// Create PLC connection
using var plc = new RxS7(CpuType.S71500, "192.168.1.100", rack: 0, slot: 1);

// Monitor connection status reactively
plc.IsConnected
    .Where(connected => connected)
    .Subscribe(_ => Console.WriteLine("✅ PLC Connected!"));

// Add tags for monitoring
plc.AddUpdateTagItem<float>("Temperature", "DB1.DBD0");
plc.AddUpdateTagItem<bool>("Running", "DB1.DBX4.0");

// Observe real-time data changes
plc.Observe<float>("Temperature")
    .Subscribe(temp => Console.WriteLine($"🌡️ Temperature: {temp:F1}°C"));

plc.Observe<bool>("Running")
    .Subscribe(running => Console.WriteLine($"⚙️ Running: {running}"));

📋 Core Functionality

🏷️ Tag Management

Adding Tags with Different Data Types

// Basic data types
plc.AddUpdateTagItem<bool>("MotorRunning", "DB1.DBX0.0");
plc.AddUpdateTagItem<byte>("Status", "DB1.DBB2");
plc.AddUpdateTagItem<short>("Counter", "DB1.DBW4");
plc.AddUpdateTagItem<int>("ProductCount", "DB1.DBD6");
plc.AddUpdateTagItem<float>("Temperature", "DB1.DBD10");
plc.AddUpdateTagItem<double>("Precision", "DB1.DBD14");

// Array types with specified lengths
plc.AddUpdateTagItem<byte[]>("ByteArray", "DB1.DBB100", length: 64);
plc.AddUpdateTagItem<float[]>("TemperatureArray", "DB1.DBD200", length: 10);

// Chainable tag creation
plc.AddUpdateTagItem<float>("Temp1", "DB1.DBD0")
   .AddUpdateTagItem<float>("Temp2", "DB1.DBD4")
   .AddUpdateTagItem<bool>("Alarm", "DB1.DBX8.0")
   .SetTagPollIng(false); // Disable polling on last tag

Tag Polling Control

// Add tag without automatic polling
var (tag, _) = plc.AddUpdateTagItem<float>("ManualRead", "DB1.DBD0")
                  .SetTagPollIng(false);

// Enable polling later
plc.GetTag("ManualRead").SetTagPollIng(true);

// Disable polling temporarily  
plc.GetTag("ManualRead").SetTagPollIng(false);

Tag Removal

// Remove specific tag
plc.RemoveTagItem("OldTag");

// Check if tag exists
if (plc.TagList.ContainsKey("Temperature"))
{
    var (tag, _) = plc.GetTag("Temperature");
    Console.WriteLine($"Tag found: {tag?.Name}");
}

📖 Reading Data

Reactive Data Observation

// Observe single tag changes
plc.Observe<float>("Temperature")
    .Where(temp => temp > 80.0f)
    .Subscribe(temp => Console.WriteLine($"🚨 High Temperature: {temp:F1}°C"));

// Observe multiple tags with filtering
plc.Observe<bool>("AlarmStatus")
    .Where(alarm => alarm)
    .Subscribe(_ => Console.WriteLine("🔔 ALARM TRIGGERED!"));

// Observe with time-based operations
plc.Observe<float>("Pressure")
    .Sample(TimeSpan.FromSeconds(5)) // Sample every 5 seconds
    .Subscribe(pressure => Console.WriteLine($"📊 Pressure: {pressure:F2} bar"));

// Buffer values for analysis
plc.Observe<float>("FlowRate")
    .Buffer(TimeSpan.FromMinutes(1))
    .Subscribe(values => 
    {
        var avg = values.Average();
        Console.WriteLine($"📈 Average Flow Rate (1min): {avg:F2} L/min");
    });

Manual Reading

// Read single values
var temperature = await plc.Value<float>("Temperature");
var isRunning = await plc.Value<bool>("Running");
var productCount = await plc.Value<int>("ProductCount");

Console.WriteLine($"Current Temperature: {temperature:F1}°C");
Console.WriteLine($"System Running: {isRunning}");
Console.WriteLine($"Products Made: {productCount}");

✏️ Writing Data

Direct Value Writing

// Write different data types
plc.Value("SetPoint", 75.5f);           // Float
plc.Value("Enable", true);              // Boolean  
plc.Value("RecipeNumber", 42);          // Integer
plc.Value("OperatorID", 1234);          // Word

// Write arrays
plc.Value("Recipe", new float[] { 25.0f, 50.0f, 75.0f });
plc.Value("ByteData", new byte[] { 0x01, 0x02, 0x03 });

