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，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
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。
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。

.BIT
选填，寄存器中的特定 bit，例如：
| 地址 | 数据类型 | 说明 |
|---|---|---|
| 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 | 不填，默认字节顺序 |
| #LL | 1,2,3,4 | int32/uint32/float | 不填，默认字节顺序 |
| #LB | 2,1,4,3 | int32/uint32/float | |
| #BL | 3,4,1,2 | int32/uint32/float | |
| #BB | 4,3,2,1 | int32/uint32/float |
TIP
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。
