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.)

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.

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 or less.
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.
Make the total of the installed network
modules and data link modules four or
less.
