Client Api Allen-Bradley PLC (Made in Italy)
Note: PLCs control many kinds of equipment and loss of property, production or even life can happen if mistakes in programming or access are made. Always use caution when accessing or programming PLCs!
We make no claims or warrants about the suitability of this code for any purpose.
Be careful!
The client is wrapper of LibTagPLC library.
- Open source
- Controller implementation
- Native Tag type INT8, UINT8, INT16, UINT16, INT32, UINT32, INT64, UINT64, FLOAT32, FLOAT64, STRING
- Custom class definition structure
- Manipulation local value variable
- Read and Write with advanced result
- Time execution
- Status code
- Timestamp
- Tag
- Value property decode value natively
- Lock/Unlock for thread operation
- Decode Error StatusCodeOperation.DecodeError()
- Group interval read/write
- Event result Tag and TagGroup with result changed value
- Enable "Fail Operation Raise Exception" (default: false)
- Value Manager directly modify
- Bit manipulation
- Debug level
- Auto Read/Write when using value (default: false)
- Native support 32/64 bit for Windows/Linux
[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;

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

{
PrintChange("TagChanged", result);
}
static void GroupChanged(IEnumerable<ResultOperation> results)
{
foreach (var result in results) PrintChange("GroupTagChanged", result);
}
Are possible to create any tag:
- 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
Size are specified in TagSize.
For array specify size in 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 type are class. The properties are read sequentially.
