Table 4.27 Relay address

Relay Statue and Control

Function code: 01 for Reading, 05 for Controlling

Addr. Parameter Range Object Type Type of access

0000H Relay1 1:ON , 0:OFF bit R/W

0001H Relay2 1:ON , 0:OFF bit R/W

1.Object type: Bit-binary bit, word-unsign integer of 16 bit, Integer-Sign integer

of 16 bit, Dword-ungign integer of 32 bit

2.Type of Access: R-Read only, Digital input Relay statue and Data are read

by using function code 02, 01 and 03 respectivly. R/W-Read and Write, Data

is writen by using function code 16 and control command is writen by using

function code 05. Writing to read only field is forbiden.

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

accumulat to 1x10

kwh(kvarh). The energy register can be cleared or preset

through communication.
