Error and cause
code
[SP.UNIT LAY ERR.]
• A module which the QCPU cannot recognize
has been installed.
• There was no response from the intelligent
function module/special function module.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
2125
[SP.UNIT LAY ERR.]
• A module which the LCPU cannot recognize
has been connected.
• There was no response from the intelligent
function module.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[SP.UNIT LAY ERR.]
The CPU module configuration in the multiple
CPU system is either of the following.
• There are empty slots between the QCPU and
QCPU/motion controller.
• A module other than the High Performance
model QCPU/Process CPU (including the
2126
motion controller) is mounted on the left-hand
side of the High Performance model
QCPU/Process CPU.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[SP.UNIT LAY ERR.]
The unusable module is mounted on the extension
base unit in the redundant system.
■Collateral information
2128
• Common information: Module No. (Slot No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[SP.UNIT LAY ERR.]
An A/QnA series module that cannot be used is
mounted.
■Collateral information
2129
• Common information: Module No. (Slot No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[SP. UNIT VER. ERR.]
In a multiple CPU system, the control CPU of the
intelligent function module incompatible with the
multiple CPU system is set to other than CPU
No.1.

Corrective action
• Install a usable module.
• The intelligent function module/special
function module is experiencing a
hardware fault. Please consult your local
Mitsubishi representative.
• Connect an applicable module.
• 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.
• Mount modules on the available slots so
that the empty slots will be located on the
right-hand side of the CPU module.
• Remove the modules mounted on the left
of the High Performance model QCPU or
Process CPU. Mount a High Performance
model QCPU or Process CPU on those
slots. Mount the motion CPU on the right-
hand side of the High Performance model
QCPU/Process CPU.
Remove the unusable module from the
extension base unit.
Remove the A/QnA series module that
cannot be used.
• Change the intelligent function module for
the one compatible with the multiple CPU
system (function version B).
• Change the setting of the control CPU of
the intelligent function module incompatible
with the multiple CPU system to CPU No.1.
