Variables available from version C11.1006.230203.
8.3.9.- DEVICE CONFIGURATION VARIABLES
The Functions 0x04 and 0x10 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.
