+$ git clone https://github.com/emqx/neuron
+$ cd neuron && mkdir build && cd build
+$ cmake .. && make
+```
+
+3. Download and Unzip Dashboard
+```bash
+$ wget https://github.com/emqx/neuron-dashboard/releases/download/2.6.3/neuron-dashboard.zip
+
+# Unzip neuron-dashboard.zip to the build directory
+$ unzip neuron-dashboard.zip
+```
+
+4. Run Neuron
+```bash
+$ ./neuron --log
+```
+
+On the first startup, Neuron will automatically generate `neuron.key` and `neuron.key.pub` in the config directory if they do not exist yet.
+
+If you want to pre-generate the key pair manually, you can still run:
+
+```bash
+$ bash ./generate_rsa_keypair.sh ./build/config
+```
+
+5. Open a browser and navigate to `http://localhost:7000` to access the Neuron web interface.
+
+## Configuration

+# 数据上下行格式
+
+以下内容描述 MQTT 插件如何上报采集的数据，以及如何通过 MQTT 插件实现读写点位数据。
+
+
+## 数据上报
+
+MQTT 插件将采集到的数据以 JSON 形式发布到指定的主题。
+上报数据的具体格式由**上报数据格式**参数指定，有[**Values-format 格式**](#values-format-格式)、[**Tags-format 格式**](#tags-format-格式)、[**ECP-format 格式**](#ecp-format-格式)、[**Custom 自定义格式**](#custom-自定义格式)多种格式可选。
+
+### 上报主题
+
+上报主题在北向节点订阅中指定，其默认值为 **/neuron/{MQTT driver name}** ，见下图
+
+### Values-format 格式
+
+在 **Values-format** 格式中， 上报的数据由以下字段构成：
+* `timestamp` : 数据采集时的 UNIX 时间戳。
+* `node` : 被采集的南向节点的名字。
+* `group` : 被采集的南向节点的点位组的名字。
+* `values` : 存储采集成功的点位值的字典。
+* `errors` : 存储采集失败的错误码的字典。
+* `metas` : 驱动相关的元数据信息。
+
+以下为使用 **values-format** 格式的数据样例，采集成功的点位数据值存放在`values`键中，采集失败的点位错误码存放在`errors`键中。
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus",
+    "group": "grp",
+    "values":
+    {
+        "tag0": 123
+    },
+    "errors":
+    {
+        "tag1": 2014
+    },
+    "metas":{}
+}
+```
+
+::: tip 注意
+
+当点位采集成功时，返回采集到的数据。当点位采集发生错误时，返回错误码，不再返回数值。
+
+当 MQTT 插件配置项 **上报点位错误码** 为 **False** 时，不上报点位错误码。
+:::
+
+### Tags-format 格式
+
+在 **Tags-format** 格式中， 上报的数据由以下字段构成：
+* `timestamp` : 数据采集时的 UNIX 时间戳。
+* `node` : 被采集的南向节点的名字。
+* `group` : 被采集的南向节点的点位组的名字。
+* `tags` : 点位数据数组，每个元素对应一个点位。
+* `name` : 具体的点位名称字段。
+* `value` : 具体点位对应的值。
+* `error` : 具体点位对应的错误码。
+
+以下为使用 **Tags-format** 格式的数据样例，其中所有点位数据存放在一个数组中，每个数组元素包含点位的名字，采集成功时的数据值或者采集失败时的错误码。
+
+```json
+{
+  "timestamp": 1647497389075,
+  "node": "modbus",
+  "group": "grp",
+  "tags": [
+    {
+      "name": "tag0",
+      "value": 123,
+    },
+    {
+      "name": "tag1",
+      "error": 2014
+    }
+  ]
+}
+```
+
+::: tip 注意
+
+当点位采集成功时，返回采集到的数据。当点位采集发生错误时，返回错误码，不再返回数值。
+
+当 MQTT 插件配置项 **上报点位错误码** 为 **False** 时，不上报点位错误码。
+:::
+
+### ECP-format 格式
+
+在 **ECP-format** 格式中， 上报的数据由以下字段构成：
+* `timestamp` : 数据采集时的 UNIX 时间戳。
+* `node` : 被采集的南向节点的名字。
+* `group` : 被采集的南向节点的点位组的名字。
