44 441 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. Execute I/O assignment again using
parameters from the peripheral device
according to the loading status of special
function modules.
442 There are 9 or more special function
modules (except the interrupt module)
which can execute interruption to the
CPU module loaded. Reduce the special function modules
(except the interrupt module) which can
execute interrupt start to 8 or less.
443 There are 3 or more data link modules
loaded. Reduce the data link modules to 2 or
less.
444 There are 7 or more modules such as a
computer link module loaded to one
CPU module. Reduce the computer link modules to 6
or less.
445 There are 2 or more interrupt modules
loaded. Reduce the interrupt modules to 1.
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. Perform again module assignment for
MNT/MINI automatic refresh with
parameters according to actually linked
station modules.
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.)

448 (1) Five or more network modules have
been installed.
(2) A total of five or more of network
modules and data link modules have
been installed.
(1) Reduce the number to four or less.
(2) Reduce the total number to four or
less.
449 An invalid base module is used.
Failure of base module hardware. Use an available base module.
Replace the failed base module.

46 461 Stop or
Continue
(set by
parameter)
Module specified by the /
instruction is not a special function
module.
Read the error step using a peripheral
device and check and correct contents of
the
/ instruction of the step.
462 (1) Module specified by the dedicated
instruction for special function
module is not a special function
module or not a corresponding
special function module.
(2) A command was issued to a CC-Link
module with function version under
B.
(3) A CC-Link dedicated command was
issued to a CC-Link module for
which the network parameters have
not been set.
(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.
