3重置计数R/NV
返回任何原因的固件重置的生存期计数。仪表将此计数保持在个单位
非易失性存储器的受保护部分，不受配置重置的影响（见AV190）。
每次复位时，仪表恢复累积能量、需求统计和脉冲输入计数
来自非易失性存储器。然而，所有模拟统计数据复位，加上启动时间（见AV104），
能量时间戳（见AV174）和二进制输入（见BI201、BI202）。
AV104启动时间R
返回自上次仪表重置以来的时间，以秒为单位。要确定原因，请读取上次重新启动
设备对象的原因属性。
AV123 MAC地址R/W/NV
设置MS/TP地址0–254（MS/TP保留用于广播的地址255）。
当自动地址激活时（请参阅BV113），返回自动选择的地址（请参阅配置）。
否则，返回用户配置的地址。
设置任何地址也会将自动地址设置为非活动。设置新地址时，仪表
使用原始地址进行确认。因此，客户机必须暂时记住
原始地址，仅在下个新事务开始时切换。
当大信息帧（请参阅设备）不等于0且MAC地址小于或等于
大主控（见设备），仪表在MS/TP主控模式下运行。否则
在MS/TP从属模式下运行（无令牌传递或轮询，无I-Am或I-Have服务启动）。
注意：由于大主地址必须为127或更少，因此地址128–254始终是MS/TP从地址。

3 Reset Count R/NV Returns a lifetime count of firmware resets for any reason. The meter maintains this count in a protected section of non-volatile memory unaffected by Configuration Reset (see AV190). At each reset, the meter restores accumulated energy, demand statistics, and pulse input counts from non-volatile memory. However, all the analog statistics reset, plus the Up Time (see AV104), Energy Timestamp (see AV174), and Binary Inputs (see BI201, BI202). AV104 Up Time R Returns the time since the last meter reset, in seconds. To determine the cause, read the Last Restart Reason property of the Device object. AV123 MAC Address R/W/NV Sets the MS/TP address, 0 – 254 (MS/TP reserves address 255 for broadcast). When Auto Address is Active (see BV113), returns the auto-selected address (see Configuration). Otherwise, returns the user-configured address. Setting any address also sets Auto Address to Inactive. When setting a new address, the meter acknowledges using the original address. Therefore, a client must temporarily remember the original address and only switch at the beginning of the next new transaction. When Max Info Frames (see Device) is not equal to 0 and the MAC Address is smaller than or equal to the Max Master (see Device), the meter operates in MS/TP master mode. Otherwise, the meter operates in MS/TP slave mode (no token passing or polling, no initiation of I-Am or I-Have services). NOTE: Because Max Master must be 127 or less, addresses 128 – 254 are always MS/TP slaves. Default: Varies EM-RS485 BACnet Protocol Guide Page 29 of 49 154-0022-0C AV124 RS485 Baud Rate R/W/NV Sets the communication baud rate, 1200 – 460800. When Auto Baud Rate is Active (see BV114), returns the auto-detected baud rate (see Configuration). Otherwise, returns the user-configured baud rate. Almost by definition, successfully reading baud rate implies a correct value, with no further action required. However, when transitioning an MS/TP network to a new baud rate, it may be useful to remotely configure the new baud rate before transitioning the gateway/controller. Setting any user-configured baud rate also sets Auto Baud Rate to Inactive. WARNING: The meter provides no facility to revert the baud rate remotely. Once written, the meter will lose communication until the client baud rate matches the new configuration. Default: Varies AV134 Smoothed Temperature Response Time R/W/NV Sets the step response time for smoothed temperature (see AI312), in seconds. Across all groups, the various Smoothed values track the instantaneous measurement after the application of a first-order exponential function. This low pass filter attenuates fast changes, such as the inrush current of a large industrial motor. Smoothed values may provide a stable baseline measurement but will always lag the instantaneous measurement (see Figure 16A). Formally, response time sets the time required for a Smoothed value to complete 90% of the transition after an ideal step between two stable values (see Figure 16B). 