31.5.4.1 Saving Output When Logic Stops - Standard Output (LT Series)

This feature saves the output state in the standard output when the logic program stops. When the logic program is restarted, the state value is returned to the allocated variable.

Furthermore, when you enter off-line mode, reset, or turn OFF the power, I/O is initialized and the saved output becomes all OFF.

All terminals use the same output saving settings when the logic stops.
If you select special I/O in the CH terminal settings, you cannot use the CH output terminal for standard output.
