Hello, Be aware that M4.1 is a bit of MB4, but also a bit from MW4 (=MB4+MB5), or MW3 (= MB3+MB4), ... So, when making a cross reference, look also to these. For basics of programming look to this: Statement List (STL) for S7-300 and S7-400 Programming http://support.automation.siemens.com/WW/view/en/18653496 Ladder Logic (LAD) for S7-300 and S7-400 Programming http://support.automation.siemens.com/WW/view/en/18654395 Function Block Diagram (FBD) for S7-300 and S7-400 Programming http://support.automation.siemens.com/WW/view/en/18652644 |

@Ayman Elotaify You havent posted a screenshow. So, to summarize, if I cant find any byte, word or double word that contains this bit, then its of no use? @Sidney Thanks for the info. Why would then somone want to use peripheral addressing instead of using process image table? |
