Appendix 1 Error Codes
3430H Operation error • An instruction has been executed
without setting parameters which
are required when the instruction
is executed.
Stop/
continue
• Set parameters required to execute the
instruction.

information
At instruction
execution
3440H Operation error • In a multiple CPU system, the
multiple CPU dedicated
instruction (the one whose symbol
starts with D(P)) was executed
when "Do Not Use" was set to
"Fixed scan communication
function" in the system
parameters ("Multiple CPU
Setting").
Stop/
continue
• Change "Fixed scan communication
function" to "Use".
• Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and change the multiple
CPU dedicated instruction to the one
whose symbol starts with M(P).

At instruction
execution
3441H Operation error • In a multiple CPU system, the
number of data points was
specified exceeding the multiple
CPU dedicated instruction areas
applicable for each CPU module.
Stop/
continue
• Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and change the number
of data points for the multiple CPU
dedicated instruction.

execution
34A0H Operation error • Response data of the socket
communications instruction
cannot be created.
Stop/
continue
• Increase the request interval.
• Decrease the number of request
nodes.
• Wait for a response to the previous
request before sending the next
request.
• Correct the timeout value.

3600H Safety system
configuration
error
■SIL2 Process CPU, SIL2 function
module
• The SIL2 function module
controlled by the host CPU
module is not mounted to the right
of the CPU module.
• The slot right of the CPU module
is set as "Empty" in the system
parameters (I/O Assignment
Setting).
■Safety CPU, safety function
module
• The safety function module
controlled by the host CPU
module is not mounted to the right
of the Safety CPU.
• The slot right of the Safety CPU is
set as "Empty" in the system
parameters (I/O Assignment
Setting).
Stop ■SIL2 Process CPU, SIL2 function
module
• Mount the SIL2 function module
controlled by the host CPU module to
the right of the CPU module.
• Re-set the system parameters (I/O
Assignment Setting) so that the SIL2
function module is right of the CPU
module. If the same error code is
displayed again, the possible cause is
a hardware failure of the CPU module,
the SIL2 function module, or the base
unit. Please consult your local
Mitsubishi representative.

Safety CPU, safety function module
•
Mount the safety function module
controlled by the host CPU module to
the right of the Safety CPU.
• Re-set the system parameter I/O
assignment settings so that there is a
safety function module to the right of
the Safety CPU. If the same error code
is displayed again, the possible cause
is a hardware failure of the Safety
CPU, safety function module, or base
unit. Please consult your local
Mitsubishi representative.
