NE1A-series Controller Operating Modes
8-1-1
Operating Mode Overview
The following modes are supported by the NE1A-series Controller.
SELF-DIAGNOSTIC Mode
The NE1A-series Controller performs self-diagnosis internally. This is
required to ensure safety functions.
CONFIGURING Mode
CONFIGURING Mode exists while waiting for the completion of configuration
from the Network Configurator. The NE1A-series Controller switches to Con-
figurating Mode when it is not yet configured after initialization has been com-
pleted or when there is an error in the configuration data.
IDLE Mode
IDLE Mode exists while waiting for RUN Mode after initialization has been
completed.
Non-safety-related control (standard I/O communications, message communi-
cations, etc.) is supported.
RUN Mode
Safety control (user program, safety I/O communications, safety I/O refresh
control) and non-safety-related control (standard I/O communications, mes-
sage communications, etc.) are both supported.
ABORT State
The NE1A-series Controller switches to Abort Mode if the Controller’s switch
setting is changed after the configuration has been completed. The Controller
stops all functions except for message communications and puts them in the
safety state.
When Controller’s switch settings must be changed due to user system
changes, reset the Controller to the default settings. Refer to
Section 7 Other
Functions
for the reset function.
CRITICAL ERROR State
The NE1A-series Controller switches to this state if a critical error occurs.
The Controller stops all functions and puts them in the safety state.
