Address
GT Designer3 converts the device numbers into
decimal format according to the address map of the
energy measuring unit/electric multi-measuring
instrument to be used.
The table below shows the representations on the
MODBUS/RTU communication protocol and GT
Designer3.

Address conversion example
For monitoring the address "031AH" of holding register
(Current value of total power)
The address of the holding register is displayed as
"4*****" on GT Designer3.
GT Designer3 converts the holding register's address
"031AH" to "00794" in decimal format.
Then, "+1" is added to this decimal address since the
holding register's address on GT Designer3 always
starts from "1."
Therefore, the holding register's address "031AH" is
displayed as "400795" on GT Designer3.

GS device settings
Set the GS device as follows.
