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.
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
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.
• 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.

• More than applicable number of
extension base units have been
used.
• When a GOT was bus-connected,
the CPU module was reset while the
power of the GOT was OFF.
• Use the allowable number of
extension base units or less.
• Power on the PLC and GOT again.
