Error details
• The write step is illegal.
• The program differs from that stored in the
CPU module.
A block No. outside the range was specified.
A number of blocks that exceeds the range was
specified.
A step No. that is outside the range was
specified.
Step range limit exceeded
The specified sequence step No. is outside the
range.
The specified device is outside the range.
The block specification pattern and step
specification pattern were wrong.
The drive (memory) specified in SFC file
operation is wrong.
The SFC program specified in SFC file operation
does not exist.
The program specified in SFC file operation is
not an SFC program.
Using online program change of SFC, an attempt
was made to execute rewrite operation of the
"SFC dedicated instruction", such as the "STEP
start instruction or transition start instruction",
that shows an SFC chart. (SFC dedicated
instruction cannot be written during RUN.)
Active blocks cannot be changed or deleted.
The number of SFC steps after the program
modification exceeds the maximum number.
The specified block does not exist.
The online change cannot be executed for the
standby type SFC program.
The device number of the SFC data device is
outside the range.
The modified SFC program is incorrect.
Corrective action
• Write the program after setting the CPU module
to the STOP status.
• The starting position of online program change
is not specified with the correct program step
No. Check whether the programming 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 programming tool, and
then execute online change again.
Check the setting contents and make a correction.
Check the number of settings and make a
correction.
Check the setting contents and make a correction.
Check the number of settings and make a
correction.
Check the setting contents and make a correction.
Check the number of settings and make a
correction.
Check the setting contents and make a correction.
Check the setting contents and make a correction.
Check the specified file name and make a
correction.
Check the specified file name and make a
correction.
Switch the CPU module to the STOP status, and
write the program.
After inactivating the target block, change or delete
the block by executing the online change.
Reduce the number of SFC steps to be added by
executing the online change.
• Execute the verify with PLC function for the
unedited SFC program and the SFC program in
the CPU module to check for the consistency.
Then edit the SFC program and execute the
online change.
• Edit the SFC program read from the CPU
module by executing the read from PLC
function, and execute the online change.
Execute the online change (SFC inactive block) for
the scan type SFC program.
Review the block data setting.
Review the communication route (such as the
cable connection status).
