parameters occupy two registers, to supplement this, the programmable
settings for the historical logs contain a list of descriptors. Each descriptor lists
the number of Modbus registers for the specified parameter. By combining
these two lists, the historical log record can be interpreted.
For example: Registers 4002H and 4003H are programmed to be recorded by
the historical log. Since 2 registers are used, the corresponding descriptor is set
as 2. These registers program the log to record “Volts AN.”
The historical log programmable settings are comprised of 3 blocks, one for
each log. Each log works identical to each other; therefore, only historical log
1 is described here. All register addresses in this section are shown within the
address range of historical log 1.
1100H-11DFH (Historical Log 1)
11C0H-127FH (Historical Log 2)
