•指向第一条记录第一项的日志指针：这是指向数据日志中第一条记录的指针•指向最后一条记录的日志指针；i、 e.：正在运行或已停止•使用的日志记录：这是已写入数据日志日志的记录数，直到下一次读取的剩余时间：这是一个计数器，显示直到下一条记录写入数据日志的剩余时间。数据记录器有两种操作模式，运行填充和循环。在“运行到填充”模式下，如果内存不足，无法添加另一条记录，数据日志将停止向内存结构中写入记录。根据每个记录的大小，数据日志可能不一定使用全部65536字节的可用存储空间。在循环模式下，数据日志将继续将新记录写入日志，超出最后可用的记录空间
• Log Pointer to First Item of First Record: This is a pointer to the first record in the Data Log • Log Pointer to First Item of Record After Last: This is a pointer to the next record to be written into the Data Log • Log Status: This reports the current status of the Data Log; i.e.: Running or Stopped • Log Records Used: This is the number of records that have been written into the Data Log Log Time Remaining Until Next Reading: This is a counter showing how much time remains until the next record is to be written into the Data Log The Data Logger has 2 modes of operation, Run to Fill and Circulate. In the Run to Fill mode, the Data Log will stop writing records into the memory structure when there is not enough memory to add another record. Depending on the size of each record, the Data Log may not necessarily use the entire 65536 bytes of storage available. In the Circulate mode, the Data Log will continue to write new Records into the Log beyond the last available Record space
