Android端使用Modbus协议的简单方法

        ModbusReq.getInstance().setParam(ModbusParam()
                .setHost(salveIP)//从站的IP地址
                .setPort(salvePort)//从站的端口
                .setEncapsulated(false)//
                .setKeepAlive(true)
                .setTimeout(2000)
                .setRetries(0))
                .init(object : OnRequestBack<String> {
                    override fun onSuccess(t: String?) {
                   
                    }

                    override fun onFailed(msg: String?) {
                      
                    }
                })

读保持寄存器
/**
 * Function Code 3
 * Read Holding Registers
 *
 * @param onRequestBack callback
 * @param slaveId       slave id 从站id
 * @param start         start address 读取保持寄存器的开始位置
 * @param len           length 读取的数据长度
 */

 ModbusReq.getInstance().readHoldingRegisters(object : OnRequestBack<ShortArray> {
            @SuppressLint("SetTextI18n")
            override fun onSuccess(t: ShortArray?) {//这个就是读取到的数据
            
            }

            override fun onFailed(msg: String?) {
                
            }
        }, slaveId, shart, len)

/**
 * Function Code 16
 * Write Registers
 *
 * @param onRequestBack callback
 * @param slaveId       slave id
 * @param start         start address
 * @param values        values
 */

 ModbusReq.getInstance().writeRegisters(object : OnRequestBack<String> {
            override fun onSuccess(s: String) {

            }

            override fun onFailed(msg: String) {
            
            }
        }, slaveId, start, shortArray)
        

读线圈
/**
 * Function Code 1
 * Read Coil Register
 *
 * @param onRequestBack callback
 * @param slaveId       slave id
 * @param start         start address
 * @param len           length
 */

ModbusReq.getInstance().readCoil(object :OnRequestBack<BooleanArray>{
    override fun onSuccess(t: BooleanArray?) {
       
    }

    override fun onFailed(msg: String?) {
       
    }
},1,1,10)

ModbusReq.getInstance().writeCoils(object :OnRequestBack<String>{
    override fun onFailed(msg: String?) {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }

    override fun onSuccess(t: String?) {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }
},1,1, arrayOf(true,true,false,false).toBooleanArray())

ModbusReq.getInstance().destory()

var modbusSlave=TcpSlave(502,false)//默认端口502，不开启压缩儿
modbusSlave.addProcessImage(BasicProcessImage(1))//初始化数据存储的镜像，
modbusSlave.start()//关闭服务 stop方法
