10. Price change function

When a price for the UPC item is changed at a machine (master or satellite), its PLU/UPC main file or dynamic PLU/UPC file is updated by the new price data (unit price and associated department).

The new data is then automatically distributed to all other machines to update the PLU/UPC main files or dynamic PLU/UPC files which contain the code of the item.

The data on an UPC 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 the T-LOG polling after the open-store operation at the master to update its PLU/UPC main file or dynamic UPC file.

For further information on the price change function, see the UP-600 or UP-700 instruction manual.

For the PLU/UPC price change data flow, see the following scenarios.

Saving

If a transmission error occurs during the automatic distribution of the updated data to other machines after a price is changed, the machine number of the terminal which caused 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 57.)

11. 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 after the open-store operation and is controlled by the master. (For further information on T-LOG polling, see page 14.)
