# XINJE Modbus RTU Neuron XINJE Modbus RTU 插件使用 Modbus RTU 协议，用于采集信捷 PLC 标签的数据，支持信捷 XC/XD/XL 系列 PLC 型号。 ## 添加插件 在 **配置 -> 南向设备**，点击**添加设备**来创建设备节点，输入插件名称，插件类型选择 **XINJE Modbus RTU** 启用插件。 ## 设备配置 点击插件卡片或插件列，进入**设备配置**页。配置 Neuron 与设备建立连接所需的参数，下表为插件相关配置项。 |
参数
| 说明 | | -------------------- | ---------------------------------------------------------------------------------------------- | | **PLC 型号** | 选择信捷 PLC 型号。 | | **物理链路** | 选择使用 Serial （串口）或者是 Ethernet（以太网）通信介质。 | | **连接超时时间** | 等待设备返回指令响应的时间。 | | **最大重试次数** | 发送读取指令失败后最大重试次数。 | | **指令重新发送间隔** | 发送读取指令失败后重新发送读指令时间间隔，单位为毫秒。 | | **指令发送间隔** | 发送每条读写指令之间的等待时间。某些串口设备在较短时间内接收到连续指令时，可能会丢弃某些指令。 | | **字节序** | 32 位数据类型字节序，ABCD 对应 1234。 | | **串口设备** | 串口模式下，串口设备的路径，如 Linux 系统中 /dev/ttyS0。 | | **停止位** | 串口模式下，串口连接参数。 | | **校验位** | 串口模式下，串口连接参数。 | | **波特率** | 串口模式下，串口连接参数。 | | **数据位** | 串口模式下，串口连接参数。 | | **连接模式** | Ethernet 模式下，可以选择 Neuron 作为 TCP 的客户端或是服务端。 | | **IP 地址** | Ethernet 模式下，设备的 IP 地址（Neuron 作为客户端）；或是 Neuron 本机的 IP 地址（Neuron 作为服务端），默认可填 0.0.0.0。 | | **端口** | Ethernet 模式下，设备的端口号（Neuron 作为客户端）；或是 Neuron 本机的端口（Neuron 作为服务端）。| | **最大重试次数** | 发送读取指令失败后最大重试次数。 | | **指令重新发送间隔** | 发送读取指令失败后重新发送读指令时间间隔，单位为毫秒。 | XINJE Modbus RTU 插件的配置与 [Modbus RTU驱动模块](../modbus-rtu/modbus-rtu.md)相似。 ## 设置组和点位 完成插件的添加和配置后，要建立设备与 Neuron 之间的通信，首先为南向驱动程序添加组和点位。 完成设备配置后，在**南向设备**页，点击设备卡片/设备列进入**组列表**页。点击**创建**来创建组，设定组名称以及采集间隔。完成组的创建后，点击组名称进入**点位列表**页，添加需要采集的设备点位，包括点位地址，点位属性，数据类型等。 公共配置项部分可参考[连接南向设备](../south-devices.md)，本页将介绍支持的数据类型和地址格式部分。 ### 数据类型 * INT16 * UINT16 * INT32 * UINT32 * INT64 * UINT64 * FLOAT * DOUBLE * BIT * STRING * BYTES ### 地址格式 > SLAVE!ADDRESS\[.BIT][#ENDIAN]\[.LEN\[H]\[L]\[D]\[E]]\[.BYTES] #### **SLAVE** 必填，指从机地址或者是站点号。 #### **ADDRESS** 信捷 PLC 将内存数据单元（输入/输出继电器、定时器、计数器等）映射到 Modbus 地址空间，以通过 Modbus RTU 协议进行访问。 根据 PLC 型号，此类地址映射可能会有所不同。 Neuron XINJE Modbus RTU 插件将 PLC 数据单元名称指定为 **ADDRESS**，用户不需要关心地址映射的细节。 用户可以根据 PLC 型号从[信捷官方文档](https://m.xinje.com/xj_service/xj_xzzx.html)中查看地址映射的细节。 为了方便起见，以下表格将其列在这里。 ::: warning 注意 X 和 Y 区域的数据单元使用八进制进行编号。 例如，对于XC1/XC2/XC3/XC5/XCM/XCC PLC 型号： * X0~X7：对应于Modbus地址空间中的 16384~16384+7。 * X10~X17：对应于Modbus地址空间中的 16384+8~16384+15。 * X70~X77：对应于Modbus地址空间中的 16384+56~16384+63。 ::: *

------------------------------- | | D4.0 | bit | PLC 数据寄存器 D4，第 0 位。 | | D10.4 | bit | PLC 数据寄存器 D4，第 4 位。 | | D1.15 | bit | PLC 数据寄存器 D1，第 15 位。 | #### **#ENDIAN** 选填，字节顺序，适用于 int16/uint16/int32/uint32/float 数据类型，详细说明见下表。 | 符号 | 字节顺序 | 支持的数据类型 | 备注 | | ---- | -------- | ------------------ | ------------------ | | #B | 2,1 | int16/uint16 | | | #L | 1,2 | int16/uint16 |

点位字节序优先级高于节点字节序配置。即点位配置字节序后，字节序按照点位的配置，忽略节点配置。 字节顺序可能用 ABCD 表示，只需将 1234 对应 ABCD 即可。例如 ABCD 对应默认字节序 1234 (#LL)。 ::: #### .LEN\[H]\[L]\[D]\[E] 当数据类型为 STRING 类型时，**.LEN** 是必填项，表示字符串需要占用的字节长度，每个寄存器中包含**H**，**L**，**D** 和**E** 四种存储方式，如下列表格所示。 | 符号 | 说明 | | ---- | ---------------------------------------------- | | H | 一个寄存器存储两个字节，高字节在前低字节在后。 | | L | 一个寄存器存储两个字节，低字节在前高字节在后。 | | D | 一个寄存器存储一个字节，且存储在低字节。 | | E | 一个寄存器存储一个字节，且存储在高字节。 | #### **.BYTES** 选填，读写bytes类型数据的长度，适用于 bytes 数据类型。 ::: tip Modbus 驱动的一个寄存器包含 2 个 bytes，在以 bytes 数据类型读取和写入 Modbus 寄存器数据时，请保证 bytes 参数设置为偶数。
