2 MULTIPLE CPU SYSTEM
Error code Error contents and cause Corrective action Remark
3001 Parameter contents have been destroyed.
(1) Read the error detailed information at the peripheral device,
check and correct the parameter items corresponding to the
numerical values (parameter No.).
(2) If the error still occurred after correcting of the parameter
settings, it may be an error for internal RAM of CPU or
memory. Explain the error symptom and get advice from our
sales representative.
3010
The number of CPU modules set in the parameter differ from the real
installation in a Multiple CPU system.
Match (preset count of Multiple CPU setting) – (CPU (empty)
setting in I/O assignment) with the real installation of CPUs.
3012
The reference CPU No. set in the parameter differ from the setting in
a Multiple CPU system.
Match the setting in the parameter with that of the reference CPU
No. (CPU No.1).
3013
Multiple CPU automatic refresh setting is any of the followings in a
Multiple CPU system.
(1) When a bit device is used as a refresh device, a number except a
multiple of 16 is set as the refresh first device.
(2) A non-specifiable device is specified.
(3) The number of transmitting points is an odd number.
Check the following in the Multiple CPU automatic refresh
parameters and make correction.
(1) When specifying the bit device, specify a multiple of 16 for the
refresh first device.
(2) Specify the device that may be specified for the refresh
device.
(3) Set the number of transmitting points to an even number.
In a Multiple CPU system, a CPU fault occurred at the CPU where "all
station stop by stop error of CPU was selected" in the operating
mode.
(It occurs in the CPU except for the CPU that suspension of a system
is chosen.)
7000
In a Multiple CPU system, CPU No.1 resulted in stop error at power-
on and the other CPU cannot start. (This error occurred at CPU No.2
to 4)
Read the individual information of the error at the peripheral
device, check the error of the CPU resulting in CPU fault, and
remove the error.
7002
7003
At initial communication in a Multiple CPU system, no response is
given back from the target CPU of initial communication.
Reset the PLC CPU and run it again. If the same error is
displayed again, it is a hardware fault of any CPU. Explain the
error symptom and get advice from our sales representative.
7010
(1) A fault CPU is installed in a Multiple CPU system.
(2) CPUs of unmatched versions are installed in a Multiple CPU
system.
(This error is detected at the PLC CPU of function version B.)
(3) Any CPU No. among CPU No.2 to 4 was reset, after power supply
on a Multiple CPU system.
(This error occurs by the reset CPU No..)
The CPU No. of the function version A or the break down module
is exchanged for the CPU module of the function version B, after
it began to read the individual information of the error at the
peripheral devices.
7020
In a Multiple CPU system, a CPU fault occurred at the CPU where "all
station stop by stop error of CPU was not selected" in the operation
mode. (The error is detected at the PLC CPU of other than the CPU
No. where the CPU fault occurred.)
Read the individual information of the error at the peripheral
device, check the error of the CPU resulting in CPU fault, and
remove the error.
10000
The error which a Motion CPU was characteristic of occurred.
It is set when an error all to set with the system setting error, the
Motion CPU is detected. (Minor error, major error, servo error and
various errors)
Use the software package of the applicable CPU module to
check the details of the error that occurred.
: It occurs in the CPU (CPU No.) which detected a error.
: It occurs in all CPU No. at the time of the Multiple CPU composition.
: It does not occur.
