(D9092)
Stop (1) Three or more computer link
modules are installed for a single
(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
setup
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
(1) Access (execution of FROM or
Stop
or TO instruction) has been made
Contin
to a location where no special
ue
function module is installed.
(set by
462 (1) There is inconsistency in the
para-
module name between the
meter)
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.
Stop (1) There is inconsistency for some
or reason between the data, which
Contin is written by the peripheral
ue device in the parameter area of

of the peripheral device,
MELSEC-A
Corrective Action
(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 FROM and/or
TO 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.
(1) Write parameters and check
again.
(2) If the error persists, there is a
fault in hardware. Consult
Mitsubishi representative.
