You can use a "triggered subsystem" block and set the trigger to "either". Use your signal value as the trigger.

Then inside the triggered subsystem, use a sum block to add one to the previous value of your counter. This will execute every time the trigger is satisfied (so it will add one every time your signal value changes.)

Do you mean like this?????

It doesnt work like this what should i change

First let's get your counter working.

As mentioned above, you must add one to the previous value of your counter, not to your signal.

(Also, I originally assumed your signal was boolean, but if this is not true, you can use an "enabled subsystem" and a detect change block instead of an "either" trigger).

Thank you very much for the quick help
