Code Error Contents and Cause
(SD0)
[UNIT VERIFY ERR.]
In a multiple CPU system, a CPU module incom-
patible with the multiple CPU system is mounted.
■Collateral information
• Common Information:Module No. (Slot No.)
• Individual Information:–
■Diagnostic Timing
• When an END instruction executed
[UNIT VERIFY ERR.]
The I/O module status is different from the I/O mod-
ule 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.)
2000
• Individual Information:–
■Diagnostic Timing
• When an END instruction executed
[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.)
• Individual Information:–
■Diagnostic Timing
• When an END instruction executed
[UNIT VERIFY ERR.]
During operation, a module was mounted on the
slot where the empty setting of the CPU module
was made.
2001 ■Collateral information
• Common Information:Module No. (CPU No.)
• Individual Information:–
■Diagnostic Timing
• When an END instruction executed
[BASE LAY ERROR]
• More than applicable number of extension base
units have been used.
• When a GOT was bus-connected, the CPU mod-
ule was reset while the power of the GOT was
2010
OFF.
■Collateral information
• Common Information:Base No.
• Individual Information:–
■Diagnostic Timing
• At power ON/At reset
*1 CPU operation can be set in the parameters at error occurrence. (LED indication varies.)
*2 Either error stop or continue can be selected for each module by the parameters.
*3 The function version is B or later.

Replace the CPU module incompatible with the
multiple CPU system with a CPU module compati-
[For Remote I/O network]
ble with the multiple CPU system.
Network No./Station No.
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
[For Remote I/O network]
SD157 using GX Developer, and check and replace
Network No./Station No.
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
[For Remote I/O network]
has a value of "1".
Network No./Station No.
• 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.
• Use the allowable number of extension base
units or less.
• Power on the Progammable Controller and GOT
again.
