instead of task lookups
|
||||
- ✅ **Reduced memory usage** - no unbounded dictionary growth
|
||||
- ✅ **Faster status access** - direct state retrieval
|
||||
|
||||
### API Simplification
|
||||
- ✅ **Single status endpoint**: `/api/dts/status`
|
||||
- ✅ **No task_id management** for clients
|
||||
- ✅ **Immediate status access** without task tracking
|
||||
- ✅ **Cleaner response format** with operation metadata
|
||||
|
||||
### Unified Architecture
|
||||
- ✅ **External and API operations** use same state model
|
||||
- ✅ **No separate monitoring tasks** for external changes
|
||||
- ✅ **Consistent progress tracking** across all operation types
|
||||
- ✅ **Thread-safe state management** with proper locking
|
||||
|
||||
## 🔄 Backward Compatibility
|
||||
|
||||
### Legacy Endpoints Maintained
|
||||
- `/api/dts/status/<task_id>` - routes to current state
|
||||
- `/api/dts/cancel/<task_id>` - cancels current operation
|
||||
- All existing response formats preserved
|
||||
|
||||
### Migration Path
|
||||
- Existing clients continue to work without changes
|
||||
- New clients can use simplified endpoints
|
||||
- Gradual migration possible without service disruption
|
||||
|
||||

# DTS Single State Refactoring Plan
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document outlines a comprehensive plan to refactor the DTS controller from a task_id-based system to a single operation state model. The current system uses multiple task tracking for a PLC that can only run one mode at a time, creating unnecessary complexity.
|
||||
|
||||
## Current Architecture Analysis
|
||||
|
||||
### Problems with Task_ID System
|
||||
1. **Unnecessary Complexity**: Managing dictionary of tasks when only one can run
|
||||
2. **Resource Overhead**: Indefinite growth of `dts_operations` dictionary
|
||||
3. **Conflict Detection**: Must iterate through all tasks to find running operations
|
||||
4. **External Monitoring**: Creates separate tasks for externally-initiated operations
|
||||
5. **Client Complexity**: Requires task_id tracking for status polling
|
||||
|
||||
### Current Code Structure
|
||||
```python
|
||||
# Current approach - multiple task tracking
|
||||
dts_operations = {} # Dictionary grows indefinitely
|
||||
task_id = str(uuid.uuid4())[:8]
|
||||
dts_operations[task_id] = {...}
|
||||
|
||||
# Conflict checking requires iteration
|
||||
for task in dts_operations.values():
|
||||
if task["status"] == "running":
|
||||
return False, "Operation already in progress"
|
||||
```
|
||||
|
||||
## Proposed Single State Architecture
|
||||
|
||||
### Core Principle
|
||||
**One PLC Mode = One API State**
|
||||
|
||||
Since the PLC can only be in one operational mode at a time, the API should maintain a single operation state that reflects the current reality.
|
||||
|
||||
### State Model Design
|
||||
|
||||
```mermaid
|
||||
stateDiagram-v2
|
||||
[*] --> Idle
|
||||
Idle --> Running : Start Operation
|
||||
Running --> Completed : Success
|
||||
Running --> Failed : Error
|
||||
Running --> Cancelled : User Cancel
|
||||
Completed --> Idle : Auto Reset
|
||||
Failed --> Idle : Auto Reset
|
||||
Cancelled --> Idle : Auto Reset
|
||||
|
||||
note right of Running
|
||||
Single operation state
|
||||
No task_id needed
|
||||
Direct status access
|
||||
end note
|
||||
```
|
||||
|
||||
### New Data Structure
|
||||
|
||||
```python
|
||||
# Single global operation state
|
||||
current_dts_operation = {
|
||||
"status": "idle", # idle, running, completed, failed, cancelled

|
||||
#### Step 1.2: Update DTS Controller Structure
|
||||
**File**: `watermaker_plc_api/controllers/dts_controller.py`
|
||||
|
||||
**Changes Required:**
|
||||
1. Replace `dts_operations = {}` with state manager
|
||||
2. Remove task_id generation and management
|
||||
3. Simplify conflict checking
|
||||
4. Update all operation functions
|
||||
|
||||
### Phase 2: Refactor Core Functions
|
||||
|
||||
#### Step 2.1: Simplify Operation Starters
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
def start_dts_sequence_async():
|
||||
# Check if another operation is running
|
||||
for task in dts_operations.values():
|
||||
if task["status"] == "running":
