Error
Code Error Contents and Cause
*1
(SD0)
An interruption has occurred although
1310
there is no interrupt module.
An interrupt request from other than
the interrupt module was detected.
1311 An interrupt request from the module
where interrupt pointer setting has not
been made in the PLC parameter
dialog box was detected.
• There was no response from the
intelligent function module/special
function module in the initial
processing.
• The size of the buffer memory of the
intelligent function module/special
function module is invalid.
1401
When PLC parameter I/O allocation
was being made, there was no return
signal from the special function
module during initial processing
stage.(When error is generated, the
head I/O number of the special
function module that corresponds to
the common information is stored.)
*1 Characters in parentheses ( ) indicate the special register numbers where individual information is being
:
stored.
*12 This applies to the CPU module of function version B or later.
:
*13 This applies to the CPU module of function version A.

Corrective Action
Any of the mounted modules is
experiencing a hardware fault.
Therefore, check the mounted
modules and change the faulty
module. (Contact your local Mitsubishi
representative.)
Take action so that an interrupt will not
be issued from other than the interrupt
module.
• Correct the interrupt pointer setting
in the PLC system setting of the
PLC parameter dialog box.
• Take measures so that an interrupt
is not issued from the module where
the interrupt pointer setting in the
PLC system setting of the PLC
parameter dialog box has not been
made.Correct the interrupt setting of
the network parameter.Correct the
interrupt setting of the intelligent
function module buffer
memory.Correct the basic program
of the QD51.
This suggests the intelligient function
module/special function module , CPU
module and/or base unit is expecting a
hardware fault (Contact your local
Mitsubishi representative.)
The CPU module, base unit and/or the
special function module that was
accessed is experiencing a hardware
fault.(Contact your local Mitsubishi
representative.)
