When the close store operation is performed at the master, the IRC system is closed. POS can send AT
command by this job. This function controls a modem, but doesn’t have control over registration and T-LOG.
The procedure for the close store operation is as follows.
Select “CLOSE STORE” from the OPXZ mode window and press
the
e
key.
• You can also perform the close store operation at each satellite.
• When the close store operation is performed, the data remaining in the T-LOG buffers of all the
satellites is collected by the master.
• When a transmission error occurs during the close store operation, the operation is regarded
as normally terminated if the system retry function* has been disabled by programming. When
the master has been programmed to enable the system retry function, it displays the machine
number of the satellite that has encountered the error. Selecting the displayed machine
number will display a prompt to retry the close store operation.
* For the system retry function, see page 63–64.