+* `tags` : 点位数据数组，每个元素对应一个点位。
+* `name` : 具体的点位名称字段。
+* `value` : 具体点位对应的值。
+* `type` : 具体点位对应的数据类型，共包含布尔、整型、浮点型、字符串四种数据类型。
+
+
+以下为使用 *ECP-format* 格式的数据样例，其中所有点位数据存放在一个数组中，每个数组元素包含点位的名字，点位的数据类型和采集成功时的数据值，不包含采集失败的点位。
+数据类分为布尔、整型、浮点型、字符串四种。
+* type = 1 布尔
+* type = 2 整型
+* type = 3 浮点型
+* type = 4 字符串
+
+```json
+{
+  "timestamp": 1647497389075,
+  "node": "modbus",
+  "group": "grp",
+  "tags": [
+    {
+      "name": "tag_boolean",
+      "value": true,
+      "type": 1,
+    },
+    {
+      "name": "tag_int32_",
+      "value": 123,
+      "type": 2,
+    },
+    {
+      "name": "tag_float",
+      "value": 1.23,
+      "type": 3,
+    },
+    {
+      "name": "tag_string",
+      "value": "abcd",
+      "type": 4,
+    }
+  ]
+}
+```
+
+::: tip 注意
+ECP-format 格式不支持上报点位错误码。
+不管 MQTT 插件配置项 **上报点位错误码** 为 **False** 或为 **True** ，都不上报点位错误码。
+:::
+
+### Custom 自定义格式
+
+在自定义格式中，可以使用内置支持的变量自定义数据上报格式。
+
+![custom-format](./assets/custom-format.png)
+
+#### 内置变量
+
+| **变量名称** | **说明** |
+| ------------------ | ---------------------- | 
+| `${timestamp}` | 数据采集时的 UNIX 时间戳。 |
+| `${node}` | 南向采集点位所属的南向驱动名称。<br> 示例：`modbus` |
+| `${group}` | 南向采集点位所属的南向驱动的采集组的名称。<br> 示例：`group` |
+| `${tags}` | 南向采集点位有效值的数组集合。<br> 示例：`[{"name": "tag1", "value": 123}, {"name": "tag2", "value": 456}]` |
+| `${tag_values}` | 南向采集点位有效值的Json集合。<br> 示例：`{"tag1": 123, "tag2": 456}` |
+| `${tag_errors}` | 南向采集点位报错值的数组集合。<br> 示例：`[{"name": "tag3", "error": 2014}, {"name": "tag4", "error": 2015}]` |
+| `${tag_error_values}` | 南向采集点位报错值的Json集合。<br> 示例：`{"tag3": 2014, "tag4": 2015}` |
+| `${static_tags}` | 订阅采集组时，自定义配置的静态点位的数组集合。<br> 示例： `[{"name": "static_tag1", "value": "abc"}, {"name": "static_tag2", "value": "def"}]` <br> 详见 [静态点位](#静态点位)|
+| `${static_tag_values}` | 订阅采集组时，自定义配置的静态点位的Json集合。<br> 示例： `{"static_tag1": "abc", "static_tag2": "def"}`<br> 详见 [静态点位](#静态点位) |
+
+::: tip 注意
+`${tags}` 和 `${tag_values}` 是采集数据点的2种不同格式，`${tags}` 是数组格式，`${tag_values}` 是Json格式。一般在构建自定义数据上报格式时，使用 `${tags}` 或 `${tag_values}` 中的一种即可。
+
+`${static_tags}` 和 `${static_tag_values}`、`${tag_errors}`和`${tag_error_values}` 同理，使用其中一种即可。
+
+ MQTT 插件配置项 **上报点位错误码** 为 **False** 时，即使配置了`${tag_errors}` 和或 `${tag_error_values}`，也不上报点位错误码信息。
+
+:::
+
+
+
+上表中示例部分，原始南向驱动`modbus1`采集组`group1`下，包含4个点位，其中`tag1`和`tag2`的点位采集数据正常，`tag3`和`tag4`的点位采集数据异常。在北向节点订阅时，自定义配置的静态点位为`static_tag1`和`static_tag2`，其值分别为`abc`和`def`。
+
+以上配置，以 Values-format 数据格式上报时，内容如下：
+
+
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus1",
+    "group": "group1",
+    "values": {"tag1": 123, "tag2": 456, "static_tag1": "abc", "static_tag2": "def"},
+    "errors": {"tag3": 2014, "tag4": 2015},
