Error details and cause
Failure of the main or extension base unit
was detected.
A bus error was detected when power is
turned on or the CPU module is reset.
The error of connected CPU was detected
at the multiple CPU high speed
transmission.
Error (Disconnected) with other CPU was
detected at the multiple CPU high speed
transmission.
Communication timeout with other CPU was
detected at the multiple CPU high speed
transmission.
Error (Disconnected) with other CPU was
detected at the multiple CPU high speed
transmission.
The error of the multiple CPU high speed
transmission main base unit was detected
at the multiple CPU high speed
transmission.
(The error of the multiple CPU high speed
transmission was detected.)
The error of the multiple CPU high speed
transmission main base unit was detected
at the multiple CPU high speed
transmission.
(The error of the multiple CPU high speed
transmission was detected.)
The error of the multiple CPU high speed
transmission main base unit was detected
at the multiple CPU high speed
transmission.
(The error of the multiple CPU high speed
transmission was detected.)
• A momentary power failure occurred in
the power supply.
(The number of detected momentary
power failures can be confirmed by the
CCPU_GetPowerStatus function.)
• The power supply was turned off.
On the redundant power supply base unit,
the voltage of one of the power supplies
dropped.
In the redundant power supply system, a
failure was detected in one of the redundant
power supply modules.
• The battery voltage of the CPU module
has dropped to the specified value or
less.
• The lead connector of the battery in the
CPU module is not connected.
• The lead connector of the CPU module
battery is not securely engaged.
APPENDICES
Corrective action
• Reset the CPU module and set it to RUN
again.
• If the same error is displayed again,
check the modules and replace a faulty
module.
• Take a preventive measure against
noise.
• Check if the CPU module is mounted on
the main base unit correctly.
• Reset the CPU module and set it to RUN
again.
• If the same error is displayed again,
check the modules and replace a faulty
module.
• Reset the CPU module and set it to RUN
again.
• If the same error is displayed again,
check the modules and replace a faulty
module.
• Take a preventive measure against
noise.

power supply module on the redundant
power supply base unit.
Check the modules and replace a faulty
module.
• Replace the battery.
• Connect the lead connector.
• Check the lead connector of the CPU
module for looseness. Firmly engage the
connector if it is loose.
