Appendix 1 Error Codes
3170H SFC program
block, step error
• The number of SFC program
steps exceeds the total number of
step relays (S).
Stop • Correct the program so that the
number of SFC program steps does
not exceed the total number of step
relays (S).
• Check and correct the number of
device setting step relays (S) in the
CPU parameters.

3171H SFC program
block, step error
• The total number of SFC program
blocks (max. step No. + 1)
exceeds the total number of step
relays (S).
Stop • Correct the program so that the total
number of SFC program blocks (max.
step No. + 1) does not exceed the total
number of step relays (S).
• Check and correct the number of
device setting step relays (S) in the
CPU parameters.

error
• The SFC program configuration is
illegal.
Stop • Take measures to reduce noise.
• Write the SFC program 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.
