Price Change Function; Customer Data Control - Sharp UP-800F Operation Manual Supplement

13. Price change function

When the price for an PLU/EAN item is changed at a machine (master or satellite), its PLU/EAN main file or
dynamic PLU/EAN file is updated by the new price data (unit price and associated department). Immediately
after this, the new data is automatically distributed to all other machines to update the PLU/EAN main files
or dynamic PLU/EAN files which contain the code of the item.
The data on an EAN item whose price has been changed at a satellite is also stored in the T-LOG buffer of
the satellite. The data stored in the T-LOG buffer is collected by T-LOG polling at the master to update its
PLU/EAN main file or dynamic EAN file.
For further information on the price change function, see the UP-800F/UP-810F instruction manual.
For the data flow, see the following figures.
• In case that the price is changed at the master:

• In case that the price is changed at a satellite:

If a transmission error occurs during automatic distribution of updated data to other machines after a
NOTE
price is changed using the price change function at a machine, the machine number of the terminal
which causes the error and the type of error are printed out at the sending machine. In this case, the
system retry function can be used if it is enabled. (For the system retry function, see page 63–64.)

14. Customer data control

In the IRC system, customer data is centrally controlled by the master. Customer data which is temporarily
stored in the T-LOG buffer of a satellite is sent to the master by T-LOG polling and controlled by the master.
(For further information on T-LOG polling, see page 19.)