|
||||
return False, "Operation already in progress", {"existing_task_id": task["task_id"]}
|
||||
|
||||
# Create new task
|
||||
task_id = create_dts_task()
|
||||
|
||||
# Start background thread
|
||||
thread = threading.Thread(target=execute_dts_sequence, args=(task_id,), daemon=True)
|
||||
thread.start()
|
||||
|
||||
return True, "DTS sequence started", {"task_id": task_id}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
def start_dts_sequence_async():
|
||||
state_manager = get_operation_state_manager()
|
||||
|
||||
# Attempt to start operation
|
||||
success, message, details = state_manager.start_operation("dts_start", "api")
|
||||
if not success:
|
||||
return False, message, details
|
||||
|
||||
# Start background thread
|
||||
thread = threading.Thread(target=execute_dts_sequence, daemon=True)
|
||||
thread.start()
|
||||
|
||||
return True, message, details
|
||||
```
|
||||
|
||||
#### Step 2.2: Simplify Execution Functions
|
||||
|
||||
**Before:**
|
||||
```python

||||
def execute_dts_sequence(task_id):
|
||||
task = dts_operations[task_id]
|
||||
try:
|
||||
task["status"] = "running"
|
||||
task["start_time"] = datetime.now().isoformat()
|
||||
# ... execution logic
|
||||
except Exception as e:
|
||||
task["status"] = "failed"
|
||||
# ... error handling
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
def execute_dts_sequence():
|
||||
state_manager = get_operation_state_manager()
|
||||
try:
|
||||
state_manager.update_state({
|
||||
"current_step": "checking_system_mode",
|
||||
"progress_percent": 0
|
||||
})
|
||||
# ... execution logic
|
||||
state_manager.complete_operation(success=True)
|
||||
except Exception as e:
|
||||
state_manager.complete_operation(success=False, error_msg=str(e))
|
||||
```
|
||||
|
||||
### Phase 3: Update API Endpoints
|
||||
|
||||
#### Step 3.1: Simplify Status Endpoint
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
@dts_bp.route('/dts/status')
|
||||
@dts_bp.route('/dts/status/<task_id>')
|
||||
def get_dts_status(task_id=None):
|
||||
if task_id:
|
||||
task = dts_operations.get(task_id)
|
||||
if not task:
|
||||
return create_error_response("Not Found", f"Task {task_id} not found", 404)
|
||||
return jsonify({"task": task})
|
||||
else:
|
||||
latest_task = get_latest_dts_task()
|
||||
return jsonify({"latest_task": latest_task})
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
@dts_bp.route('/dts/status')
|
||||
def get_dts_status():
|
||||
"""Get current DTS operation status"""
|
||||
state_manager = get_operation_state_manager()
|
||||
|
||||
# Update progress from timers for running operations
|
||||
if state_manager.is_running():
|
||||
update_dts_progress_from_timers()
|
||||
|
||||
current_state = state_manager.get_current_state()
|
||||
|
||||
# Add user-friendly descriptions
|
||||
descriptions = current_state.get("screen_descriptions", {})
|
||||
current_state["screen_description"] = descriptions.get(
|
||||
current_state["current_step"],
|
||||
current_state["current_step"]
|
||||
)
|
||||
current_state["is_complete"] = current_state["status"] in ["completed", "failed", "cancelled"]
|
||||
current_state["is_running"] = current_state["status"] == "running"
|
||||
|
||||
return jsonify({
|
||||
"operation": current_state,
|
||||
"timestamp": datetime.now().isoformat()
|
||||
})
|
||||
|
||||
# Backward compatibility endpoint
|
||||
@dts_bp.route('/dts/status/<task_id>')
|
||||
def get_dts_status_legacy(task_id):
|
||||
"""Legacy endpoint for backward compatibility"""
|
||||
# Always return current state regardless of task_id
|
||||
return get_dts_status()
|
||||
```
|
||||
|
||||
#### Step 3.2: Simplify Control Endpoints
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
@dts_bp.route('/dts/start', methods=['POST'])
|
||||
def start_dts():
|
||||
success, message, details = start_dts_sequence_async()
|
||||
if success:
|
||||
return create_success_response(message, {
|
||||
"task_id": details["task_id"],
|
||||
"status_endpoint": f"/api/dts/status/{details['task_id']}"
|
||||
}, 202)
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
@dts_bp.route('/dts/start', methods=['POST'])
|
||||
def start_dts():
|
||||