+    "metas":{}
+}
+```
+
+以下示例通过设定不同的 Custom 配置，将上面 Json 报文输出为不同的数据上报格式。
+#### 示例一
+
+将数据点位转换为数组格式，并自定义Json 键名。
+
+```json
+{
+    "timestamp": "${timestamp}",
+    "node": "${node}",
+    "group": "${group}",
+    "custom_tag_name": "${tags}",
+    "custom_tag_errors": "${tag_errors}",
+}
+```
+
+实际输出结果如下：
+
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus1",
+    "group": "group1",
+    "custom_tag_name": [{"name": "tag1", "value": 123}, {"name": "tag2", "value": 456}],
+    "custom_tag_errors": [{"name": "tag3", "error": 2014}, {"name": "tag4", "error": 2015}]
+}
+```
+
+#### 示例二
+
+通过自定义数据格式，添加全局静态点位。该静态点位在所有驱动采集组上报数据时，均会携带。如 NeuronEX 部署在一个物理网关上，可将网关的SN号、IP地址、位置信息等信息，添加到所有驱动采集组中。
+
+```json
+{
+    "timestamp": "${timestamp}",
+    "node": "${node}",
+    "group": "${group}",
+    "values": "${tag_values}",
+    "gateway_info": {
+      "ip": "192.168.1.100",
+      "sn": "SN123456789",
+      "location": "shanghai"
+    }
+}
+```
+实际输出结果如下：
+
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus1",
+    "group": "group1",
+    "values": {"tag1": 123, "tag2": 456},
+    "gateway_info": {
+      "ip": "192.168.1.100",
+      "sn": "SN123456789",
+      "location": "shanghai"
+    }
+}
+```
+
+#### 示例三
+
+将采集数据点位、静态点位、驱动、采集组信息放入 Json 子节点中，可自定义 Json 节点名称。目前自定义数据结构做多支持三层子层级。
+
+```json
+{
+    "timestamp": "${timestamp}",
+    "data": {
+      "child_node": {
+        "node": "${node}",
+        "group": "${group}",
+        "tag_values": "${tag_values}",
+        "static_tag_values": "${static_tag_values}",
+        "tag_error_values": "${tag_error_values}"
+      }
+    }
+}
+```
+
+数据上报的格式为：
+```json
+{
+    "timestamp": 1650006388943,
+    "data": {
+      "child_node": {
+        "node": "modbus",
+        "group": "group",
+        "tag_values": {"tag1": 123, "tag2": 456},
+        "static_tag_values": {"static_tag1": "abc", "static_tag2": "def"},
+        "tag_error_values": {"tag3": 2014, "tag4": 2015}
+      }
+    }
+}
+```
+
+
+## 静态点位
+
+静态点位功能，支持在南向驱动数据上报时，由用户在**北向应用组列表**页面手动配置静态点位，在数据上报时，将静态点位数据一并上报。
+
+![static-tags](./assets/static-tags.png)
+
+静态点位配置，需输入标准JSON格式内容，每个静态点位均为JSON对象中的键值对。静态点位将根据配置的数据上报格式（Values-format、Tags-format、ECP-format）与采集组数据一并上报。
+
+```json
+  {
+      "location": "sh",
+      "sn_number": "123456"
+  }
+
+```
+
+每个南向采集组，可分别配置不同静态点位。表示该采集组代表的物理设备，具有哪些静态属性信息。
+
+静态点位功能支持布尔、整型、浮点型、字符串四种数据类型。复杂数据类型，如数组、结构体等，将以字符串形式上报。
+
+如果添加的静态点位，为 NeuronEX 实例中所有采集组共用，既可以勾选**所有采集组**，添加静态点位，也可以在 Custom 自定义格式中，统一添加静态点位，参考 [自定义格式：示例二](#自定义格式)。
+
+::: tip 注意
+静态点位命名，不能和南向驱动采集的点位名称相同。
+
+如命名相同，则如果选择`Values-format`上报数据时，静态点位数据将覆盖南向驱动采集的点位数据.
