A-3 Fatal and Non-fatal Error Details
This appendix describes the fatal and non-fatal errors that can occur in the CPU Unit.
Operation will stop if a fatal error occurs. Information on the fatal error is displayed on the Error Tab
Page opened from the CX-Programmer's PLC Error Window. Check the details on the error based on
the message that is displayed, and the error flags and error information in the Auxiliary Area, and take
suitable countermeasures. The following list shows the fatal errors.
