Modbus Tcp for Android

Introduce

This is a Modbus TCP example for Android.If You need the examples for RTU/ASCII ,You can call me.

How to use

1.Create ModbusMaster

ModbusFactory factory = new ModbusFactory();
IpParameters params = new IpParameters();
//Setting Ip Address and port
params.setHost("192.168.0.101");
params.setPort(502);
params.setEncapsulated(false);
//Create ModbusMaster and set timeout and retry count
ModbusMaster master = factory.createTcpMaster(params, true);
// master.setRetries(4);
master.setTimeout(2000);
master.setRetries(0);

2.Init ModbusMaster

master.init();

3.Read Coil(Must in Child Thread)

ModbusReq.readCoil(mModbusMaster, new OnRequestBack<boolean[]>() {
                    @Override
                    public void onSuccess(boolean[] booleen) {
                        Log.d(TAG, "readCoil onSuccess " + Arrays.toString(booleen));
                    }

                    @Override
                    public void onFailed(String msg) {
                        Log.e(TAG, "readCoil onFailed " + msg);
                    }
                }, 1, 1, 2);

4.Read DiscreteInput(Must in Child Thread)

ModbusReq.readDiscreteInput(mModbusMaster, new OnRequestBack<boolean[]>() {
                    @Override
                    public void onSuccess(boolean[] booleen) {
                        Log.d(TAG, "readDiscreteInput onSuccess " + Arrays.toString(booleen));
                    }

                    @Override
                    public void onFailed(String msg) {
                        Log.e(TAG, "readDiscreteInput onFailed " + msg);
                    }
                },1,1,5);

5.Read HoldingRegisters(Must in Child Thread)

ModbusReq.readHoldingRegisters(mModbusMaster, new OnRequestBack<short[]>() {
                    @Override
                    public void onSuccess(short[] data) {
                        Log.d(TAG, "readHoldingRegisters onSuccess " + Arrays.toString(data));
                    }

                    @Override
                    public void onFailed(String msg) {
                        Log.e(TAG, "readHoldingRegisters onFailed " + msg);
                    }
                }, 1, 2, 8);

6.Read InputRegisters(Must in Child Thread)

 ModbusReq.readInputRegisters(mModbusMaster, new OnRequestBack<short[]>() {
                    @Override
                    public void onSuccess(short[] data) {
                        Log.d(TAG, "readInputRegisters onSuccess " + Arrays.toString(data));
                    }

                    @Override
                    public void onFailed(String msg) {
                        Log.e(TAG, "readInputRegisters onFailed " + msg);
                    }
                }, 1, 2, 8);

7.Write Coil(Must in Child Thread)

ModbusReq.writeCoil(mModbusMaster, new OnRequestBack<String>() {
                    @Override
                    public void onSuccess(String s) {
                        Log.e(TAG, "writeCoil onSuccess " + s);
                    }

                    @Override
                    public void onFailed(String msg) {
                        Log.e(TAG, "writeCoil onFailed " + msg);
                    }
                },1,1,true);

8.Write Register(Must in Child Thread)

ModbusReq.writeRegister(mModbusMaster, new OnRequestBack<String>() {
                    @Override
                    public void onSuccess(String s) {
                        Log.e(TAG, "writeRegister onSuccess " + s);
                    }

                    @Override
                    public void onFailed(String msg) {
                        Log.e(TAG, "writeRegister onFailed " + msg);
                    }
                },1,1,234);

9.Write Registers(Must in Child Thread)

ModbusReq.writeRegisters(mModbusMaster, new OnRequestBack<String>() {
                    @Override
                    public void onSuccess(String s) {
                        Log.e(TAG, "writeRegisters onSuccess " + s);
                    }

                    @Override
                    public void onFailed(String msg) {
                        Log.e(TAG, "writeRegisters onFailed " + msg);
                    }
                },1,2,new short[]{211,52,34});

10.Destroy Modbus Instance

master.destroy();
