   * Read: Used to read data
   * Write: Used to write data
   * Subscribe: Only sends messages when data changes. For example, the default data is 0, when the data changes to 2, a message will be sent
-  * Static: Requires a value to be assigned at configuration, and the assigned value can also be seen on the monitoring page after configuration
 * **Type**: The type of data stored at this tag. This could be integer, float, string, or boolean. Choose the type according to your device data.
-* **Address**: Fill in the driver address, for example, 1!40001. 1 represents the point site number set in the Modbus simulator, and 40001 represents the point register address. For detailed instructions on how to use the driver address, please refer to [South Device - Modbus TCP](./modbus-tcp/modbus-tcp.md#examples).
-* **Decimal**: Default is not filled; when the tag attribute includes write, you can set the Decimal. In this case, device value * decimal = display value. If the point Decimal is 0.1, and the value written into the device is 234, the display value is 23.4.

 Once the tag is created and the equipment card is operational, the connection status should display as **Connected**. If the status remains as **Disconnected**, please execute the following commands in the terminal of the Neuron runtime environment. This will help verify if the Neuron runtime environment can access the appropriate IP address and port.

 ### Troubleshooting
 
-If there are any issues with device operation, you can click on the DEBUG log chart. The system will automatically print DEBUG level logs for that node and switch back to the system default log level after ten minutes. Later, you can click on **System Information** -> **Logs** at the top of the page to view logs and perform troubleshooting.
