A01 MULTI CPU ERROR 1434
Details
- A communication error with another CPU was detected during the multi-CPUs high-speed
communication.
Remedy
- Take noise reduction measures.
- Check the configuration of the main base unit in the CPU module.
- Reset and restart the CPU module. If the same error is displayed again, this suggests a CPU
module hardware fault. Contact your local service center.
A01 MULTI CPU ERROR 1435
Details
- A communication error with another CPU was detected during the multi-CPUs high-speed
communication.
Remedy
- Take noise reduction measures.
- Check the configuration of the main base unit in the CPU module.
- Reset and restart the CPU module. If the same error is displayed again, this suggests a CPU
module hardware fault. Contact your local service center.
A01 MULTI CPU ERROR 1436
Details
A fault is detected on the main base module in the multi-CPUs high-speed communication.
(An error was detected on the multi-CPUs high-speed communication bus.).
Remedy
- Reset and restart the CPU module. If the same error is displayed again, this suggests a CPU
module hardware fault. Contact your local service center.
A01 MULTI CPU ERROR 1437
Details
A fault is detected on the main base module in the multi-CPUs high-speed communication.
(An error was detected on the multi-CPUs high-speed communication bus.)
Remedy
- Take noise reduction measures.
- Check the configuration of the main base unit in the CPU module.
- Reset and restart the CPU module. If the same error is displayed again, this suggests a CPU
module hardware fault. Contact your local service center.
A01 MULTI CPU ERROR 1500
Details
- A momentary power supply interruption has occurred.
- The power supply went off.
Remedy
- Check the power supply.
A01 MULTI CPU ERROR 1600
Details
- The battery voltage in the CPU module has dropped below stipulated level.
Remedy
- Change the battery.
Details
- The lead connector of the CPU module battery is not connected.
Remedy
- If the battery is for program memory, standard RAM or for the back-up power function, install
a lead connector.
A01 MULTI CPU ERROR 1601
Details
- Voltage of the battery on memory card 1 has dropped below stipulated level.
Remedy
- Change the battery.
A01 MULTI CPU ERROR 1610
Details
- The number of writing to the FLashROM (the standard RAM or the area reserved by the sys-
tem) exceeded one hundred thousand times.
(Number of writing>100,000 times)- Voltage of the battery on memory card 1 has dropped
below stipulated level.
Remedy
- Replace the CPU modules.
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 con-
nection status of the extension cable and the grounding status of the GOT.
A01 MULTI CPU ERROR 2001
Details
- During operation, a module was mounted on the slot where the empty setting of the CPU
module was made.
Remedy
- During operation, do not mount a module on the slot where the empty setting of the CPU
module was made.
