Sorry, but I do not understand what you want.

Programming a LOGO! differs so strongly from a programming in a higher language, that certain functions can not be taken over and / or reproduced 1: 1.

First write, you want to know something about the UDF programming, now you write that you would rather know something about normal basic functions.

LOGO! can only be programmed in Ladder and FBD, in my opinion Ladder badly implemented and is also very faulty.

If you need examples of simple programs, check out this Siemens Website:

Application examples for LOGO!

 Hi ixo65

I probably asked too much in the beginning so it got confusing. There were 2 parts to the question...firstly, a simple FBD example as mentioned, then I wanted to turn that into a UDF. Lets forget the UDF, until a basic timing sequence is established.

I looked through nearly every example previously but could not find a multi segment sequence...not a single example. 

LOGO! is simple; I realise, but need a multi segment sequence...surely there must be people implementing such a simple request? Its is one of the most basic functions on a VFD.

Am I expecting too much? Surely it cant be that hard...but no examples on the website?

eg 

Output 1:

On for 10 seconds, Off for 5 secs, On for 12 secs, Off for 20 secs, on for 5 secs, off.

Thanks.

I hope I understood you correctly.

 Great! Yes...wow, its a very linear process. I was expecting something much more parameter driven.

Thanks so much ixo65.

BTW is 65 your birth date?
