Error
Error Contents and Cause
Code
[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 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.
2150 ■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset/At writing to programmable
controller
[SP. UNIT VER. ERR.]
Either of the following modules incompatible with
the redundant system has been mounted in a
redundant system.
• MELSECNET/H modules
• Ethernet modules
2151
• CC-Link IE controller network modules
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset/At writing to programmable
controller
[SYSTEM LAY ERR.]
A module which the LCPU cannot recognize is
connected.
■Collateral information
2170
• Common information:-
• Individual information:-
■Diagnostic Timing

Corrective Action
• 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.
• 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.
Ensure that the module supports the use in a
redundant system when using any of the following
modules.
• MELSECNET/H modules
• Ethernet modules
• CC-Link IE controller network modules
• Disconnect the module that cannot be
recognized.
• 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, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem)
