Code States
(D9092)
— Stop or (1) The fuse is blown in some output
Continue modules.
(set by (2) The external power supply for the
parameter) output load is turned off or it is
disconnected.
— Stop The
FROM
be executed.
(1) Error of control bus with special
function module.
— Stop There is no reply from the special
function module during execution of the
FROM
(1) The special function module being
accessed is faulty.
— Stop Interrupt occurs though no interrupt
module is installed.
— Stop (1) Three or more computer link
modules are installed for a single
CPU module.
(2) Two or more MELSECNET (II),
MELSECNET /B or MELSECNET /
10 data link modules are installed.
(3) Two or more interrupt modules are
installed.
(4) A special function module is
installed to a slot assigned to the I/O
module with parameter setup of the
peripheral device, or vice versa.
(5) The I/O module or special function
module is installed outside the
following I/O number ranges, or
GOT is connected to the bus.
A1SH, A1SJHCPU: X0 to XFF
A2SHCPU(S1): X0 to X1FF
— Stop or (1) Access (execution of
Continue instruction) has been made to a
(set by location where no special function
parameter) module is installed.
462 (1) There is inconsistency in the module
name between the special
instruction for CC-Link and I/O
assignment of the parameter.
(2) The location designated by the
special instruction for CC-Link is not
the master module.

Corrective Action
(1) Check the ERR LED of the output
module. Replace the module with
the lit LED.
(2) Among special registers D9100 to
D9107, the bit corresponding to the
unit of fuse break is "1" .
Replace the fuse of a corresponding
module.
Monitor and check it.
(3) Check ON/OFF of the external
power supply for the output load.
The hardware of the special function
module, CPU module or base unit is
faulty. Replace the faulty module and
check the faulty module. Consult
Mitsubishi representative.
The hardware of the special function
module being accessed is faulty.
Consult Mitsubishi representative.
The hardware of a module is faulty.
Replace the module and check the
faulty module. Consult Mitsubishi
representative.
(1) Reduce the number of computer link
modules to within two.
(2) Reduce the number of MELSECNET
(II), MELSECNET /B and
MELSECNET /10 data link modules
to one.
(3) Reduce the number of interrupt
modules to one.
(4) Using the peripheral device, correct
the parameter I/O assignment
according to the actual state of
installation of the special function
modules.
(5) Examine the I/O number and remove
the modules and GOT installed
outside the range specified on the
left.
(1) Use the peripheral device to read
and correct the and/or
FROM
instruction at the error step.
(1) Correct the module name of I/O
assignment of the parameter to that
of the special instruction for CC-Link.
(2) Use the peripheral device to check
and correct the special instruction for
CC-Link at the error step.
