*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 Refer to 6-1-8 Fatal Errors and 6-1-10 Non-fatal Errors for details on fatal and non-fatal errors.
Note The indicator status shows the status of the errors that have occurred in RUN or MONITOR mode.
Confirm the error category by referring to the status of the CPU Unit indicators, investigate the cause for
the error in the error tables, and take corrective actions.
