im looking for an expression that is 1 every 2 timesteps.
I tried to build the expression with a sin function but somehow it does not work propably.
is there a easier way?

Your way is close but you have the expression slightly wrong. And are you interested in every 2 "timesteps" or do you want this as a function of time?
For timesteps your variable needs to be ctstep not Time.
Also, your sin function would need to be
cos(ctstep*pi) in order to get it to "1" on every even step.
But I would be afraid of roundoff error on this and wouldnt trust it to return true using a boolean to evaluate it, so I would switch to a step function. Perhaps:
