Hello,  
I would like reset dosignal1 according condition other “dosignal2=1”.  
Becauase in Cross Connection I can only Set signal as “Resultant”, not possilbe reset.  
And In initial state a need both signals as 0.  
It is possible, how?

Thank you in advance  
Jiri Muller

Maybe make another cross connection, same signals but invert to do the reset. Set a default value of 0 in the signal configuration.

So then, try another signal, virtual even, cross connected to the resultant and invert it.
