Error
Code Error Contents and Cause
(SD0)
In a multiple CPU system, a CPU
module incompatible with the multiple
CPU system is mounted.
The I/O module status is different from
the I/O module information at power
ON.
• I/O module (or intelligent function
module) is not installed properly or
installed on the base unit.
2000
I/O module information power ON is
changed.
• I/O module (or intelligent function
module/special function module) not
installed properly or installed on the
base unit.
During operation, a module was
2001 mounted on the slot where the empty
setting of the CPU module was made.
*3 The function version is B or later.
*4 The function version is A.
*5 The module whose first 5 digits of serial No. is 04101 or later.
*6 The module whose first 5 digits of serial No. is 09012 or later.
*7 The Universal model QCPU except the Q02UCPU.
*8 This applies to the QnUDE(H)CPU.
*9 The module whose first 5 digits of serial No. is 10042 or later.
Corrective Action
Replace the CPU module incompatible
with the multiple CPU system with a
CPU module compatible with the
multiple CPU system.
Read the error common information at
the GX Developer, and check and/or
change the module that corresponds to
the numerical value (module number)
there.
Alternatively, monitor special registers
SD150 to SD157 using GX Developer,
and check and replace the module
where the bit of its data is "1".
• Read the common information of the
error using the peripheral device, and
check and/or change the module that
corresponds to the numerical value
(module number) there.
• Alternatively, monitor the special
registers SD1400 to SD1431 at a
peripheral device, and change the
fuse at the output module whose bit
has a value of "1".
• When a GOT is bus-connected to the
main base unit or extension base
unit, check the connection status of
the extension cable and the
grounding status of the GOT.
During operation, do not mount a
module on the slot where the empty
setting of the CPU module was made.
