Usage

[Serializable]
public class Test12
{
    public int AA1 { get; set; }
    public int AA2 { get; set; }
    public int AA3 { get; set; }
    public int AA4 { get; set; }
    public int AA5 { get; set; }
    public int AA6 { get; set; }
    public int AA7 { get; set; }
    public int AA8 { get; set; }
}

public static void Main(string[] args)
{
    //initialize controller
    using (var controller = new Controller("10.155.128.192", "1, 0", CPUType.LGX))
    {
        //ping controller
        Console.Out.WriteLine("Ping " + controller.Ping(true));

        //create group tag
        var grp = controller.CreateGroup();

        //add tag
        var tag = grp.CreateTagType<string[]>("Track", TagSize.STRING, 300);
        tag.Changed += TagChanged;
        var value = tag.Read();

        //add tag from Class
        var tag1 = grp.CreateTagType<Test12>("Test");
        tag.Changed += TagChanged;

        var tag2 = grp.CreateTagFloat32("Fl32");

        grp.Changed += GroupChanged;
        grp.Read();

    }
}

private static void PrintChange(string @event, ResultOperation result)
{
  Console.Out.WriteLine($"{@event} {result.Timestamp} Changed: {result.Tag.Name}");
}

static void TagChanged(ResultOperation result)
{
  PrintChange("TagChanged", result);
}

static void GroupChanged(IEnumerable<ResultOperation> results)
{
  foreach (var result in results) PrintChange("GroupTagChanged", result);
}

Create Tag

It is possible to create a tag of any type:

  • CreateTagInt64
  • CreateTagUInt64
  • CreateTagInt32
  • CreateTagUInt32
  • CreateTagInt16
  • CreateTagUInt16
  • CreateTagInt8
  • CreateTagUInt8
  • CreateTagString
  • CreateTagFloat32
  • CreateTagFloat64
  • CreateTagType specify type and name only, and automatically calculated size from property or array
  • CreateTagType specify name,size,length for array
  • CreateTagArray

Sizes are specified in TagSize.

For arrays specify the size in the definition.

Example:

public class TestArray
{
  public int InTest { get; set; }
  public int[] InTestArray { get; set; } = new int[5];
  public string[] StringTestArray { get; set; } = new string[300];
}

Custom types are classes. The properties are read sequentially.
