4.2 Operation Settings
4.2.2 Parameter settings
Item Description Default
No. of PLC
Set the number of CPU modules mounted on the main base unit in the
multiple CPU system. The number of modules differs depending on the CPU
module used as CPU No.1 and the main base unit used. ( Page 31,
CHAPTER 3)
This parameter must be set.
1
Host Station
Set this parameter to check the host CPU number in the multiple CPU system.
If this parameter is set, each CPU module checks its own CPU number with
the one set in this parameter to see if they match.
• When "No Specification" is selected, the host CPU number is not checked.
• Host CPU numbers do not need to be set to all the CPU modules in the
system.
• To set the same "Multiple CPU Setting" parameters to all the CPU modules
used in the multiple CPU system, select "No Specification". Parameter
settings are shared by all the CPU modules used in the system.
The host CPU number can be checked when one of the following CPU
modules is used.
• Universal model QCPU (except the Q00UCPU, Q01UCPU, and Q02UCPU)
• Motion CPU (Q172DCPU(-S1), Q173DCPU(-S1), Q172DSCPU, or
Q173DSCPU)
• C Controller module (Q12DCCPU-V, Q24DHCCPU-V, or Q24DHCCPU-LS)
No Specification
Operation Mode
Select whether to stop or continue the operation of all the CPU modules when
a stop error occurs in a CPU module. Set this parameter to continue the
operation of other error-free CPU modules if a stop error occurs in a CPU
module other than CPU No.1.
For example, if the "All station stop by stop error of PLC2" checkbox is
unchecked, other CPU modules continue their operation even after a stop
error occurs in CPU No.2.
The operation mode of CPU No.1 cannot be changed. ( Page 102,
Section 4.6)

Multiple CPU Synchronous
Startup Setting
Set this parameter to enable synchronous startup of the CPU modules in the
multiple CPU system. ( Page 168, Section 6.5)
Only Universal model QCPUs support this parameter.
Uncheck the checkbox of the corresponding CPU number if any of the
following CPU modules is used.
• High Performance model QCPU
• Process CPU
• C Controller module (Q06CCPU-V or Q06CCPU-V-B)
• PC CPU module
