• The I/O addresses do not need to be changed when reutilizing existing A (Large Type) and AnS
(Small Type) modules with Q Series CPU and mounting the modules on QA6�B/A6�B
+
QA6ADP
or QA1S6�B. This can greatly reduce program modification time.
• The A (Large Type) and AnS (Small Type) modules can be used with the same I/O addresses, so
there is no need to change the external wiring numbers.
Solution and Benefit
(1) I/O assignment example
●
System configuration example (same as in 3.1.1)
When utilizing existing A (Large Type) and AnS (Small Type) modules with the Q Series CPU, set the existing
module’s I/O addresses to the existing addresses with the PC parameter I/O assignment settings. Assign the
addresses for the modules mounted onto the main base unit after the existing module. This will greatly reduce
program modification time.
The following is an example of how to reuse the program without modifying the I/O addresses when replacing the
CPU with a Q Series CPU and keeping the existing I/O modules on a QA extension base unit.

Tip
• Assign the I/O numbers in the following order: Q Series to A Series or A Series to Q Series.
• When the order is mixed (i.e., Q Series
-> A Series -> Q Series), the CPU does not start up due to an error.
