12-1 Error Categories
NE1A-series Controller errors can be categorized into the following three cat-
egories:
Nonfatal Errors
The part where an error has occurred stops at each local I/O or safety I/O
connection terminal and places it in the safety state. The Controller, however,
continues in RUN Mode.
Abort Errors
The NE1A-series Controller completely stops safety functions and places
them in the safety state when this error occurs. To enable checking the error
state, explicit message communications or partial Network Configurator func-
tions are supported.
Critical Error
The NE1A-series Controller completely stops its functions when this error
occurs.
Note Refer to 12-5 Errors When Downloading for setting errors that occur during

Note Refer to 12-6 Errors When Resetting for errors that occur when resetting the
NE1A-series Controller.
Note Refer to 12-7 Errors When Changing Modes for errors that occur when chang-
ing the operating mode of the NE1A-series Controller.
