Error
Code Error Contents and Cause
(SD0)
The start X/Y set in the PLC
parameter's I/O assignment settings is
2107
overlapped with the one for another
module.
A(1S)J71LP21 or A(1S)J71BR11 for
2108 use with the AnUCPU network module
has been installed.
The control system and standby system
module configurations are different
2109
when a redundant system is in the
backup mode.
• The location designated by the
FROM/TO instruction set is not the
special function module.
• The module that does not include
buffer memory has been specified by
2110 the FROM/TO instruction.
• The special function module, Network
module being accessed is faulty.
• Station not loaded was specified
using the instruction whose target
was the CPU share memory.
• The location designated by a link
direct device (J \ ) is not a network
module.
2111
• The I/O module (special function
module) was nearly removed,
completely removed, or mounted
during running.
• The module other than special
function module is specified by the
special function module dedicated
instruction.
Or, it is not the corresponding special
2112
function module.
• The module model specified by the
special function module dedicated
instruction and that specified by the
parameter I/O assignment is different.
Corrective Action
Make the PLC parameter's I/O
assignment setting again so it is
consistent with the actual status of the
special function modules.
Replace the network module to
A(1S)J71QLP21 or A(1S)J71QBR11.
Check the module configuration of the
standby system.
• Read the individual information of the
error using the GX Developer, check
the FROM/TO instruction that
corresponds to that numerical value
(program error location), and correct
when necessary.
• The special function module that was
accessed is experiencing a hardware
fault. Therefore, change the faulty
module. Alternatively, contact your
local Mitsubishi representative.
• Read the individual information of the
error using a peripheral device, and
check the special function module
dedicated instruction (network
instruction) that corresponds to the
value (program error part) to make
modification.
• Set the module model by PLC
parameter I/O assignment according
to the special function module
dedicated instruction setting.
Example) Although AJ71QC24N is
used actually, AJ71QC24 is set.
