2. SYSTEM CONFIGURATION
2.1 System Configuration
This section describes the system configuration and restrictions when
the QA6ADP is used.
(1) The QA6ADP+A5B/A6B is only applicable for the following
CPU modules.
• High Performance model QCPU
• Universal model QCPU whose serial number (first five digits) is
"13102" or later
(2) Mount the Q5B/Q6B, QA6B, and QA6ADP+A5B/A6B in
order from the nearest position of the main base unit.
The QA6ADP cannot be used in combination with the QA1S5B or
QA1S6B.
(3) The number of slots of the QA6ADP+A5B/A6B is always
displayed in 8 slots, regardless of the number of slots of the
extension base unit to be used in combination with the QA6ADP.
Assign the I/O number of a module, putting each series in block
and in order of "Q series

A series" or "A series

Q series".
Failure to do so may cause an error (SP.UNITLAY ERR).
In addition, do not duplicate the I/O number.
(4) For the extension stage number setting of the extension base unit,
set stage number (the first to seventh stages) to extension stages
from the one nearest to the main base unit.
(5) An extension cable connectable to the QA6ADP is the Q series
extension cable only.
(6) Set the same stage number to both the stage number setting
connector of the extension base unit and that of the QA6ADP.
(7) The QA6ADP+A5B/A6B cannot be used as the MELSECNET/
H remote I/O station.
