Error
Error and cause
code
[LINK PARA. ERROR]
• The number of modules actually mounted is
different from that is set in Network parameter
for MELSECNET/H.
• The start I/O number of actually installed
modules is different from that designated in the
network parameter of MELSECNET/H.
• Parameter-set data cannot be used.
• The network type of MELSECNET/H is
overwritten during power-on. (When changing
the network type, switch RESET to RUN.)
• The mode switch of MELSECNET/H module is
outside the range.
3100 ■Collateral information
• Common information: File name/Drive name
• Individual information: Parameter number
■Diagnostic timing
• At power-on/At reset/STOP  RUN
[LINK PARA. ERROR]
A CC-Link IE module with a version that does not
support items set in the network parameter is
mounted/connected.
■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 link refresh range exceeded the file register
capacity.
■Collateral information
• Common information: File name/Drive name
• Individual information: Parameter number
■Diagnostic timing
• When an END instruction or a COM instruction
executed
[LINK PARA. ERROR]
• When the station number of the MELSECNET/H
module is 0, the PLC-to-PLC network parameter
has been set.
• When the station number of the MELSECNET/H
3101
module is other than 0, the remote master
parameter setting has been made.
■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 refresh parameter for the CC-Link IE module
is outside the range.
■Collateral information
• Common information: File name/Drive name
• Individual information: Parameter number
■Diagnostic timing
• At power-on/At reset/STOP  RUN
Corrective action
• 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.
• Set the mode switch of MELSECNET/H
module within the range.
If an error occurs even after taking the above
measures, the cause is a hardware failure.
Please consult your local Mitsubishi
representative.
• Read the individual information of the error
using the programming tool to identify the
numeric value (parameter No.). Check the
parameters corresponding to the value,
and correct them as necessary.
• Mount/connect a CC-Link IE module with a
version that supports items set in the
network parameter.
• Change the file register file for the one that
the entire target range can be refreshed.
• Increase the capacity of the file register, or
reduce the link refresh range.
Correct the type or station number of the
MELSECNET/H module in the network
parameter to meet the used system.
Set the refresh parameter within the range of
device setting.
