Remote I/O Area Attributes
The NE1A-series Controller’s remote I/O area has the following attributes.
All values in the safety remote I/O area will be cleared if the operating mode is
changed. If a communications error occurs, all data for the connection for
which the error occurred will be cleared.
Note

Hold
The last data in the slave output area (inputs to a user application
program) is held when a communications (connection) error
occurs.
The last data in the slave input area (outputs to a Standard
