how to make indicator appear after a few times signal from boolen

[lemanlennon]

hello and good day to everyone.. 

 I'm trying to make a case change from false to true after receiving 3 or more signal from a boolen.

situation example, the signal is send but the case will change to true after three times of signal is receive then the turn to true case. If only two times of

signal is receive, the case will not change..

Does anyone have any suggestions or ideas how to create it? Or have another ways to solve it?

best regards,

You would use a shift register to track how many times the boolean is true.  If true, then increment.  If false, then don't.  If the value in the shift register =3 AND the value is true, then run your case structure.

Here is a small example showing what explained Ravens Fan.

It looks for 3 changing states from False to True, then stop the While loop.

You can easily insert this kind of logic into your code.

A great thanks to Ravens Fan and Olivier_L because show me more details... Its works.. But somehow either it will working with a PLC machine or not because the signal is very fast.. I'll try it tomorrow.By the way.Thanks.. 🙂
