Error Error name Error details and cause
code
3205H Program • After the global label setting file was
execution error modified, only the modified file was
written. Or, without writing the global
label setting file, only the program
file(s) and FB file(s) were written.
• After an FB file was modified, only the
modified file was written. Or, without
writing the modified FB file, only the
program file(s) and global label
setting file were written.
• After the "Access from External
Device" setting of the global label
setting was changed, only the global
label assignment information was
written. Or, after the "Access from
External Device" setting was
changed, only the sequence program
file(s) and FB file(s) were written.
• When the "Access from External
Device" setting is not selected, the
sequence program file(s), FB file(s),
and global label setting file are written
without initializing the memory where
the global label assignment
information file is stored.
• The global label assignment
information that does not correspond
to the firmware version of the CPU
module was written due to memory
copy or restoration.
3206H Program • After the sequence program was
execution error modified, only the modified sequence
program file was written to the
programmable controller. Or, without
writing the modified sequence
program file, only the initial local label
value file was written to the
programmable controller.
• After the global label setting file was
modified, only the modified file was
written to the programmable
controller. Or, without writing the
modified global label setting file, only
the initial global label value file was
written.
3207H Program • The signal flow area to be used in the
execution error FB program cannot be secured.
3220H SFC program • Unable to execute the SFC program.

Stop • Write all the sequence program
file(s), FB file(s), global label
setting file, and global label
assignment information file to the
programmable controller.
• If no global label is used, delete
the global label setting file.
• If the "Access from External
Device" setting is not selected,
initialize the memory where the
global label assignment
information file is stored, and write
the sequence program file(s), FB
file(s), and global label setting file
to the programmable controller.
Stop • Write both the sequence program
file(s) and initial local label value
file to the programmable
controller.
• Write both the global label setting
file and initial global label value file
to the programmable controller.
• If no initial global label value is
used, delete the initial global label
value file.
• If no initial local label value is
used, delete the initial local label
value file.
Stop • Check the detailed information
(drive/file information) of the error
by executing module diagnostics
using the engineering tool, and
identify the error program file.
Then, reduce the number of
instructions that use the signal
flow area of the FB program used
in the sequence program file.
Stop • Take measures to reduce noise.
• Write the SFC program and CPU
parameters to the CPU module
again. Then, reset the CPU
module and run it again. If the
same error code is displayed
again, the possible cause is a
hardware failure of the CPU
module. Please consult your local
Mitsubishi representative.
