In the IRC system, the following two systems for PLU/EAN data control are available: a centralized system
and an individual system.
In choosing the type of PLU/EAN data control system, please consult your authorized SHARP dealer.
Centralized system
PLU/EAN sales data is centrally controlled by the master. PLU/EAN sales data which is temporarily stored
in the T-LOG buffer of a satellite is sent to the master by T-LOG polling.
Individual system
The master and satellites control their own PLU/EAN sales data. PLU/EAN sales reports can be individually
generated at each machine. Consolidation of PLU/EAN sales data can be achieved by generating the
consolidated PLU/EAN report at the master.
The learning function enables the operator at a satellite to set the unit price, associated
department and deletion/non-deletion choice for an item whose code is undefined in the
PLU/EAN file, and to register the transaction in the training mode. (For further information on the
learning function, see the UP-820F/UP-820N Instruction Manual.)
If the satellite has no dynamic EAN file, the data on the EAN item which has been set using the
learning function is stored in the PLU/EAN main file to update the file.
If the satellite has a dynamic EAN file, the data is stored in the dynamic EAN file to update the file.
The data which has been set using the learning function in the training mode at a satellite is also
stored in its T-LOG buffer.
For the data flow, see the following figures.
