Parameter setting items, setting ranges and contents of auto refresh, as well as the
buffer memory address of the master module which is used for exchanging data with
the CPU modules are shown below.
Set the parameters for the number of use of the A1SJ71PT32-S3/AJ71PT32-S3
master modules.

• Sets the total number of use of the master modules.
• Sets the head I/O number where the master module is
installed.
• MINI ...... In I/O mode (occupies 32 points)
• MINI-S3 ...... In expansion mode (occupies 48 points)
• Set only when MINI is set.
• In MINI-S3, since the number of master module's initial
ROMs becomes valid, the setting is not necessary.
(When the setting is executed, ignore it).
• Sets the devices to store the received/send data for
batch refresh.
• Specify the head number of the device.
• Occupies a part of the device area as the auto refresh
area from the head of the device for the number of
stations. (When setting the total number of remote I/O
stations to 64, occupies 8 points/station
stations=512 points: bit device.)
• Use of X/Y remote I/O range is recommended for
devices.
• Sets the number of retries upon the communication
errors occurrence.
• Error is not output when the communication is restored
within the number of the retries set.
