(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.
