Appendix
Code Error name Cause/Action
0FA CPU error The CPU is not operating properly.
Cause: [1] Faulty
CPU
[2] Malfunction due to noise
Action: If the alarm generates again after reconnecting the power, please
contact IAI.
0FB FPGA error The FPGA is not operating normally.
Cause: [1] Malfunction due to the effect of noise, etc.
[2] The FPGA itself is faulty.
[3] Faulty circuit component around the FPGA
[4] Inappropriate board installation in the controller
Action: Reconnect the power.
If the error occurs again, check for presence of noise. If a spare
controller is available, replace the problem controller with the spare
controller. A recurring error with the spare controller suggests
presence of noise.
If the cause cannot be identified, contact IAI.