Conditional Writing

// Write only when connected
plc.IsConnected
    .Where(connected => connected)
    .Subscribe(_ => 
    {
        plc.Value("Heartbeat", DateTime.Now.Ticks);
        plc.Value("SystemReady", true);
    });

📊 System Information

CPU Information

// Get CPU info reactively
plc.GetCpuInfo()
    .Subscribe(info => 
    {
        Console.WriteLine("📟 PLC Information:");
        Console.WriteLine($"  AS Name: {info[0]}");
        Console.WriteLine($"  Module: {info[1]}");
        Console.WriteLine($"  Serial: {info[3]}");
        Console.WriteLine($"  Order Code: {info[5]}");
        Console.WriteLine($"  Version: {info[6]} {info[7]} {info[8]}");
    });

// Get CPU info once
var cpuInfo = await plc.GetCpuInfo().FirstAsync();

🐕 Watchdog Configuration

Keep your PLC connection alive with automatic watchdog functionality:

// Create PLC with watchdog
var plc = new RxS7(
    cpuType: CpuType.S71500,
    ip: "192.168.1.100", 
    rack: 0,
    slot: 1,
    watchDogAddress: "DB100.DBW0",    // Must be DBW address
    interval: 100,                    // Polling interval (ms)
    watchDogValueToWrite: 4500,       // Watchdog value
    watchDogInterval: 10              // Watchdog write interval (seconds)
);

// Configure watchdog display
plc.ShowWatchDogWriting = true; // Show watchdog activity

// Monitor watchdog status
plc.Status
    .Where(status => status.Contains("WatchDog"))
    .Subscribe(status => Console.WriteLine($"🐕 {status}"));

⚡ Performance Optimizations

🚀 Batch Operations

Dramatically improve performance with intelligent batch operations:

using S7PlcRx.Performance;

// Batch reading - up to 10x faster
var tagNames = new[] { "Temp1", "Temp2", "Temp3", "Pressure1", "Flow1" };
var results = await plc.ReadOptimized<float>(tagNames);

foreach (var (tag, value) in results)
{
    Console.WriteLine($"{tag}: {value:F2}");
}

// Batch writing with verification
var writeValues = new Dictionary<string, float>
{
    ["SetPoint1"] = 75.5f,
    ["SetPoint2"] = 80.0f,
    ["SetPoint3"] = 65.0f
};

var config = new WriteOptimizationConfig
{
    EnableParallelWrites = true,
    VerifyWrites = true,
    InterGroupDelayMs = 10
};

var writeResult = await plc.WriteOptimized(writeValues, config);
Console.WriteLine($"✅ {writeResult.SuccessfulWrites.Count} writes completed");

📊 Performance Monitoring

// Monitor real-time performance
plc.MonitorPerformance(TimeSpan.FromSeconds(30))
    .Subscribe(metrics => 
    {
        Console.WriteLine($"📈 Performance Metrics:");
        Console.WriteLine($"  Operations/sec: {metrics.OperationsPerSecond:F1}");
        Console.WriteLine($"  Avg Response: {metrics.AverageResponseTime:F0}ms");
        Console.WriteLine($"  Error Rate: {metrics.ErrorRate:P2}");
        Console.WriteLine($"  Active Tags: {metrics.ActiveTagCount}");
    });

// Get performance statistics
var stats = plc.GetPerformanceStatistics();
Console.WriteLine($"Total Operations: {stats.TotalOperations}");
Console.WriteLine($"Connection Uptime: {stats.ConnectionUptime.TotalHours:F1}h");

🎯 Smart Caching

using S7PlcRx.Optimization;

// Enable intelligent caching
var cachedValue = await plc.ValueCached<float>("Temperature", TimeSpan.FromSeconds(1));

// Monitor cache performance
var cacheStats = plc.GetCacheStatistics();
Console.WriteLine($"Cache Hit Rate: {cacheStats.HitRate:P1}");
Console.WriteLine($"Cache Entries: {cacheStats.TotalEntries}");

// Clear cache when needed
plc.ClearCache();

🔍 Smart Tag Monitoring

Monitor only significant changes to reduce noise:

// Monitor with change threshold and debouncing
plc.MonitorTagSmart<float>("Temperature", changeThreshold: 0.5, debounceMs: 100)
    .Subscribe(change => 
    {
        Console.WriteLine($"🔔 Significant Change:");
        Console.WriteLine($"  Tag: {change.TagName}");
        Console.WriteLine($"  Previous: {change.PreviousValue:F2}");
        Console.WriteLine($"  Current: {change.CurrentValue:F2}");
        Console.WriteLine($"  Change: {change.ChangeAmount:F2}");
    });

🏭 Enterprise Features
