| 模板：功能描述，使用场景 | 0xMN | 请求： Read Offset：0x0000 Length：1 响应： End of List：0 Data: 0：功能0 1：功能1 | 请求： Write Offset：0x0000 Length：1 Data： 0：功能0 1：功能1 |
| Platform Power Consumption on the DC side. | 0x00 | 1st byte: Sub command, 0x00 – Platform Power Consumption on the DC side. If the Power Source Efficiency is not supplied, NM treats this reading as a reading on the primary side (assuming Power Source Efficiency to be 100%). 2nd to 18th byte: Reserved. Write at least two bytes. Recommended to write as 00h. | 1st byte: Completion Code 2nd byte: Platform Power Consumption in [Watts]. Values below 0 are ignored and treated as a power reading failure. 3nd and 4th byte: Reading value. |
| Inlet Air Temperature. For Inlet Air Temperature | 0x10 | 1st byte: Sub command, 0x10 – Inlet Air Temperature. For Inlet Air Temperature 2nd to 18th byte: Reserved. Write at least two bytes. Recommended to write as 00h. | 1st byte: Completion Code 2nd byte: Inlet Air Temperature in degrees centigrade. Values below -128 degrees centigrade and above +127 degrees centigrade will be ignored and treated as a temperature reading failure. 3nd and 4th byte: Reading value. |
| Zone Fan Speed. | 0x30 | 1st byte: Sub command, 0x30 - Zone Fan Speed. 2nd to 18th byte: One to six groups can be queried. The format of the first group is {group id,reserverd}, and the format of the remaining groups is {Zone Fan Speed,group id,reserverd}. Zone Fan Speed is recommended to write as 30h. | 1st byte to 24th byte: Return based on the query quantity. The format of each group is {Completion Code, Zone Fan Speed, Reading Value, Reading Value}. |
