The parameter-set number of CPU
modules differs from the actual
number in a multiple CPU system.
Match the number of (CPU modules in
multiple CPU setting) - (CPUs set as
empty in I/O assignment) with that of
actually mounted CPU modules.

Multiple CPU setting or control CPU
setting differs from that of the
reference CPU settings in a multiple
CPU system.

Multiple CPU automatic refresh setting
is any of the followings in a multiple
CPU system.
• When a bit device is specified as a
refresh device, a number other than
a multiple of 16 is specified for the
refresh-starting device.
• The device specified is other than
the one that may be specified.
• The number of send points is an odd
number.
Check the following in the multiple
CPU automatic refresh parameters
and make correction.
• When specifying the bit device,
specify a multiple of 16 for the
refresh starting device.
• Specify the device that may be
specified for the refresh device.
• Set the number of send points to an
even number.

In a multiple CPU system, the multiple
CPU automatic refresh setting is any
of the following.
• The total number of transmission
points is greater than the maximum
number of refresh points.
Check if the following settings have
been made in the refresh setting of the
multiple CPU setting, and correct the
settings as necessary.
• The total number of transmission
points is within the maximum
number of refresh points.

• In a multiple CPU system, the online
module change parameter (multiple
CPU system parameter) settings
differ from those of the reference
CPU.
• In a multiple CPU system, the online
module change setting is enabled
although the CPU module mounted
does not support online module
change.
• Match the online module change
parameter with that of the reference
CPU.
• If the CPU module that does not
support online module change is
mounted, replace it with the CPU
module that supports online module
change.
