• There is no response from the target
CPU module in a multiple CPU
system during initial communication.
• In a multiple CPU system, a CPU
module incompatible with the
multiple CPU system was mounted.
• Reset the CPU module and RUN it
again. If the same error is displayed
again, this suggests the hardware
fault of any of the CPU modules.
(Contact your local Mitsubishi
representative.)
• Remove the CPU module
incompatible with the multiple CPU
system from the main base unit.
Or, replace the CPU module
incompatible with the multiple CPU
system with the compatible one.

There is no response from the target
CPU module in a multiple CPU system
at initial communication stage.
Reset the CPU module and RUN it
again. If the same error is displayed
again, this suggests the hardware fault
of any of the CPU modules. (Contact
your local Mitsubishi representative.)
7004
In a multiple CPU system, a data error
occurred in communication between
the CPU modules.
• Check the system configuration to
see if modules are mounted in
excess of the number of I/O points.
• When there are no problems in the
system configuration, this indicates
the CPU module hardware is faulty.
(Contact your local Mitsubishi
representative, explaining a detailed
description of the problem.)

• 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.)
• In a multiple CPU system, the PC
CPU module used the QFB (bus
interface driver) of version 1.06 or
earlier.
• Read the individual information of
the error using GX Developer, 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.
• Use the PC CPU module that uses
the QFB of version 1.07 or later.
• Reset CPU No. 1 and restart the
multiple CPU system.
