POINT
In the actually mounted CPU No.1, an error may occur due to either of the
following error factors (1) or (2).
(1) When CPU modules exceeding the preset number of CPUs are mounted
(a) When CPU No.1 is a C Controller module
An intelligent function module assignment error (error code: 2126,
SP.UNIT LAY ERROR.) or a parameter error (error code: 3010,
PARAMETER ERROR) occurs.
(b) When CPU No.1 is a Basic model QCPU
A CPU LAY ERROR (error code: 7030) occurs.
(c) When CPU No.1 is a High Performance model QCPU
A PARAMETER ERROR (error code: 3010) occurs.
(2) When any of the preset CPU module mounting slots is open
(a) When CPU No.1 is a C Controller module
An intelligent function module assignment error (error code: 2126,
SP.UNIT LAY ERROR.) or a parameter error (error code: 3010,
PARAMETER ERROR) occurs.
(b) When CPU No.1 is a Basic model QCPU
A CPU LAY ERROR (error code: 7031) occurs.
(c) When CPU No.1 is a High Performance model QCPU
A PARAMETER ERROR (error code: 3010) occurs.
The error that has occurred in the C Controller module can be confirmed on any of
the following screens of the C Controller setting utility.
• <<Module information>> tab ( Section 9.2.2)
• <<Event history>> tab ( Section 9.2.3)
• "System information" screen of <<Module monitor>> tab
