我通過以太網modbus tcp連接有問題。 我插入到AndroidManifest權限: 而我創建任務或連接和讀取Modbus。 我使用jamod庫。未連接modbus TCP
當我啓動應用程序給我一個連接失敗的錯誤。
這是我的代碼,我使用:
class Task implements Runnable {
@
Override
public void run() {
try {
ReadMultipleRegistersResponse result = null;
//Read And Write Register Sample
int port = Modbus.DEFAULT_PORT;
String refe = "4000"; //HEX Address
int ref = Integer.parseInt(refe, 16); //Hex to int
int count = 98; //the number Address to read
int SlaveAddr = 1;
String astr = "192.168.0.18"; //Modbus Device
InetAddress addr = InetAddress.getByName(astr);
TCPMasterConnection con = new TCPMasterConnection(addr);
ModbusTCPTransaction trans = null; //the transaction
//1.Prepare the request
/************************************/
ReadMultipleRegistersRequest Rreq = new ReadMultipleRegistersRequest(ref, count);
ReadMultipleRegistersResponse Rres = new ReadMultipleRegistersResponse();
Rreq.setUnitID(SlaveAddr); //set Slave Address
Rres.setUnitID(SlaveAddr); //set Slave Address
//2. Open the connection
con.setPort(port);
con.connect();
con.setTimeout(2500);
//3. Start Transaction
trans = new ModbusTCPTransaction(con);
trans.setRetries(5);
trans.setReconnecting(true);
trans.setRequest(Rreq);
trans.execute();
/*Print Response*/
Rres = (ReadMultipleRegistersResponse) trans.getResponse();
} catch (ModbusSlaveException me) {
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (java.lang.Exception e) {;
e.printStackTrace();
}
}
}
我在哪裏做錯了嗎?
那個ip地址是? – greenapps
