Hi sandip.sp26, The S7-1200 does not have FIFO and AddToTable commands. You have to develop you own. But I am guessing you already knew that.. from there your question. My friend (Ste39) has given you an excellent source for getting "open source" implimentations, namely the OSCAT Library. Search for this on the web and then look at the given link too. These could however be overwhelming for some. We do not know you background.. it would help if we did. It would also help to know what you need to do with the code (how many elements for example). If you can code in Java / C++ / Pascal / ++ you will be familiar in the use of arrays. I would strongly suggest you use arrays with two index pointers. If you are not comfortable with structured language, we can approach this in LADDER or FBD. - - as I said, it will be most helpful to know what you background is and what you want to do. I hope this helps getting the conversation flowing. Greetings. w PS: This conversation would do better in the Step7 (TIA Portal) group. |
