MULTIPLE CPU SYSTEM CONCEPT
(4) When CPU No.1 is Universal model QCPU
The mounting position of each CPU module is shown in Table 13.7 and Table 13.8.
(a) Mounting position of Universal model QCPU
Only one Q02UCPU can be mounted on the CPU slot (the slot on the immediate
right of power supply module).
Up to four Universal model QCPUs (other than the Q02UCPU) can be mounted
on the slots of a main base unit, from the CPU slot to slot 2.
(b) Mounting position of High Performance model QCPU or Process CPU
When using the Q02UCPU, mounting High Performance model QCPUs or
Process CPUs is not allowed.
When using any other than the Q02UCPU, up to three High Performance model
QCPUs or Process CPUs can be mounted to the slots of a main base unit, from
slot 0 to slot 2.
(c) Mounting position of Motion CPU
1) When the main base unit is Q3 B
When using the Q02UCPU, only one Motion CPU (except for the Q172DCPU
and Q173DCPU) can be mounted on slot 0.
When using any other than the Q02UCPU, Motion CPUs cannot be mounted.
2) When the main base unit is Q3 SB
Motion CPUs cannot be mounted.
3) When the main base unit is Q3 DB
When using the Q02UCPU, Motion CPUs cannot be mounted.
When using any other than the Q02UCPU, up to three Motion CPUs (the
Q172DCPU and Q173DCPU only) can be mounted on the slots of the main
base unit, from slot 0 to slot 2.
Any High Performance model CPU or Process CPU cannot be mounted on the
right side of the motion CPU.
(d) Mounting position of C Controller module
When using the Q02UCPU, only one C Controller module can be mounted on slot
0.
When using any other than the Q02UCPU, up to three C Controller modules can
be mounted from the slot on the immediate right of the CPU module to slot 2,
without any slot being left empty.
Any programmable controller or Motion CPU cannot be mounted on the right side
of a C Controller module.
