If a transmission job from the master to a satellite is not performed successfully, the master either
terminates the job immediately or awaits a command given through the keyboard, depending on whether the
system retry function is disabled or enabled. When the system retry function is enabled, the master awaits
entry of a command and retries access depending on the commands as explained on the following page.
System retry function is also available at satellites depending on a transmission error.

This function is used in the following cases:

• The master has failed to download preset or updated data to all or some of the satellites.
• The master has failed to collect sales report data from all or some of the satellites.
• The satellite has failed to download data to other machines.
• A clerk has failed to sign off at a satellite.*

Whether the system retry function is enabled or disabled when a transmission error occurs is
programmed both at the master and a satellite. (See “5. Specifying whether to enable or disable the
system retry function when a transmission error occurs” on page 43.)

*When a clerk has failed to sign off at a satellite for some reason (e.g. the master is busy), the RETRY

and ABORT commands are available but the IGNORE command is not.

The master terminates the transmission job immediately in the following two ways.
If none of the satellites have successfully transmitted data, the transmission is regarded as having
ended with an error, which is equivalent to ABORT as discussed on the following page.
If there is any satellite which has successfully transmitted data, the transmission is regarded as either
successful or unsuccessful depending on the type of transmission job. In this case, the transmission
regarded as successful and the one regarded as unsuccessful are equivalent to IGNORE and ABORT,
respectively, both of which are explained on the following page.

If a transmission error relating to a satellite occurs, the relevant window will appear on the display of
the master and the master awaits entry of one of the following commands given through the keyboard:

A) RETRY command (selection from the menu or press of the 1 key)
B) ABORT command (selection from the menu or press of the 2 key)
C) IGNORE command (selection from the menu or press of the corresponding key; 2 or 3 key)

A) RETRY command:

When RETRY is selected, the master retries to access the satellite; however, depending on the
type of error (command error, etc.), it is obvious that the master would fail to access it again. If this
type of error occurs during transmission, the master may not retry.

B) ABORT command:

When ABORT is selected, the master terminates access to the satellite and regards the
transmission as having unsuccessfully ended. However, in the case of program data downloading,
the ABORT command may be issued only when all the satellites accessed are in the error state.

C) IGNORE command:

When IGNORE is selected, the master terminates access to the satellite, regards the transmission
as having successfully ended and prints only transmitted data.
If no satellites have successfully transmitted data, the IGNORE command may be issued to the
master in the case of sales data inquiry (X report), though the result is not printed.

[Retry during sales data inquiry]

During resetting, the ABORT command may be given only when every accessed satellite is in the
error state. The IGNORE and RETRY commands are available unconditionally.
