UDFB multiple calls

[steliosliv]

Hello everyone,

I have a question regarding UDFBs. In my program I use a large function that has to be called multiple times. But when I run the program only the call that was first is successful the second call is never made. I tried a simple UDFB as shown below to test this, and I get the same problem. Is there a limit to call the same UDFB only one in the program or I am doing something wrong.

Thanks

I found that the problem was the positive edge of the frequency. I understand that if you call multiple functions which use the same positive edge only the first call will work.

hi steliosliv,

what happens if in your UDFB you put a "direct" contact ...-| |-...instead of the "positive" contact...-|P|-...?

edit: I just see now that you use the "frequency." variable and not an "user" variable that you can reset...

I'm not seeing this behavior with a quick test? I'm triggering a UDFB multiple times off Frequency.Frequency 1 (s) and all the UDFB instances are being called.

I believe @steliosliv refers to -P- contact inside of function. In that case you should make a bit for that positive edge and have a network like this in main before function is called several times:

Then you use normal contact of that new bit instead of -P- contact inside of function.

@Ness

That is because you inserted the positive edge outside of the UDFB1.

The problem is with the positive edge. I tried making a simple UDFB with a normal contact and it works fine

Yes that is correct, this way it works
