VARIABLES
Dat a a dd re ss e s
Both variables and groups of variables can be required. All the variables with consecutive addresses
can be required at one time. The following is the table with the addresses and the meaning of the
variables.
Address
HEX
0x325
0x329
0x32d
0x331
Note 1: The only writable value is 0x0000000 in order to reset the stored value.
Different values won't have effect.
The following table must be used to retrieve all information of the real time measurements.
The user can poll on both tables without any more operation, just change the Modbus address in the
protocol data message.
