Serial number
4�10�3�7� 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.
