Modbus For Android

Introduce

This is a Modbus library for Android.

How to use

1.Add the library to your project

compile files('libs/modbus4Android-1.0.jar')

Copy the jar to the lib directory of your project and add the config to build.gradle.

2.Create and init ModbusReq instance

ModbusReq.getInstance().setParam(new ModbusParam()
                .setHost("192.168.0.105")
                .setPort(502)
                .setEncapsulated(false)
                .setKeepAlive(true)
                .setTimeout(2000)
                .setRetries(0))
                .init(new OnRequestBack<String>() {
            @Override
            public void onSuccess(String s) {
                Log.d(TAG, "onSuccess " + s);
            }

            @Override
            public void onFailed(String msg) {
                Log.d(TAG, "onFailed " + msg);
            }
        });

Init ModbusReq instance through setting the modbus param.

3.Read Coil

ModbusReq.getInstance().readCoil(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);

                        Log.d(TAG, "readDiscreteInput onSuccess " + Arrays.toString(booleen));
                    }

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

                    @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);

 ModbusReq.getInstance().readInputRegisters(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);

                        Log.e(TAG, "writeCoil onFailed " + msg);
                    }
                },1,1,true);

                    @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

                    @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

ModbusReq.getInstance().destroy();

Extends

if you use RTU Mode with SerialPort,you should do :

• 1. Create a class to implement SerialPortWrapper interface.
• 2. Create a ModbusMaster instance with createRtuMaster mothod of ModbusFactory class.
