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 common information of the error using
the programming tool to identify the numeric
value (module No.). Check the module
corresponding to the value and replace it as
necessary.
• Monitor SD150 to SD157 using the
programming tool to identify the module whose
data bit it is "1". Then check the module and
replace it as necessary.

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

• Always
• Read common information of the error using
the programming tool to identify the numeric
value (module No.). Check the module
corresponding to the value and replace it as
necessary.
• Monitor SD1400 to SD1431 with the
programming tool to identify the module whose
data bit it is "1". Then check the module and
replace it as necessary.
• 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.

[BASE LAY ERROR]
• 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.
■Collateral information
• Common information: Base No.
• Individual information:-
