安卓 通过modbus 控制plc

modbus是一种串行通信协议，通过modbus从而达到控制plc的目的，现在的主流 也俨然成为了工业领域的通信标准。

modbus是一对一：一主一从 主发从回     一对多也可以但是也是一对一的模式 同时不能多个；如果支持广播 那么就是一对多  主发送 从不响应那种了 这种情况通信查询国标GBT 19582-2

一主多从通信，主机通过从机ID号来区分要通信的从机设备。从机ID范围为1~247，0为广播地址，248~255为用户自定义地址

modbus分为有线和无线，我大概是需要用到无线 

现在的4种通信形式分别为：RTU、ASCII、TCP、Plus

我学习tcp形式

TCP是一种网络协议，而Modbus/TCP就是基于网络协议上的一种应用层协议。其报文格式是十六进制的，由报头（2字节的帧序号+2字节的协议类型+2字节的数据长度+1字节的Slave ID）+数据两部分组成。由于该通信方式是基于TCP/IP这种可靠协议上，所以通信不需要有额外的校验机制。

安卓使用modbus tcp 简单通过网络查询到的使用方法

注意：PLC端需要开启Modbus TCP Server

引入

创建连接

/**
     * 初始化plc链接
     * @param modbusIp
     * @param modbusPort
     */
    public static void initModubusTCP(String modbusIp,Integer modbusPort){
        ModbusReq.getInstance().setParam(new ModbusParam()
                .setHost("192.168.124.189")
                .setPort(502)
                .setEncapsulated(false)
                .setKeepAlive(true)
                .setTimeout(2000)
                .setRetries(0))
                .init(new OnRequestBack<String>() {
                    @Override
                    public void onSuccess(String s) {
                        Log.d("modbus", "onSuccess " + s);
                    }
 
                    @Override
                    public void onFailed(String msg) {
                        Log.d("modbus", "onFailed " + msg);
                    }
                });
    }

 

读取线圈数据：读取slaveId = 1；数据地址为VB10001开始，向后5位的数据；

ModbusReq.getInstance().readDiscreteInput(new OnRequestBack<boolean[]>() {
                @Override
                public void onSuccess(boolean[] booleen) {
                    Log.d("modbus", "readDiscreteInput onSuccess " + Arrays.toString(booleen));
                }
 
                @Override
                public void onFailed(String msg) {
                    Log.e("modbus", "readDiscreteInput onFailed " + msg);
                }
            },1,1,5);

 

写数据：向slaveId = 1，PLC地址为VB10001,中写入开关量：false（0）

ModbusReq.getInstance().writeCoil(new OnRequestBack<String>() {
                @Override
                public void onSuccess(String s) {
                    Log.e("modbus", "writeCoil onSuccess " + s);
                }
 
                @Override
                public void onFailed(String msg) {
                    Log.e("modus", "writeCoil onFailed " + msg);
                }
            },1,1,false);

其它读写类型可参考modbus4android中的readme文件

 

最后一定记得回收

ModbusReq.getInstance().destory()

modbus 可以添加物理设备去实现无线替换有线的情况
