A
3610H Safety system
configuration
error
■SIL2 Process CPU
• The SIL2 function module with a
pair version that differs from the
one of the SIL2 Process CPU is
mounted.
■Safety CPU
• The safety function module with a
pair version that differs from the
one of the Safety CPU is
mounted.
Stop ■SIL2 Process CPU
• Mount the safety function module with
the same pair version as the one of the
SIL2 function module.
■Safety CPU
• Mount the safety function module with
the same pair version as the one of the
Safety CPU.

3620H Control CPU
module error
• An error has been detected in the
control CPU module.
Stop • Reset the Safety CPU, and run it again.
If the same error code is displayed
again, the possible cause is a
hardware failure of the control CPU
module or this module. Please consult
your local Mitsubishi representative.

3621H SIL2 system
configuration
error
• A module with a firmware version
that does not support the safety
functions that are available to the
system using the SIL2 Process
CPU is mounted.
• A module that does not support
the system using the SIL2
Process CPU is mounted.
Stop • Check the firmware version of the
corresponding module. If the module
that does not support the safety
functions that are available to the
system using the SIL2 Process CPU is
mounted, remove the module from the
base unit.
• Check the detailed information (system
configuration information) of the error
by executing module diagnostics using
the engineering tool and check the
module corresponding to the displayed
slot number. If the module does not
support the system using the SIL2
Process CPU, remove the module from
the base unit.

3622H SIL2 system
configuration
error
• The redundant function module is
not mounted to the right of the
SIL2 function module.
• The slot right of the SIL2 function
module is set as "Empty" in the
system parameters (I/O
Assignment Setting).
Stop • Mount the redundant function module
to the right of the SIL2 function module.
• Re-set the system parameters (I/O
Assignment Setting) so that the
redundant function module is right of
the SIL2 function module. If the same
error code is displayed again, the
possible cause is a hardware failure of
the CPU module, the SIL2 function
module, the redundant function
module, or the base unit. Please
consult your local Mitsubishi
representative.

3640H Safety mutual
monitoring error
■SIL2 Process CPU, SIL2 function
module
• A file mismatch has been detected
in the mutual monitoring between
the SIL2 Process CPU and SIL2
function module.
■Safety CPU, safety function
module
•
A file mismatch has been detected
in the mutual monitoring between
the Safety CPU and safety
function module.
Stop • Format the memory. Write all files to
the CPU module. Then, reset the CPU
module and run it again
