The module's characteristic values are recalculated every 300 ms. To prevent values from being lost, it is necessary to collect this data quickly enough. If this is not possible, the characteristic values on the module can be locked using data point RequestDataLock01 and then read acyclically in Function model 2 - Slow master and Function model 254 - Bus controller. However, measurements are lost.
To prevent measurements from being lost, a special function has been implemented in the module that records the minimum and maximum values of all characteristic values calculated in the module. With each edge of bit MinMayUpdate01 in register Control, a new measurement can be started whereby the minimum and maximum values are reinitialized. Simultaneously, the current data is copied to the acyclic registers.
The number of collected measurements can then be read using acyclic register MinMaxCounter. The respective values are read using the acyclic minimum and maximum registers.
模块的特征值每 300 毫秒重新计算一次。为了防止值丢失，有必要足够快地收集这些数据。如果无法做到这一点，则可以使用数据点 RequestDataLock01 锁定模块上的特征值，然后在功能 Function model 2 - Slow master 和 Function model 254 - Bus controller中非循环读取。但是，测量值终会丢失。
为了防止测量丢失，在模块中实现了一个特殊功能，该功能记录模块中计算的所有特征值的最小值和最大值。利用寄存器 Control中的 MinMayUpdate01 位的每个沿, 就可以开始新的测量，从而重新初始化最小值和最大值。同时，将当前数据复制到非循环寄存器中。
然后可以使用非循环寄存器 MinMaxCounter读取所收集的测量值的数量。使用非循环最小和最大寄存器来读取相应的值。
For Iso10816, these are the Iso10816Min01-04 and Iso10816Max01-04 registers.
对于 Iso10816，这些是 Iso10816Min01-04 和 Iso10816Max01-04 寄存器。
Information: 说明:
•If data is locked with RequestDataLock01, no further measured values are collected. This only affects Function model 2 - Slow master and Function model 254 - Bus controller since the characteristic values are not locked in the standard function model. •If a characteristic value overflow or open circuit occurs, no new values are collected. •The minimum and maximum registers are each initialized using the maximum and minimum of the respective data type. If there is no valid value on the characteristic value for the overall measurement, then the initial value is retained (e.g. on overflow, open circuit or locked data). •If the data on the module is frozen (DataLockValid01 = 1), no new values are included in the minimum formation, but the measurement cycles are still counted.
•如果数据被 RequestDataLock01 锁定，则不会再收集任何测量值。这仅影响 Function model 2 - Slow master 和 Function model 254 - Bus controller功能模式，因为在标准功能模型中特征值没有被锁定。 •如果发生特征值溢出或开路（传感器断线），则不会收集新值。 •最小和最大寄存器分别使用各自数据类型的最大值和最小值进行初始化。如果整体测量的特征值没有有效值，则保留初始值（例如，在溢出、开路或锁定数据上）。 •如果模块上的数据被冻结（ DataLockValid01 = 1 ），则最小值（ minimum ）中不会包含新值，但仍会对测量周期进行计数。 |
The registers are only updated on an edge of MinMaxUpdate01 and only valid if MinMaxCounter is not equal to 0. Register MinMaxCounter specifies the number of collected measurement cycles for the minimum and maximum.
寄存器只在 MinMaxUpdate01 的沿进行更新， 并且仅当 MinMaxCounter 等于0时才有效。 寄存器 MinMaxCounter 指示最小值（ minimum ）和最大值（ maximum ）收集的测量周期数。
