• 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.
• The unsupported module is mounted.
When the unsupported module is
mounted, remove it.
When the corresponding module is
supported, this suggests the intelligent
function module/special function
module, CPU module and/or base unit
is expecting a hardware fault (Contact
your local Mitsubishi representative.)
QCPU
Rem
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.)
The CPU module, base unit and/or the
special function module that was
accessed is experiencing a hardware
fault. (Contact your local Mitsubishi
representative.)
QnA
1402
The intelligent function module/special
function module was accessed in the
program, but there was no response.
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.)
QCPU
Rem
The special function module was
accessed during the execution of a
FROM/TO instruction set, but there was
no response.
(When an error is generated, the
program error location corresponding to
the individual information is stored.)
The CPU module, base unit and/or the
special function module that was
accessed is experiencing a hardware
fault.(Contact your local Mitsubishi
representative.)
