A01 MULTI CPU ERROR 2000
Details
I/O module information power ON is changed.
- I/O module (or intelligent function module) not installed properly or installed on the base unit.
Remedy
Read the common information of the error using a programming tool, and check and/or change the
module that corresponds to the numerical value (module number) there.
- Alternatively, monitor the special registers SD1400 to SD1431 using GX Developer, 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.

A01 MULTI CPU ERROR 2100
Details
- In the I/O assignment setting of PLC parameter, intelligent function module was allocated to an I/O
module or vice versa.
- In the I/O assignment setting of PLC parameter, a module other than CPU (or nothing) was allocated
to the location of a CPU module or vice versa.
- In the I/O assignment setting of the PLC parameter, general switch setting was made to the module
that has no general switch setting.
- In the I/O assignment setting of the PLC parameter dialog box, the number of points assigned to the
intelligent function module is less than the number of points of the mounted module.
Remedy
- Make the PLC parameter I/O assignment setting again so it is consistent with the actual status of the
intelligent function module and the CPU module.
- Delete the switch setting in the I/O assignment setting of the PLC parameter.
