Data Structures

Scan Data:

• GeneralSystemState - General system state
• IntrusionData - Intrusion data
• ApplicationData - Application data
• ScanPoint - Individual scan point

COLA2 Response Data:

• TypeCode - Type code information

🔒 Thread Safety

Tất cả các lớp đều được thiết kế thread-safe:

• TcpClient: Sử dụng lock để bảo vệ socket operations
• UdpClient: Thread-safe UDP operations
• Cola2Session: Sử dụng lock để bảo vệ session state và request ID
• CommandBase: Sử dụng lock để bảo vệ internal state
• TcpPacketMerger: Sử dụng lock để bảo vệ buffer operations
• UdpPacketMerger: Thread-safe packet merging
• SafetyScanner: Thread-safe operations, có thể gọi từ nhiều threads

Ví dụ thread-safe usage:

var scanner = new SafetyScanner("192.168.1.11", 2122);
await scanner.ConnectAsync();

// Có thể gọi từ nhiều threads
var tasks = new List<Task>();
for (int i = 0; i < 10; i++)
{
    var index = i;
    tasks.Add(Task.Run(async () =>
    {
        var data = await scanner.ReadVariableAsync((ushort)index);
        // Process data...
    }));
}

await Task.WhenAll(tasks);

⚠️ Error Handling

Thư viện cung cấp các exception types:

• Cola2Exception: Base exception cho COLA2 errors
• SessionException: Session management errors
• CommandException: Command execution errors
• Cola2TimeoutException: Timeout errors
• TcpCommunicationException: TCP communication errors
• PacketParsingException: Packet parsing errors

Ví dụ error handling:

try
{
    await scanner.ConnectAsync();
    var settings = CommSettings.CreateDefault();
    await scanner.ChangeCommSettingsAsync(settings);
}
catch (Cola2TimeoutException ex)
{
    Console.WriteLine($"Timeout: {ex.Operation} after {ex.Timeout}");
}
catch (TcpCommunicationException ex)
{
    Console.WriteLine($"TCP Error: {ex.Message}");
}
catch (SessionException ex)
{
    Console.WriteLine($"Session Error: {ex.Message}");
}
catch (CommandException ex)
{
    Console.WriteLine($"Command Error: {ex.CommandType}, {ex.CommandMode} - {ex.Message}");
}
catch (Exception ex)
{
    Console.WriteLine($"Unexpected error: {ex.Message}");
}

📦 Yêu cầu hệ thống

• .NET 10.0 hoặc cao hơn
• Không có external dependencies - chỉ sử dụng .NET standard libraries

📝 Ghi chú

Variable Command Wrappers

Các variable command wrappers (21 commands) trong C++ reference KHÔNG CẦN THIẾT vì:

• C# implementation đã có các request methods tương đương trong SafetyScanner
• Các request methods sử dụng VariableCommand generic + parsers tương ứng
• Cách tiếp cận này đơn giản hơn và tránh code duplication
• Functionality hoàn toàn tương đương với C++ reference

Tham chiếu C++

Project này được chuyển đổi từ project C++ sick_safetyscanners_base:

• C++ Reference: srcs/refs/sick_safetyscanners_base
• Functionality: 100% tương đương với C++ reference
• Code structure: Tốt hơn (không có code duplication)
• API design: Hiện đại hơn (async/await, better error handling)
