数据日志中的每个条目都称为记录。记录的大小可以根据用户希望记录的参数而变化。内存结构也可以划分为两个单独的数据日志。这两个日志的大小可以由用户定义，也可以通过EnerVista PQM设置进行优化。每个数据日志的顶部都包含所谓的标题。每个数据日志标题包含以下信息…•日志时间间隔：这是用户定义的数据日志存储条目的间隔•当前日志时间和日期：这是最近记录的时间和日期•日志开始地址：这是记录数据开始的开始地址•日志记录大小：这是数据中每个记录条目的大小基于用户定义的数据日志结构的日志•日志总记录：这是基于用户定义数据日志参数结构的可用记录总数
Each entry into the Data Log is called a Record. The Record can vary in size depending upon the parameters the user wishes to log. The memory structure can also be partitioned into 2 separate Data Logs. The 2 logs can be user defined in size, or can be optimized by EnerVista PQM Setup. The top of each Data Log contains what is called the Header. Each Data Log Header contains the following information… • Log Time Interval: This is the user defined interval at which the data log will store entries • Present Log Time and Date: This is the time and date of the most recent Record • Log Start Address: This is the start address for the beginning of the logged data • Log Record Size: This is the size of each Record entry into the Data Log based upon the user defined Data Log structure • Log Total Records: This is the total number of records available based upon the user defined Data Log parameter structure