success, message, details = start_dts_sequence_async()
|
||||
if success:
|
||||
return create_success_response(message, {
|
||||
"operation_id": details["operation_id"],
|
||||
"status_endpoint": "/api/dts/status",

"polling_info": {
|
||||
"recommended_interval": "1 second",
|
||||
"check_status_at": "/api/dts/status"
|
||||
}
|
||||
}, 202)
|
||||
else:
|
||||
return create_error_response("Conflict", message, 409, details)
|
||||
```
|
||||
|
||||
### Phase 4: Update External Change Handling
|
||||
|
||||
#### Step 4.1: Integrate with R1000 Monitor
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
def create_external_dts_monitoring_task(change_info):
|
||||
task_id = str(uuid.uuid4())[:8]
|
||||
dts_operations[task_id] = {
|
||||
"task_id": task_id,
|
||||
"status": "running",
|
||||
"external_origin": True,
|
||||
# ... more fields
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
def handle_external_dts_change(change_info):
|
||||
state_manager = get_operation_state_manager()
|
||||
|
||||
# If no operation running, start external monitoring
|
||||
if state_manager.is_idle():
|
||||
success, message, details = state_manager.start_operation("external_monitoring", "external")
|
||||
if success:
|
||||
state_manager.update_state({
|
||||
"current_step": f"dts_mode_{change_info['new_value']}",
|
||||
"current_mode": change_info["new_value"],
|
||||
"external_changes": [change_info],
|
||||
"note": f"External DTS process detected - monitoring mode {change_info['new_value']}"
|
||||
})
|
||||
else:
|
||||
# Add to existing operation's external changes
|
||||
current_state = state_manager.get_current_state()
|
||||
external_changes = current_state.get("external_changes", [])
|
||||
external_changes.append(change_info)
|
||||
state_manager.update_state({"external_changes": external_changes})
|
||||
```
|
||||
|
||||
### Phase 5: Update Progress Monitoring
|
||||
|
||||
#### Step 5.1: Simplify Timer-Based Updates
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
def update_dts_progress_from_timers():
|
||||
for task_id, task in dts_operations.items():
|
||||
if task["status"] == "running":
|
||||
# Update each task individually
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
def update_dts_progress_from_timers():
|
||||
state_manager = get_operation_state_manager()
|
||||
|
||||
if not state_manager.is_running():
|
||||
return
|
||||
|
||||
current_state = state_manager.get_current_state()
|
||||
|
||||
# Read current system mode
|
||||
current_mode = plc.read_holding_register(1000)
|
||||
if current_mode is None:
|
||||
return
|
||||
|
||||
# Update progress based on current mode and timers
|
||||
updates = {"current_mode": current_mode}
|
||||
|
||||
# Get timer-based progress
|
||||
timer_address = get_timer_for_dts_mode(current_mode)
|
||||
if timer_address:
|
||||
current_timer_value = plc.read_holding_register(timer_address)
|
||||
timer_progress = get_timer_based_progress(current_mode)
|
||||
|
||||
updates.update({
|
||||
"progress_percent": timer_progress,
|
||||
"timer_info": {
|
||||
"current_mode": current_mode,
|
||||
"timer_address": timer_address,
|
||||
"timer_progress": timer_progress,
|
||||
"raw_timer_value": current_timer_value,
|
||||
"timer_active": current_timer_value is not None and current_timer_value != 65535,
|
||||
"last_updated": datetime.now().isoformat()
|
||||
}
|
||||
})
|
||||
|
||||
# Check for completion (back to standby)
|
||||
if current_mode == 2: # Standby mode
|
||||
state_manager.complete_operation(success=True)
|
||||
updates["note"] = "DTS process completed - system in standby mode"
|
||||
|
||||
state_manager.update_state(updates)
|
||||
```
|
||||
|
||||
## Migration Strategy
|
||||
|
||||
### Phase A: Backward Compatibility (Week 1)
|
||||
1. Implement new state manager alongside existing system

# R1000 Monitoring System Documentation
|
||||
|
||||
## Overview
|
||||
|
||||
The R1000 monitoring system has been implemented to watch for changes in the PLC's R1000 register (system mode) that could be made by external HMI systems bypassing the API. This addresses the requirement that "The external HMI could advance the step, cancel the process or start a different process."
