Error
Code Error Contents and Cause
(SD0)
I/O module information power ON is
changed.
• I/O module (or special function
2000
module) not installed properly or
installed on the base unit.
In PLC parameter I/O allocation
settings, a special function module was
2100 allocated to a location reserved for an I/
O module. Or, the opposite has
happened.
13 or more special function modules
(not counting the A(1S)I61) capable of
2101
sending an interrupt to the CPU module
have been installed.
Seven or more serial communication
2102 modules (excludes A(1S)J71QC24)
have been installed.
Two or more A(1S)I61 interrupt modules
2103
have been mounted.
Corrective Action
• 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.
Reset the PLC parameter I/O allocation
setting to conform with the actual status
of the special function modules.
Keep the number of special function
modules that can initiate an interrupt
(with the exception of the A(1S)I61
module) to 12 or fewer.
Keep the number of serial
communication modules (excludes
A(1S)J71QU24) installed to six or fewer.
Install only 1 A(1S)I61 module.