+
+如果选择`Tags-format`、`ECP-format`或`Custom`上报数据时，静态点位数据将和南向驱动采集的点位数据一起重复上报。
+:::
+
+## 读 Tags
+
+### 请求
+
+通过发送 JSON 形式的请求到 MQTT 主题 **/neuron/{node_name}/read/req**，您可以读取一组点位数据。
+
+#### 请求体
+
+读请求体由以下字段构成：
+* `uuid` : 唯一的标志，会在响应中原样返回用以区分对应的请求。
+* `node` : 某个南向节点名字。
+* `group` : 南向节点的某个组的名字。
+
+以下为一个读请求样例：
+
+```json
+{
+    "uuid": "bca54fe7-a2b1-43e2-a4b4-1da715d28eab",
+    "node": "modbus",
+    "group": "grp"
+}
+```
+
+### 响应
+
+读响应会发布到 MQTT 主题 **/neuron/{node_name}/read/resp** 。
+
+#### 响应体
+
+读响应体由以下字段构成：
+* `uuid` : 对应请求中所设置的唯一标志。
+* `tags` : 点位数据数组，和 [tags 格式](#tags-格式)中的表示方法一样。
+
+以下为一个读响应样例：
+
+```json

+# Upstream/Downstream Data Format
+
+The following contents describe how MQTT plugin publishes collected data, and how to read or write data through MQTT plugin.
+
+## Data Upload
+
+The MQTT plugin publishes collected data in JSON format to some user-defined topics. The exact format of the data reported is controlled by the **Upload Format** parameter. There are four formats, [**Values-format**](#values-format), [**Tags-format**](#tags-format),  [**ECP-format**](#ecp-format), and [**Custom**](#custom-format).
+
+### Upload Topic
+
+The upload topic is specified by the **upload-topic** parameter, and the default one set through the dashboard is **/neuron/{MQTT driver name}**.
+
+### Values Format
+
+In **Values-format**, the upload data has the following fields:
+* `timestamp`: the Unix timestamp when the data was collected
+* `node`: name of the south node from which data was collected
+* `group`: name of the south node group that the tags belong to
+* `values`: dictionary storing tags with successfully collected values
+* `errors`: dictionary storing tags with encountered error codes
+* `metas`: driver related metadata information
+
+The following example is in **Values-format**, where tag values collected successfully are stored in a dictionary, while error codes in another.
+
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus",
+    "group": "grp",
+    "values":
+    {
+        "tag0": 123
+    },
+    "errors":
+    {
+        "tag1": 2014
+    },
+    "metas":{}
+}
+```
+
+::: tip
+When a tag is collected successfully, the collected data is returned. When a tag collection fails, the error code is returned instead of the value.
+
+When the **Upload Tag Error Code** parameter is set to **False**, the error code is not reported.
