5000
The scan time of the initial execution type program exceeded the
initial execution monitoring time designated in the PLC RAS setting of
the parameter.
5001
The program scan time exceeded the WDT setting value designated
in the PLC RAS setting of the parameter.
Read the individual information of the error using a
peripheral device, check its value (time), and shorten the
scan time.
5010
The low speed program execution time designated in the PLC RAS
setting of the parameter exceeded the surplus time of the constant
scan.
Review the constant scan time and low speed program
execution time in the parameter in order to ensure the
surplus time of constant scan sufficiently.
5011
The scan time of the low speed scan type exceeded the low speed
execution monitoring time designated in the PLC RAS setting of the
parameter.
Read the individual information of the error using a
peripheral device, check its value (time), and shorten the
scan time.
6000
The programs and parameters of the control and standby system in
the redundant system are not the same.
Synchronize the programs and parameters of the control
and standby system.
6010
The operational status of the control and standby system in the
redundant system is not the same.
Synchronize the operation statuses of the control and
standby system.
Q4AR
6100
A tracking memory fault of CPU module was detected at initial
processing.
This suggests a CPU module hardware fault. Contact your
nearest Mitsubishi representative.
Change the CPU modules in order of the standby system
CPU module and control system CPU module.
6101 The CPU module detected a fault during the handshake for tracking. Check the condition of the other stations.
Q4AR
6200
The standby system is switched to the control system in a redundant
system.
Check the control system condition.
6210
The control system has been switched to the standby system in a
redundant system.
Check the control system condition.
6220
Since the standby system is in an error or similar status in the
redundant system, the control system cannot be switched to the
standby system.
Check the standby system condition.
6221 Switching is disabled because of a bus switching module fault.
This suggests a bus switching module hardware fault.
Contact your nearest Mitsubishi representative.
6222
During initial processing, the switching cannot be executed since the
multiplex master station of remote I/O network is installed to the
standby station.
Check the remote I/O network setting.
Q4AR
(1) In a multiple CPU system, a CPU module fault occurred at the
CPU where "All station stop by stop error of PLC" was selected in
the operating mode.
(2) In a multiple CPU system, QCPU of function version A was
mounted.
(1 Read the individual information of the error, check the
error of the CPU resulting in the CPU module fault, and
remove the error.
(2) Remove the QCPU of function version A from the base
module.
7000
In a multiple CPU system, a stop error occurs at CPU No.1 at
power-on and the other CPU cannot start. (This error occurred at
CPU No.2 to No.4)
Read the individual information of the error, check the error
of the CPU resulting in the CPU module fault, and remove
the error.
7002
(1) There is no response from the communication target CPU
module at initial communication of in a multiple CPU system.
(2) In a multiple CPU system, QCPU of function version A was
mounted.
(1) Reset the CPU module and make a RUN again. If the
same error is displayed again, this suggests any CPU
module hardware fault. Contact your nearest Mitsubishi
representative.
(2) Remove the QCPU of function version A from the base
module.
7003
There is no response from the communication target CPU module at
initial communication in a multiple CPU system.
Reset the CPU module and make a RUN again. If the same
error is displayed again, this suggests any CPU module
hardware fault. Contact your nearest Mitsubishi
representative.
7010
(1) In a multiple CPU system, a faulty CPU module is mounted.
(2) In a multiple CPU system, QCPU of function version A is
mounted.
(QCPU of function version B is used to detect an error.)
(3) In a multiple CPU system, any of the CPU No. 2 to 4 was reset
during power ON.
(An error occurs in only the CPU where canceled the reset.)
(1) Read the individual information of the error, and replace
the faulty CPU module.
(2) Replace the CPU of the function version A with the CPU
of the function version B.
(3) Do not reset any of the No. 2 to 4 CPU modules.
Reset the QCPU of CPU No.1 and restart up the
multiple CPU system.
7020
In a multiple CPU system, an CPU fault occurred in the CPU "where
system stop was not selected" in the operation mode.
(An error is detected in the QCPU other than the CPU where no CPU
fault occurred.)
Read the individual information of the error, check the error
of the CPU resulting in the CPU module fault, and remove
the error.
