Appendix 3 Error Code
Error details and cause
• The module specified in the I/O
assignment setting of the parameters is
not connected.
• Parameters for a standard input/output
module are set to a high-speed pulse
input/output module.
• The I/O numbers of the reserved module
specified in the I/O assignment setting of
the parameters overlap those of other
modules.
• The I/O method of the input/output
module is different.
• The type of the CPU module is different.
• The model of the module connected is
different from that of the module set in
the parameters.
• The total number of I/O points (excluding
remote I/O) exceeded 256.
• The number of input, output, input/
output, and intelligent function modules
connected is equal to or greater than 17.
• The number of communication adapters
connected is equal to or greater than 3.
• The number of analog adapters
connected is equal to or greater than 5.
• The number of extension power supply
modules connected is equal to or greater
than 3.
• The number of expansion boards
connected is equal to or greater than 2.
• An unsupported module was detected.
• An SD memory card error was detected.
• The SD memory card may have been
removed without the SD memory card
disabled.
• An SD memory card error was detected.
• The SD memory card may not be
correctly formatted.
• The IP address is duplicated within the
system.
• An error was found in the data of the file.
• The file specified in the parameters does
not exist.
Action
• Make sure that the parameters are
consistent with the connections.
• Make sure that the parameters are
consistent with the connections.
• Make sure that the parameters are
consistent with the connections.
• Make sure that the parameters are
consistent with the connections.
• Make sure that the parameters are
consistent with the connections.
• Make sure the model of the module to be set
is consistent with the parameters of the
module connected.
• Do not use more than 256 I/O points in
programs.
• Use up to 16 input, output, input/output, and
intelligent function modules.
• Use up to 2 communication adapters.
• Use up to 4 analog adapters.
• Use up to 2 extension power supply
modules.
• Use up to 1 expansion board.
• Verify that the version of the CPU module is
compatible with the module where the error
was detected.
• If the version of the CPU module is correct,
there may be a malfunction in the connected
module. Replace the connected module.
• Check the connection of the SD memory
card. If the problem persists, there may be a
malfunction in the SD memory card or CPU
module.
• Format the SD memory card. If the problem
persists, there may be a malfunction in the
SD memory card or CPU module.
• Review the setting so that the IP address is
not duplicated within the system.
• Recreate the file.
• Rewrite the project.
