(a) Mounting position of High Performance model QCPU or Process CPU
Up to four High Performance model QCPUs or Process CPUs can be mounted to
the slots of a main base unit, from CPU slot (the slot on the immediate right of
power supply module) through slot 2.
There must be no empty slot between CPU modules.
(b) Mounting position of Universal model QCPU (except for the Q02UCPU)
Up to three Universal model QCPUs (except for the Q02UCPU) can be mounted
to slot 0 to slot 2 of a main base unit.
(c) Mounting position of Motion CPU
1) Up to three Motion CPU modules (except for the Q172DCPU and Q173DCPU)
can be mounted to the slots, from the one located next to the programmable
controller CPU through slot 2, without any slot being left empty.
Any programmable controller CPU cannot be mounted on the right of the
Motion CPU.
2) When the main base unit is Q3 SB, Motion CPUs cannot be mounted.
