9. Look-up and updating of the GLU/PBLU file
In the IRC system, the following two types of GLU/PBLU file allocation system: a centralized
system and an individual system.
(1) Centralized GLU/PBLU file system
In this system, the GLU/PBLU file exists only in the master. All satellites in the IRC system can
access the GLU/PBLU file in the master for registration.
GLU/PBLU-file-related inline communications are made for the following purposes:
• New order or reorder
• Payment entry or temporary finalization
• Bill printing
• Slip printing
• Bill transfer/bill totalizing
• Bill separate
There are two types of GLU/PBLU data transmission.
1) The GLU/PBLU data is transmitted from the master to a satellite for GLU/PBLU file look-
up (in case of a new order/reorder). In this case, the GLU/PBLU reserve counter* is
retained at the master.
* The reserve counter reserves some records of GLU/PBLU files to prevent a “LACKING MEMORY” error in
finalization.
2) The GLU/PBLU data is transmitted from a satellite to the master for finalization of a
transaction (in case of payment entry or temporary finalization).
The data transmitted from the satellite is once saved in the GLU/PBLU data receiving file
and then in the GLU/PBLU file. In this case, the GLU/PBLU reserve counter is cleared at
the mater.
If a satellite looks up the GLU/PBLU file in the master or asks the master to update the
file, the backup master performs the same process as the master.
(2) Individual GLU/PBLU file system
In this system, the master and satellites have their own GLU/PBLU files and look up them for
registration. Therefore, no inline communications are made regarding GLU/PBLU data.
