Hello kaspergl gut feeling tells me that you have NOT downloaded FC105 into the CPU (go one line down in the diagnostic buffer where it says "FC not loaded" and it'll tell you which FC is missing). As a "freshman" to S7 (which we all where at one stage), you may also find the following links helpful: SIMATIC Screencast Tutorials(note also the additional links to more trainig nvideos at the bottom of the page) ALL SIMATC Useful Manuals (Good for beginners on this Forum) Last but not least, you should find a "Step 7 - Working with Step 7" pdf shortcut via the Windows Start menu-> Simatic -> Documentation(it's quite a good "Step 7 for beginners"guide). |

OHHHH!!! I'm learning more and more.... I know why the output Q0.0 works!! I followed a toturial, and in this toturial the adresses are changed from default to 0: http://ezinearticles.com/?How-to-Program-a-Siemens-S7-300-Programmable-Logic-Controller&id=3652287 Don't ask me why! I also saw how to setup the analog inputs for 4-20mA signals!! It's all give more and more sense!! At start i couldn't figure out, how the PLC knows which signal I wanted to use, and I was looking for some sort of setup menu or code, as when I'm programming microprocessores.... |
