Object type: Bit-binary bit, Word-unsigned integer of 16 bit, Integer-Sign integer of
16 bit, Dwordunsigned integer of 32 bit
2.
Type of Access: R-Read only, Digital input Relay statue and Data are read by using of
function code 02, 01 and 03 respectively. R/W-Read and Write, Data is written by
using function code 16 and control command is written by using function code 05.
Writing to read only field is forbidden.
3.
Energy data is represented in 32 bit. Both high 16 bit and low 16 bit have successive
address alone. The high 16 bit data should be multiplied by 65536 and plus low 16 bit
data to get the energy data in master software. The unit is 0.1kwh or 0.1kvarh. It will
be clear to zero and start again when energy data accumulate to 1x109 kWh (kVarh).
The energy register can be cleared or preset over communication.
