(SD0)
The parameter-set number of CPU
3010 modules differs from the actual number
in a multiple CPU system.
Multiple CPU setting or control CPU
3012 setting differs from that of the reference
CPU settings in a multiple CPU system.
Multiple CPU auto 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.
In a multiple CPU system, the multiple
CPU auto refresh setting is any of the
following.
• The total number of transmission
points is greater than the maximum
3013
number of refresh points.
In a multiple CPU system, the multiple
CPU auto refresh setting is any of the
following.
• The device specified is other than the
one that may be specified.
• The number of send points is an odd
number.
• The total number of send points is
greater than the maximum number of
refresh points.
• The setting of the refresh range
crosses over the boundary between
the internal user device and the
extended data register (D) or
extended link register (W).
*4 The module whose first 5 digits of serial No. is 04012 or later.
*5 The module whose first 5 digits of serial No. is 07032 or later.
*6 The MELSECNET/H module whose first 5 digits of serial No. is 08102 or later.
*7 The module whose first 5 digits of serial No. is 09012 or later.
*8 The Universal model QCPU except the Q02UCPU.
*9 The module whose first 5 digits of serial No. is 10042 or later.
Corrective Action
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.
Match the multiple CPU setting or
control CPU setting in the PLC
parameter with that of the reference
CPU (CPU No.1) settings.
Check the following in the multiple CPU
auto refresh setting 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.
Check the following in the multiple CPU
auto refresh setting and make
correction.
• The total number of transmission
points is within the maximum number
of refresh points.
Check the following in the multiple CPU
auto refresh setting and make
correction.
• Specify the device that may be
specified for the refresh device.
• Set the number of send points to an
even number.
• Set the total number of send points
within the range of the maximum
number of refresh points.
• Set the refresh range so that it does
not cross over the boundary between
the internal user device and the
extended data register (D) or
extended link register (W).
