441 STOP A special function module is assigned
as an I/O module, or vice versa, in the I/
O assignment using parameters from
the peripheral device.
442 There are 9 or more special function
modules (except the interrupt module)
which can execute interruption to the
CPU module loaded.
443 There are 2 or more data link modules
loaded.
444 There are 7 or more modules such as a
computer link module loaded to one
CPU module.
445 There are 2 or more interrupt modules
loaded.
446 Modules assigned by parameters for
MNT/MINI automatic refresh from the
peripheral device do not conform with
the types of station modules actually
linked.
447 The number of modules of I/O
assignment registration (number of
loaded modules) per one CPU module
for the special function modules which
can use dedicated instructions is larger
than the specified limit. (Total of the
number of computers shown below is
larger than 1344.)

Corrective Action
Execute I/O assignment again using
parameters from the peripheral device
according to the loading status of special
function modules.
Reduce the special function modules
(except the interrupt module) which can
execute interrupt start to 8 or less.
Reduce the data link modules to 1 or
less.
Reduce the computer link modules to 6
or less.
Reduce the interrupt modules to 1.
Perform again module assignment for
MNT/MINI automatic refresh with
parameters according to actually linked
station modules.
Reduce the number of loaded special
function modules.
*Available when the extension mode is
used.

(1) Reduce the number to four or less.
(2) Reduce the total number to four or
less.
Use an available unit module.
Replace the failed unit module.
Read the error step using a peripheral
device and check and correct contents of
the / instruction of the step.
FROM TO
(1) Read the error step using a peripheral
device and check and correct
contents of the dedicated instruction
for special function modules of the
step.
(2) Replace with a CC-Link module
having function version B and above.
(3) Set the parameters.
