5.4.4 System configuration

This section explains the system configuration and precautions for use of the QA(1S)6B and
QA1S51B type extension base unit.
(1) Connection order of extension base units
When using the Q6B, QA1S6B, QA1S51B, and QA6B together, connect them in the order of the
Q6B, QA1S6B, QA1S51B, and QA6B from the nearest position of the main base unit.
The QA1S51B is not extendable. When the QA1S51B is used, the QA6B cannot be used.
(2) Connection order of extension base units upon setting the extension stage number
To use extension base units, it is necessary to set extension stage numbers (1 to 7) with the stage
number setting connector.
Set the extension stage number 1 to the connected extension base unit closest to the main base unit,
and the following extension stage number (up to 7) to the following extension base units in the
connected order.
