[PARAMETER ERROR]
The system file that have stored the remote
password setting information is damaged.
■Collateral information
3042
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[LINK PARA. ERROR]
In a multiple CPU system, the CC-Link IE module
controlled by another CPU is specified as the head
I/O number of the CC-Link IE module.
■Collateral information
• Common information: File name/Drive name
• Individual information: Parameter number
■Diagnostic Timing
• At power-on/At reset/STOP→RUN
[LINK PARA. ERROR]
The network parameter of the CC-Link IE
operating as the normal station is overwritten to
the control station. Alternatively, the network
parameter for the CC-Link IE module that is
operating as a normal station has been changed to
the control station. (The network parameter is
updated on the module by resetting.)
■Collateral information
• Common information: File name/Drive name
3100
• Individual information: Parameter number
■Diagnostic Timing
• At power-on/At reset/STOP→RUN
[LINK PARA. ERROR]
• The number of modules actually mounted is
different from that is set in Network parameter
for the CC-Link IE module.
• The head I/O number of the actually mounted
module is different from the one set in the
network parameter of the CC-Link IE.
• Parameter-set data cannot be used.
• The network type of CC-Link IE is overwritten
during power-on. (When changing the network
type, switch RESET to RUN.)
■Collateral information
• Common information: File name/Drive name
• Individual information: Parameter number
■Diagnostic Timing
• At power-on/At reset/STOP→RUN

Corrective Action
• Write the parameters configured in the PLC
parameter and Network parameter dialog
boxes and remote password to a parameter-
valid drive, and power on the system again or
reset the CPU module.
If the same error occurs, the cause is a
hardware failure. (Please consult your local
Mitsubishi representative, explaining a detailed
description of the problem.)
• When a valid drive for parameter is set to other
than [program memory], set the parameter file
(PARAM) at the boot file setting to be able to
transmit to the program memory.
Write the PLC parameter, network parameter,
and remote password to a parameter-valid
drive, and power on the system again or reset
the CPU module.
If the same error occurs, the cause is a
hardware failure. (Please consult your local
Mitsubishi representative, explaining a detailed
description of the problem.)
• Delete the network parameter of the CC-Link IE
module controlled by another CPU.
• Change the setting to the head I/O number of
the CC-Link IE module controlled by host CPU.
Reset the CPU module.
• Check the network parameters and actual
mounting status, and if they differ, make them
matched. If any of the network parameters is
corrected, write it to the CPU module.
• Check the set number of extension base units.
• Check the connection status of the extension
base units and extension cables.
Check the connection of the GOT if it is bus-
connected to the main base unit or extension
base unit.
If an error occurs even after taking the above
measures, the cause is a hardware failure.
(Please consult your local Mitsubishi
representative, explaining a detailed description
of the problem.)
