Hi, I solve the problem I want to convert the voltage range (temperature) approx.7V-10V to Hz. I used an asynchronous pulse generator the only problem is that the output frequency is nonlinear. I have a range on the pulse generator from 10ms to 100ms in steps of 10 and periodic 1: 1. I would need the output frequency to be from 1Hz to 10Hz or more. but linear. Now it's 5, 5.5, 6.2, 7.1, 8.3, 10, 12.5, 16.6, 25, 50 Can you advise anyone how to connect it, so which block is used to make it linear?

ixo65

Try this.

 Thanks, I'll try it and do you think the logo could handle more than 50Hz? probably not, or?

With increasing voltage you need an increasing frequency, but this a decreasing time. Therefore you have an inverse function and this is nonlinear.

I think, your converter from voltage to frequency with linear function is not possible with a Logo controller.

You misunderstand me, i don't mean y = -x but y = 1 / x. This is a nonlinear function, which cannot be calculated with some blocks in a Logo program. I see no practicable way to solve it with the Logo arithmetic.