|
||||
|
||||
## Architecture
|
||||
|
||||
### Components
|
||||
|
||||
1. **R1000Monitor Class** (`watermaker_plc_api/services/background_tasks.py`)
|
||||
- Continuously monitors R1000 register for changes
|
||||
- Classifies change types (Process Start, Process Stop, Step Skip, etc.)
|
||||
- Maintains callback system for change notifications
|
||||
- Stores change history in data cache
|
||||
|
||||
2. **BackgroundTaskManager Integration**
|
||||
- R1000Monitor is integrated into the existing background task system
|
||||
- Runs alongside regular PLC data updates
|
||||
- Handles change callbacks and impact assessment
|
||||
|
||||
3. **DTS Controller Enhancements** (`watermaker_plc_api/controllers/dts_controller.py`)
|
||||
- Enhanced to detect external changes during DTS operations
|
||||
- Tracks external changes in running tasks
|
||||
- Provides API endpoint for monitoring status
|
||||
|
||||
## Key Features
|
||||
|
||||
### Change Detection
|
||||
- **Continuous Monitoring**: R1000 is checked every data update cycle (configurable interval)
|
||||
- **Change Classification**: Automatically categorizes changes based on mode transitions
|
||||
- **External Change Assumption**: All changes are initially assumed to be external until proven otherwise
|
||||
|
||||
### Change Types Detected
|
||||
- **Process_Start**: System starting DTS process (Standby → DTS_Priming or DTS_Requested)
|
||||
- **Process_Stop**: System stopping DTS process (any DTS mode → Standby)
|
||||
- **Step_Skip**: Skipping DTS step (Priming/Init → Production)
|
||||
- **Step_Advance**: Advancing DTS step (Priming/Init/Production → Flush)
|
||||
- **DTS_Start**: DTS process beginning (DTS_Requested → DTS_Priming)
|
||||
- **Mode_Change**: Other mode transitions
|
||||
|
||||
### Impact on Running Tasks
|
||||
- **External Change Tracking**: Running DTS tasks are marked when external changes occur
|
||||
- **Step Change Detection**: Enhanced logging when steps advance due to external changes
|
||||
- **External Stop Detection**: Special handling when DTS process is stopped externally
|
||||
- **Automatic Task Creation**: When R1000 changes to a DTS mode without existing API tasks, a monitoring task is automatically created
|
||||
|
||||
### External Task Management
|
||||
- **Automatic Detection**: System detects when PLC enters DTS mode externally (without API initiation)
|
||||
- **Task Creation**: Automatically creates monitoring tasks for externally-initiated DTS processes
|
||||
- **Full Monitoring**: External tasks receive the same monitoring capabilities as API-initiated tasks
|
||||
- **Origin Tracking**: Tasks are clearly marked as externally-initiated vs API-initiated
|
||||
|
||||
## API Endpoints

|
||||
## Implementation Details
|
||||
|
||||
### R1000Monitor Class Methods
|
||||
|
||||
#### `check_r1000_changes()`
|
||||
- Reads current R1000 value from PLC
|
||||
- Compares with last known value
|
||||
- Triggers callbacks and logging on changes
|
||||
- Updates internal tracking variables
|
||||
|
||||
#### `_classify_change(old_value, new_value)`
|
||||
- Analyzes mode transition patterns
|
||||
- Returns descriptive change type string
|
||||
- Maps numeric modes to human-readable names
|
||||
|
||||
#### `add_change_callback(callback)`
|
||||
- Registers callback functions for change notifications
|
||||
- Used by BackgroundTaskManager to handle change impacts
|
||||
|
||||
#### `create_external_dts_monitoring_task(change_info)`
|
||||
- Creates monitoring tasks for externally-initiated DTS processes
|
||||
- Called automatically when R1000 enters DTS mode without existing API tasks
|
||||
- Returns task_id for the new monitoring task
|
||||
|
||||
### Integration Points
|
||||
|
||||
#### Background Task Loop
|
||||
```python
|
||||
# Monitor R1000 for external changes
|
||||
self.r1000_monitor.check_r1000_changes()
|
||||
```
|
||||
|
||||
#### DTS Task Impact Handling
|
||||
```python
|
||||
def _handle_r1000_change(self, change_info):
|
||||
"""Handle R1000 changes detected by the monitor"""
|
||||
# Log warning about external change
|
||||
# Check if external DTS process started without API task
|
||||
# Create monitoring task if needed
|
||||
# Check impact on running DTS tasks
|
