Error code list (2000 to 2999)

The following shows the error messages from the error code 2000 to 2999, the contents and 
causes of the errors, and the corrective actions for the errors.

2000

[UNIT VERIFY ERR.]
In a multiple CPU system, a CPU module 
incompatible with the multiple CPU system is 
mounted.
■Collateral information

• Common Information:Module No. (Slot No.)

[For Remote I/O network]
Network No./Station No.

• Individual Information:–

■Diagnostic Timing

• When an END instruction executed

Replace the CPU module incompatible with the 
multiple CPU system with a CPU module 
compatible with the multiple CPU system.

[UNIT VERIFY ERR.]
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.

■Collateral information

• Common Information:Module No. (Slot No.)

[For Remote I/O network]
Network No./Station No.

• Individual Information:–

■Diagnostic Timing

• When an END instruction executed

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".

Q00J/Q00/Q01

[UNIT VERIFY ERR.]
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.

■Collateral information

• Common Information:Module No. (Slot No.)

[For Remote I/O network]
Network No./Station No.

• Individual Information:–

■Diagnostic Timing

• When an END instruction executed

• 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.
