40A8H SFC device
specification
error
■R00CPU, R01CPU, R02CPU:
• A step No. that does not exist in the 0 to 127 range was
specified.
■CPU module other than above models:
• A step No. that does not exist in the 0 to 511 range was

40B0H SFC file related
error
• The drive (memory) specified with the SFC program file
operation is incorrect.
• Check the setting and correct it.
40B1H SFC file related
error
• The SFC program specified with the SFC program file
operation does not exist.
• Check the specified file name and correct it.
40B2H SFC file related
error
• The program specified with the SFC program file operation
is not an SFC program.
• Check the specified file name and correct it.
40B3H SFC file related
error
• An attempt was made to rewrite a dedicated SFC instruction
by changing an SFC program online.
• Set the operating status of the CPU module to STOP, and
write the SFC program.
40B4H SFC file related
error
• An attempt was made to change or delete the active block. • Inactivate the target block.
40B5H SFC file related
error
• The number of SFC steps after the program change
exceeded the maximum.
• Reduce the number of SFC steps to be added and execute
the online change again.
40B6H SFC file related
error
• The specified block does not exist. • Read the program from the CPU module to match it with that
of the engineering tool, and then execute the online program
change again.
40B7H SFC file related
error
• The online change cannot be executed to the standby type
SFC program.
• After setting the operating status of the CPU module to
STOP, write the SFC program to the programmable
controller.
40B8H SFC file related
error
• The device number of SFC information device is outside the
range.
• Check and correct the setting of the block information.
40B9H SFC file related
error
• The changed SFC program is incorrect. • Execute again after checking the communication route such
as the communication cable.
40BAH SFC file related
error
• The online change for each block cannot be executed to the
SFC block whose number of sequential steps exceeds 32K
steps.
• To execute the online change for each block, the number of
sequential steps of the target SFC block must be within 32K
steps.
• After setting the operating status of the CPU module to
STOP, write the SFC program to the programmable
controller.
4
0BBH SFC file related
error
• The online change cannot be executed because writing to
the programmable controller has just completed or a
program execution error has occurred.
• After the operating status of the CPU module is changed
from STOP to RUN, execute the online change (SFC block).
• After preventing the program execution error from occurring,
execute the online change (SFC block).
