Types of Errors

The type of error that has occurred can be identified by checking the indicators on the front of the CPU
Unit and the Power Supply Unit, or by using the CX-Programmer to check the error status. The errors
detected by the CPU Unit are listed in the following table.
For details on errors that are not detected by the CPU Unit, refer to 6-3 Non-CPU Unit Errors and Rem-
edies.

*1 The indicator status is the same for CPU errors and fatal errors, but they can be distinguished because a Programming
Device can be connected when a fatal error occurs, but not when a CPU error occurs.
*2 For details on fatal errors and non-fatal errors, refer to A-3 Fatal and Non-fatal Error Details.
*3 CJ2H-CPU6@-EIP only.
Note The indicator status shows the status of the errors that have occurred in RUN or MONITOR mode.
