If the bit corresponding to the number of the slave to be communicated with and
Y13 are turned ON, data in this area will be registered in the QJ71AS92 and be
reflected into the List of projected slaves (LPS (for read)) (buffer memory
address: 19
H
to 1C
H
).
(Related item: Section 4.5 (2))
TIP
• The projected slave list (LPS (for write)) is handled as a 64-bit length in the
QJ71AS92. Therefore, if data is written to only the buffer memory address 49
H
,
the contents of the buffer memory address 4A
H
to 4C
H
are also made valid as
data.
• When communicating with the slave that has been judged as ready for
communication in the active slave list (LAS) (buffer memory addresses: 15
H
to
18
H
), easy registration of the projected slave list (LPS (for read)) and configuration
are enabled by using the command buffer <request> 201
H
.
