Registers: The number of registers to log in the record range from {0-117}. The
size of the record in memory is [12 + (Registers x 2)].
Sectors: The number of memory sectors allocated to this log. Each sector is
64kb in size. 100 sectors are available for allocation among the three historical
logs. Valid allocation range is from 0~100 (When the sector is set 0,this log is
disable).
Interval: The data capture interval for historical log records. Valid time interval
can be set from 0-1440 minutes. When the interval is set to 0, this log is disable.
Note:
When sectors or Register or Interval is zero ,this log is disable.
2) Register List:
Registers: 1102H-1176H
Size: 1 or 2 register(s) per parameter, 117 available registers per historical log.
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.
• Each unused register item should be set to 0000H or FFFFH to indicate no
parameters are associated with them.
• The actual size of the record, and the number of items in the register list which
are used, is determined by the registers in the header.
• Valid register address ranges that can be recorded in the historical log registers
are 4000H-412BH, 4294H-42A8H, 4349H-4398H, 4500H-461BH, 4620H-463DH.
