I want an output that was 1 before powerdown, to be 1 again at powerup. For 0 signal the same : 0 before powerdown = 0 after powerup.
The combination of the two parameters for a digital output are not completely clear to me :
'Signal value at system failuren and at power failure',
and 'Store signal value at power failure'.
What would happen if I activate only the first parameter?
Do I need to activate both parameters to achieve my goal?
