Error name Error details and cause Corrective action
2000H Module configuration error The module type set in the system parameters (I/O
assignment setting) differs from that of the module
actually mounted.
Re-set the module type in the system parameters in
accordance with the CPU module or intelligent function
module actually mounted.
2001H Module configuration error The I/O numbers set in the system parameters (I/O
assignment setting) are overlapping between modules.
Re-set the I/O numbers in the system parameters in
accordance with the intelligent function module or I/O
module actually mounted.
2002H Module configuration error The number of points assigned to the intelligent function
module in the system parameters (I/O assignment setting)
is smaller than that of the module actually mounted.
Re-set the number of points in the system parameters in
accordance with the intelligent function module actually
mounted.
2006H Module configuration error A module is mounted on the 65th slot or later. Remove the module mounted on the 65th slot or later.
2007H Module configuration error A module is mounted on the slot whose number is later
than that specified in parameter (I/O assignment setting).
Remove the module mounted on the slot whose number is
later than that specified in system parameter (I/O
assignment setting).
2008H Module configuration error A module is mounted over or across the maximum
number of I/O points (4096).
• Remove the module mounted over or across the
maximum number of I/O points (4096).
• Replace the module mounted on the last slot to the one
that does not exceed the maximum number of I/O
points (4096).
2009H Module configuration error There is no response from the I/O module or intelligent
function module accessed.
• Check and correct the I/O assignment setting in the
system parameters.
• The possible cause is a hardware failure of the I/O
module or intelligent function module accessed. Please
consult your local Mitsubishi representative.
2020H Module configuration error An unsupported module is mounted. Remove the unsupported module. If all the modules are
supported, the possible cause is a hardware failure of the
CPU module, base unit, or module (I/O module or
intelligent function module) connected. Please consult
your local Mitsubishi representative.
2021H Module configuration error In the multiple CPU system, the control CPU of the Q
series intelligent function module incompatible with the
multiple CPU system is set to other than CPU No.1.
• Replace the Q series intelligent function module with
the one (function version B) compatible with the multiple
CPU system.
• Set the control CPU of the Q series intelligent function
module incompatible with the multiple CPU system to
CPU No.1.
2040H CPU module configuration
error
• The number of CPU modules set in the system
parameters (I/O assignment setting) differs from the
number of CPU modules actually mounted.
• The CPU module is mounted on the slot different from
the one specified in the system parameters (I/O
assignment setting).
• Correctly set the number of CPU modules (including the
empty setting) in the system parameters in accordance
with the number of CPU modules actually mounted.
• Correctly set the system parameters so that the setting
and actual CPU module mounting status will be the
same.
2041H CPU module configuration
error
• The CPU module is not mounted on the slot that is set
for the CPU module in the system parameters (I/O
assignment setting).
• An I/O module or intelligent function module is mounted
between the CPU modules.
• Correctly set the number of CPU modules (including the
empty setting) in the system parameters in accordance
with the number of CPU modules actually mounted.
• Remove the I/O module or intelligent function module
mounted between the CPU modules.
2043H CPU module configuration
error
The CPU module is mounted on the inapplicable slot. • Mount the CPU module on the applicable slot (CPU slot
or I/O slot 0 to 6).
• Remove the CPU module from the inapplicable slot.
2044H CPU module configuration
error
The host CPU No. set in the system parameters (I/O
assignment setting) differs from the one determined by the
mounting position of the CPU module.
Re-set the host CPU No. in the system parameters in
accordance with the mounting position of the CPU
module.
2050H CPU module configuration
error
An unsupported CPU module is mounted. Remove the unsupported CPU module. If all the CPU
modules are supported, the possible cause is a hardware
failure of the CPU module or base unit. Please consult
your local Mitsubishi representative.
20
60H
Base unit configuration
error
Eight or more extension base units are connected. Reduce the number of extension base units to seven or
less.
