Error details and cause
On the multiple CPU synchronous startup
setting, the CPU module that is not
supported the multiple CPU synchronous
startup was set as the target of synchronous
startup.
In the multiple CPU system, a CC-Link IE
Controller Network module controlled by
another CPU is assigned to the start I/O No.
in the CC-Link IE Controller Network
parameter setting.
A network parameter of a CC-Link IE
Controller Network module acting as a
normal station was changed to Control
station. Or a network parameter of a CC-
Link IE Controller Network module acting as
a control station was changed to Normal
station. (Network parameters are reflected
to the module by resetting.)
• The number of modules specified with
the CC-Link IE Controller Network
parameter does not match the number of
modules actually mounted.
• The start I/O No. specified with the CC-
Link IE Controller Network parameter is
different from the actual I/O No.
• Invalid data are included in the
parameters.
• The network type of the CC-Link IE
Controller Network was changed.
• (To change the network type, the status
must be changed from RESET to RUN.)
• A CC-Link IE Controller Network module
is assigned to the start I/O No. in the
MELSECNET/H network parameter
setting.
• A MELSECNET/H module is assigned to
the start I/O No. in the CC-Link IE
controller network parameter setting.
• No CC-Link IE Controller Network
parameters are set even though a CC-
Link IE Controller Network module is
mounted.
• No MELSECNET/H network parameters
are set even though CC-Link IE controller
network module(s) and MELSECNET/H
module(s) are mounted.
The network parameters were written to a
drive different from a valid one.
In the multiple CPU system, a
MELSECNET/H module controlled by
another CPU is assigned to the start I/O No.
in the MELSECNET/H network parameter
setting.
A link parameter of a MELSECNET/H
module acting as a normal station was
changed to Control station. Or a link
parameter of a MELSECNET/H module
acting as a control station was changed to
Normal station. (Link parameters are
reflected to the module by resetting.)
• The number of modules specified with
the MELSECNET/H parameter does not
match the number of modules actually
mounted.
• The start I/O No. specified with the
MELSECNET/H parameter is different
from the actual I/O No.
• Invalid data are included in the
parameters.
• The station type of the MELSECNET/H
was changed while power is on. (To
change the station type, the status must
be changed from RESET to RUN.)
APPENDICES
Corrective action
Remove the CPU from the multiple CPU
synchronized boot-up setting, and correct
the setting.
• Delete the network parameters for the
CC-Link IE Controller Network module
controlled by another CPU.
• Change the setting to the start I/O No. of
the CC-Link IE Controller Network
module controlled by the host CPU.
Reset the CPU module.
• Check the network parameters and the
actual mounting status, and if any
difference is identified, make them
matched. If a network parameter is
corrected, it must be written to the CPU
module.
• Check the setting for the number of
extension base units.
• Check the connected conditions of the
extension base unit(s) and extension
cables. If a GOT is connected to the
main or extension base unit in the bus
topology, also check the connection
status.
If the error occurs even after the above
checks, check the modules and replace a
faulty module.
Write the network parameters to a valid
drive.
• Delete the MELSECNET/H network
parameter for the MELSECNET/H
module controlled by another CPU.
• Change the setting to the start I/O No. of
the MELSECNET/H module controlled
by the host CPU.
Reset the CPU module.
• Check the network parameters and the
actual mounting status, and if any
difference is identified, make them
matched. If a network parameter is
corrected, it must be written to the CPU
module.
• Check the setting for the number of
extension base units.
• Check the connected conditions of the
extension base unit(s) and extension
cables. If a GOT is connected to the
main or extension base unit in the bus
topology, also check the connection
status.
If the error occurs even after the above
checks, check the modules and replace a
faulty module.
