2.2 Cautions on system configuration

(1) About the combination of modules used
Always use the AJ65BT-RPI-10A/10B in such a configuration that
the lens surfaces of the A and B modules are opposed.
There are no restrictions on the sequence of connections.
(Either the A or B module may be placed on the master station
side.)
(2) Conditions of usable master module
When the AJ61BT11, A1SJ61BT11, AJ61QBT11 and
A1SJ61QBT11 modules are used, those of the functional version B
or later must be employed. Use the master module bearing the

(3) Max. number of modules connected to configure CC-Link system
Up to 64 modules of repeaters can be connected in one segment.
In the CC-Link system where repeaters are used, also the number
of remote stations capable of being controlled by one master
station is the same as in the other systems.
For details, refer to the User's Manual of the applicable master
module.
(When the monitor function is used in these modules, they must be
counted not as repeaters but as remote I/O stations.)
