Hello,

For a project I need to activate three inputs individually without another input going high.

As you can see in the added screenshot, these inputs are fed into a UDF which cycle the two outputs based on which input is selected, different running times, and whether a zero position limit switch is actuated or not.

Normally, the three inputs are connected to a rotary switch, so there's no problem of two inputs being activated simultanously, but for this project I'm required to use push buttons, which means that there's a chance that two or more inputs are active at the same time.

Now I can't figure out for the life of me how to make it work.

Ideally, I want the program to either block input 2 and 3 when input 1 is high, or have each input overrule the other two whenever they go high.

I hope you can help me out, because it's getting a bit frustrating

or so,

Try this.

I tried this, and while it sort of works as I described it blocks all signals from coming through whenever two or more inputs are high

What I need it to do is when input 1 goes high, it blocks the signal from input 2 and 3. When I2 goed high, it blocks I1 and I3, and when I3 goes high, it blocks I1 and I2.

Try this variant.

However, if all inputs go to 1 in the same program cycle, the Logo cannot make a priority decision.

You have to program priorities yourself.
