[LINK PARA. ERROR]
• Although the CC-Link IE controller network mod-
ule is mounted, network parameter for the CC-
Link IE controller network module is not set.
• Although the CC-Link IE controller network and
MELSECNET/H modules are mounted, network
parameter for the MELSECNET/H module is not
set.

[LINK PARA. ERROR]
In a multiple CPU system, the MELSECNET/H
under control of another CPU is specified as the
head I/O number in the network setting parameter
of the MELSECNET/H.

The network parameter of the MELSECNET/H
operating as the normal station is overwritten to the
control station.

Or, the network parameter of the MELSECNET/H
operating as the control station is overwritten to the
normal station. (The network parameter is updated
on the module by resetting.)

[LINK PARA. ERROR]
• The number of modules actually mounted is dif-
ferent from that is set in Network parameter for
MELSECNET/H.
• The head I/O number of actually installed mod-
ules is different from that designated in the net-
work parameter of MELSECNET/H.
• Some data in the parameters cannot be handled.
• The network type of MELSECNET/H is overwrit-
ten during power-on. (When changing the net-
work type, switch RESET to RUN.)
• The mode switch of MELSECNET/H module
outside the range.

*1 The function version is B or later.
*5 The module whose first 5 digits of serial No. is "07032" or later.
*7 The module whose first 5 digits of serial No. is "09012" or later.
*9 The module whose first 5 digits of serial No. is "10042" or later.
*10 The Universal model QCPU except the Q00UJCPU.
Corrective Action
• Check the network parameter and actual mount-
ing status, and if they differ, make them matched.
When network parameters are modified, write
them to the CPU module.
• Check the setting of extension base unit stage
number.
• Check the connection status of extension base
unit and extension cable. When the GOT is bus-
connected to the main base unit or extension
base unit, also check its connection status.
If an error occurs even after performing the
above checks, the hardware may be faulty.
(Contact your local Mitsubishi representative,
RUN
explaining a detailed description of the problem.)
• Delete the MELSECNET/H network parameter of
the MELSECNET/H under control of another
CPU.
• Change the setting to the head I/O number of the
MELSECNET/H under control of the host CPU.
RUN
Reset the CPU module.
RUN
• Check the network parameters and actual
mounting status, and if they differ, make them
matched.
If any network parameter has been corrected,
write it to the CPU module.
• Check the extension base unit stage No. setting.
• Check the connection status of the extension
base units and extension cables.
When the GOT is bus-connected to the main
base unit and extension base units, also check
the connection status.

If the error occurs after the above checks, the pos-
sible cause is a hardware fault. (Contact your local
Mitsubishi representative, explaining a detailed
description of the problem.)
• Set the mode switch of MELSECNET/H module
within the range.
