4.5 Data Logging meter provides data logging that records the data at a set Acuvim IIR/IIE/IIW interval.This meter has 4 MegaBytes of memory which gives it extensive data- logging capabilities. It has a real-time clock that allows logs to be time-stamped when log events are created.
Page 87
Having three sets of historical logs provides you with the option of programming each log with unique parameters. For example, you can program Historical Log 1 to record measured values parameters (for example, Frequency, Voltage, Current), Log 2 to record energy values parameters, and Log 3 to record power quality parameters.

within the specified time period. NOTES: • Data logging will stop when the allocated memory for the historical data log is full if the logging timer mode is enabled, no stored data will be erased in this mode. If the logging timer mode is disabled then when the historical data log is full, the first sector of this log will be erased and overwritten by the latest records.

1100H-11DFH (Historical Log 1) 11C0H-127FH (Historical Log 2) 1280H-133FH (Historical Log 3) Block Size: 192 registers per log (384 bytes) Data Log Setting’s address map : 1100H - 1101H 1102H – 1176H 1177H – 11b1H 11B2H - 11B5H Header Register List Item Descriptor List Logging Timer setting The following are the details.
Page 231
The register list controls which Modbus registers are recorded in each historical log record. Since many parameters, such as Voltage, Energy, etc., take up more than 1 register, multiple registers are allocated for those parameters. For example: In order to record "Volts AN" into the historical log, Volts AN's Modbus address (4002H and 4003H) are assigned and programmed to the log record list so that information can be stored into the historical log registers.
Page 232
4) Logging Timer setting Modbus address 11B2H is used as the enable-disable logging timer select button for historical log 1. When enable is selected, historical log 1 records data at the time frame specified by the user. Bit value of 0 means to disable the logging timer setting, whereas bit value of 1 means logging timer setting is enable.
Page 233
the Max Records when the log has filled. This value will be set to 1 when the log is reset. Record Size: The number of bytes in this record, including the time stamp. The record's format in the meter is: record number(4bytes)+ time stamp(6bytes) + [data1~dataN](2Nbytes) + CRC(2bytes).
Page 234
Records number: The number of records that fit within a window. This value is settable, any number less than a full window may be used. This number tells the retrieving program how many records to expect to be fetched in the window. (record number x Record Size) = bytes used in the window.
Page 235
Note: If the logging timer is disabled, the first recording sector will be erased when the log is full. Therefore, user should not read the whole log when the used record numer is near to the max record number. Under this condition, user should read the "Used Records"...
