DFW series indicators DFW_03_12.07_EN_U

By pressing any key the connection is disabled (the next step in the menu is displayed); to reactivate it, one has to select
the “PC.Conn” step and press ENTER/PRINT.
Example of connection to the PC:
DFWPM10USB (MASTER) connected to PC; “PC.SEL” parameter set to 2 (TECH.MAN.REF.).
- If the “yES” mode has been selected, the indicator communicates by radio with the PC on the serial port 2: in this case, a
radio module has to be connected to the PC.
- If the “yES.dir” mode has been selected, the indicator communicates with the PC on the serial port 1: the connection
between indicator and PC has to be made directly through a USB cable.
11.6.6 TURN OFF THE MASTER AND THE SLAVES
If the MASTER displays the sum of the weights:
- by pressing at length the C key on the MASTER it is possible to turn off only this indicator.
- by pressing at length the C key on a SLAVE it is possible to turn off only that indicator: after a few instants the MASTER
displays the “ECo n” message in which n is the number of the SLAVE that has been turned off and then the weight
transmitted by the next detected SLAVE.
If the MASTER displays the weight transmitted by a SLAVE:
- by pressing briefly the C key on the MASTER this is repeated on the active SLAVE.
- by pressing the C key on the MASTER until the “-0FF-“ message is displayed, it is possible to turn off the active SLAVE;
the “-0FF-“ message is displayed on the MASTER for a few seconds, then it displays the “ECo n” message in which n is
the number of the SLAVE that has been turned off and then the weight transmitted by the possible next detected SLAVE.
Note: while the “-0FF-” message is displayed it is possible to turn off the MASTER by pressing again at length the C key.
- by pressing the C key on the MASTER until the “-0FF-“ message is displayed for the second time it is possible to turn off
only the MASTER indicator.
- by pressing at length the C key on the active SLAVE it is possible to turn off only that indicator: the MASTER displays the
“-0FF-“ message and then the “ECo n” message in which n is the number of the SLAVE that has been turned off; then the
MASTER displays the weight transmitted by the possible next detected SLAVE.
- by pressing at length the C key on a SLAVE that is not active it is possible to turn off only that indicator.
It is also possible to turn off only the MASTER indicator while it displays the “ECo n” message, by pressing at length the C
key. If the auto-off is set on MASTER indicator, it works only while the MASTER indicator displays the “ECo n” message.
11.7 ALIBI MEMORY (ALibi) (OPTIONAL)
The alibi memory allows to store the transmitted weight values in the computer for data processing and/or integration. The
stored values may then be recalled from the PC serial line or directly on the indicator’s display for a following check.
The storage of a weigh takes place either following the reception of the serial command or following the pressure of the
ENTER/PRINT key: the indicator transmits on the PC serial line the gross and tare weights and an ID which clearly
identifies the weigh.
The ID has the following format:
<Rewriting number> — <Weigh number>
- Rewriting number: number of 5 digits which may go from 00000 to 00255; it indicates the number of complete
rewritings of the alibi memory.
- Weigh number: number of 6 digits which may go from 00000 to 131072; it indicates the weigh number in the current
rewriting of the alibi memory
With each storage the weigh number is increased of 000001; when this reaches the 131072 value, it restarts from 000000
and the rewriting number increases of 00001.
Therefore the weigh relative to an ID may be verified just if:
-
it has a rewriting number equal to the current one of the alibi memory and a weighing number equal or less than the last
value received with the “PID” command;
- it has a rewriting number equal or greater than zero, but less than 1, in comparison to the current value of the alibi
memory, and a weigh number greater than the last value received with the “PID” command.