+:::
+
+### Tags Format
+
+In **Tags-format**, the upload data has the following fields:
+* `timestamp`: the Unix timestamp when the data was collected
+* `node`: name of the south node from which data was collected
+* `group`: name of the south node group that the tags belong to
+* `tags`: tags data array where each element corresponds to one tag in the group
+* `name`: the name of the tag
+* `value`: the value of the tag
+* `error`: the error code of the tag
+
+The following example is in **Tags-format**, where tag data are stored in an array. Each element has the name of the tag, and the tag value or error code if something went wrong.
+
+```json
+{
+  "timestamp": 1647497389075,
+  "node": "modbus",
+  "group": "grp",
+  "tags": [
+    {
+      "name": "tag0",
+      "value": 123,
+    },
+    {
+      "name": "tag1",
+      "error": 2014
+    }
+  ]
+}
+```
+
+::: tip
+Tag value is returned only when the tag is read successfully. If something goes wrong when reading a tag, the error code is returned.
+
+When the **Upload Tag Error Code** parameter is set to **False**, the error code is not reported.
+:::
+
+### ECP Format
+
+In **ECP-format**, the upload data has the following fields:
+* `timestamp`: the Unix timestamp when the data was collected
+* `node`: name of the south node from which data was collected
+* `group`: name of the south node group that the tags belong to
+* `tags`: tags data array where each element corresponds to one tag in the group
+* `name`: the name of the tag
+* `value`: the value of the tag
+* `type`: the type of the tag, which can be Boolean, Integer, Float, or String
+
+The following example data is in **ECP-format**, where tag data are stored in an array. Each element has the name of the tag, the tag type and the tag value, excluding tags where collection failed.
+
+Data classes are divided into four types: Boolean, Integer, Float, and String.
+* type = 1 Boolean
+* type = 2 Integer
+* type = 3 Float
+* type = 4 String
+
+```json
+{
+  "timestamp": 1647497389075,
+  "node": "modbus",
+  "group": "grp",
+  "tags": [
+    {
+      "name": "tag_boolean",
+      "value": true,
+      "type": 1,
+    },
+    {
+      "name": "tag_int32_",
+      "value": 123,
+      "type": 2,
+    },
+    {
+      "name": "tag_float",
+      "value": 1.23,
+      "type": 3,
+    },
+    {
+      "name": "tag_string",
+      "value": "abcd",
+      "type": 4,
+    }
+  ]
+}
+```
+
+::: tip
+ECP-format does not support reporting tag error codes.
+
+Regardless of whether the **Upload Tag Error Code** parameter is set to **False** or **True**, tag error codes are not reported.
+:::
+
+### Custom Format
+
+In the custom format, use built-in variables to define the data upload format.
+
+![custom-format](./assets/custom-format-en.png)
+
+#### Variables
+
+| *variable* | *description* |
+| ------------------ | ---------------------- | 
+| `${timestamp}` | The UNIX timestamp when the data was read. |
+| `${node}` | The name of the southbound node. <br> Example: `modbus` |
+| `${group}` | The name of the group. <br> Example: `group` |
+| `${tags}` | The array of valid tag values. <br> Example: `[{"name": "tag1", "value": 123}, {"name": "tag2", "value": 456}]` |
+| `${tag_values}` | The array of valid tag values, Value Format <br> Example: `{"tag1": 123, "tag2": 456}` |
+| `${tag_errors}` | The array of error codes. <br> Example: `[{"name": "tag3", "error": 2014}, {"name": "tag4", "error": 2015}]` |
+| `${tag_error_values}` | The array of error codes, Value Format <br> Example: `{"tag3": 2014, "tag4": 2015}`   |
+| `${static_tags}` | The array of static tags. <br> Example: `[{"name": "static_tag1", "value": "abc"}, {"name": "static_tag2", "value": "def"}]` <br> See [Static Tags](#static-tags) |
+| `${static_tag_values}` | The array of static tags, Value Format <br> Example: `{"static_tag1": "abc", "static_tag2": "def"}` <br> See [Static Tags](#static-tags) |
+
+::: tip
+`${tags}` and `${tag_values}` are two different formats for tag values. `${tags}` is an Array format, and `${tag_values}` is a JSON format. In most cases, use one of them.