||||
# Mark affected tasks with change information
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Monitoring Frequency
|
||||
The R1000 monitoring frequency is tied to the `Config.DATA_UPDATE_INTERVAL` setting, which controls how often the background task loop runs.
|
||||
|
||||
### Error Retention
|
||||
R1000 changes are stored in the data cache error list, with retention controlled by `Config.MAX_CACHED_ERRORS`.
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Starting the Monitoring System
|
||||
The R1000 monitoring starts automatically when background tasks are started:
|
||||
|
||||
```python
|
||||
from watermaker_plc_api.services.background_tasks import start_background_updates
|
||||
start_background_updates()
|
||||
```
|
||||
|
||||
### Accessing Monitor Status
|
||||
```python
|
||||
from watermaker_plc_api.services.background_tasks import get_r1000_monitor
|
||||
|
||||
monitor = get_r1000_monitor()
|
||||
current_value = monitor.get_current_r1000()
|
||||
last_change = monitor.get_last_change_time()
|
||||
```
|
||||
|
||||
### API Usage
|
||||
```bash
|
||||
# Get current monitoring status
|
||||
curl http://localhost:5000/api/dts/r1000-monitor
|
||||
|
||||
# Get DTS status with external change information
|
||||
curl http://localhost:5000/api/dts/status
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Script
|
||||
A comprehensive test script `test_r1000_monitoring.py` is provided to demonstrate the monitoring functionality:
|
||||
|
||||
```bash
|
||||
python test_r1000_monitoring.py
|
||||
```
|
||||
|
||||
The test script:
|
||||
1. Checks initial R1000 monitor status
|
||||
2. Starts a DTS process to create a running task
|
||||
3. Monitors for external changes over time
|
||||
4. Shows impact on running DTS tasks
|
||||
5. Provides final status summary
|
||||
|
||||
### Manual Testing
|
||||
1. Start the watermaker API server
|
||||
2. Run the test script or use API endpoints directly
|
||||
3. Use external HMI or PLC interface to change R1000 value
|
||||
4. Observe detection and classification of changes
|
||||
5. Check impact on any running DTS tasks
|
||||
|
||||
## Logging
|
||||
|
||||
### Log Levels and Messages
|
||||
|
||||
#### INFO Level
|
||||
- Initial R1000 value detection

|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **External Change Detection**: Automatically detects when external systems modify the PLC mode
|
||||
2. **Process Integrity**: Helps maintain awareness of process state changes not initiated by the API
|
||||
3. **Debugging Support**: Provides detailed logging and history of mode changes
|
||||
4. **Task Impact Tracking**: Shows how external changes affect running API operations
|
||||
5. **Real-time Monitoring**: Continuous monitoring provides immediate notification of changes
|
||||
6. **Classification System**: Intelligent categorization of change types for better understanding
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
1. **Change Prediction**: Could be enhanced to predict likely next states
|
||||
2. **Conflict Resolution**: Could implement strategies for handling conflicts between API and external changes
|
||||
3. **Change Validation**: Could validate whether changes are appropriate for current system state
|
||||
4. **Historical Analysis**: Could provide trends and patterns in external changes
|
||||
5. **Alert System**: Could implement configurable alerts for specific change types
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **No Changes Detected**: Check PLC connection and background task status
|
||||
2. **False Positives**: Verify that API operations are properly marked as internal
|
||||
3. **Missing Changes**: Check monitoring frequency and PLC response time
|
||||
4. **Callback Errors**: Review callback function implementations for exceptions
|
||||
|
||||
### Diagnostic Commands
|
||||
```bash
|
||||
# Check if background tasks are running
|
||||
curl http://localhost:5000/api/system/status
|
||||
|
||||
# Get R1000 monitoring status

## DTS Modes
|
||||
|
||||
The watermaker system operates through various DTS (Desalination Treatment System) modes controlled by register R1000. Understanding these modes is essential for UI modeling and system monitoring.
