PARAMETERS ADDED FOR MULTIPLE CPU SYSTEM
If some of the Multiple CPU setting parameters have been changed, adjust the all CPU
settings in the multiple CPU system to the same values, and then reset CPU No.1, or
reboot the multiple CPU system (power ON, OFF, and ON again).
The C Controller setting utility has a feature that allows you to utilize multiple CPU
parameters previously set on GX Developer. ( Section 17.2.4)
(3) Multiple CPU parameter checking
When the multiple CPU system is powered on or CPU No.1 is reset, whether the
same multiple CPU parameters are set to all CPU modules or not is checked
(consistency check between CPUs) as described in Table15.2 for the items marked
and
in the Same setting column in Table15.1.
(a) When settings of all CPUs are identical
The multiple CPU system starts up.
(b) When settings of all CPUs are not identical
The multiple CPU system behaves as shown in Table15.2.
Check the multiple CPU parameters, and make sure that those of all CPUs are
identical.
To start up the multiple CPU system, reset CPU No.1, or reboot the multiple CPU
system (power ON, OFF, and ON again).
Refer to Section 13.6 for the operation after resetting CPU No.1.
Table15.2 List of whether consistency check between CPUs is executed or not
Item CPU No.1 Other than CPU No.1
When multiple CPU system is powered on
No consistency check between CPU
modules for the multiple CPU
parameters will be run.
• The multiple CPU parameters are
compared with those of CPU No.1.
• If any mismatch is found, a
parameter error (error code: 3012,
PARAMETER ERROR) occurs in the
CPU.