+
+`${static_tags}` and `${static_tag_values}`, `${tag_errors}` and `${tag_error_values}` are similar. Use one of them.
+
+When the **Upload Tag Error Code** parameter is set to **False**, even if `${tag_errors}` and `${tag_error_values}` are configured, tag error codes are not reported.
+:::
+
+The example above is based on the original southbound driver `modbus1` and group `group1`, which contains 4 tags. `tag1` and `tag2` are collected successfully, while `tag3` and `tag4` are collected with errors. When subscribing to the northbound node, the static tags are configured as `static_tag1` and `static_tag2`, with values of `abc` and `def` respectively.
+
+The above configuration, when reported in **Values-format** data format, is as follows:
+
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus1",
+    "group": "group1",
+    "values": {"tag1": 123, "tag2": 456, "static_tag1": "abc", "static_tag2": "def"},
+    "errors": {"tag3": 2014, "tag4": 2015},
+    "metas":{}
+}
+```
+
+The following example shows how to output the above JSON message in different data reporting formats by setting different **Custom** configurations.
+
+
+#### Example One
+
+Convert tag data to array format and customize the Json key name.
+
+```json
+{
+    "timestamp": "${timestamp}",
+    "node": "${node}",
+    "group": "${group}",
+    "custom_tag_name": "${tags}",
+    "custom_tag_errors": "${tag_errors}",
+}
+```
+
+The actual output result is as follows:
+
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus1",
+    "group": "group1",
+    "custom_tag_name": [{"name": "tag1", "value": 123}, {"name": "tag2", "value": 456}],
+    "custom_tag_errors": [{"name": "tag3", "error": 2014}, {"name": "tag4", "error": 2015}]
+}
+```
+
+#### Example Two
+
+Add global static tags through custom data format. These static tags will be carried in all driver group data reporting. For example, if NeuronEX is deployed on a gateway hardware, you can add the gateway's SN number, IP address, and location information to all driver groups.
+
+```json
+{
+    "timestamp": "${timestamp}",
+    "node": "${node}",
+    "group": "${group}",
+    "values": "${tag_values}",
+    "gateway_info": {
+      "ip": "192.168.1.100",
+      "sn": "SN123456789",
+      "location": "shanghai"
+    }
+}
+```
+The actual output result is as follows:
+
+```json
+{
+    "timestamp": 1650006388943,
+    "node": "modbus1",
+    "group": "group1",
+    "values": {"tag1": 123, "tag2": 456},
+    "gateway_info": {
+      "ip": "192.168.1.100",
+      "sn": "SN123456789",
+      "location": "shanghai"
+    }
+}
+```
+
+#### Example Three
+
+Put tag data, static tags, driver, and group information into a Json sub-node, and customize the Json node name. Currently, the custom data structure supports up to three sub-levels.
+
+```json
+{
+    "timestamp": "${timestamp}",
+    "data": {
+      "child_node": {
+        "node": "${node}",
+        "group": "${group}",
+        "tag_values": "${tag_values}",
+        "static_tag_values": "${static_tag_values}",
+        "tag_error_values": "${tag_error_values}"
+      }
+    }
+}
+```
+
+The data reporting format is as follows:
+```json
+{
+    "timestamp": 1650006388943,
+    "data": {
+      "child_node": {
+        "node": "modbus",
+        "group": "group",
+        "tag_values": {"tag1": 123, "tag2": 456},
+        "static_tag_values": {"static_tag1": "abc", "static_tag2": "def"},
+        "tag_error_values": {"tag3": 2014, "tag4": 2015}
+      }
+    }
+}
+```
+
+
+## Static Tags
+
+The static tag feature supports configuring static tags manually in the **North Application Group List** page, and reporting static tag data together with the collected data.
