Error details and cause
• The write step is illegal.
• The program differs from that stored in the CPU
module.
• A block No. outside the range was specified.
• The number of blocks exceeds the range.
• A step No. outside the range was specified.
• The number of steps exceeds the range.
• A sequence step No. outside the range was
specified.
• The specified device is outside the range.
• The block specification pattern and step
specification pattern are incorrect.
• A block No. that does not exist in the 0 to 319
range was specified.
• A step No. that does not exist in the 0 to 511
range was specified.
• The drive (memory) specified with the SFC
program file operation is incorrect.
• The SFC program specified with the SFC
program file operation does not exist.
• The program specified with the SFC program file
operation is not an SFC program.
• An attempt was made to rewrite a dedicated SFC
instruction by changing an SFC program online.
• An attempt was made to change or delete the
active block.
• The number of SFC steps after the program
change exceeded the maximum.
• The specified block does not exist.
• The online change cannot be executed to the
standby type SFC program.
• The device number of SFC information device is
outside the range.
• The changed SFC program is incorrect.
• The online change for each block cannot be
executed to the SFC block whose number of
sequential steps exceeds 32K steps.
• The online change cannot be executed because
writing to the programmable controller in the
STOP state has just completed or a program
execution error has occurred.
Action
• Set the operating status of the CPU module to STOP, and
write the program.
• The starting position of online program change is not
specified with the correct program step number. Check
whether the engineering tool supports the model and version
of the CPU module that is specified for the project.
• Read the program from the CPU module to match it with that
of the engineering tool, and then execute the online program
change again.
• Check the setting and correct it.
• Check the set quantity and correct it.
• Check the setting and correct it.
• Check the set quantity and correct it.
• Check the setting and correct it.
• Check the set quantity and correct it.
• Check the setting and correct it.
• Check the setting and correct it.
• Check the setting and correct it.
• Check the setting and correct it.
• Check the specified file name and correct it.
• Check the specified file name and correct it.
• Set the operating status of the CPU module to STOP, and
write the SFC program.
• Inactivate the target block.
• Reduce the number of SFC steps to be added and execute
the online change again.
• Read the program from the CPU module to match it with that
of the engineering tool, and then execute the online program
change again.
• After setting the operating status of the CPU module to
STOP, write the SFC program to the programmable
controller.
• Check and correct the setting of the block information.
• Execute again after checking the communication route such
as the communication cable.
• 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.
• After the operating status of the CPU module is changed
from STOP to RUN, execute the online SFC block change or
the online program change.
• After preventing the program execution error from occurring,
execute the online SFC block change or the online program
change.
