6.6 MPP memory expansion boards

Terminals equipped with the MPP option (Permanent Weight Memory)
can save the weight data of each single weighing operation in a
permanent memory or print a paper record (type-approved printer) and
transmit the values to a peripheral device, along with an identification
code that is automatically assigned by the terminal.
In the case of printing the data (on a type-approved printer), it is not
necessary to install the internal optional board. By entering the
identification code on the terminal or by checking the paper records, it is
possible to verify that the data are correct. The identification number
comprises 7 digits, which means that the number will be repeated after
10.000.000 weighing operations.

6.6.1 Memory capacity

The memory capacity of the MPP expansion board is sufficient to store
the data for approximately 130,000 weighing operations (weight + tare),
which corresponds to around 8 months of continuous use of the
terminal, performing 500 weighing operations per day.
If the terminal is used less frequently, this period will be extended.

CAUTION
When maximum memory capacity is reached, the oldest data
are deleted and replaced by the most recent.

6.6.2 Operation
The type of MPP operation is defined during installation.
There are two main types of operating mode (for further details see the
advanced user manual):

✔ in the first type, the user operates from the terminal by pressing
to save and transfer the weight data;
✔ in the second type, the user works from the PC keyboard in the way
determined by the specific software.

1-59
 D400
In both operating modes, on completion of the saving operation, the user
can display the progressive number associated with the weighing
operation (see par. 6.6.4 on page 1-61 ).
Code MPP will only appear on the display when the memorising
operation is enabled with the key.
Both the weighing terminal and the PC may signal errors caused by
failure to transfer or save the data correctly. In this event, follow the
on-screen instructions.

6.6.3 Disabling MPP

It may sometimes occur that you do not wish to transfer the weight data
or save it in the MPP memory.
In this case, to disable MPP, type:
2°F>MPP>DISABLED>SELECT>ESC>ESC

To subsequently re-enable MPP operation:

2°F>MPP>WITH MEMORY>SELECT>ESC>ESC

WARNING
Disabling MPP may compromise the operation of equipment
connected to the weighing system in that data transfer to
such equipment will be inhibited.

1-60
 D400

6.6.4 Checking memorised weight data

To check the weight saved in memory proceed as follows:
2°F>CODMPP
The terminal displays the net weight and the tare associated with the
MPP identification code of the last weighing operation to be performed.
By pressing SETCOD you can call up previous weighing operation data
by entering the relative code number (see par. 5.1.2 on page 1-38 ).

If the terminal is equipped with a printer, by pressing you can print

the weight data displayed and the relative identification code.
