•
The existing AnS/QnAS (Small Type) main base unit can be used without modifying the wiring by replacing
with the extension base QA1S6�B and remounting the mounted modules.
The existing A (Large Type) extension base unit can be used without modifying the wiring by replacing with
the extension base QA6�B, and remounting the mounted modules.
• The QA1S6�B extension base unit cannot be used together with the A (Large Type) extension base A6�B/
A5�B) onto which QA6ADP is mounted.
When using a module mounted on the existing A (Large Type) extension base unit, replace the base unit
with the QA6�B extension base.
• Connect the base units in the following order.
Q Series main base unit
−>
Q Series extension base unit
−>
QA1S6�B extension base
−>
QA6�B
extension base
The GOT bus cannot be connected when the QA6�B extension base is connected.
The GOT bus can be connected when only the QA1S6�B extension bus is connected.
• Program modifications can be minimized by using the same I/O address for the existing units and setting the
current I/O addresses with the parameter I/O assignments.
• The following A/QnA (Large Type) module and AnS/QnAS (Small Type) module cannot be used with the Q
Series CPU.
These must be changed to a Q Series CPU compatible module.
CC-Link master/local module
MELSECNET/10 network module
Ethernet module, computer link module, etc.
• The QA1S6�B extension base and QA6�B extension base are only compatible with High Performance
Model QCPU or Universal Model QCPU (first five digits of serial No. "13102" or higher).
Basic Model QCPUs, Process CPUs, Redundant CPUs, Safety CPUs, and Remote I/O Stations are not
compatible.
Tip
1. The extension base unit equipped with QA1S6ADP must be installed in the first extension stage.
Since QA1S6ADP does not have an extension cable connector (OUT), it cannot be connected to the base
unit in the second extension stage or higher.
Therefore, when QA1S6ADP is used, the system consists of 2 base units, Q Series main base unit and
AnS extension base unit equipped with QA1S6ADP.
To replace only the CPU with Q Series, it is required to use the QA1S extension base unit. Refer to Item
3.2.1.
2. When the existing A/AnS Series modules are used, the program can be used without changing the
existing I/O addresses through I/O assignment by parameters.
For the detailed procedures for setting the I/O addresses through I/O assignment, refer to Section 3.3.
3. The AnS extension base unit equipped with QA1S6ADP can be used with a high performance model
QCPU or universal model QCPU (the first 5 digits of the serial number must be "13102" or later).
The modules which can be installed in the AnS extension base unit equipped with QA1S6ADP are the
same as those installed in the QA1S extension base unit. For details, refer to "Transition from MELSEC-
AnS/QnAS (Small Type) Series to Q Series Handbook (Fundamentals)."
Tip
3.2.2 Replace main base unit with Q Series and use existing extension base unit and modules in it
(use QA1S conversion adapter)
It is possible to replace the modules including the CPU on the main base unit with Q Series
modules and use the existing input/output modules and extension base unit.
This can reduce the working hours for drilling and wiring modification.