+
+![static-tags](./assets/static-tags-en.png)
+
+Static tag configuration requires inputting standard JSON format content, where each static tag is a key-value pair in the JSON object. Static tags will be reported together with the collected data according to the configured data reporting format (Values-format, Tags-format, ECP-format).
+
+```json
+  {
+      "location": "sh",
+      "sn_number": "123456"
+  }
+
+```
+
+Each southbound collection group can configure different static tags. This represents the physical device represented by the collection group, with which static attribute information.
+
+Static tag feature supports **Boolean**, **Integer**, **Float**, and **String** data types. Complex data types, such as arrays and structures, will be reported as **String**.
+
+If the static tags added are shared by all collection groups in the NeuronEX instance, you can select **All Collection Groups** to add static tags, or add static tags in the **Custom** custom format, as shown in [Custom Format: Example Two](#example-two).
+
+::: tip
+Static tag names must not be the same as the tag names collected by the southbound driver.
+
+If the names are the same:
+- When using `Values-format` for data upload, the static tag data will overwrite the tag data collected by the southbound driver.
+- When using `Tags-format`, `ECP-format`, or `Custom` for data upload, both the static tag data and the southbound driver collected tag data will be reported together (resulting in duplicate reporting).
+
+:::
+
+
+
+## Read Tag
+
+### Request
+
+You can read a group of tags by sending requests in JSON to the MQTT topic **/neuron/{node_name}/read/req**.
+
+#### Body
+
+The read request body should have the following fields:
+* `uuid`: a unique identifier, which will be echoed back in the response to help identify the corresponding request
+* `node`: the name of a southbound node
+* `group`: the name of a group to read
+
+Below is an example read request:
+
+```json
+{
+    "uuid": "bca54fe7-a2b1-43e2-a4b4-1da715d28eab",
+    "node": "modbus",
+    "group": "grp"
+}
+```
+
+### Response
+
+Read response will be published to the MQTT topic **/neuron/{node_name}/read/resp**.
+
+#### Body
+
+The read response body has the following fields:
+* `uuid`: the same unique identifier which is set by the corresponding request
+* `tags`: tags data array, same as that in [tags format](#tags-format)
+
+Below is an example read response:
+
+```json
+{
+  "uuid": "bca54fe7-a2b1-43e2-a4b4-1da715d28eab",
+  "tags": [
+    {
+      "name": "tag0",
+      "value": 4,
+    },
+    {
+      "name": "tag1",
+      "error": 2014
+    }
+  ]
+}
+```
+
+::: tip
+Tag value is returned only when the tag is read successfully. If something goes wrong when reading a tag, the error code is returned.
+:::
+
+## Write Tag
+
+### Request
+
+You could write a tag by sending requests in JSON to the MQTT topic designated by the **Write Request Topic** parameter.
+
+::: tip
+Before Neuron version 2.4.5, the write request topic was hard-coded to **/neuron/{random_str}/write/req**.
+:::
+
+#### Body
+
+#### Write one tag
+
+The write request body should have the following fields:
+* `uuid`: a unique identifier, which will be echoed back in the response to help identify the corresponding request
+* `node`: the name of a southbound node
+* `group`: the name of a group
+* `tag`: the name of a tag
+* `value`: the value to write
+
+Below is an example of write request:
+
+```json
+{
+    "uuid": "cd32be1b-c8b1-3257-94af-77f847b1ed3e",
+    "node": "modbus",
+    "group": "grp",
+    "tag": "tag0",
+    "value": 1234
+}
+```
+
+#### Write multiple tags
+
+Since Neuron version 2.6.0, write requests also support writing multiple tags at
+a time. To write multiple tags at a time, the request body should have the
+following fields:
+* `uuid` : a unique identifier, which will be echoed back in the response to help identify the corresponding request.
+* `node` : the name of a southbound node.
+* `group` : the name of a group.
+* `tags` : tags data array where each element corresponds to one tag in the group.
