Error Error name Error details and cause
code
1B61H Standby A moderate error or major error has
system remote been detected in the remote head
head module module of the standby system. (The
error error is detected in the control system.)
1B70H Communication Data communications cannot be
s with the other performed with the other system. (The
system error is detected in the control system or
disabled the standby system.)
1BD0H System The systems were not switched. There
switching error was a cause of system switching failure.
(The error is detected in the control
system.)
1D10H Inter-module Cyclic transmission skip occurred.

2000H Module The module type set in the system
configuration parameters ("I/O Assignment Setting" in
error the [I/O Assignment] tab of the "System
Parameter" window) differs from that of
the module actually mounted.
2001H Module The I/O numbers set in the system
configuration parameters ("I/O Assignment Setting" in
error the [I/O Assignment] tab of the "System
Parameter" window) are overlapping
between modules.
2002H Module The number of points assigned to the
configuration intelligent function module in the system
error parameters ("I/O Assignment Setting" in
the [I/O Assignment] tab of the "System
Parameter" window) is smaller than that
of the module actually mounted.
2004H Module • CC-Link IE Controller Network
configuration module* or/and CC-Link IE Field
error Network module* are mounted on the
main base unit or extension base unit.
• Nine or more CC-Link master/local
modules are mounted on the main
base unit and extension base unit.
The CC-Link IE built-in Ethernet
interface module is included if the
module is used as a CC-Link IE
Controller Network module or CC-Link
IE Field Network module.
2006H Module A module is mounted on the 65th slot or
configuration later.

Action
Eliminate the error cause, and restart the system.
If the same error code is displayed again, the
possible cause is a hardware failure of the remote
head module. Please consult your local Mitsubishi
representative.
• When the remote head module of the standby
system is in the reset mode, exit the reset mode.
• When the remote head module of the standby
system is not mounted, mount the module.
• Take measures to reduce noise.
• If the same error code is displayed again, the
possible cause is a hardware failure of the
remote head module or base unit. Please
consult your local Mitsubishi representative.
Check the cause of system switching failure in the
detailed information (system switching information)
of the error by executing module diagnostics using
the engineering tool, eliminate the error cause, and
switch the systems from the engineering tool
again. If the same error code is displayed again,
the possible cause is a hardware failure of the
remote head module. Please consult your local
Mitsubishi representative.
• Increase the value set in "Fixed Scan Interval
Setting of Inter-module Synchronization" under
"Inter-module Synchronous Setting" in the [Inter-
module Synchronous Setting] tab of the "System
Parameter" window so that the inter-module
synchronization cycle will not be exceeded.
• Reduce the refresh processing time by reducing
the data targeted for synchronization refreshing
so that the inter-module synchronization cycle
will not be exceeded.
• Set modules not requiring synchronization to
asynchronous so that the inter-module
synchronization cycle will not be exceeded.
Re-set the module type in the system parameters
in accordance with the remote head module or
intelligent function module actually mounted.
Re-set the I/O numbers in the system parameters
in accordance with the intelligent function module
or I/O module actually mounted.
Re-set the number of points in the system
parameters in accordance with the intelligent
function module actually mounted.
• Remove the CC-Link IE Controller Network
module or CC-Link IE Field Network module
which is mounted on the main base unit or
extension base unit.
• Decrease the total number of CC-Link master/
local modules mounted on the main base unit
and extension base unit to eight or less.
* The CC-Link IE built-in Ethernet interface module
is included if the module is used as a CC-Link IE
Controller Network module or CC-Link IE Field
Network module.
Remove the module mounted on the 65th slot or
later.
