3.2 Replace AnS/QnAS (Small Type) Series with Q Series
Tip
• 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

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).
