36.4 List of Error Codes
Error details and cause
• The specified step exceeds the range
that can be used in the SFC program.
• The number of simultaneous active
block steps that can be specified in
the SFC program exceeds the
permissible value.
• The total number of simultaneous
active steps that can be specified in
the SFC program exceeds the
permissible value.
• A SET Sn/BLm\Sn and RST Sn/
BLm\Sn instruction were specified for
the self step in the step operation
output.
• Memory/Device Setting set in the
CPU parameters differ from those
assigned to the sequence programs,
FB programs, and global label setting
file. (After Memory/Device Setting
were modified, only the CPU
parameters were written to the CPU
module.)
• Even though no program is set in the
CPU parameters, multiple program
files exist.
• The program file is incorrect. Or, the
program file is not written properly.
• For the subroutine type FB, "Use MC/
MCR to Control EN" of "Inherent
Property" is set to "Yes".
• No program file exists.
• Two or more SFC programs were
executed.
Stop/ Action
continue
Stop • Check the detailed information
(error location information) of the
error by executing module
diagnostics using the engineering
tool, display the error program
(step) by clicking the [Error Jump]
button, and correct the program.
• Turn on SM321 (Start/stop SFC
program) if it is off.
Stop • Check the detailed information
(error location information) of the
error by executing module
diagnostics using the engineering
tool, display the error program
(step) by clicking the [Error Jump]
button, and correct the program.
Stop • After Memory/Device Setting are
modified, write the sequence
program file(s), FB file(s), and
global label setting file together
with the CPU parameter file to the
CPU module.
• If no global label is used, delete
the global label setting file.
Stop • Set a program in the CPU
parameter.
• Delete unnecessary program files.
Stop • Write the program file to the CPU
built-in memory again.
• Set "Use MC/MCR in EN Control"
in "Inherent Property" of
subroutine-type FB to "No" and
write the program file to the CPU
built-in memory again.
• Replace the CPU module with the
one that supports the use of the
subroutine-type FB for which "Use
MC/MCR in EN Control" of
"Inherent Property" is set to "Yes".
Stop • Check if the system parameter file,
CPU parameter file, and program
file exist.
• Write the system parameter file,
CPU parameter file, and program
file to the CPU built-in memory.
Stop • Ensure that only one SFC
program is executed.
