METER DATA
The "METER DATA" system allows the import of data up to level 4, included, (working and factory parameters of the
card) of the converter to another device and the restoration of the data of a meter in case the electronic card needs to be
replaced .
Operation:
during normal operation the meter saves all data, including the dynamic data of the totalizers, every hour, on
a specific file on the SD card. The file is incremental, so its length increases linearly over the time. Each recording is time-
stamped for future use. Currently, automatic data recovery uses only the last valid recording in chronological order.
Data reset:
The reset is done manually, after inserting the SD card taken from the meter to be replaced, on the new
electronics to be used as a replacement. This operation must be done strictly with the electronics off. Once the SD card
has been replaced, wait for the device to restart and connect the MCP interface via the USB connection. Then select the
“Data recovery” function on the “Functions” menu and confirm. Wait for the device to restart (the time required will depend
on the configuration and the presence or absence of operations with the modem, if installed).
Consequences of restoring data on the SD card:
the new electronic card will acquire all the existing data from the
old meter. The root directory of the old card will be renamed with the serial number of the new card and no existing data
will be altered. The data that belonged to the new card that may have been created during the recovery (data logger
or events) are stored in a root directory with the name “<new card series number> .OLD”. In any case, no data will be
overwritten or deleted.
Limits of data saving and retrieval: Data recovery is possible with the following limitations:
The new board to be used as a replacement must have the same hardware configuration as the one to be replaced.
If the device to be replaced is MID, the new board to be used as a replacement must already be preconfigured as
MID, with the appropriate functions locked and the CRC comparison value set correctly.
It is NOT possible to recover any passwords saved for internet connection services (email, FTP, etc.). These will
need to be re-entered manually or via a separate configuration file. Restoring data does NOT involve resetting any
passwords that may have been pre-configured in the new card.
It is NOT possible to recover the passwords relating to the access levels of the instrument. Also in this case they will
be re-set manually or pre-configured in the new board.
The data relating to the hardware calibrations of the board are NOT transferred, therefore those stored in the new
board remain valid.
The following data are NOT recoverable:
Function parameters accessible with level 5 and 6 (typically hardware calibration data)
Passwords and others encrypted data
Hardware configuration parameters
Enable status of the functions selected for the "quick-start" menu
System function enable status
The recovered data are also saved simultaneously in the “FACTORY DEFAULTS” memory and they become the new
factory standard values of the board.
