(2) When the system retry function is enabled
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.
