title: Default ping timeout
body: <p>What is the default time of ping? I use the code below to send ping to tcp devices. When does IPStatus fall to timeout?</p>
  
  <pre><code>private static void ApplyPing(Topology.Runtime rt)
  {
      try
      {
          if (rt.TcpClient != null)
          {
              string ip = rt.Ip;
              if (new Ping().Send(ip).Status != IPStatus.Success)
              {
                  Service.WriteEventLog(string.Format("{0} ping error.", ip), EventLogEntryType.Warning);
                  rt.Disconnect();
              }
          }
      }
      catch (ArgumentNullException ex)
      { 
  
      }
      catch (Exception ex)
      {
          Service.WriteEventLog(ex, EventLogEntryType.Error);
      }
  }
  </code></pre>
  
  <p>Thank you.</p>
