Hi, Is there a way to make the "Analaog Comparator" On and Off threshold parameters as retentive? I have an application where I would like these values to be parametrizable from the customizable web page. Now I have the values coming from VW0 (On threshold) and VW2 (Off threshold) but the values are initilized to 0 after power cycle. Example in attachment. So in more detail: The B004 blocks parameters 'On' and 'Off' must be given as user input from the customizable web page and these values should keep there values during power off. How to manage this ? Regards, Jarko ------------------------------------------------------------------------------------------ |

I created something there. Look if it suits you. The setpoints of the parameters "ON" and "OFF" of the analogue comparator are stored in a MAX / MIN block if the value is greater than zero and only if it changes and are then written back to the VM area.
