9. PLU/UPC data control
In the IRC system, PLU/UPC sales data is centrally controlled by the master. PLU/UPC data
which is temporarily stored in the T-LOG buffer of a satellite is sent to the master by T-LOG
polling. (For further information on T-LOG polling, see page 14.)
NOTE
The learning function enables the operator at a satellite to set the unit price, associated department
and deletion/non-deletion attributes for an item whose code is undefined in the PLU/UPC file. (For
further information on the learning function, see the UP-600 or UP-700 Instruction Manual.)
If the satellite does not have a dynamic UPC file, the data on the UPC item which has been set using
the learning function is stored in the PLU/UPC main file to update the master’s file.
If the satellite has a dynamic UPC file, the data is stored in the dynamic UPC file to update the
master’s file.
The data which has been set using the learning function in the training mode at a satellite is stored in
its T-LOG buffer.
For the PLU/UPC data flow, see the following scenarios.
(1) When the master and satellites have no dynamic UPC files:
(2) When the master has a dynamic UPC file and satellites don’t:
(3) When both the master and satellites have dynamic UPC files:
