特性 6 | 7 | - 支持 Modbus TCP 和 Modbus RTU 通信协议。 8 | - 提供了灵活的数据读写接口，包括读取和写入线圈、输入状态、保持寄存器和输入寄存器等功能。 9 | - 支持自定义寄存器地址、数据类型和数据长度。 10 | - 提供了异常处理机制，用于处理 Modbus 从站返回的错误信息。 11 | - 支持多线程操作，可同时处理多个 Modbus 请求。 12 | - 简化了 Modbus 通信的实现细节，减少了开发时间和复杂性。 13 | 14 | ## 安装 15 | 16 | 你可以通过以下方式获取该框架： 17 | 18 | - 下载源代码并手动集成到你的项目中。 19 | - 使用 Maven 或 Gradle 等构建工具，将该框架添加为依赖项。 20 | 21 | ```groovy 22 | allprojects { 23 | repositories { 24 | maven { url 'https://jitpack.io' } 25 | } 26 | } 27 | 28 | dependencies { 29 | implementation 'com.github.hzlaoliu:modbus:1.0.0' 30 | } 31 | ``` 32 | 33 | ## 使用示例 34 | 35 | 下面是一个简单的示例代码，展示了如何使用 Modbus Master 框架进行数据读取: 36 | 37 | #### 初始化 38 | 39 | * 该框架只做 modbus 的数据协议处理，不做链路层的链接。需要自行链接，并用 `inputStream` 和 `outputStream` 初始化框架 40 | 41 | ```kotlin 42 | //RTU模式 43 | val serialPort = SerialPort(File("/dev/ttyS1"), 115200, 1, 8, 0, 0, 0) 44 | modeBus = ModbusMaster.init(ModBusMaserConfig(ModBusMode.RTU), serialPort.inputStream, serialPort.outputStream) 45 | modeBus?.onReceive() 46 | 47 | //TCP模式 48 | val socket = Socket("192.168.0.1", 5020) 49 | modeBus = ModbusMaster.init(ModBusMaserConfig(ModBusMode.TCP), socket.getInputStream(), socket.getOutputStream()) 50 | modeBus?.onReceive() 51 | ``` 52 | 53 | #### 支持的读写 54 | 55 | ```kotlin 56 | /** 读 0x01 ，线圈*/ 57 | fun createRequestRead01(slaveId: Byte, start: Int, num: Int): ReadCoilsRequest = ReadCoilsRequest(slaveId, start, num) 58 | 59 | /** 读 0x02 ，离散寄存器*/ 60 | fun createRequestRead02(slaveId: Byte, start: Int, num: Int): ReadDiscreteRequest = ReadDiscreteRequest(slaveId, start, num) 61 | 62 | /** 读 0x03 ，保持寄存器*/ 63 | fun createRequestRead03(slaveId: Byte, start: Int, num: Int): ReadHoldRegisterRequest = ReadHoldRegisterRequest(slaveId, start, num) 64 | 65 | /** 读 0x04 ，输入寄存器*/ 66 | fun createRequestRead04(slaveId: Byte, start: Int, num: Int): ReadInputRegisterRequest = ReadInputRegisterRequest(slaveId, start, num) 67 | 68 | /** 写 0x05 ，单个线圈*/ 69 | fun createRequestWrite05(slaveId: Byte, start: Int, value: Boolean): WriteCoilOneRequest = WriteCoilOneRequest(slaveId, start, value) 70 | 71 | /** 写 0x06，单个寄存器*/ 72 | fun createRequestWrite06(slaveId: Byte, start: Int, value: Short): WriteRegisterOneRequest = WriteRegisterOneRequest(slaveId, start, value) 73 | 74 | /** 写 0x10 ,多个寄存器*/ 75 | fun createRequestWrite10(slaveId: Byte, start: Int, values: ShortArray): WriteRegistersRequest = WriteRegistersRequest(slaveId, start, values) 76 | 77 | /** 写 0x0f ，多个线圈*/ 78 | fun createRequestWrite0f(slaveId: Byte, start: Int, values: BooleanArray): WriteCoilsRequest = WriteCoilsRequest(slaveId, start, values) 79 | ``` 80 | 81 | #### 读示例 82 | 83 | ```kotlin 84 | lifecycleScope.launch(Dispatchers.IO) { 85 | //读取从站 =1 的线圈，从0开始读取100个 86 | val response = modeBus?.read(ModbusMaster.createRequestRead01(1, 0, 100)) 87 | Log.d("TAG", "返回的原始数据 ${response?.raw}") 88 | Log.d("TAG", "返回的 BooleanArray 类型的 result ${response?.result}") 89 | } 90 | 91 | lifecycleScope.launch(Dispatchers.IO) { 92 | //读取从站 =1 的保持寄存器，从0开始读20个 93 | val response = modeBus?.read(ModbusMaster.createRequestRead03(1, 0, 20)) 94 | Log.d("TAG", "返回的原始数据 ${response?.raw}") 95 | Log.d("TAG", "返回的 ShortArray 类型的 result ${response?.result}") 96 | } 97 | ``` 98 | 99 | #### 写示例 100 | 101 | ```kotlin 102 | lifecycleScope.launch(Dispatchers.IO) { 103 | //写从站 =1 的多个寄存器，从200开始写入 [98,25,33] 这三个数据 104 | val response = modeBus?.write(ModbusMaster.createRequestWrite10(1, 200, shortArrayOf(98, 25, 33))) 105 | Log.d("TAG", "返回的原始数据 ${response?.raw}") 106 | Log.d("TAG", "返回的 ByteArray 类型的 pdu ${response?.pdu}") 107 | } 108 | ``` 109 | 110 | ##
