STORING DATA ON SD CARD

Hi,

Is it possible to store an analog value on the SD card to be read when needed ?

I would like to use this option to restart from a stored analog value incase of power cycling or a manual interruption .

If you could share some examples so I can use that as inspiration.

Thanks,

Patrick

I have built a aquarium light scheduler program ( thanks to your input  and from toeternietoe)).

it works with a counter and a ramp up/down which generates  a specific analog value in AQ1.

I would like to store the vale in AQ1 to use as a starting point of that counter.

As example: AQ1 is 700 , power goes off and goes on again, it reads 700 and continues the program from there. If the power cut happens during the ramp up, the program would normally restart from 0.

Thanks

You can, however, save voltage fail-safe in the normal way using the program to reuse these values when restarting.

could you explain or show with some examples ?

can someone explain what it means 'to save voltage fail-safe in the normal way using the program to reuse these values (AQ) when restarting the Logo' ?

thanks
