Error and cause
code
[MULTI CPU DOWN]
In a multiple CPU system, a data error occurred in
communication between the CPU modules.
■Collateral information
7004
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• Always
[MULTI EXE. ERROR]
• In a multiple CPU system, a faulty CPU module
was mounted.
• In a multiple CPU system, a CPU module
incompatible with the multiple CPU system was
mounted. (The CPU module compatible with the
multiple CPU system was used to detect an
error.)
• In a multiple CPU system, any of the CPU No. 2
to 4 was reset with power ON. (The CPU whose
reset state was cancelled was used to detect an
error.)
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[MULTI EXE. ERROR]
In a multiple CPU system, the version of the
software package (PPC-DRV-01)
CPU module is 1.06 or earlier.
■Collateral information
7010 • Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[MULTI EXE. ERROR]
The Q172(H)CPU(N) or Q173(H)CPU(N) is
mounted on the multiple CPU high-speed main
base unit (Q3DB). (This may result in a module
failure.)
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[MULTI EXE. ERROR]
The Universal model QCPU (except Q02UCPU)
and Q172(H)CPU(N) are mounted on the same
base unit. (This may result in a module failure.)
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
Corrective action
• Check the system configuration to see if
modules are mounted in excess of the
number of I/O points.
• If there is no problem in the system
configuration, the cause is a hardware
failure of the CPU module. Please consult
your local Mitsubishi representative.
• Read the common information of the error
using the programming tool and replace the
faulty CPU module.
• Replace the CPU module with the one
compatible with the multiple CPU system.
• Do not reset any of the No. 2 to 4 CPU
modules.
• Reset CPU No. 1 and restart the multiple
CPU system.
*2
for the PC
Change the software package (PPC-DRV-
*2
01) for the PC CPU module to the version
1.07 or later.
Replace the Q172(H)CPU(N) and
Q173(H)CPU(N) with the Motion CPU
compatible with the multiple CPU high-speed
main base unit.
Check the QCPU and Motion CPU that can
be used in a multiple CPU system, and
change the system configuration.
