3.3.2 CPU module combinations and mounting positions
This section describes the combinations and mounting positions of CPU modules when a Universal model QCPU is
used as CPU No.1.
Note that the CPU modules that can be mounted differ depending on the main base unit used. ( Page 53, Section
3.3.1)
(1) Combinations
*1 A C Controller module and a PC CPU module cannot be mounted on the same main base unit.
*2 The Q00UCPU, Q01UCPU, and Q02UCPU can be used only as CPU No.1.
*3 The module and a C Controller module (Q12DCCPU-V, Q24DHCCPU-V, Q24DHCCPU-LS) cannot be mounted on the
same main base unit.
*4 When the Q172DCPU(-S1), Q173DCPU(-S1), Q172DSCPU, or Q173DSCPU is used, only the following CPU modules
can be mounted on the same main base unit.
• Universal model QCPU (except the Q00UCPU, Q01UCPU, and Q02UCPU)
*5 A QnUDVCPU and a C Controller module (Q06CCPU-V or Q06CCPU-V-B) cannot be mounted on the same main base
unit.
*6 A QnUDVCPU and a PC CPU module cannot be mounted on the same main base unit.
