与示例中一样，计算的总空间为65152/24–1=2713.67。这相当于在块511的末尾有2713条记录和40字节的未使用存储器。结构中使用的空间总量也可以在日志总记录字段的日志标题中找到。当数据日志配置为循环操作模式时，内存结构与运行填充模式相同。要读取日志数据，必须使用每个日志标头中的日志起始地址、日志记录大小和日志总记录信息。日志2的日志起始地址可以如前一次运行到填充模式计算中所示确定。任一日志在内存结构中占用的总空间是通过将日志总记录乘以日志记录大小并将该值添加到日志起始地址来确定的。需要注意的是，日志起始地址始终引用块0的第一个寄存器或数据日志内存结构的第一个字节。一旦将数据日志数据与标头分离，则需要将数据解释为结构化格式。每个记录由用户定义的参数组成。
As in the example, the total space calculated would be 65152 / 24 – 1 = 2713.67. This equates to 2713 records with 40 bytes of unused memory at the end of Block 511. The total amount of space used in the structure can also be found in the Log Header in the Log Total Records field. When the Data Log is configured for Circulate mode of operation, the memory structure is the same as for Run to Fill mode. To read the Log data, you must use the Log Starting Address, Log Record Size, and Log Total Records information from each of the Log Headers. The Log Starting Address for Log 2 can be determined as shown in the previous calculation for Run to Fill mode. The total space occupied in the memory structure by either log is determined by multiplying the Log Total Records by the Log Record Size and adding this value to the Log Starting Address. It is important to note that the Log Starting Address is always referenced to the first Register of Block 0, or the first byte of the Data Log memory structure.Once you have separated the Data Log data from the Headers, you will then need to interpret the data into a structured format. Each Record is comprised of user-defined parameters.
