Error code
(SD0)
Error contents and cause Corrective action
1430 The error of self CPU is detected in the Multiple CPU high speed bus.
Reset the CPU module and RUN it again. If the same error is displayed
again, this suggests a CPU module hardware fault.
Explain the error symptom and get advice from our sales representative.
1431
The communication error with other CPU is detected in the Multiple
CPU high speed bus.
(1) Take noise reduction measures.
(2) Check the main base unit mounting status of the CPU module.
(3) Reset the CPU module and RUN it again. If the same error is
displayed again, this suggests a CPU module or base unit hardware
fault.
Explain the error symptom and get advice from our sales
representative.
1432
The communication time out with other CPU is detected in the
Multiple CPU high speed bus.
Reset the CPU module and RUN it again. If the same error is displayed
again, this suggests a CPU module hardware fault.
Explain the error symptom and get advice from our sales representative.

1435
The communication error with other CPU is detected in the Multiple
CPU high speed bus.
(1) Take noise reduction measures.
(2) Check the main base unit mounting status of the CPU module.
(3) Reset the CPU module and RUN it again. If the same error is displayed
again, this suggests a CPU module or base unit hardware fault.
Explain the error symptom and get advice from our sales
representative.
1500
A momentary power supply interruption has occurred.
The power supply went off.
Check the power supply.
1600
(1) The battery voltage in the CPU module has dropped below
stipulated level.
(2) The battery holder unit that install the battery is not mounted to the
CPU module.
(1) Change the battery.
(2) Mount the battery holder unit that installs the battery.
2100
In the I/O assignment setting of PLC CPU, the intelligent function
module was allocated to an I/O module or vice versa.
Make the PLC parameter's I/O assignment setting again so it is consistent
with the actual status of the intelligent function module and the CPU
module.
2107
The first I/O No. set in the system settings is overlapped with the one
for another module.
Make the I/O No. setting again so it is consistent with the actual status of
the modules.
2124
(1) A module is mounted on the 65th or higher slot.
(2) The extension base unit set to "None" is mounted.
(1) Remove the module mounted on the 65th or later slot.
(2) Remove the extension base unit set to "None".
2125
(1) A module which the CPU cannot recognise has been mounted.
(2) There was no response form the intelligent function module.
(1) Install an usable module.
(2) The intelligent function module is experiencing a hardware fault.
Explain the error symptom and get advice from our sales
representative.
2140
The motion modules (Q172DLX, Q172DEX, Q173DPX, Q172LX,
Q172EX (-S1/-S2/-S3), Q173PX (-S1)) are installed in CPU slot or
I/O 0 to 2 slot.
Remove the Motion modules installed CPU slot or I/O 0 to 2 slot.
2150
In a Multiple CPU system, the control CPU of intelligent function
module incompatible with the Multiple CPU system is set to other than
CPU No.1.
(1) Change to the intelligent function module (function version B or later)
compatible with the Multiple CPU system.
(2) Change the control CPU of intelligent function module incompatible with
the Multiple CPU system to CPU No.1.
