(2) When a High Performance model QCPU is used
*1 "Number of CPU modules" indicates the number set in "No. of PLC" of PLC parameter ("Multiple CPU Setting").
*2 When a module occupying two slots is mounted, the maximum number of mountable I/O modules is the number
obtained by "65 - (Number of CPU modules + 1)".
When a module occupying three slots is mounted, the maximum number of mountable I/O modules is the number
obtained by "25 - (Number of CPU modules + 2)".
*3 If a Motion CPU or PC CPU module is used in a multiple CPU system, the Q3RB, Q6RB, and Q6RP cannot be
used.
*4 Available version differs for some intelligent function modules. ( Manual for the intelligent function module used)
*5 When a CPU module occupying two slots is mounted, the slot on the right of the CPU module will be 10

.
*6 When the QA1S6ADP+A1S5B/A1S6B is used, the maximum number of extension base units is 1, and the maximum
number of I/O modules that can be mounted is 20 minus the number of CPU modules. When the QA1S6ADP-
S1+A1S5B/A1S6B is used, the maximum number of extension base units is 3, and the maximum number of I/O
modules that can be mounted is 36 minus the number of CPU modules.

Restrictions on number of
mountable modules
The number of mountable
modules differs depending on the
CPU module type.
The number of mountable
modules per system and the
number of controllable modules
per CPU module differ depending
on the CPU module type.
