Manual Integrator Supercal 531 06-06-2011 19
4. Data Storage
4.1 Data storage over EEPROM
The Supercal 531 has two non-volatile EEPROMs for storing data. The data are updated every
hour in the non-volatile EEPROM of the upper part of the Integrator (MET).
Thus, the data backup is kept even in case of power supply failure. All data are updated and stored
automatically.
The first non-volatile memory is located on the PCB of the integrator in the calibration- and meas-
uring-relevant upper part (MET):
Integrator upper part (MET):
Integrator - configuration parameters
Accumulated energy
Accumulated volume
Accumulated values of the additional meters A1 and A2
Customer-specific tariff 1 (and tariff 2)
15 monthly values
32 maximum values
32 average values
2 set days
Accumulated energy or volume on set day
Operating hours
Date and time
Serial number MET*, integrator upper part
Pulse factor of flow sensor
Error history (last 10 errors)
Alarm limits and threshold values
Tariff functions
The second non-volatile memory is located on the circuit board of the integrator base part. Thus
the configuration for the data communication as well as the customer ID is kept even if the calibra-
tion- and measurement-relevant upper part has to be replaced. Here, the following data are stored:
Integrator lower part (MIO):
Serial number MIO* integrator base part
ID number / customer ID
Pulse factor of the additional meters A1 and A2
Unit of the additional meters A1 and A2
M-Bus (primary and secondary)
Baud rate (M-bus)
Radio address
Pulse factor pulse output
Parameterisation of the optional modules
* MET: Metrological
* MIO: Module Input Output