90% τ A: General Smoothing B: Ideal Step Response instantaneous smoothed Figure 16: Smoothed Response Time During periods of invalid measurement, Smoothed values return 0 (undefined). The resumption of valid measurements momentarily suppresses the smoothing function while the value stabilizes. Default: 30 seconds AV142 Smoothed Frequency Response Time R/W/NV Sets the step response time (see AV134) for smoothed Frequency (see AI412) and Voltage Angle (e.g. AI1442), in seconds. Default: 60 seconds AV144 Smoothed Voltage Response Time R/W/NV Sets the step response time (see AV134) for smoothed RMS Voltage (e.g. AI1422), in seconds. Default: 10 seconds EM-RS485 BACnet Protocol Guide Page 30 of 49 154-0022-0C AV154 Smoothed Current Response Time R/W/NV Sets the step response time (see AV134) for smoothed RMS Current (e.g. AI1522), Current Angle (e.g. AI1542), and Power Factor (e.g. AI1552), in seconds. Default: 2 seconds AV164 Smoothed Power Response Time R/W/NV Sets the step response time (see AV134) for smoothed Power (e.g. AI1602), in seconds. Default: 2 seconds AV174 Energy Timestamp R Returns a high resolution timestamp, 0 – 4194304 milliseconds (222 – 1, about 1 hour). The timestamp value updates atomically with the various energy accumulators. If read atomically with one or more energy measurements by a Read-Multiple query, this timestamp may be useful for calculating accurate average power from differential energy: 𝑃𝐴𝑉𝐺 = ∆𝐸 ∆𝑡 = 𝐸2 − 𝐸1 𝑡2 − 𝑡1 AV182 Demand Synchronization Hour R/W/NV Sets the hour of the day for demand window synchronization, 0 – 23 hours. Only applies when the Demand Window Synchronization mode is Every Day (see MSV181). In this case, synchronization occurs at the top of the selected hour. Default: 0 (midnight) AV183 Demand Window Time R/W/NV Sets the maximum demand window time, 0 – 1440 minutes. The demand measurements (see AI1800) measure average power within a windowed period. Every time the Elapsed Demand Window time (see AV184) reaches this limit, the current window closes and a new window starts. If set to 0 minutes, the window time is unlimited. In this case, new windows are only started by external synchronization (see MSV181) or software synchronization (see AV184). Default: 15 minutes AV184 Elapsed Demand Window R/W0 Returns the time since the beginning of the current demand window, in minutes. The demand measurements (see AI1800) measure average power within a windowed period. This value resets to 0 at the beginning of each new demand window. Writing 0 at any time automatically starts a new window (software synchronization). EM-RS485 BACnet Protocol Guide Page 31 of 49 154-0022-0C AV186 Demand Window Count R/NV Returns the number of completed demand windows. Any demand window at least 1 second long counts, regardless of whether the window was defined by external synchronization (see MSV181), software synchronization (see AV184), or elapsed time (see AV183). Resetting all or a portion of the demand statistics (see AV192, AV1192) does not automatically start a new demand window. The system and all phase demand values update together (e.g. AI1800), so this count can serve as a unique key to identify each new batch of demand statistics (e.g. for logging). Resets to 0 only when the system and all phase demand statistics are reset together (see AV192). AV190 Configuration Reset W Always returns 0. Write the reset key to reset the meter to factory defaults. WARNING: The entire non-volatile configuration will be permanently lost; previous configurations cannot be recovered. This includes accumulated energy, demand statistics, and pulse input counts. This also includes the current RS485 serial format, MAC Address, and Device ID. The only parameters not affected are the Reset Count (see AV103) and the Energy Reset Count (see AV194). After a configuration reset, the meter itself will reset and re-learn the current baud rate, serial format, protocol, and MAC Address (see Configuration). If the Device ID was previously changed, it may be necessary for the controller to rediscover the meter. • Write 9699690 to reset the meter to factory defaults. AV192 Statistics Reset W Always returns 0. Write one of the following keys to reset some or all of the phase statistics. Writing any other value results in an error response. WARNING: Selected statistics will be permanently lost; previous records cannot be recovered. System statistics ONLY: • Write 4765089 to reset analog statistics (AI410 – AI678: Minimum, Maximum, Average) • Write 5338209 to reset demand statistics (AI8
