Interlock

[acestu]

Hi,

I was just wondering if anybody could point me in the right direction for making an interlock please, what I mean is I have 2 push-buttons and 2 outputs I want it so that the 2 buttons cannot be pressed at the same time, it sounds simple but it is not as easy as it sounds.


thanks in advance

Hi,
I am not sure whether you are looking for something like the attached..here if you press one switch 2nd switch will be ineffective in that duration..and vice versa..

Thanks Enamul,

that is exactly what I was trying to do, I am trying to work out how you have done it now, What is the first calculation for before the loop ?


thanks

Hi,
First calculation box is for initialization..although the variables are initialized if sw are not pressed immediately after ON.
