All the Modbus map addresses are hexadecimal.
The
0x04 function
is implemented for this variable.
This variable indicates the quadrant in which the device is operating.

Device configuration variables.
All the Modbus map addresses are hexadecimal.
The
0x04
and
0x10 functions
are implemented for this variable.
The device’s Modbus function does not check whether the variables recorded are within the
correct margins, they are only checked when they are read from the EEPROM. So if any
parameter is recorded with an incorrect value the device will be configured with its default
value.
The Modbus configuration will not take effect until the device is reset.
