+====== Use of this connection ======
+**RTS2** provides connection for working with Modbus TCP/IP protocol. The advantage of this connection is that it inherits from Rts2Conn, and so can be easily integrated into Rts2 as another connection. There is a sample code how to use it:
+<code c++>
+class Zelio:public Rts2Sensor
+{
+	private:
+		HostString *host;
+		rts2core::ConnModbus *zelioConn;
+	protected:
+		virtual int processOption (int in_opt);
+	public:
+		Zelio (int argc, char **argv);
+		virtual ~Zelio (void);
+		virtual int init ();
+		virtual int info ();
+};
+}
+int
+Zelio::processOption (int in_opt)
+{
+	switch (in_opt)
+	{
+		// process hoststring (port can be specified after :)
+		case 'z':
+			host = new HostString (optarg, "502");
+			break;
+		default:
+			return Rts2Sensor::processOption (in_opt);
+	}
+	return 0;
+}
+Zelio::Zelio (int argc, char **argv)
+:Rts2Sensor (argc, argv)
+{
+	host = NULL;
+	addOption ('z', NULL, 1, "Zelio TCP/IP address and port (separated by :)");
+}
+Zelio::~Zelio (void)
+{
+	delete zelioConn;
+	delete host;
+}
+int
+Zelio::info ()
+{
+	// call Modbus TCP/IP coild query
+	zelioConn->readCoils (0, 8);
+	return Rts2Sensor::info ();
+}
+int
+Zelio::init ()
+{
+	int ret = Rts2Sensor::init ();
+	if (ret)
+		return ret;
+	zelioConn = new rts2core::ConnModbus (this, host->getHostname (), host->getPort ());
+	return zelioConn->init ();
+}
+int
+main (int argc, char **argv)
+{
+	Zelio device = Zelio (argc, argv);
+	return device.run ();
+}
