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.
Holding register
"4 00794" +1
"400795"

