Hi Dear All,

I kindly ask you that where can i find a good sinumerik 840d sl plc programming tutorial, because to me it seems it is a very hidden knowledge, i don't find information about it on the net, when i ask programmers they dont like to answer to me. I dont know what is this? I can program siemens and omron plc-s, but i never ever touched a sinumerik ... from the plc programming side. and now i have a task, which is okay, but i need to read out data from the NC unit, like R parameter (i heard that i can use an NC var selector and i can add that to the simatic project, but i heard also that there are different methods for example to do it in a 810d) So the point is that i need the memory addresses, i should see the process of the sinumerik "plc" programming from the beginning to the end (just a basic example with the important points would be good) or at least some example but it is interesting that i cant find tutorials on the net. Why i cant find that? How do i find that? How do i get this information? I kindly ask you to help me! Thank you very much!! :)