+
+Below is an example write request:
+
+```json
+{
+    "uuid": "cd32be1b-c8b1-3257-94af-77f847b1ed3e",
+    "node": "modbus",
+    "group": "grp",
+    "tags": [
+      {
+        "tag": "tag0",
+        "value": 1234
+      },
+      {
+        "tag": "tag1",
+        "value": 5678
+      }
+    ]
+}
+```
+
+
+### Response
+
+Write response will be published to the MQTT topic designated by the **Write Response Topic** parameter.
+
+::: tip
+Before Neuron version 2.4.5, the write response topic was hard-coded to **/neuron/{random_str}//write/resp**.
+:::
+
+#### Body
+
+The write response body has the following fields:
+* `uuid`: the same unique identifier which is set by the corresponding request.
+* `error`: error code if something bad happens, `0` represents success.
+
+Below is an example of write response:
+
+```json
+{
+  "uuid": "cd32be1b-c8b1-3257-94af-77f847b1ed3e",
+  "error": 0
+}
+```
+
+## Driver Status Report
+
+Reports status of all the southbound nodes to the specified topic.
+
+### Status Report Topic
+
+The status report topic is specified in the northbound node configuration. Its default value is **/neuron/{random_str}/state/update**.
+
+### Status Report Interval
+
+The status report interval is specified in the northbound node configuration, indicating the number of seconds between each message. The default value is 1, with an allowed range of 1-3600.
+
+### Reporting Message Format
+
+The reported data consists of the following fields:
+* `timestamp`: The UNIX timestamp when the data was collected.
+* `states`: An array of node status information.

+**Address**: `1!40001` (Slave ID 1, holding register 40001)
+**Attribute**: `Read` and `Write`
+**Data Type**: `INT16`
+
+### View Tag Values
+
+After configuring the tags, go to the **Data Monitoring** page, select the device and group you just created, and you will see the values of the tags.
+
+![data-monitor](./assets/data-monitoring.png)
+
+## Create a Northbound Application
+
+Use MQTT to send the data collected from the Modbus device to an MQTT Broker.
+
+**Northbound Application Management** -> **Add Application**. In the pop-up dialog box, fill in the application information to create the application.
+Select `MQTT` for the **Plugin** and enter `mqtt` for the **Name**.
+
+### Configure the Northbound Application
+
+After creating the northbound application, go to the northbound configuration page. The default server address is `broker.emqx.io` and the port is `1883`. If you need to connect to another MQTT Broker, please modify it according to the actual situation.
+
+### Subscribe to Southbound Data Groups
+
+On the **Northbound Application Management** page, click the northbound application to enter the **Subscription Management** page. Click **Add Subscription**, and in the pop-up dialog box, select the Modbus device and group you just created.
+
+![subscribe](./assets/subscription-add.png)
+
+Remember the topic used for the subscription, as you will need to subscribe to this topic later to see the data. The default topic format is `/neuron/{application_name}`.
+
+At this point, the configuration for Neuron to collect data via Modbus TCP and send it via MQTT is complete.
+
+## Use MQTTX to Subscribe to the Topic and View Data
+
+After subscribing, open [MQTTX](https://mqttx.app/zh), create a new connection, and connect to `broker.emqx.io:1883` (modify according to the MQTT broker configured in the northbound application).
+
+After a successful connection, subscribe to the topic `/neuron/mqtt` (modify according to the topic used in the northbound subscription), and you will see the tag data.

-Functional testing uses the robotframework automated testing framework, providing templates for each test case of the northbound APP and southbound DRIVER types.
-
-Testing is divided into the following categories.
-|Test case|Description|
-|-----|----------|
-|Core interface test|Mainly including the addition, deletion, modification, query, subscription, and other operations of the HTTP API interface for core data(PLUGIN, NODE, GROUP, TAG)|
-|Southbound DRIVER test||
-|Northbound APP test||
-|Plugin specific test case|Such as OPC UA specific device discovery, can different devices be connected normally|
-
-To run all functional testers
