With memory sampling output, the relay is energized on memory start, and deenergized on memory stop. With the output device information on memory stop setting, the relay is energized when you stop memory sampling. These actions cannot be changed.
With the /F1 FAIL/Status output option, there's a memory sampling output setting (only on a DX with the advanced security option (/AS1)) and an output device information on memory stop (status relay) setting. What is the difference between these two?