|
||||
|
||||
### System Mode Values (R1000)
|
||||
|
||||
| Mode | Name | Description | Timer | Duration |
|
||||
|------|------|-------------|-------|----------|
|
||||
| 65535 | Standby/Screen Saver | System in standby mode | - | - |
|
||||
| 2 | Idle/Home | System idle at home screen | - | - |
|
||||
| 3 | Alarm List | Displaying system alarms | - | - |
|
||||
| 34 | DTS Requested | Step 1 - Press and hold DTS to START | - | Manual |
|
||||
| 5 | DTS Step 1 | Step 2 - Flush with shore pressure | R138 | 15 sec |
|
||||
| 6 | DTS Step 2 | Step 3 - High pressure pump on, product valve divert | R128 | 180 sec |
|
||||
| 7 | DTS Production | Step 4 - High pressure pump on, water flowing to tank | - | Variable |
|
||||
| 8 | Fresh Water Flush | Post-production flush sequence | R133 | 60 sec |
|
||||
| 9 | Setup Screen | System configuration interface | R135 | 10 sec |
|
||||
| 10 | DTS Step 6 | Final flush sequence | R139 | 60 sec |

|
||||
| 33 | Seawater Home | Pick single or double pass | - | Manual |
|
||||
|
||||
### DTS Process Flow
|
||||
|
||||
The typical DTS watermaker sequence follows this progression:
|
||||
|
||||
1. **Mode 34** → **Mode 5** → **Mode 6** → **Mode 7** → **Mode 8** → **Mode 10** → **Mode 2**
|
||||
|
||||
### Timer Mappings
|
||||
|
||||
Each DTS step with a timer has specific register addresses and expected durations:
|
||||
|
||||
| Timer Register | DTS Mode | Step Name | Expected Duration | Purpose |
|
||||
|----------------|----------|-----------|-------------------|---------|
|
||||
| R138 | 5 | DTS Step 1 | 15 seconds | Initial processing |
|
||||
| R128 | 6 | DTS Step 2 | 180 seconds | Priming sequence |
|
||||
| R133 | 8 | DTS Step 4 | 60 seconds | Processing |
|
||||
| R135 | 9 | DTS Step 5 | 10 seconds | Stop sequence |
|
||||
| R139 | 10 | DTS Step 6 | 60 seconds | Final flush |
|
||||
|
||||
**Note**: Mode 7 (Production) has no timer as it runs until manually stopped or conditions change.
|
||||
|
||||
### Control Operations by Mode
|
||||
|
||||
Different stop sequences are executed based on the current mode:
|
||||
|
||||
- **Mode 5**: R71=512 → R71=0 → R1000=8
|
||||
- **Mode 7**: R71=513 → R71=0 → R1000=8
|
||||
- **Mode 8**: R71=1024 → R71=0 → R1000=2
|
||||
|
||||
### Skip Operations
|
||||
|
||||
Skip functionality is available for specific modes:
|
||||
|
||||
- **From Mode 5**: Skip to Step 3 via R67=32841 (advances to Mode 6)
|
||||
- **From Mode 6**: Skip to Step 4 via R67=32968 → R1000=7
|
||||

||||
