[SP.UNIT LAY ERR.]
• In the I/O Assignment tab of "PLC Parameter",
"Intelligent" (intelligent function module) or a
branch module is set for the position where an
I/O module is connected.
• In the I/O Assignment tab of "PLC Parameter",
"Input" (input module), "Output" (output
module), or a branch module is set for the
position where an intelligent function module is
connected.
• In the I/O Assignment tab of "PLC Parameter",
"Input" (input module), "Output" (output
module), or "Intelligent" (intelligent function
module) is set for the position where a branch
module is connected.
• In the I/O Assignment tab of "PLC Parameter",
switch settings are configured for the module
that does not support the setting.

• In the I/O Assignment tab of "PLC Parameter",
the number of points assigned to the intelligent
function module is less than that of the mounted
module.

[SP.UNIT LAY ERR.]
In the PLC parameter setting, setting content for
the adapter type is different from the ones for the
mounted adapter. Or no adapter has been set.

[SP.UNIT LAY ERR.]
13 or more A-series special function modules
(except for the A1SI61/AI61(-S1)) that can initiate
an interrupt to the CPU module have been
installed.

Total of 7 or more MELSECNET, MELSECNET/B
local station data link module (A1SJ71AP23Q,
A1SJ71AR23Q, A1SJ71AT23BQ), A/QnA
intelligent communication module (A1SD51,
AD51(H)(-S3)), A/QnA JEMANET(JPCN-1)
master module (A1SJ71J92-S3, AJ71J92-S3),
2102
A/QnA external failure diagnostics module
(AD51FD-S3), and A/QnA paging interface
module (A1SD21-S1) have been installed.

• Set the I/O assignment again so that the
setting matches with the mounting status of
the intelligent function module, CPU
module, or branch module.
• Delete the switch setting in the I/O
assignment setting tab of "PLC parameter".
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a hardware failure of the CPU
module, I/O module, intelligent function
module, END cover, branch module, or
extension module. Please consult your
local Mitsubishi representative.
• Make setting again to match the PLC
parameter adapter type setting with the
mounted adapter.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
(fixed)
cause is a hardware failure of the CPU
H
module, RS-232 adapter, and RS-422/485
adapter. Please consult your local
Mitsubishi representative.
Reduce the number of A series special
function modules (except the A1SI61/AI61(-
S1)) that can start interrupt programs to the
CPU module to 12 or less.
Reduce the total number of MELSECNET,
MELSECNET/B local station data link
modules, A/QnA intelligent communication
modules, A/QnA JEMANET(JPCN-1) master
modules, A/QnA external failure diagnostics
modules, and A/QnA paging interface
modules in the system to six or less.
