A01 MULTI CPU ERROR 2116
Details
- An instruction that does not allow the module under the control of another CPU to be spec-
ified is being used for a similar task.
Remedy
- Read the individual information of the error using a programming tool and check the special
function module dedicated instruction (network instruction) that corresponds to the value
(program error part) to make modification.
A01 MULTI CPU ERROR 2124
Details
- A module is installed to the 65th or higher slot.
- A module is installed to the slot whose number is greater than the number of slots specified
in the base setting.
- A module is installed to the location corresponding to the I/O points of the 4,096 or greater.
- A module is installed to the slot whose assigned I/O range includes the limit of.
Remedy
- Remove the module installed to the 65th or later slot.
- Remove the module installed at the slot whose number is greater than the number of slots
specified in the base setting.
- Remove the module installed to the location of I/O points, 4,096 or greater.
- Replace the last module to a module which does not exceed the 4,096th point.
A01 MULTI CPU ERROR 2125
Details
- A module which the QCPU cannot recognize has been installed.
- There was no response form the intelligent function module/special function module.
Remedy
- Install a usable module.
- The intelligent function module is experiencing a hardware fault. Contact your local service
center.
A01 MULTI CPU ERROR 2140
Details
- Motion CPU (Q172LX, Q172EX (-S1, S2, S3) or Q173PX(-S1)) is mounted to the CPU slot
or slot No. 0 to 2.(QnUD(H)CPU does not lead this error.)
Remedy
- Remove the motion CPU that is mounted to the CPU slot or slot No. 0 to 2.
A01 MULTI CPU ERROR 2150
Details
- In a multiple CPU system, the control CPU of the intelligent function module incompatible
with the multiple CPU system is set to other than CPU No.1.
Remedy
- Change the intelligent function module for the one compatible with the multiple CPU system
(function version B or later).
- Change the setting of the control CPU of the intelligent function module incompatible with
the multiple CPU system to CPU No.1.
A01 MULTI CPU ERROR 2200
Details
- No parameter file is found all through the drives where the parameter should be validated.
Remedy
- Write the parameter file to PLC of the drive that validates the parameter.
A01 MULTI CPU ERROR 2210
Details
- The contents of the boot file are incorrect.
Remedy
- Check the boot setting.
A01 MULTI CPU ERROR 2211
Details
- File formatting failed at a boot.
Remedy
- Reboot.

A01 MULTI CPU ERROR 2300
Details
- A memory card was removed without switching the memory card in/out switch OFF.
- The memory card in/out switch is turned ON although a memory card is not actually in-
stalled.
Remedy
- Remove memory card after placing the memory card in/out switch OFF.
- Turn on the card insert switch after inserting a memory card.
A01 MULTI CPU ERROR 2301
Details
- The memory card has not been formatted.
- Memory card format status is incorrect.
Remedy
- Format memory card.
- Reformat memory card.
Details
- A fault of the SRAM card was detected.
(This error occurs when the automatic formatting is not set.)
