Appendix 1 Error Codes
37C1H
Program
execution error
• In the CPU module which
operates in redundant mode, an
SFC program is set in the CPU
parameters ("Program Setting").
Stop
• Check the detailed information (drive/
file information) of the error by
executing module diagnostics using
the engineering tool, and delete all
SFC programs registered. Then, write
CPU parameters to the CPU module
again.

Memory format
by memory copy
• The memory copy was executed
and the memory in the standby
system has been formatted.
Stop
• Power off and on or reset the CPU
module after the memory copy
completed.

Hardware failure
• A hardware failure has been
detected.

■
CPU module
• Take measures to reduce noise.
• Check the mounting status of the CPU
module, SIL2 function module, and
safety function module.
• 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
or module (SIL2 function module or
safety function module) connected.
Please consult your local Mitsubishi
representative.
■
Redundant function module
• The possible cause is malfunction due
to noise. Take measures to reduce
noise by checking the distance of wires
and cables, and the grounding status of
each device.
• Execute a module communication test.
If the same error code is displayed
again, the possible cause is a
hardware failure of the redundant
function module. Please consult your
local Mitsubishi representative.

• Check the mounting status of the CPU
module, SIL2 function module, and

• 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,
extended SRAM cassette, battery-less
option cassette, or module (SIL2
function module or safety function
module) connected. Please consult
your local Mitsubishi representative.
