36.4 List of Error Codes
Error details and cause
• The capacity of label area used exceeded its
limit.
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".
• The target CPU module does not support
"Access from External Device" of "Global Label
Setting".
• The specified program execution type is not
supported.
• A second SFC program has been started while
an SFC program was running.
• An SFC program is stopped while "Stop Mode" is
set to "Hold output after stop".
• A program has started or stopped while the CPU
module is in the STOP or PAUSE state.
• A control system execution program has started
or stopped in CPU module of the standby system
when the redundant system is in backup mode.
• An SFC program has started or stopped when
the operation mode of the CPU module is
redundant mode.
• 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.
• 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.
• Access to the specified station cannot be made.
• A request for network test was issued.
• 121 stations or more are specified to the station
number.
• The number of files in the specified folder
exceeded the limit.
Action
• 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.
• 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".
• Disable "Access from External Device", and then write the
data to the programmable controller again.
• Check the program execution type specified.
• Check the execution status of the SFC program.
• Set "Stop Mode" to "Stop output after stop".
• Set the CPU module to the RUN state and execute the
program again.
• Execute the program in the CPU module of the control
system.
• Check the name of the program specified.
• Check the name of the program specified.
• 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.
• Check and correct the routing parameters set to the related
stations.
• Set communication through the network that is supported by
the specified CPU module.
• 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.
• Check the request of the SLMP/MC protocol.
• Check the station number.
• Reduce the number of files in the specified folder.
