6.3.9 MPL: MaximumPowerLimit（最大功率限制）
The maximum power limit field is a 1 6-bit field that indicates the maximum power that the load may draw, in watts. Calculation of this field is identical to that of the TransferAmount field (see 6.3.6). See also note in 8.6 for functional requirements of the MeterApplication Process.
最大功率限制字段是一个16位字段，表示负载可能消耗的最大功率，单位为瓦。该字段的计算与TransferAmount字段的计算相同（参见6.3.6）。参见8.6中关于MeterApplication Process功能需求的注释。
6.3.10 MPPUL: MaximumPhasePowerUnbalanceLimit （最大相位功率不平衡限制）
The maximum phase power unbalance limit field is a 1 6-bit field that indicates the maximum allowable power difference between phase loads, in watts. Calculation of this field is identical to that of the TransferAmount field (see 6.3.6).
最大相位功率不平衡限制字段是一个16位字段，表示相位负载之间的最大允许功率差，单位为瓦。该字段的计算与TransferAmount字段的计算相同（参见6.3.6）。
6.3.11 Rate: TariffRate
Reserved for future definition by the STS Association.
由STS协会将来定义保留。
6.3.12 WMFactor: WaterMeterFactor
Reserved by the STS Association for water application.
由STS协会保留，用于供水用途。
6.3.13 Register: RegisterToClear
A unique 1 6-bit binary value in the range 0 to FFFF hex; to select the particular register that should be cleared with the ClearCredit token. The defined values are given in Table 28.
一个唯一的16位二进制值，范围为0到FFFF十六进制；以选择应该使用ClearCredit令牌清除的特定寄存器。表28给出了定义的值。
6.3.14 NKHO: NewKeyHighOrder
The high order 32 bits of the new DecoderKey that has been generated (see 6.4.4) and which is to be transferred to the payment meter by means of the token.
已生成的新DecoderKey的高阶32位（见6.4.4），并将通过令牌传输到付费仪表。
6.3.15 NKLO: NewKeyLowOrder
The low order 32 bits of the new DecoderKey that has been generated (see 6.4.4) and which is to be transferred to the payment meter by means of the token.
已生成的新DecoderKey的低阶32位（见6.4.4），并将通过令牌传输到付费仪表。
6.3.16 NKMO1 : NewKeyMiddleOrder1
The second most significant 32 bits of the 1 28-bit DecoderKey that has been generated (see 6.4.4) and which is to be transferred to the payment meter by means of a token.
已生成的1个28位DecoderKey（见6.4.4）中第二个最重要的32位，它将通过令牌传输到付费仪表。
6.3.17 NKMO2: NewKeyMiddleOrder2
The third most significant 32 bits of the 1 28-bit DecoderKey that has been generated (see 6.4.4) and which is to be transferred to the payment meter by means of a token.
已生成的1个28位DecoderKey（见6.4.4）中第三个最重要的32位，它将通过令牌传输到付费仪表。
6.3.18 KENHO: KeyExpiryNumberHighOrder
This is the high order 4 bits of the KEN (see 6.1 .10).
这是KEN的高阶4位（见6.1 .10）。
6.3.19 KENLO: KeyExpiryNumberLowOrder
This is the low order 4 bits of the KEN (see 6.1 .10).
这是KEN的低阶4位（见6.1 .10）。
6.3.20 RO: RolloverKeyChange
The RO bit shall be set to 1 in the Set1stSectionDecoderKey token when the BaseDate associated with the destination VendingKey/DecoderKey is later than the BaseDate associated with the source VendingKey/DecoderKey and shall be set to 0 otherwise.
当目的VendingKey/DecoderKey关联的BaseDate比源VendingKey/DecoderKey关联的BaseDate晚时，Set1stSectionDecoderKey token中的RO位设置为1，否则设置为0。
If the RolloverKeyChange bit is set = 1 , the payment meter shall perform a roll over key change. This operation is identical to a normal key change, except that the TID memory store in the payment meter is filled with token identifiers of value 0 (zero).
如果RolloverKeyChange位设置为= 1，则付费仪表将执行滚转密钥更改。此操作与普通的键更改相同，只是付费计量表中的TID内存存储中填充了值为0（零）的令牌标识符。
6.3.21 S&E: SignAndExponent
The bit positions for extraction of S&E variables s, e 4 , e 3 and e 2 are given in Table 29. For the assignment of values to s and e, see 6.3.6.3.
提取S&E变量s、e4、e3和e2的位位置如表29所示。关于s和e的赋值，请参见6.3.6.3。
6.3.22 CRC_C: CyclicRedundancyCheck_C
The CRC_C is a checksum field used to verify the integrity of the data transferred for token Class 0 with SubClass 4 to 7 and is calculated as defined in 6.3.7, but with the following change:
CRC_C是一个校验和字段，用于验证从子类4到7的令牌0传输的数据的完整性，其计算方法与6.3.7中定义的一样，但有以下变化：
A single byte with the value of 01 hex is appended to the 56-bit value before calculation starts. An example of a CRC_C calculation is given in Table 30.
在开始计算之前，在56位的值后面附加一个值为01十六进制的单个字节。表30给出了一个CRC_C计算的示例。
