CTR Class (COUNTER) A class that represents the entire Allen-Bradley COUNTER structure from a type 'C' data table.

For a list of all members of this type, see CTR Members.

System.Object
   ABLink.CTR

Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

To read/write a Counter element (e.g "C5:0.ACC") specific the element name in the Tag.Name (e.g Tag.Name = "C5:0.ACC") For a detailed description of the COUNTER structure please refer to the appropriate Allen-Bradley programmable logic controller instruction manual.

Example

VB
' ************************
' * initialize controller and tag
Dim MyPLC as New ABLink.Controller("192.168.1.32")
Dim MyTag as New ABLink.Tag("C5:0")

' ***********************
' * create a CTR class
Dim MyCTR As ABLink.CTR

Try
  ' ***********************
  ' * read the tag
  MyPLC.ReadTag(MyTag)

  If ResultCode.QUAL_GOOD = MyTag.QualityCode Then
    ' **********************
    ' * assign .Value to CTR class
    MyCTR = MyTag.Value
    Console.WriteLine(MyCTR.ACC.ToString())
    Console.WriteLine(MyCTR.PRE.ToString())
  End If
    
Catch ex As System.Exception
  Console.WriteLine(ex.Message)
End Try    

C#
///////////////////////////////////
// initialize controller and tag class
ABLink.Controller MyPLC = new Controller("192.168.1.32");
ABLink.Tag MyTag = new ABLink.Tag("C5:0");

try
{
   /////////////////////////////////
   // read the tag
   MyPLC.ReadTag(MyTag);
   
   if (ABLink.ResultCode.QUAL_GOOD == MyTag.QualityCode)
   {
     // assign .Value to CTR class
     ABLink.CTR MyCTR = (ABLink.CTR)MyTag.Value;
     Console.WriteLine(MyCTR.ACC.ToString());
     Console.WriteLine(MyCTR.PRE.ToString());
   }
}
catch(System.Exception ex)
{
   Console.WriteLine(ex.Message);
}
