When reusing existing modules with a Q Series CPU, it is not required to change the I/O number of the existing
modules. For new module(s) on the main base unit, assign a number after the existing modules in the I/O assignment
settings. This can greatly reduce the program modification time.
●Remove the AnS/QnA extension base unit
(QA1S□B) when all modules have been replaced
with Q Series equivalents.
Existing AnS/QnAS Series
Step 1
■Gradual transition from Ans/QnAS Series to Q Series (Q mode).
●Construct a system that is controlled by the new Q Series CPU (Q mode) while keeping the existing AnS/QnAS
Series modules mounted to a QA1S□B extension base unit. The AnS/QnAS Series modules can gradually be
replaced to fully establish a Q Series system.
●The QA1S□B extension base units are compatible with High Performance Model QCPUs and Universal Model QCPUs
whose first five-digit serial number is 13102 or later. Basic Model QCPUs, Process CPUs, Redundant CPUs, Safety
CPUs and Remote I/O Stations are not compatible.
●Some modules cannot be mounted on the QA1S□B extension base units. For details, see the "QCPU User's Manual
(Hardware Design, Maintenance and Inspection) (SH(NA)-080473ENG)".
●No further extensions can be made to QA1S51B as it has not got an Extension Cable Connector.
This unit cannot be used in conjunction with QA6□B and QA6ADP with A5□B nor can QA6ADP be used in
conjunction with A6□B.

Existing AnS/QnAS Series power

it is.
■Reduce conversion effort by using the same I/O addressing.
Use existing AnS/QnAS Series modules
when upgrading to QCPU.

Replace modules which cannot be mounted with Q Series modules.
Note: Assign the I/O numbers in the following order: Q Series to AnS/QnAS Series or AnS/QnAS Series to Q Series.
When the order is mixed (i.e., Q Series → AnS/QnAS Series → Q Series), an error will occur in the CPU.
