36 ERROR CODES
36.4 List of Error Codes
4905H Any other error • The capacity of label area used exceeded its
limit.
• Check the program, delete the unused local and global label
definitions, compile the program, and then write the program
to the programmable controller.
• Change the label area size in parameter, compile the
program, and then write the program to the programmable
controller.
4906H Any other error The file register data cannot be cleared by either of
the following reasons:
• The QDRSET instruction was executed more
than once after the CPU module was powered on
or reset.
• The file register setting parameter is set to the
one other than "Use Common File Register in All
Programs".
• If the QDRSET instruction is being executed, power on or
reset the CPU module.
• The operation cannot be performed if the file register setting
parameter is not set to "Use Common File Register in All
Programs".
4907H Any other error • The target CPU module does not support
"Access from External Device" of "Global Label
Setting".
• Disable "Access from External Device", and then write the
data to the programmable controller again.
4908H Any other error • The specified program execution type is not
supported.
• Check the program execution type specified.
4909H Any other error • A second SFC program has been started while
an SFC program was running.
• Check the execution status of the SFC program.
490AH Any other error • An SFC program is stopped while "Stop Mode" is
set to "Hold output after stop".
• Set "Stop Mode" to "Stop output after stop".
490BH Any other error • A program has started or stopped while the CPU
module is in the STOP or PAUSE state.
• Set the CPU module to the RUN state and execute the
program again.
490CH Any other error • A control system execution program has started
or stopped in CPU module of the standby system
when the redundant system is in backup mode.
• Execute the program in the CPU module of the control
system.
• Check the name of the program specified.
490DH Any other error • An SFC program has started or stopped when
the operation mode of the CPU module is
redundant mode.
• Check the name of the program specified.
4A00H Network error • Access to the specified station cannot be made
since the routing parameters, network number/
station, or network station <-> IP-related
information setting are not set to the start source
CPU module and/or relay CPU module.
• For routing via a multiple CPU system, the
control CPU module of the network module for
data routing or the CPU module for data routing
has not started.
• The third byte of the IP address (network
number) specified for the IP communication test
is the same as that of the CPU module where the
test is executed.
• The CPU module that performs IP packet
transfer is not the control CPU of the CC-Link IE
module, which is on the path that IP packets
travel.
• Set the routing parameters, network number/station, or
network station <-> IP-related information setting for
accessing the specified station to the related stations.
• Retry after a while. Or, start communication after checking
that the system for data routing has started.
• Do not use the same third byte of the IP address (network
number) specified for the IP communication test with that of
the CPU module where the test is executed.
• Set the CPU module that performs IP packet transfer as the
control CPU of the CC-Link IE module, which is on the path
that IP packets travel.
4A01H Network error • The network of the number set to the routing
parameters does not exist.
• The specified CPU module cannot be
communicated through the network that is not
supported by the CPU module.
• Check and correct the routing parameters set to the related
stations.
• Set communication through the network that is supported by
the specified CPU module.
4A02H Network error • Access to the specified station cannot be made. • Check the network module for error, or check that the
modules are not in offline.
• Check if the network numbers/PC numbers are correctly set.
4A03H Network error • A request for network test was issued. • Check the request of the SLMP/MC protocol.
4A05H Link related error (file
related error)
• 121 stations or more are specified to the station
number.
• Check the station number.
4A10H Link related error (file
related error)
• The number of files in the specified folder
exceeded the limit.
• Reduce the number of files in the specified folder.
