(2) When programmable controller CPU version incompatible with C
Controller module is used
When a multiple CPU system including the C Controller module is configured by using
a programmable controller CPU version incompatible with C Controller module, the
following error occurs and the multiple CPU system does not start up.
(a) When CPU No. 1 is Basic model QCPU
1) Error check method
If an error has occurred, check the error details in the PLC diagnostics of GX
Developer Version 8 or later.
2) Corrective action for error occurrence
If the error indicated in Table12.11 is displayed, replace the Basic model
QCPU of function version B whose first five digits of serial No. are "06111" or
earlier with the Basic model QCPU of function version B whose first five digits
of serial No. are "06112" or later.
* 1 MULTI CPU DOWN indicates a multi CPU error.
